Certified Pediatric Emergency Nurse (CPEN) Exam Practice Test

Our Certified Pediatric Emergency Nurse (CPEN) Exam Practice Test is created by qualified educators and experienced nursing-content reviewers to give you focused preparation for pediatric emergency nursing certification. With 850 practice questions, detailed rationales, clinical case scenarios, prioritization questions, and application-based problems, this resource is designed for nurses who want more than simple recall questions.

The question bank is built around the current CPEN exam framework and emphasizes the kind of clinical judgment needed when caring for infants, children, and adolescents in emergency settings. BCEN currently lists 175 CPEN exam items—150 scored and 25 unscored pretest items—with 110 of the 150 scored items required for a passing score under the current scoring standard.

What Is the CPEN Exam?

The Certified Pediatric Emergency Nurse (CPEN) exam validates specialized knowledge and clinical judgment for registered nurses caring for pediatric patients in emergency settings. The current CPEN framework reflects the evolving responsibilities of pediatric emergency nurses, including rapid triage, ongoing assessment, system-focused emergencies, multisystem presentations, special populations, and professional practice.

The current exam structure includes six major domains:

• Triage Process
• Assessment
• System-Focused Emergencies
• Special Considerations
• Multi-System Considerations
• Professional Issues

The current content outline places strong emphasis on pediatric emergency assessment, clinical deterioration, respiratory and cardiovascular emergencies, neurologic conditions, gastrointestinal and genitourinary emergencies, trauma, environmental emergencies, special populations, and professional nursing responsibilities.

What Is a CPEN Practice Test and How Can It Help With Preparation?

A CPEN practice test is a preparation resource for nurses working toward the Certified Pediatric Emergency Nurse (CPEN) certification. It gives candidates an opportunity to work through pediatric emergency nursing questions and apply their knowledge to situations that may require assessment, prioritization, intervention, and clinical judgment.

The purpose of practicing is not simply to count correct answers. Working through questions can help you identify subjects that deserve more attention, reinforce concepts you have already studied, and become more comfortable making decisions in pediatric emergency situations. BCEN itself recommends using a practice exam to identify weaker areas early in preparation and again as a final check before the certification exam.

A focused CPEN practice test can help you review areas such as:

• Pediatric triage and patient assessment
• Respiratory and cardiovascular emergencies
• Neurological emergencies and seizures
• Gastrointestinal and genitourinary emergencies
• Pediatric trauma and multisystem emergencies
• Toxicology and environmental emergencies
• Resuscitation and stabilization
• Pediatric-specific clinical considerations
• Family and patient considerations in emergency care

These areas reflect the broad clinical scope represented in the CPEN examination content outline, which includes system-focused emergencies, trauma and multisystem considerations, triage, assessment, and other pediatric emergency nursing responsibilities.

Using practice questions alongside your regular study materials can make preparation more active. When reviewing an incorrect answer, focus on why the correct option is appropriate, what information in the scenario matters most, and which underlying concept you need to review. This approach can turn practice sessions into targeted study rather than simply another test.

CPEN Practice Test Topics Covered

The question bank covers the major clinical and professional areas represented in the CPEN examination framework.

Triage Process

Questions focus on rapid pediatric triage, acuity determination, prioritization, reassessment, resource allocation, and recognizing children who require immediate intervention.

• Pediatric Assessment Triangle
• Acuity determination

BCEN specifically notes that pediatric emergency assessment is an ongoing, dynamic process rather than something that ends after triage.

System-Focused Emergencies

This is a major portion of pediatric emergency nursing knowledge and includes emergencies involving multiple body systems.

• Respiratory emergencies
• Asthma and severe bronchospasm
• Croup and upper-airway obstruction
• Foreign-body aspiration

Special Considerations

Pediatric emergency nursing requires more than knowing disease processes. Children differ from adults in anatomy, physiology, development, communication, medication dosing, equipment needs, and response to illness.

This practice test includes questions involving:

• Neonates and infants
• Toddlers and preschool children
• School-age children
• Adolescents
• Children with chronic medical conditions
• Children with developmental disabilities
• Children with technology dependence
• Children with tracheostomies
• Children with feeding tubes
• Children with congenital disorders
• Behavioral and mental-health emergencies
• Poisoning and toxicology
• Environmental emergencies
• Abuse and neglect considerations
• Family-centered pediatric emergency care

BCEN emphasizes that pediatric emergency patients have unique anatomical, physiologic, developmental, and psychosocial needs and may deteriorate rapidly.

Multi-System Considerations

Many of the most challenging pediatric emergency cases do not fit neatly into one body system. The practice questions therefore include complex presentations where several problems occur simultaneously.

• Pediatric sepsis
• Septic shock
• Multisystem inflammatory syndrome
• Major trauma
• Burns and inhalation injury
• Toxicologic emergencies
• Environmental exposure
• Drowning and submersion injury
• Heat illness
• Hypothermia
• Electrical and lightning injuries
• Rhabdomyolysis
• Multisystem organ dysfunction
• Complex resuscitation
• Post-resuscitation care

These scenarios are particularly useful for practicing the clinical reasoning required when several abnormal findings compete for attention.

Professional Issues

The CPEN examination also addresses responsibilities that extend beyond direct clinical treatment.

Practice questions address:

• Consent and refusal of treatment
• Adolescent confidentiality
• Patient advocacy
• Family-centered communication
• Ethical decision-making
• Legal responsibilities
• Documentation
• Medication safety
• Error prevention
• Safe handoff
• Interprofessional communication
• Workplace professionalism
• Patient privacy
• Cultural considerations
• Child protection concerns
• Disaster preparedness
• Evidence-based nursing practice
• Debriefing and quality improvement

How We Created This CPEN Practice Test

The questions were developed around the current CPEN examination content framework and pediatric emergency nursing knowledge, with emphasis on clinical application rather than simple definition-based recall.

Each question is designed to test a practical decision a pediatric emergency nurse may need to make:

• What should happen first?
• Which patient is most unstable?
• Which finding requires immediate escalation?
• What complication is most likely?
• Which intervention is safest?
• What assessment should be prioritized?
• Which finding indicates deterioration?
• What should the nurse reassess?
• Which response demonstrates appropriate professional practice?

BCEN explains that its certification examinations are developed through specialty nurse committees, role delineation studies, item writing, review, and psychometric processes. This PrepPool resource is independently created study material and is not an official BCEN exam or BCEN product.

Why the Questions Are More Than Simple Recall

A strong CPEN preparation resource should help you work through a clinical situation, not simply recognize a definition.

The questions therefore use:

• Patient vignettes
• Emergency-room scenarios
• Changing clinical conditions
• Priority-setting situations
• Pediatric assessment findings
• Medication and toxicology scenarios
• Trauma cases
• Multisystem presentations
• Parent and caregiver information
• Professional judgment situations
• “First action” questions
• “Most concerning finding” questions
• “Best response” questions

The explanations then connect the correct answer with the underlying pediatric emergency nursing principle.

Study Tips for the CPEN Exam

Start by learning the content areas, then move into mixed-question practice. BCEN recommends using the exam content outline as a preparation guide and using practice exams to identify weak areas.

• Review rationales even when you answer correctly.
• Practice prioritization questions regularly.
• Learn normal pediatric vital-sign patterns by age.
• Review weight-based medication principles.
• Understand pediatric shock rather than memorizing one blood-pressure value.
• Practice recognizing early deterioration.
• Review airway and respiratory emergencies frequently.
• Mix clinical domains during later study sessions.
• Complete timed practice before the actual exam.
• Revisit missed questions instead of simply repeating familiar ones.

CPEN Exam-Day Tips

The current CPEN examination contains 175 items, including 150 scored items and 25 unscored pretest items. BCEN states that the current passing standard is 110 correct answers among the 150 scored items.

On exam day:

• Read the entire clinical scenario before choosing an answer.
• Identify the immediate threat first.
• Look for airway, breathing, circulation, and neurologic deterioration.
• Pay attention to age and developmental stage.
• Do not overlook a changing clinical trend.
• Be cautious with answers that delay treatment unnecessarily.
• Do not choose an intervention simply because it is familiar.
• When two answers appear reasonable, determine which one addresses the most immediate priority.
• Manage your time without rushing through every question.
• Use the entire question stem to guide your decision.

Common CPEN Preparation Mistakes to Avoid

Many candidates spend too much time memorizing isolated facts and too little time practicing clinical reasoning.

Avoid:

• Studying only disease definitions
• Ignoring pediatric age differences
• Memorizing answers without understanding rationales
• Practicing only one question format
• Skipping professional-practice topics
• Ignoring toxicology and environmental emergencies
• Forgetting reassessment after an intervention
• Assuming normal blood pressure means the child is stable
• Treating children exactly like small adults
• Focusing only on the most obvious diagnosis
• Failing to recognize early shock
• Waiting for severe deterioration before escalating care

Who Can Use This CPEN Practice Test?

This resource is suitable for nurses preparing for the Certified Pediatric Emergency Nurse examination, including:

• Registered nurses preparing for CPEN certification
• Pediatric emergency nurses
• Emergency department nurses caring for children
• Nurses transitioning into pediatric emergency care
• Nurses reviewing pediatric emergency nursing concepts
• Experienced nurses preparing for specialty certification
• Nurses using practice questions for final CPEN review

BCEN currently requires a current, unencumbered RN license in the United States, a U.S. territory, Canada, or Australia, or an accepted international equivalent. BCEN recommends at least two years of specialty experience but states that this experience is recommended rather than required.

Prepare With Confidence for Your CPEN Exam

The CPEN exam tests more than memorization. It requires you to recognize unstable pediatric patients, interpret clinical findings, prioritize interventions, and apply emergency nursing knowledge across different ages and conditions.

Use this CPEN Practice Test to identify knowledge gaps, strengthen clinical judgment, practice realistic scenarios, and make your final preparation more focused. No practice resource can guarantee a passing result, but consistent practice combined with current clinical references and a structured study plan can make your preparation more effective.

CPEN Sample Questions and Answers

Question 1. A 4-year-old child is brought to the emergency department after suddenly developing severe coughing and stridor while eating peanuts. The child is conscious but cannot speak or produce an effective cough. Oxygen saturation is 88% on room air. Which intervention should the CPEN nurse anticipate first?

A. Administer nebulized albuterol
B. Perform abdominal thrusts
C. Encourage the child to drink water
D. Prepare for oral endotracheal intubation

Correct Answer: B.

Answer Explanation: Option B is correct because a conscious child with a severe foreign-body airway obstruction who cannot speak, cough effectively, or breathe requires immediate age-appropriate choking intervention. The priority is relieving the obstruction before hypoxemia progresses to respiratory arrest. Albuterol will not remove a mechanical obstruction, and giving fluids can worsen aspiration risk. Intubation may become necessary if ventilation cannot be restored, but it is not the initial intervention for a conscious child with a clearly recognized choking event. The nurse should rapidly activate assistance while performing the appropriate abdominal thrusts for the child’s age and clinical condition. Once the obstruction is relieved, the child still requires reassessment because residual airway injury, aspiration, or retained foreign material may be present.

Tip: When a child cannot speak or cough effectively, think severe airway obstruction first and intervene immediately.

Question 2. A 7-year-old with a history of asthma arrives in severe respiratory distress. The child is sitting upright, speaking only one or two words at a time, and has markedly diminished breath sounds bilaterally. After repeated bronchodilator therapy, the child becomes increasingly drowsy and the respiratory rate decreases. Which finding is most concerning?

A. Mild tachycardia
B. Decreased wheezing
C. Increasing somnolence with bradypnea
D. Persistent accessory muscle use

Correct Answer: C.

Answer Explanation: Option C is correct because increasing somnolence accompanied by a decreasing respiratory rate in a child with severe asthma suggests impending respiratory failure. A critically ill child may initially demonstrate pronounced wheezing and accessory muscle use, but as airflow becomes severely limited, wheezing can diminish because very little air is moving. A falsely reassuring reduction in wheezing should therefore never be interpreted as improvement when the child’s mental status and respiratory effort are worsening. The nurse should immediately recognize the deterioration, call for advanced airway support, provide appropriate oxygenation and ventilation support, and prepare for definitive airway management if required. Pediatric respiratory failure can develop rapidly because children have smaller airways and less respiratory reserve.

Tip: In severe asthma, less wheezing plus worsening mental status is a danger sign, not necessarily improvement.

Question 3. A 3-month-old infant presents with poor feeding, tachypnea, diaphoresis during feeds, and poor weight gain. The infant is pale and has hepatomegaly. Which underlying problem should the nurse suspect?

A. Congenital heart disease with heart failure
B. Acute gastroenteritis
C. Isolated iron-deficiency anemia
D. Viral upper respiratory infection

Correct Answer: A.

Answer Explanation: Option A is correct because the combination of tachypnea, diaphoresis with feeding, poor weight gain, pallor, and hepatomegaly is strongly suggestive of heart failure in an infant, potentially related to congenital heart disease. Feeding is a significant physical workload for young infants, and an infant with limited cardiac reserve may become tachypneic, sweaty, fatigued, and unable to consume enough calories. Hepatomegaly can occur because systemic venous congestion develops with heart failure. The nurse should prioritize cardiopulmonary assessment, oxygenation, perfusion, and signs of worsening respiratory distress while preparing for diagnostic evaluation and treatment. Congenital cardiac conditions are specifically included in the CPEN cardiovascular domain, along with shock, dysrhythmias, arrest, and circulatory support.

Tip: Sweating and tiring during feeds in an infant should prompt consideration of cardiac disease.

Question 4. A 9-year-old is brought to the emergency department after a bicycle crash. The child initially complained of a headache but is now difficult to arouse. The Glasgow Coma Scale has decreased from 14 to 9. The heart rate is 58/min, blood pressure is increasing, and respirations are becoming irregular. What is the nurse’s priority action?

A. Administer an oral analgesic
B. Place the child in a quiet room for observation
C. Prepare for immediate airway and neurologic management
D. Encourage oral fluids to prevent dehydration

Correct Answer: C.

Answer Explanation: Option C is correct because a declining level of consciousness after head trauma accompanied by bradycardia, hypertension, and irregular respirations is highly concerning for increased intracranial pressure and possible impending brain herniation. The immediate priorities are maintaining oxygenation and ventilation, protecting the airway, preventing secondary brain injury, and rapidly escalating care. The nurse should notify the appropriate emergency team and prepare for definitive airway management and urgent neurologic evaluation. Oral medications and fluids are inappropriate in a patient with significantly impaired consciousness because aspiration risk is substantial. Observation alone is unsafe because the child’s neurologic status is deteriorating. The CPEN neurological domain specifically includes traumatic brain injury, seizures, stroke, congenital conditions, and shunt dysfunction.

Tip: After pediatric head trauma, a falling GCS is a deterioration until proven otherwise.

Question 5. A 10-month-old infant presents with intermittent episodes of severe crying followed by drawing the knees toward the abdomen. The infant becomes pale during episodes and later passes a stool containing blood and mucus. Which condition should the nurse suspect?

A. Pyloric stenosis
B. Intussusception
C. Gastroesophageal reflux
D. Viral pharyngitis

Correct Answer: B.

Answer Explanation: Option B is correct because episodic abdominal pain with sudden crying, knee-to-chest positioning, pallor, and bloody mucus stool is characteristic of intussusception. The telescoping of one segment of intestine into another can cause bowel obstruction and compromise intestinal blood flow. The nurse should recognize this as an urgent abdominal emergency and prepare the child for diagnostic evaluation and definitive treatment. Pyloric stenosis typically presents in younger infants with progressive projectile, nonbilious vomiting rather than episodic severe abdominal pain and bloody stool. Gastroesophageal reflux does not explain the characteristic episodic pain and intestinal bleeding. The CPEN gastrointestinal domain specifically includes intestinal obstruction, including intussusception, volvulus, and pyloric stenosis.

Tip: Intermittent severe pain + knees drawn up + bloody mucus stool = think intussusception.

Question 6. A 15-year-old adolescent suddenly develops severe unilateral scrotal pain while playing basketball. The affected testicle is elevated, and the adolescent reports nausea. Which action is most appropriate?

A. Apply a warm compress and reassess in 1 hour
B. Encourage ambulation to improve circulation
C. Notify the provider immediately for suspected testicular torsion
D. Obtain a urine specimen before notifying the provider

Correct Answer: C.

Answer Explanation: Option C is correct because sudden severe unilateral testicular pain, an elevated testicle, and associated nausea are classic findings concerning for testicular torsion. Torsion compromises the testicular blood supply and is a time-sensitive emergency requiring immediate evaluation and treatment to maximize the chance of preserving testicular viability. Delaying evaluation for routine urine testing, observation, ambulation, or comfort measures can unnecessarily prolong ischemia. The nurse should promptly escalate the concern and prepare the adolescent for urgent diagnostic and surgical management according to the treating team’s direction. Testicular torsion is specifically identified within the CPEN genitourinary emergency content, making recognition of its presentation an important pediatric emergency nursing competency.

Tip: Sudden unilateral testicular pain is an emergency—do not delay evaluation for torsion.

Question 7. A 6-year-old child receiving chemotherapy presents to the emergency department with a temperature of 39.2°C (102.6°F). Laboratory results show an absolute neutrophil count of 300/mm³. The child appears tired but has no obvious localized infection. Which action has the highest priority?

A. Place the child on neutropenic precautions and wait for cultures
B. Administer an antipyretic and discharge if the fever resolves
C. Initiate urgent evaluation and treatment for suspected febrile neutropenia
D. Encourage oral fluids and repeat the temperature in 4 hours

Correct Answer: C.

Answer Explanation: Option C is correct because fever in a child with profound neutropenia is a medical emergency because the inflammatory response may be minimal even when a serious infection is present. An absolute neutrophil count of 300/mm³ represents severe neutropenia, and the child’s fever requires prompt assessment, cultures as indicated, and rapid initiation of empiric antimicrobial therapy according to institutional protocol. Waiting for cultures before beginning treatment can allow an occult infection to progress rapidly to sepsis. Antipyretics may improve comfort but do not treat the underlying infection, and discharge is inappropriate. The CPEN hematology/oncology domain specifically includes fever and neutropenia as well as other oncologic emergencies such as tumor lysis syndrome.

Tip: Fever + severe neutropenia = treat as an emergency, even when the child looks relatively well.

Question 8. A 5-year-old child with known congenital adrenal hyperplasia presents with vomiting, lethargy, hypotension, and weakness after several days of gastroenteritis. Laboratory testing shows hyponatremia and hyperkalemia. Which emergency should the nurse suspect?

A. Diabetic ketoacidosis
B. Adrenal crisis
C. Acute nephrotic syndrome
D. Hyperthyroidism

Correct Answer: B.

Answer Explanation: Option B is correct because a child with congenital adrenal hyperplasia is at risk for adrenal insufficiency and adrenal crisis, particularly during significant physiologic stress such as infection or persistent vomiting. Hypotension, lethargy, vomiting, hyponatremia, and hyperkalemia are important clues to inadequate cortisol and aldosterone activity. This condition requires immediate recognition and treatment according to emergency protocols, including appropriate corticosteroid replacement and hemodynamic support. Delayed treatment can result in progressive shock and cardiovascular collapse. Diabetic ketoacidosis typically produces hyperglycemia and metabolic acidosis, while the electrolyte pattern described here is particularly concerning for adrenal insufficiency. Congenital adrenal disorders and acquired diabetes are specifically included in the CPEN endocrine/metabolic domain.

Tip: In a child with adrenal disease, vomiting + hypotension + hyponatremia/hyperkalemia should trigger concern for adrenal crisis.

Question 9. A 2-day-old newborn presents to the emergency department with poor feeding, temperature instability, lethargy, and grunting respirations. The parents report that the infant has become progressively less responsive over the past several hours. Which nursing priority is most appropriate?

A. Delay treatment until a definitive infectious organism is identified
B. Maintain thermoregulation while rapidly evaluating and treating possible neonatal infection
C. Give oral formula to correct possible dehydration
D. Place the newborn under phototherapy immediately

Correct Answer: B.

Answer Explanation: Option B is correct because newborns can deteriorate rapidly with serious infection and may present with nonspecific findings such as poor feeding, temperature instability, lethargy, respiratory distress, and altered responsiveness rather than a classic fever. Maintaining a stable temperature is important because hypothermia can worsen metabolic stress, while rapid assessment and treatment of suspected neonatal infection are essential. Waiting for organism identification can dangerously delay therapy. Oral feeding is inappropriate when the infant is significantly lethargic and has respiratory distress because aspiration risk may be increased. Phototherapy is used for clinically significant hyperbilirubinemia, but the presentation described is primarily concerning for infection and systemic deterioration. Neonatal infection, thermoregulation, fluid-electrolyte imbalance, and newborn resuscitation are included in the CPEN Special Considerations domain.

Tip: In newborns, temperature instability and poor feeding can be early signs of serious infection.

Question 10. A 14-year-old is brought to the emergency department after intentionally ingesting an unknown quantity of acetaminophen several hours earlier. The adolescent is awake and says, “I don’t want anyone to know.” Which nursing action is the priority?

A. Respect confidentiality and withhold the information from the treatment team
B. Assess immediate safety and initiate emergency toxicology evaluation
C. Wait until the adolescent’s parents arrive before obtaining any history
D. Reassure the adolescent that no treatment is necessary if symptoms are absent

Correct Answer: B.

Answer Explanation: Option B is correct because intentional ingestion requires immediate attention to both medical toxicity and the adolescent’s safety. Acetaminophen poisoning may initially produce few or nonspecific symptoms despite potentially serious delayed hepatic injury, so absence of symptoms does not establish safety. The nurse should obtain as accurate a history as possible, determine timing and amount when available, initiate appropriate toxicology evaluation, and address suicide risk and immediate safety. Confidentiality is important in adolescent care, but it does not prevent the healthcare team from taking necessary action when there is a serious risk of harm. The CPEN toxicology domain includes intentional and unintentional poisoning, while behavioral health content includes self-injury and suicidal ideation.

Tip: With intentional ingestion, address both the toxic exposure and the risk of self-harm.

Question 11. A 12-year-old develops generalized urticaria, facial swelling, wheezing, and hypotension minutes after receiving an antibiotic. Which medication should the nurse administer first?

A. Diphenhydramine
B. Methylprednisolone
C. Albuterol
D. Intramuscular epinephrine

Correct Answer: D.

Answer Explanation: Option D is correct because the child has signs of severe anaphylaxis involving multiple organ systems, including airway/respiratory compromise and cardiovascular instability. Intramuscular epinephrine is the first-line treatment because it rapidly counteracts airway edema, bronchoconstriction, and vasodilation associated with anaphylaxis. Antihistamines and corticosteroids may have adjunctive roles but do not replace epinephrine and should never delay its administration. Albuterol can help persistent bronchospasm but does not adequately treat the systemic vasodilatory and upper-airway effects of anaphylaxis. The nurse should simultaneously support airway and circulation, provide oxygen as indicated, establish appropriate access, and prepare for additional resuscitative interventions. Anaphylaxis is specifically listed within the CPEN Multi-System Considerations domain.

Tip: Epinephrine first for anaphylaxis with airway, breathing, or circulation compromise.

Question 12. A 6-year-old is brought to the emergency department after being submerged in a swimming pool. The child is coughing, hypoxic, and has altered mental status. Which intervention should the nurse prioritize?

A. Obtain a detailed history before initiating treatment
B. Focus first on airway, breathing, and oxygenation
C. Encourage the child to walk to improve lung expansion
D. Give oral fluids to replace fluid lost during submersion

Correct Answer: B.

Answer Explanation: Option B is correct because a child rescued from submersion who has hypoxemia, coughing, and altered mental status requires immediate assessment and stabilization of airway and breathing. Hypoxia is a major contributor to morbidity after submersion injury, so oxygenation and ventilation take priority over obtaining a complete history or administering oral fluids. The nurse should rapidly assess respiratory effort, oxygen saturation, mental status, and circulation while preparing appropriate respiratory support. Even if the child’s initial condition improves, continued observation and reassessment are important because respiratory complications can evolve after the initial event. Submersion injuries are specifically included in the CPEN Multi-System Considerations domain.

Tip: For submersion injury, remember oxygenation and ventilation are immediate priorities.

Question 13. A 9-year-old arrives with fever, tachycardia, delayed capillary refill, altered mental status, and cool extremities. Blood pressure is initially within the normal range for age. The nurse suspects septic shock. Which interpretation is most appropriate?

A. Normal blood pressure excludes shock
B. The child is stable because hypotension is absent
C. Compensated shock may be present despite preserved blood pressure
D. Septic shock occurs only after hypotension develops

Correct Answer: C.

Answer Explanation: Option C is correct because children can maintain blood pressure through compensatory mechanisms until significant cardiovascular compromise has already developed. Tachycardia, delayed capillary refill, altered mental status, cool extremities, and abnormal perfusion are concerning signs of shock even when systolic blood pressure remains within the expected range. Waiting for hypotension can delay recognition and treatment of pediatric septic shock. The nurse should promptly escalate care, support airway and oxygenation, obtain appropriate vascular access, and anticipate timely sepsis-directed interventions according to the clinical setting and protocol. Pediatric sepsis is specifically included in the CPEN Multi-System Considerations domain, emphasizing the importance of recognizing deterioration before late-stage hypotension occurs.

Tip: Hypotension is a late sign of pediatric shock. Assess perfusion, mental status, and trends.

Question 14. A 13-year-old with a forearm fracture reports escalating pain despite analgesia. The nurse notes increasing pain with passive finger extension, tense swelling of the forearm, and new paresthesia. Which action is the priority?

A. Elevate the arm above the level of the heart and reassess later
B. Apply a heating pad to relax the muscles
C. Notify the provider immediately about possible compartment syndrome
D. Encourage active range-of-motion exercises

Correct Answer: C.

Answer Explanation: Option C is correct because escalating pain that is disproportionate to the injury, pain with passive stretch, tense swelling, and sensory changes are concerning for acute compartment syndrome. Rising pressure within a closed fascial compartment can impair tissue perfusion and cause irreversible nerve and muscle injury if treatment is delayed. The nurse should immediately communicate the findings and prepare for urgent evaluation and intervention. Routine reassessment or exercises are inappropriate when compartment syndrome is suspected. Excessive elevation may also reduce arterial perfusion in an already compromised extremity, so the priority is rapid recognition and escalation rather than attempting to manage the condition independently. Compartment syndrome is specifically included within the CPEN musculoskeletal trauma content.

Tip: Pain out of proportion + passive-stretch pain = think compartment syndrome.

Question 15. A 6-year-old requires procedural sedation for repair of a deep facial laceration. Shortly after sedation begins, the child develops snoring respirations, decreased chest movement, and oxygen saturation of 89%. What should the nurse do first?

A. Continue the procedure because the oxygen saturation may improve
B. Stimulate the child, reposition the airway, and provide appropriate airway support
C. Administer an additional sedative dose
D. Leave the child unattended while obtaining emergency equipment

Correct Answer: B.

Answer Explanation: Option B is correct because snoring, reduced chest movement, and declining oxygen saturation during procedural sedation indicate possible upper-airway obstruction and respiratory compromise. The nurse must immediately prioritize airway assessment and intervention rather than allowing the procedure to continue. Repositioning and appropriate stimulation may relieve upper-airway obstruction, while oxygen and additional airway support should be provided as clinically indicated. Emergency equipment and appropriately trained personnel should be immediately available throughout pediatric procedural sedation because children can progress quickly from partial airway obstruction to apnea. Giving more sedative could worsen respiratory depression. Procedural sedation is specifically identified in the CPEN Multi-System Considerations domain, and safe practice requires continuous monitoring and rapid response to deterioration.

Tip: During pediatric sedation, airway problems take priority over completing the procedure.
