INTRODUCTION
This comprehensive NR571 Final Exam practice set focuses on complex
diagnosis and management encountered in advanced acute-care practice. The
questions emphasize synthesis of history, physical examination, laboratory data,
diagnostic imaging, pathophysiology, pharmacology, risk stratification, and
evidence-based treatment decisions. Students should expect clinically realistic
scenarios requiring prioritization, differential diagnosis, interpretation of
diagnostic findings, recognition of deterioration, medication selection, and
determination of appropriate disposition. The difficulty is intentionally
advanced and reflects graduate-level clinical reasoning rather than simple
factual recall. Particular emphasis is placed on unstable patients, competing
diagnoses, treatment complications, diagnostic uncertainty, antimicrobial
stewardship, hemodynamic management, and situations in which timely clinical
judgment directly affects patient outcomes.
,2 NR 571- COMPLEX DIAGNOSIS & MANAGEMENT IN ACUTE CARE PRACTICUM
QUESTIONS 1–150
Question 1
A 68-year-old patient presents with acute dyspnea, hypotension, jugular venous
distention, and clear bilateral lung fields. ECG demonstrates sinus tachycardia
with nonspecific ST-T changes. Bedside ultrasound shows a markedly dilated
right ventricle with reduced systolic function. Which diagnosis should be
prioritized?
A. Acute left ventricular failure
B. Massive pulmonary embolism with obstructive shock
C. Cardiac tamponade
D. Acute aortic regurgitation
Correct Answer: B
Explanation: Acute right ventricular dilation and dysfunction with
hypotension and clear lungs strongly support massive pulmonary embolism
causing obstructive shock.
Question 2
A patient with septic shock remains hypotensive after appropriate crystalloid
administration. MAP is 57 mmHg. Which intervention is most appropriate?
A. Begin norepinephrine
B. Administer IV furosemide
C. Begin propranolol
D. Administer sodium bicarbonate routinely
Correct Answer: A
Explanation: Norepinephrine is the preferred first-line vasopressor for
persistent hypotension after adequate initial fluid resuscitation in septic
shock.
Question 3
A patient with chest pain has a nondiagnostic initial ECG and an initial high-
sensitivity troponin below the assay's diagnostic threshold. Which approach is
most appropriate?
,3 NR 571- COMPLEX DIAGNOSIS & MANAGEMENT IN ACUTE CARE PRACTICUM
A. Discharge immediately based solely on the first troponin
B. Repeat serial troponin assessment using the validated assay algorithm
C. Diagnose unstable angina without further testing
D. Administer thrombolysis immediately
Correct Answer: B
Explanation: A single negative early troponin cannot reliably exclude acute
myocardial injury; serial testing according to the assay-specific pathway is
required.
Question 4
A patient develops sudden aphasia and right-sided weakness 45 minutes before
arrival. Glucose is normal, and noncontrast CT shows no hemorrhage. Which
consideration is most important next?
A. Delay treatment until MRI confirms infarction
B. Determine eligibility for reperfusion therapy based on clinical and imaging
criteria
C. Administer aspirin and discharge
D. Start warfarin immediately
Correct Answer: B
Explanation: Acute disabling ischemic stroke within the treatment window
requires rapid assessment for reperfusion eligibility after hemorrhage is
excluded.
Question 5
A patient with severe asthma has worsening dyspnea despite repeated
bronchodilators. The patient becomes increasingly fatigued and develops a
rising PaCO₂. What does this change most strongly indicate?
A. Improving ventilation
B. Impending respiratory failure
C. Isolated metabolic alkalosis
D. Resolution of bronchospasm
Correct Answer: B
, 4 NR 571- COMPLEX DIAGNOSIS & MANAGEMENT IN ACUTE CARE PRACTICUM
Explanation: Rising PaCO₂ in severe asthma reflects declining alveolar
ventilation and respiratory muscle fatigue, signaling impending respiratory
failure.
Question 6
A patient with pneumonia has BP 82/48 mmHg, lactate 4.5 mmol/L, altered
mentation, and cool extremities. Which physiologic state is most likely?
A. Cardiogenic shock
B. Distributive shock with tissue hypoperfusion
C. Stable compensated sepsis
D. Isolated hypovolemia without organ dysfunction
Correct Answer: B
Explanation: Infection accompanied by hypotension, elevated lactate, altered
mentation, and poor perfusion indicates severe distributive shock physiology.
Question 7
A patient with severe hyponatremia develops a generalized seizure. Which
intervention is the priority?
A. Rapid administration of hypotonic fluid
B. Controlled administration of hypertonic saline
C. Fluid restriction alone
D. Oral potassium supplementation
Correct Answer: B
Explanation: Severe symptomatic hyponatremia with seizures requires
carefully controlled hypertonic saline to rapidly reduce cerebral edema while
avoiding excessive correction.
Question 8
A patient with chronic kidney disease develops potassium of 7.1 mEq/L and
peaked T waves. Which medication should be administered immediately to
stabilize the myocardium?
A. IV calcium
B. Sodium polystyrene sulfonate alone
