PCCN 570 Sample Questions and Answers

Question 1: Cardiovascular – Heart Failure

A progressive care patient with acute decompensated heart failure develops worsening dyspnea and crackles in both lung bases. Which intervention should the nurse prioritize?

A. Administer IV fluids
B. Elevate the head of the bed and administer oxygen
C. Encourage ambulation
D. Provide high-sodium diet

Correct Answer: B

Explanation:
Elevating the head of the bed and administering oxygen are immediate interventions for acute dyspnea caused by pulmonary congestion in heart failure. Patients with fluid overload often experience impaired gas exchange due to pulmonary edema. Positioning the patient upright reduces venous return and decreases pulmonary congestion, improving oxygenation. Supplemental oxygen supports tissue perfusion while additional treatments such as diuretics or vasodilators are initiated. IV fluids would worsen fluid overload, ambulation increases oxygen demand during respiratory distress, and sodium intake contributes to fluid retention. Prioritizing airway and breathing follows the ABC framework commonly used in progressive and critical care settings.

Question 2: Pulmonary – ARDS

A patient with acute respiratory distress syndrome (ARDS) requires mechanical ventilation. Which ventilator strategy is most appropriate?

A. High tidal volumes to improve oxygenation
B. Low tidal volume ventilation with PEEP
C. Minimal oxygen therapy
D. High respiratory rate without PEEP

Correct Answer: B

Explanation:
Low tidal volume ventilation combined with positive end-expiratory pressure (PEEP) is the standard strategy for ARDS management. This approach prevents alveolar overdistention and reduces ventilator-induced lung injury while maintaining adequate oxygenation. PEEP helps keep alveoli open during expiration, improving gas exchange and preventing collapse. High tidal volumes increase the risk of barotrauma and volutrauma, worsening lung injury. Minimal oxygen therapy would not adequately support oxygenation in severe respiratory failure. Proper ventilator management in ARDS focuses on lung-protective strategies, careful monitoring of oxygenation parameters, and frequent assessment of respiratory mechanics.

Question 3: Cardiovascular – Dysrhythmia

A patient on telemetry develops atrial fibrillation with rapid ventricular response (RVR). Which medication is commonly administered first to control heart rate?

A. Atropine
B. Diltiazem
C. Epinephrine
D. Adenosine

Correct Answer: B

Explanation:
Diltiazem, a calcium channel blocker, is frequently used to control ventricular rate in atrial fibrillation with rapid ventricular response. It slows conduction through the atrioventricular (AV) node, reducing heart rate and improving cardiac output. Rate control is a priority because sustained tachycardia can compromise cardiac function and increase myocardial oxygen demand. Adenosine is typically used for supraventricular tachycardia rather than atrial fibrillation. Atropine increases heart rate and would worsen tachycardia. Epinephrine is used for cardiac arrest or severe hypotension, not rate control in atrial fibrillation.

Question 4: Endocrine – Diabetic Ketoacidosis

A patient with diabetic ketoacidosis (DKA) begins insulin therapy. Which laboratory value indicates the treatment is effective?

A. Increasing serum glucose
B. Rising serum potassium
C. Decreasing serum ketones and glucose
D. Increasing serum bicarbonate deficit

Correct Answer: C

Explanation:
Effective treatment of diabetic ketoacidosis is demonstrated by decreasing blood glucose levels and reduction of ketone bodies in the bloodstream. DKA occurs when insulin deficiency leads to fat metabolism and ketone production, causing metabolic acidosis. Insulin therapy stops ketone production and allows glucose to enter cells for energy. As treatment progresses, metabolic acidosis improves and serum bicarbonate levels normalize. Monitoring electrolytes, particularly potassium, is also critical because insulin therapy can shift potassium into cells and lead to hypokalemia. Declining ketone levels and improved glucose control indicate the therapy is working.

Question 5: Renal – Acute Kidney Injury

A patient with acute kidney injury (AKI) has decreased urine output and elevated creatinine. Which nursing intervention is most important?

A. Restrict fluid intake completely
B. Monitor fluid balance and electrolyte levels
C. Encourage high-protein diet
D. Increase potassium intake

Correct Answer: B

Explanation:
Close monitoring of fluid balance and electrolyte levels is essential for patients with acute kidney injury. AKI impairs the kidneys’ ability to regulate fluid, electrolytes, and waste products. Nurses must carefully track intake and output, monitor weight changes, and evaluate laboratory values such as potassium, sodium, and creatinine. Hyperkalemia is a common complication and can lead to life-threatening arrhythmias. Completely restricting fluids may worsen kidney perfusion, and increased potassium intake would be dangerous in patients with impaired excretion. A balanced approach to fluid management and electrolyte monitoring is critical in progressive care settings.

Question 6: Neurology – Stroke

A patient presents with sudden unilateral weakness and slurred speech. Which action should the nurse perform first?

A. Administer aspirin
B. Perform rapid neurological assessment
C. Provide oral fluids
D. Schedule physical therapy

Correct Answer: B

Explanation:
A rapid neurological assessment is the first priority when stroke symptoms appear. Early recognition and evaluation allow healthcare providers to determine stroke type and initiate time-sensitive treatments such as thrombolytics. The nurse should assess level of consciousness, motor function, speech, and pupil response. Immediate identification ensures the patient receives appropriate diagnostic imaging and intervention within the therapeutic window. Administering aspirin without confirming stroke type could be harmful in hemorrhagic stroke. Oral fluids increase aspiration risk, and physical therapy is not an immediate priority. Rapid assessment and activation of stroke protocols significantly improve patient outcomes.

Question 7: Hematology – DIC

A patient with disseminated intravascular coagulation (DIC) shows bleeding from IV sites and bruising. What is the underlying cause?

A. Excessive platelet production
B. Widespread clotting factor activation
C. Increased red blood cell production
D. Decreased fibrinolysis

Correct Answer: B

Explanation:
Disseminated intravascular coagulation occurs when widespread activation of the clotting cascade leads to the formation of numerous microclots throughout the body. This process consumes platelets and clotting factors, eventually causing severe bleeding. The condition is often triggered by sepsis, trauma, or severe illness. As clotting factors become depleted, patients develop bleeding from IV sites, surgical wounds, and mucous membranes. Treatment focuses on addressing the underlying cause while supporting coagulation with blood products if necessary. Early recognition is crucial because DIC can rapidly progress to multi-organ failure.

Question 8: Respiratory – Pulmonary Embolism

Which symptom is most commonly associated with pulmonary embolism?

A. Gradual weight gain
B. Sudden shortness of breath
C. Chronic cough
D. Bradycardia

Correct Answer: B

Explanation:
Sudden shortness of breath is one of the hallmark symptoms of pulmonary embolism. A pulmonary embolism occurs when a blood clot obstructs a pulmonary artery, impairing oxygen exchange and causing acute respiratory distress. Other symptoms may include chest pain, tachycardia, and hypoxia. Risk factors include prolonged immobility, surgery, and deep vein thrombosis. Rapid recognition is essential because pulmonary embolism can quickly become life-threatening. Treatment typically includes anticoagulation therapy, oxygen support, and in severe cases, thrombolytic therapy or surgical intervention.

Question 9: Cardiovascular – Hemodynamics

Which parameter best reflects left ventricular preload?

A. Central venous pressure
B. Pulmonary artery wedge pressure
C. Heart rate
D. Mean arterial pressure

Correct Answer: B

Explanation:
Pulmonary artery wedge pressure (PAWP) is used as an indirect measure of left ventricular preload. It reflects the pressure in the left atrium and indicates the volume of blood returning to the heart before contraction. Monitoring preload helps clinicians assess fluid status and cardiac function, particularly in critically ill patients. Elevated PAWP may indicate fluid overload or heart failure, while low values may suggest hypovolemia. Central venous pressure primarily reflects right ventricular preload rather than left ventricular filling pressures.

Question 10: GI – Acute Pancreatitis

Which laboratory finding is most indicative of acute pancreatitis?

A. Elevated amylase and lipase
B. Low hemoglobin
C. Elevated bilirubin only
D. Low sodium

Correct Answer: A

Explanation:
Elevated serum amylase and lipase levels are key indicators of acute pancreatitis. These digestive enzymes are released into the bloodstream when the pancreas becomes inflamed. Lipase is considered more specific for pancreatic injury. Patients often present with severe epigastric pain radiating to the back, nausea, and vomiting. Early diagnosis is important because complications may include infection, organ failure, or necrosis. Management typically involves supportive care, fluid resuscitation, pain control, and nutritional support while the pancreas heals.

Question 11: Sepsis Recognition

A progressive care patient develops fever, tachycardia, hypotension, and an elevated lactate level. Which condition should the nurse suspect?

A. Hypovolemic shock
B. Septic shock
C. Cardiogenic shock
D. Neurogenic shock

Correct Answer: B

Explanation:
Septic shock is a severe form of sepsis characterized by persistent hypotension and elevated serum lactate despite adequate fluid resuscitation. Early symptoms often include fever, tachycardia, hypotension, and signs of poor tissue perfusion. Lactate levels rise when tissues are deprived of oxygen and shift to anaerobic metabolism. Early recognition is critical because rapid treatment with fluids, antibiotics, and vasopressors significantly improves survival. Progressive care nurses must closely monitor vital signs, mental status, urine output, and laboratory markers such as lactate and procalcitonin to detect deterioration quickly.

Question 12: Electrolyte Imbalance – Hyperkalemia

Which ECG change is most commonly associated with hyperkalemia?

A. Flattened T waves
B. Tall peaked T waves
C. Prolonged PR interval
D. ST depression

Correct Answer: B

Explanation:
Tall, peaked T waves are a classic early ECG finding in hyperkalemia. Elevated potassium levels affect cardiac electrical conduction by altering the resting membrane potential of myocardial cells. As potassium levels continue to rise, additional ECG changes may occur, including widened QRS complexes, prolonged PR intervals, and eventually ventricular arrhythmias or cardiac arrest. Hyperkalemia is often caused by renal failure, certain medications, or tissue breakdown. Rapid identification and treatment with interventions such as calcium gluconate, insulin with glucose, or dialysis are essential to prevent life-threatening cardiac complications.

Question 13: Mechanical Ventilation Alarm

A high-pressure alarm sounds on a patient’s mechanical ventilator. What is the most likely cause?

A. Disconnected tubing
B. Air leak in circuit
C. Patient coughing or airway obstruction
D. Low oxygen supply

Correct Answer: C

Explanation:
A high-pressure ventilator alarm typically indicates increased resistance to airflow in the airway or ventilator circuit. Common causes include patient coughing, biting the endotracheal tube, mucus plugs, bronchospasm, or kinks in the ventilator tubing. These conditions increase airway resistance and require higher pressure to deliver the set tidal volume. The nurse should quickly assess the patient for signs of distress, check the airway for secretions, and evaluate the ventilator tubing. Disconnected tubing or air leaks usually trigger low-pressure alarms rather than high-pressure alarms.

Question 14: Acute Coronary Syndrome

A patient presents with chest pain suspected to be acute coronary syndrome. Which medication should be administered first?

A. Morphine
B. Aspirin
C. Furosemide
D. Amiodarone

Correct Answer: B

Explanation:
Aspirin is one of the first medications administered to patients with suspected acute coronary syndrome. It works by inhibiting platelet aggregation, reducing clot formation in coronary arteries. Early aspirin administration significantly lowers mortality in myocardial infarction by improving coronary blood flow. Patients are typically instructed to chew the tablet for faster absorption. Other treatments such as oxygen, nitrates, and morphine may also be used depending on the patient’s symptoms and condition. Prompt recognition and treatment of ACS are critical to limit myocardial damage.

Question 15: Stroke Treatment

A patient arrives at the emergency department within one hour of stroke symptom onset. Which treatment may be considered?

A. Thrombolytic therapy
B. Immediate surgery
C. Anticoagulant infusion without imaging
D. Sedative administration

Correct Answer: A

Explanation:
Thrombolytic therapy, such as tissue plasminogen activator (tPA), may be administered to eligible patients with ischemic stroke if they arrive within the appropriate treatment window. Early treatment dissolves the clot blocking cerebral blood flow and can significantly reduce neurological damage. Before administering thrombolytics, clinicians must confirm the stroke type using brain imaging to rule out hemorrhage. Strict eligibility criteria are followed to minimize bleeding risk. Rapid recognition of stroke symptoms and activation of stroke protocols allow healthcare teams to deliver time-sensitive treatment effectively.

Question 16: Renal Replacement Therapy

Which condition is a common indication for initiating dialysis in acute kidney injury?

A. Mild dehydration
B. Hyperkalemia resistant to treatment
C. Low blood pressure
D. Mild anemia

Correct Answer: B

Explanation:
Dialysis is often initiated in acute kidney injury when life-threatening complications occur that cannot be managed with conservative treatment. Severe hyperkalemia resistant to medical therapy is a major indication because elevated potassium can cause dangerous cardiac arrhythmias. Other indications include severe metabolic acidosis, fluid overload unresponsive to diuretics, and accumulation of toxins such as urea. Dialysis helps remove waste products, correct electrolyte imbalances, and restore fluid balance. Early recognition of these complications allows timely intervention and prevents further organ damage.

Question 17: Post-Operative Hemorrhage

Which finding most strongly suggests post-operative internal bleeding?

A. Mild pain at incision site
B. Increasing heart rate and decreasing blood pressure
C. Slight fever
D. Reduced appetite

Correct Answer: B

Explanation:
Tachycardia combined with falling blood pressure is a classic sign of internal bleeding and possible hypovolemic shock. After surgery, patients should be closely monitored for early signs of hemorrhage. As blood volume decreases, the body compensates by increasing heart rate to maintain cardiac output. If bleeding continues, blood pressure drops due to decreased circulating volume. Other symptoms may include pale skin, dizziness, and decreased urine output. Rapid identification allows healthcare providers to intervene quickly with fluid resuscitation, blood transfusion, or surgical management if necessary.

Question 18: ICU Delirium

Which tool is commonly used to assess delirium in critically ill patients?

A. Glasgow Coma Scale
B. CAM-ICU assessment
C. Braden Scale
D. Morse Fall Scale

Correct Answer: B

Explanation:
The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is widely used to detect delirium in critically ill patients. Delirium is a common complication in progressive and intensive care units and is associated with increased mortality, longer hospital stays, and long-term cognitive impairment. The CAM-ICU evaluates acute mental status changes, inattention, altered consciousness, and disorganized thinking. Early detection allows healthcare teams to address contributing factors such as infection, medications, sleep deprivation, or metabolic imbalance.

Question 19: Ethical Nursing Practice

A patient refuses a recommended medical treatment despite understanding the risks. What principle should guide the nurse’s response?

A. Beneficence
B. Autonomy
C. Justice
D. Nonmaleficence

Correct Answer: B

Explanation:
Autonomy refers to the patient’s right to make informed decisions about their own healthcare. Even if the healthcare team believes a treatment would benefit the patient, competent individuals have the legal and ethical right to refuse medical care. The nurse’s role is to ensure the patient understands the risks, benefits, and alternatives before making a decision. Respecting autonomy supports patient dignity and promotes trust in the healthcare relationship. Nurses may advocate for the patient, clarify information, and document the decision appropriately.

Question 20: Multisystem Organ Failure

Which condition most commonly leads to multisystem organ failure in critically ill patients?

A. Mild dehydration
B. Severe sepsis or septic shock
C. Minor infection
D. Hypertension

Correct Answer: B

Explanation:
Severe sepsis and septic shock are among the most common causes of multisystem organ failure. When infection triggers an overwhelming inflammatory response, widespread tissue damage and impaired blood flow can occur. This process disrupts oxygen delivery to organs such as the kidneys, lungs, liver, and heart. As organ function deteriorates, patients may develop acute respiratory distress syndrome, kidney failure, or cardiovascular collapse. Early recognition of sepsis, rapid antibiotic administration, and aggressive supportive care are essential to prevent progression to organ failure.
