Advanced PCCN (Progressive Care Certified
Nurse) Multiple Choice Questions (MCQs)
with Answers and Explanations for
Professional Certification Exams
1. A patient admitted with acute decompensated heart failure develops worsening dyspnea,
bilateral crackles, and an oxygen saturation of 88% despite supplemental oxygen. Which
intervention should the nurse anticipate as the highest priority?
A. Initiation of enteral nutrition
B. Administration of broad-spectrum antibiotics
C. Initiation of noninvasive positive-pressure ventilation and intravenous diuretics
D. Immediate insertion of a permanent pacemaker
Explanation: Acute pulmonary edema secondary to heart failure requires rapid improvement in
oxygenation and reduction of preload through noninvasive ventilation and diuretic therapy.
2. A patient with sepsis has a lactate level of 5.2 mmol/L and persistent hypotension after
receiving 30 mL/kg of crystalloid fluids. Which medication should the nurse anticipate
administering next?
A. Dobutamine
B. Adenosine
C. Amiodarone
D. Norepinephrine
Explanation: Persistent hypotension despite adequate fluid resuscitation indicates septic shock.
Norepinephrine is the preferred first-line vasopressor to restore tissue perfusion.
3. A patient with atrial fibrillation suddenly develops slurred speech and right-sided
weakness. Which nursing action is the priority?
A. Administer subcutaneous insulin
B. Obtain a routine electrocardiogram
, C. Encourage oral fluid intake
D. Activate the stroke response protocol immediately
Explanation: Sudden neurological deficits suggest an acute ischemic stroke. Rapid activation of
stroke protocols facilitates timely reperfusion therapy.
4. A patient receiving heparin infusion develops hematuria and a platelet count of
85,000/mm³. Which complication should the nurse suspect?
A. Disseminated intravascular coagulation
B. Polycythemia
C. Vitamin K deficiency
D. Heparin-induced thrombocytopenia
Explanation: Thrombocytopenia associated with bleeding in a patient receiving heparin raises
concern for heparin-induced thrombocytopenia, which requires immediate discontinuation of
heparin.
5. A patient with chronic obstructive pulmonary disease develops increasing somnolence
and arterial blood gas values showing pH 7.28 and PaCO₂ 62 mmHg. Which acid-base
disturbance is present?
A. Metabolic alkalosis
B. Respiratory alkalosis
C. Mixed metabolic acidosis
D. Respiratory acidosis
Explanation: Elevated PaCO₂ with acidemia indicates respiratory acidosis caused by
inadequate alveolar ventilation.
6. A patient with acute coronary syndrome reports persistent chest pain despite nitroglycerin
therapy. Which biomarker is most specific for myocardial injury?
A. Creatine kinase
B. Myoglobin
C. Lactate dehydrogenase
