How to Pass HOSA Clinical Nursing Exam — Study Tips

1. Active practice over passive reading. Work through timed blocks of 25–50 questions to simulate exam pacing and identify weak areas.
2. Read the question stem completely. Many exam errors come from misreading priorities (e.g., immediate safety vs. long-term care).
3. Eliminate distractors. Cross out obviously wrong options first to increase selection accuracy.
4. Use explanations to learn reasoning. After each block, review every explanation — understand why wrong answers are wrong.
5. Practice clinical skills in short daily drills. Pair MCQs with hands-on practice for things like measuring pulse, positioning, and safe transfers.
6. Simulate test conditions. Quiet environment, timed sessions, no external help — this trains concentration and stamina.
7. Create quick-reference sheets. Summarize vital sign ranges, PPE don/doff order, and the 6 rights of medication on 1–2 pages for rapid review.
8. Teach back. Explaining a question and its answer to a peer dramatically improves retention.

How this Practice Test is different

Unlike short quizzes or recycled question lists, this bank was written to reflect real HOSA Clinical Nursing scenarios with plausible distractors and clear clinical rationale. Each explanation highlights not only the correct action, but also the safety rationale and the typical clinical red flags — the sorts of details judges and examiners expect. Questions are grouped for targeted practice and include notation of which HOSA topic (e.g., vital signs, infection control, patient assessment) each item reinforces — saving you time and maximizing study efficiency. This means faster improvement, measurable progress, and content you can trust for 2025 competitions and regional/national events.

Common Exam Traps (and how to avoid them)

• Answering from memory, not from the stem. Always reread the final sentence — most traps hinge on a single word like “first,” “best,” or “least.”
  • Over-focusing on details. If a question asks for immediate action, prioritize safety and ABCs (airway, breathing, circulation).
  • Ignoring patient rights & ethics. HOSA scenarios often test privacy, consent, and dignity — document refusals and communicate respectfully.
  • Time mismanagement. Simulate timed blocks to build pacing and avoid rushing through later questions.

HOSA Clinical Nursing Sample Questions and Answers

Question 1. A patient with chronic obstructive pulmonary disease (COPD) suddenly becomes restless and confused while receiving oxygen therapy through a nasal cannula at 2 L/min. His respiratory rate drops from 22 to 10 breaths per minute, and his oxygen saturation rises from 86% to 98%. What is the nurse’s priority action?

A. Increase the oxygen flow rate to 4 L/min

B. Assess the patient and notify the healthcare provider of possible carbon dioxide retention

C. Place the patient in a supine position and continue monitoring

D. Encourage the patient to take rapid, deep breaths

Correct Answer: B

Explanation:
Some patients with advanced COPD have chronic carbon dioxide retention and may rely partly on low oxygen levels to stimulate breathing. A sudden improvement in oxygen saturation accompanied by decreased respirations, confusion, and restlessness can indicate worsening hypercapnia rather than clinical improvement. The nurse should immediately assess the patient and report the findings because respiratory failure can develop quickly. Increasing oxygen without evaluation may worsen the condition, while placing the patient supine can impair ventilation. Simply encouraging deep breaths does not address the underlying problem or the potential need for changes in oxygen therapy.

Question 2. A postoperative patient develops sudden shortness of breath, sharp chest pain, and anxiety while walking for the first time after surgery. Which assessment finding would most strongly support the nurse’s suspicion of a pulmonary embolism?

A. Bilateral crackles and pink frothy sputum

B. Sudden tachycardia with decreased oxygen saturation

C. Bradycardia with elevated blood pressure

D. Productive cough with thick yellow mucus

Correct Answer: B

Explanation:
A pulmonary embolism often occurs when a blood clot travels to the pulmonary circulation, causing an abrupt reduction in blood flow to part of the lung. Classic findings include sudden dyspnea, chest pain, tachycardia, tachypnea, anxiety, and hypoxemia. A sudden drop in oxygen saturation combined with a rapid heart rate is a significant warning sign requiring emergency intervention. Pink frothy sputum is more commonly associated with pulmonary edema, while productive yellow sputum suggests infection. Bradycardia is not a typical early sign of pulmonary embolism. Rapid recognition can be lifesaving because untreated emboli may lead to cardiovascular collapse.

Question 3. A nurse is preparing to administer regular insulin and NPH insulin in the same syringe. Which action is correct during medication preparation?

A. Withdraw NPH insulin before regular insulin

B. Shake both insulin vials vigorously before use

C. Withdraw regular insulin before NPH insulin

D. Mix the insulins only after both medications are injected separately into the patient

Correct Answer: C

Explanation:
When mixing regular insulin with NPH insulin, the accepted procedure is to inject air into the NPH vial first, then into the regular insulin vial, and withdraw the clear regular insulin before the cloudy NPH insulin. The principle of “clear before cloudy” helps prevent contamination of the regular insulin vial with intermediate-acting insulin, preserving the accuracy of future doses. Vigorously shaking insulin can create bubbles and alter dosing precision; cloudy insulin should instead be rolled gently. Administering the medications separately is unnecessary when a mixed dose is prescribed and properly prepared.

Question 4. A patient with bacterial meningitis is admitted to the emergency department. Which nursing intervention should receive the highest priority?

A. Encourage family members to remain at the bedside

B. Place the patient on droplet precautions immediately

C. Limit fluid intake to reduce intracranial pressure

D. Keep the room brightly lit for neurological assessments

Correct Answer: B

Explanation:
Bacterial meningitis can spread through respiratory droplets, making infection control an immediate priority for protecting healthcare workers, visitors, and other patients. The nurse should implement droplet precautions as soon as the condition is suspected, even before laboratory confirmation. Family members may visit but should follow appropriate protective measures. Fluid restriction is not routinely indicated and may worsen dehydration unless specifically prescribed. Bright lighting can increase discomfort because many patients experience photophobia. Rapid isolation, prompt antibiotic administration, and close neurological monitoring are essential components of effective nursing management.

Question 5. A patient receiving a blood transfusion suddenly reports chills, low back pain, and a feeling of impending doom. What should the nurse do first?

A. Slow the transfusion rate and continue to observe

B. Stop the transfusion and maintain intravenous access with normal saline

C. Administer an antipyretic medication immediately

D. Recheck the patient’s temperature after 30 minutes

Correct Answer: B

Explanation:
Chills, lumbar pain, and a sense of impending doom are classic signs of an acute hemolytic transfusion reaction, a potentially life-threatening emergency. The nurse’s first responsibility is to stop the transfusion immediately to prevent additional incompatible blood from entering the circulation. Intravenous access should be maintained with normal saline using new tubing according to facility policy while the healthcare provider and blood bank are notified. Simply slowing the transfusion could allow further hemolysis to occur. Antipyretics may be ordered later, but they do not address the underlying cause or prevent severe complications such as shock or acute kidney injury.

Question 6. A patient with a traumatic brain injury suddenly develops a blood pressure of 190/90 mmHg, a heart rate of 48 beats per minute, and irregular respirations. How should the nurse interpret these findings?

A. Early signs of septic shock

B. Evidence of Cushing’s triad indicating increased intracranial pressure

C. Normal physiological changes after head trauma

D. Symptoms of acute hypoglycemia

Correct Answer: B

Explanation:
Cushing’s triad consists of hypertension with a widening pulse pressure, bradycardia, and irregular respirations. It is a late and highly concerning sign of increased intracranial pressure (ICP) that may indicate impending brain herniation. The nurse should recognize this pattern as a neurological emergency requiring immediate intervention and notification of the healthcare provider. Septic shock typically presents with hypotension and tachycardia rather than hypertension and bradycardia. Hypoglycemia can cause altered mental status and sweating but does not characteristically produce this triad. Prompt action may help reduce further neurological damage and improve the patient’s outcome.

Question 7. A patient with chronic kidney disease has a serum potassium level of 6.7 mEq/L. Which electrocardiogram (ECG) finding should the nurse expect?

A. Flattened T waves and prolonged QT interval

B. Tall, peaked T waves

C. Presence of U waves and ST depression

D. Atrial flutter with sawtooth waves

Correct Answer: B

Explanation:
Hyperkalemia is a common and potentially fatal complication of advanced kidney disease because the kidneys cannot effectively eliminate potassium. One of the earliest and most recognized ECG manifestations is the appearance of tall, narrow, peaked T waves. As potassium levels continue to rise, the patient may develop prolonged PR intervals, widened QRS complexes, ventricular arrhythmias, and eventually cardiac arrest. U waves are commonly associated with hypokalemia, not hyperkalemia. Atrial flutter is a distinct arrhythmia unrelated to elevated potassium levels. Recognizing these ECG changes allows the nurse to anticipate urgent treatments such as calcium gluconate, insulin with dextrose, or dialysis.

Question 8. A patient receiving intravenous heparin therapy suddenly develops bleeding from the gums and blood in the urine. Which medication should the nurse anticipate administering?

A. Vitamin K

B. Protamine sulfate

C. Naloxone

D. Atropine sulfate

Correct Answer: B

Explanation:
Protamine sulfate is the specific antidote for heparin overdose. It binds with heparin and neutralizes its anticoagulant effect, helping to reduce active bleeding. The nurse should also stop the heparin infusion and monitor coagulation studies while preparing for emergency treatment. Vitamin K reverses the effects of warfarin, not heparin. Naloxone is used to reverse opioid toxicity, and atropine is primarily used for symptomatic bradycardia and certain poisonings. Rapid recognition of excessive anticoagulation is critical because uncontrolled bleeding can lead to shock, organ damage, and death.

Question 9. A patient with diabetes suddenly becomes pale, diaphoretic, and confused while waiting for lunch. The patient is awake and able to swallow. What is the nurse’s best initial action?

A. Administer regular insulin

B. Give 15 grams of a rapid-acting carbohydrate

C. Start an intravenous infusion of normal saline

D. Encourage the patient to rest until symptoms improve

Correct Answer: B

Explanation:
The patient’s symptoms strongly suggest hypoglycemia, a condition that requires immediate treatment to prevent seizures, loss of consciousness, or permanent neurological injury. If the patient is alert and can swallow safely, the recommended first intervention is to provide approximately 15 grams of a fast-acting carbohydrate, such as glucose tablets, fruit juice, or regular soda. Blood glucose should then be reassessed after about 15 minutes, and treatment repeated if necessary. Administering insulin would worsen hypoglycemia. Normal saline does not rapidly correct low blood sugar, and delaying treatment while waiting for symptoms to improve places the patient at unnecessary risk.

Question 10. A nurse is caring for a patient with suspected tension pneumothorax after a motor vehicle collision. Which assessment finding requires immediate intervention?

A. Tracheal deviation away from the injured side

B. Productive cough with white sputum

C. Diminished bowel sounds

D. Bilateral ankle edema

Correct Answer: A

Explanation:
Tension pneumothorax is a life-threatening emergency in which air becomes trapped within the pleural space, increasing pressure with each breath. As pressure builds, the mediastinum shifts, causing tracheal deviation away from the affected side. Other findings may include severe respiratory distress, absent breath sounds on the injured side, hypotension, distended neck veins, and cyanosis. Immediate decompression is necessary because untreated tension pneumothorax can rapidly lead to cardiovascular collapse. White sputum, diminished bowel sounds, and ankle edema are not hallmark features of this condition and do not require the same urgent response.

Question 11. A patient with liver cirrhosis suddenly becomes disoriented and begins having difficulty performing simple tasks. The nurse notices a flapping tremor when the patient extends the arms and dorsiflexes the wrists. Which laboratory result would most strongly support the suspected diagnosis?

A. Decreased serum sodium level

B. Elevated serum ammonia level

C. Increased serum calcium level

D. Decreased platelet count

Correct Answer: B

Explanation:
The patient’s confusion and asterixis (flapping tremor) are classic findings of hepatic encephalopathy, a neurological complication of severe liver dysfunction. When the liver cannot effectively convert ammonia into urea, ammonia accumulates in the bloodstream and crosses the blood-brain barrier, leading to altered mental status. Elevated serum ammonia supports this diagnosis, although treatment should not be delayed while awaiting laboratory confirmation. Management often includes lactulose to reduce ammonia absorption and identifying triggers such as gastrointestinal bleeding or infection. Low sodium and thrombocytopenia may occur in cirrhosis but are not the primary cause of hepatic encephalopathy.

Question 12. A patient who underwent a total thyroidectomy 6 hours ago suddenly reports tingling around the mouth and muscle cramps in the hands. Which nursing action is the highest priority?

A. Place the patient in a high-Fowler’s position

B. Assess for signs of hypocalcemia and prepare for calcium replacement

C. Encourage the patient to cough and deep breathe

D. Administer the prescribed opioid analgesic

Correct Answer: B

Explanation:
Accidental injury or removal of the parathyroid glands during thyroid surgery can result in acute hypocalcemia. Early manifestations include numbness or tingling around the mouth, muscle cramps, and paresthesia. If untreated, the patient may develop tetany, laryngospasm, seizures, and life-threatening airway obstruction. The nurse should immediately assess for additional signs, such as Chvostek’s and Trousseau’s signs, and prepare to administer intravenous calcium as prescribed. Although maintaining airway function is always important, simply changing the patient’s position or giving pain medication does not address the underlying electrolyte disturbance.

Question 13. A patient with septic shock has received adequate fluid resuscitation, but the mean arterial pressure (MAP) remains at 58 mmHg. Which physician order should the nurse expect to implement next?

A. Administer a vasopressor infusion

B. Restrict fluid intake

C. Place the patient on bed rest only

D. Administer a potassium supplement

Correct Answer: A

Explanation:
In septic shock, restoring adequate tissue perfusion is the primary goal. After appropriate fluid replacement, a persistent MAP below 65 mmHg indicates that vasopressor therapy is usually necessary to maintain blood pressure and support organ function. Medications such as norepinephrine are commonly used because they increase vascular tone and improve perfusion. Restricting fluids would worsen circulatory compromise, while bed rest alone offers no hemodynamic benefit. Potassium replacement is based on laboratory findings and is unrelated to the immediate management of refractory hypotension. Early recognition and intervention are essential to reduce the risk of multiple organ failure.

Question 14. A patient receiving continuous enteral tube feedings suddenly develops coughing, shortness of breath, and oxygen saturation of 88%. What is the nurse’s first action?

A. Increase the feeding rate to maintain nutrition

B. Stop the tube feeding and assess for aspiration

C. Flush the feeding tube with sterile water

D. Turn the patient onto the left side and continue feeding

Correct Answer: B

Explanation:
Coughing, respiratory distress, and decreased oxygen saturation during enteral feeding strongly suggest aspiration, a serious complication that can lead to aspiration pneumonia or respiratory failure. The nurse’s immediate priority is to stop the feeding to prevent additional material from entering the lungs and then assess the patient’s airway and respiratory status. The healthcare provider should be notified, and placement of the feeding tube may need to be verified. Increasing the feeding rate or continuing the feeding could worsen the situation. Flushing the tube does not address the emergency and may increase the risk of further aspiration.

Question 15. A patient with a history of long bone fracture suddenly develops petechiae on the chest, acute confusion, and severe respiratory distress. Which complication should the nurse suspect?

A. Fat embolism syndrome

B. Deep vein thrombosis

C. Acute renal failure

D. Myocardial infarction

Correct Answer: A

Explanation:
Fat embolism syndrome is a rare but serious complication that commonly occurs after fractures of long bones such as the femur. Fat droplets released from the bone marrow enter the bloodstream and obstruct small blood vessels, particularly in the lungs and brain. The classic triad includes respiratory distress, neurological changes, and a petechial rash, usually appearing within 24 to 72 hours after the injury. Deep vein thrombosis may cause leg swelling and pain but does not typically produce petechiae or acute confusion. Prompt recognition allows for supportive treatment, oxygen therapy, and close monitoring to prevent further deterioration.

Question 16. A patient with diabetic ketoacidosis (DKA) is receiving intravenous insulin therapy. Which laboratory finding indicates that the treatment is effective and the ketoacidosis is resolving?

A. Serum potassium increases from 5.0 to 5.8 mEq/L

B. Blood glucose decreases while the serum bicarbonate level and blood pH begin to normalize

C. Urine output decreases to less than 20 mL/hour

D. The white blood cell count rises above 20,000/mm³

Correct Answer: B

Explanation:
The primary goal in treating diabetic ketoacidosis is not simply lowering blood glucose but correcting the metabolic acidosis caused by ketone production. Effective treatment is demonstrated by improving serum bicarbonate levels, normalization of blood pH, closure of the anion gap, and a gradual reduction in blood glucose. Potassium levels often decrease during insulin therapy because potassium moves back into the cells, requiring close monitoring and replacement. Reduced urine output may indicate worsening kidney perfusion, while an elevated white blood cell count can occur with infection or stress and does not confirm resolution of DKA.

Question 17. A patient with a chest tube connected to a water-seal drainage system has continuous bubbling in the water-seal chamber. What is the nurse’s best interpretation of this finding?

A. The lung has fully re-expanded

B. An air leak is present in the drainage system or the patient

C. The chest tube is completely obstructed

D. This is an expected finding that requires no assessment

Correct Answer: B

Explanation:
Continuous bubbling in the water-seal chamber is abnormal and usually indicates an air leak somewhere within the chest drainage system or from the patient’s pleural space. The nurse should systematically assess the tubing connections, dressing, and drainage unit to identify the source of the leak. Intermittent bubbling may occur with exhalation in some patients recovering from a pneumothorax, but continuous bubbling requires investigation. A fully expanded lung would not typically produce this finding, and a completely obstructed chest tube would usually show little or no fluctuation. Prompt assessment helps prevent complications such as recurrent pneumothorax.

Question 18. A patient receiving magnesium sulfate for severe preeclampsia develops absent deep tendon reflexes, a respiratory rate of 8 breaths per minute, and decreased urine output. Which action should the nurse take first?

A. Continue the infusion and reassess in 30 minutes

B. Stop the magnesium sulfate infusion and prepare to administer calcium gluconate

C. Encourage the patient to increase oral fluid intake

D. Place the patient in Trendelenburg position

Correct Answer: B

Explanation:
Absent deep tendon reflexes, respiratory depression, and reduced urine output are hallmark signs of magnesium toxicity. Because magnesium is excreted by the kidneys, decreased urine output increases the risk of dangerous accumulation. The nurse should immediately discontinue the infusion and prepare to administer calcium gluconate, the antidote for magnesium toxicity, while notifying the healthcare provider. Continuing the infusion could result in respiratory arrest or cardiac complications. Oral fluids will not rapidly reverse toxicity, and Trendelenburg positioning does not address the underlying problem. Frequent monitoring of reflexes, respirations, and urine output is essential during magnesium therapy.

Question 19. A patient suddenly develops severe substernal chest pain that radiates to the left arm. The cardiac monitor shows ST-segment elevation. Which nursing intervention has the highest priority after activating the emergency response system?

A. Obtain a complete dietary history

B. Administer oxygen and prepare for rapid reperfusion therapy as prescribed

C. Encourage the patient to ambulate to improve circulation

D. Place a heating pad on the chest to reduce discomfort

Correct Answer: B

Explanation:
ST-segment elevation indicates an acute myocardial infarction caused by complete coronary artery occlusion. The priority is to preserve heart muscle by restoring blood flow as quickly as possible. After emergency activation, the nurse should administer oxygen if indicated, obtain vital signs, establish intravenous access, and prepare the patient for reperfusion treatment such as percutaneous coronary intervention or thrombolytic therapy according to medical orders. Delays increase the amount of irreversible myocardial damage. Ambulation would increase cardiac workload, while a dietary history and heating pad have no role in the emergency management of an acute STEMI.

Question 20. A patient with severe burns covering 35% of the body surface area is admitted to the emergency department. During the first 24 hours after injury, which assessment finding is the strongest indicator that fluid resuscitation is adequate?

A. Blood pressure of 150/90 mmHg

B. Urine output of approximately 30 to 50 mL/hour

C. Heart rate of 120 beats per minute

D. Body temperature of 38.5°C (101.3°F)

Correct Answer: B

Explanation:
Massive fluid loss occurs after major burns because increased capillary permeability allows plasma to shift into surrounding tissues. During the initial resuscitation phase, maintaining adequate organ perfusion is a critical goal. Urine output is one of the most reliable bedside indicators of effective fluid replacement, with an adult target generally around 30 to 50 mL per hour. Blood pressure alone may appear normal despite inadequate tissue perfusion because of compensatory mechanisms. Persistent tachycardia may indicate hypovolemia, pain, or stress, while fever is not a dependable measure of resuscitation adequacy during the early phase of burn management.

Question 21. A nurse is caring for a 72-year-old patient who underwent open reduction and internal fixation of a hip fracture. Twelve hours after surgery, the patient suddenly becomes restless and repeatedly asks, “Why can’t I catch my breath?” Assessment reveals an oxygen saturation of 89%, respiratory rate of 32/min, and fine crackles at the lung bases. Which action should the nurse perform first?

A. Administer the prescribed opioid for anxiety

B. Increase oral fluid intake

C. Assess airway and oxygenation while applying supplemental oxygen

D. Place the patient flat in bed

Correct Answer: C

Explanation:
The patient is demonstrating signs of acute respiratory compromise. Regardless of the underlying cause, the nursing priority follows the ABCs (Airway, Breathing, Circulation). Immediate assessment of airway patency and support of oxygenation are essential to prevent further hypoxia. Applying supplemental oxygen while conducting a focused respiratory assessment is appropriate. Opioids may worsen respiratory depression. Increasing oral fluids does not address the emergency, and lying flat may further impair ventilation. In real clinical settings, nurses must stabilize the patient first before determining whether the cause is pulmonary edema, embolism, or another postoperative complication.

Question 22. A patient receiving total parenteral nutrition (TPN) through a central venous catheter suddenly develops fever, chills, and hypotension. Which complication should the nurse suspect first?

A. Hyperthyroidism

B. Central line-associated bloodstream infection

C. Acute pancreatitis

D. Dumping syndrome

Correct Answer: B

Explanation:
Patients receiving TPN through central venous access are at increased risk for catheter-related bloodstream infections. Fever, chills, and hypotension may indicate developing sepsis, requiring immediate intervention. The nurse should stop the infusion if indicated by policy, assess the patient, notify the healthcare provider, and prepare for blood cultures and antibiotic therapy. Hyperthyroidism and pancreatitis do not commonly present in this context, while dumping syndrome is associated with gastric surgery rather than central venous nutrition. Strict aseptic technique during catheter care is critical for preventing this serious complication.

Question 23. A patient with a spinal cord injury at the T4 level develops severe hypertension, a pounding headache, facial flushing, and nasal congestion. What should the nurse do first?

A. Lay the patient flat and elevate the legs

B. Place the patient in a sitting position and assess for bladder distention

C. Administer oral fluids

D. Cover the patient with warm blankets

Correct Answer: B

Explanation:
The patient is experiencing autonomic dysreflexia, a potentially life-threatening complication of spinal cord injuries above T6. The first intervention is to sit the patient upright to lower blood pressure and immediately identify and remove the triggering stimulus, which is commonly bladder distention or bowel impaction. Laying the patient flat can worsen hypertension. Oral fluids and warming blankets do not treat the underlying problem. If untreated, autonomic dysreflexia can lead to seizures, stroke, or cardiac complications. Early recognition is an important competency in neurological nursing.

Question 24. A nurse is reviewing arterial blood gas results:

• pH: 7.28
• PaCO₂: 55 mmHg
• HCO₃⁻: 25 mEq/L

How should these results be interpreted?

A. Metabolic alkalosis

B. Respiratory acidosis without compensation

C. Respiratory alkalosis with compensation

D. Metabolic acidosis with compensation

Correct Answer: B

Explanation:
The pH is below normal, indicating acidosis. The PaCO₂ is elevated, showing that carbon dioxide retention is the primary cause. The bicarbonate level remains within the normal range, meaning the kidneys have not yet compensated for the imbalance. Therefore, the patient has uncompensated respiratory acidosis. This condition may result from respiratory depression, airway obstruction, or severe lung disease. Accurate interpretation of arterial blood gases is frequently tested because it guides urgent treatment decisions in critically ill patients.

Question 25. A patient receiving intravenous potassium chloride suddenly complains of burning at the infusion site. The nurse notes redness along the vein. What is the most appropriate action?

A. Increase the infusion rate

B. Stop the infusion and assess the intravenous site

C. Apply direct pressure and continue the medication

D. Dilute the medication by adding sterile water at the bedside

Correct Answer: B

Explanation:
Potassium chloride is highly irritating to blood vessels. Burning and redness may indicate infiltration or phlebitis, both of which require immediate attention. The infusion should be stopped, and the IV site assessed before further administration. Increasing the infusion rate may worsen tissue injury. Bedside dilution is unsafe and violates medication administration standards. Potassium should never be administered rapidly because serious cardiac arrhythmias may occur. Safe administration practices for high-alert medications are commonly evaluated in nursing examinations.

Question 26. A patient is admitted with suspected infective endocarditis. Which assessment finding is most characteristic of this condition?

A. Positive Chvostek’s sign

B. Painless red lesions on the palms and soles

C. Grey-Turner’s sign

D. Cullen’s sign

Correct Answer: B

Explanation:
Painless erythematous lesions on the palms and soles, known as Janeway lesions, are associated with infective endocarditis. They result from septic emboli and are an important clinical clue. Other findings may include fever, a new heart murmur, splinter hemorrhages, and Osler nodes. Chvostek’s sign indicates hypocalcemia, while Cullen’s and Grey-Turner’s signs are associated with internal abdominal bleeding and pancreatitis. Recognizing these physical findings helps nurses identify serious cardiovascular infections early.

Question 27. A patient receiving warfarin asks the nurse which food should be consumed consistently to help maintain stable anticoagulation therapy.

A. Foods high in vitamin K

B. Foods rich in sodium

C. Foods high in calcium

D. Foods containing large amounts of iron

Correct Answer: A

Explanation:
Vitamin K directly influences the effectiveness of warfarin. Patients do not need to avoid vitamin K-rich foods completely, but they should consume a relatively consistent amount from week to week to avoid significant fluctuations in anticoagulation levels. Sudden increases or decreases in foods such as spinach, kale, and broccoli may alter the INR and increase the risk of bleeding or clot formation. Sodium, calcium, and iron intake have no comparable effect on warfarin therapy.

Question 28. A nurse enters a patient’s room and finds the patient unresponsive. The cardiac monitor displays a chaotic, irregular waveform with no identifiable P waves or QRS complexes. Which intervention should occur immediately?

A. Begin synchronized cardioversion

B. Deliver unsynchronized defibrillation

C. Administer oral aspirin

D. Obtain a 12-lead ECG before treatment

Correct Answer: B

Explanation:
The rhythm described is ventricular fibrillation, a lethal arrhythmia that produces no effective cardiac output. Immediate defibrillation is the most effective treatment because it delivers an electrical shock to terminate the disorganized electrical activity and allow a normal rhythm to resume. Synchronized cardioversion is used for unstable tachyarrhythmias with a pulse. Waiting for a 12-lead ECG or administering aspirin would dangerously delay life-saving treatment. Rapid recognition of emergency cardiac rhythms is a major focus of clinical nursing examinations.

Question 29. A patient with syndrome of inappropriate antidiuretic hormone secretion (SIADH) is at greatest risk for which complication?

A. Hypernatremia

B. Severe dehydration

C. Cerebral edema resulting from hyponatremia

D. Hyperglycemia

Correct Answer: C

Explanation:
SIADH causes excessive water retention, diluting serum sodium concentrations and producing hyponatremia. Severe hyponatremia allows water to move into brain cells, causing cerebral edema that may result in headaches, confusion, seizures, coma, and death. The nurse should closely monitor neurological status and serum sodium levels while implementing prescribed fluid restrictions. Hypernatremia and dehydration are more commonly associated with diabetes insipidus. Hyperglycemia is unrelated to the primary mechanism of SIADH.

Question 30. During a medication reconciliation, a patient states, “I take digoxin every day, but lately everything has a yellow-green tint, and I have no appetite.” Which additional finding would most strongly support the nurse’s suspicion?

A. Bradycardia

B. Hypertension

C. Increased urine output

D. Hyperactive bowel sounds

Correct Answer: A

Explanation:
Yellow-green visual disturbances, anorexia, nausea, and fatigue are classic manifestations of digoxin toxicity. Bradycardia is another common finding because digoxin slows conduction through the atrioventricular node. Factors such as kidney impairment and hypokalemia increase the risk of toxicity by allowing higher concentrations of the medication to accumulate. The nurse should withhold the medication, assess the patient, and notify the healthcare provider. Hypertension and increased urine output are not characteristic findings, while hyperactive bowel sounds are not a hallmark of digoxin toxicity.
