Introduction
,The NR 574 Acute Care Practicum I final examination assesses the
advanced clinical reasoning and management skills required for
acute care nurse practitioner practice. This assessment evaluates
synthesis of pathophysiology, diagnostics, and evidence-based
interventions across critical care populations. The multiple-choice
and scenario-based structure emphasizes real-world decision-
making, prioritization, and integration of pharmacologic and non-
pharmacologic therapies in high-acuity environments. Candidates
must demonstrate readiness for independent practice through
application of standards of care, ethical principles, and
interprofessional collaboration.
SECTION ONE: QUESTIONS 1–100
Question 1
A patient presents with chest pain radiating to the left arm. What is
the first priority intervention?
A. Obtain a 12-lead ECG
B. Draw troponin levels
C. Administer supplemental oxygen
D. Start IV fluids
Correct answer: A
RATIONALE: A 12-lead ECG should be obtained within 10
minutes of presentation to identify ST-elevation myocardial
infarction (STEMI) and guide immediate reperfusion therapy.
Troponin, oxygen, and IV fluids follow initial ECG assessment .
,Question 2
Which biomarker is most sensitive and specific for myocardial
infarction?
A. CK-MB
B. Troponin
C. Myoglobin
D. BNP
Correct answer: B
RATIONALE: Troponin is highly specific and sensitive for
myocardial injury and remains elevated for 7–14 days, making it the
preferred biomarker for diagnosing acute myocardial infarction .
Question 3
What is the minimum acceptable urine output per hour in an adult
patient?
A. 10 mL
B. 20 mL
C. 30 mL
D. 50 mL
Correct answer: C
RATIONALE: Minimum acceptable urine output is 0.5
mL/kg/hr, which approximates 30 mL/hr for an average adult.
Output below this threshold suggests inadequate renal perfusion or
acute kidney injury .
Question 4
, A patient develops urticaria, wheezing, and hypotension after
receiving an antibiotic. What is the first-line treatment?
A. Diphenhydramine
B. Epinephrine
C. Corticosteroids
D. Supplemental oxygen
Correct answer: B
RATIONALE: Epinephrine is the first-line treatment for
anaphylaxis. It reverses airway swelling, bronchospasm, and
hypotension rapidly. Antihistamines and steroids are adjunctive
therapies, not initial interventions .
Question 5
What is the most common cause of hypoxemia in acute care
patients?
A. Anemia
B. Ventilation-perfusion (V/Q) mismatch
C. Hyperventilation
D. Hypertension
Correct answer: B
RATIONALE: Ventilation-perfusion mismatch is the most
common mechanism of hypoxemia in acute care settings, occurring
in conditions such as pneumonia, pulmonary edema, and acute
respiratory distress syndrome .
