Introduction
This comprehensive question bank contains 300 multiple-choice
questions designed to prepare you for the NRNP 6550 Midterm Examination. The
questions cover all major content areas including cardiopulmonary disorders,
diagnostics, geriatric considerations, neurological and psychiatric conditions,
infectious diseases, and advanced practice nursing management of acutely and
critically ill adult patients. Each question includes four answer choices (A, B, C, D)
with the correct answer indicated and a detailed rationale provided for educational
purposes. Questions are randomized and non-duplicative to ensure thorough
content review.
SECTION 1: CARDIOPULMONARY DISORDERS (Questions 1-50)
1. A 68-year-old male presents with dyspnea, orthopnea, and peripheral
edema. Chest X-ray reveals bilateral pleural effusions. Thoracentesis is
performed. Which finding would be MOST consistent with a transudative
effusion?
• A) Protein ratio (pleural/serum) > 0.5
• B) LDH ratio (pleural/serum) > 0.6
• C) Pleural fluid LDH > 200 IU/L
• D) Protein ratio (pleural/serum) < 0.5
,Correct Answer: D
Rationale: Transudative effusions are characterized by a protein ratio
(pleural/serum) of < 0.5, LDH ratio < 0.6, and pleural fluid LDH < 200 IU/L.
These findings indicate a low-protein fluid typically caused by increased
hydrostatic pressure (CHF) or decreased oncotic pressure (cirrhosis, nephrotic
syndrome). Options A, B, and C are characteristic of exudative effusions seen in
inflammatory or malignant conditions.
2. A 72-year-old female with known coronary artery disease arrives at the
emergency department with crushing substernal chest pain radiating to her
left arm. She is diaphoretic and nauseated. Which is the CORRECT initial
medication protocol for suspected acute coronary syndrome?
• A) Aspirin 81mg PO, nitroglycerin 0.2mg SL, morphine 2mg IV, and oxygen
at 2L/min
• B) Aspirin 162-325mg PO, nitroglycerin 0.4mg SL q5min, oxygen at 2-
4L/min, and morphine 2-4mg IV
• C) Aspirin 325mg PR, nitroglycerin 0.6mg SL, oxygen at 6L/min, and
fentanyl 50mcg IV
• D) Aspirin 81mg PO, nitroglycerin patch 0.4mg/hr, oxygen at 4L/min, and
ketorolac 30mg IV
Correct Answer: B
Rationale: The emergency protocol for ACS includes aspirin 162-325mg PO
(chewed), nitroglycerin 0.4mg sublingual every 5 minutes for up to 3 doses,
oxygen at 2-4L/min to maintain SpO2 > 90%, and morphine 2-4mg IV for pain
unrelieved by nitroglycerin. Option A uses incorrect aspirin and morphine dosing.
Option C has excessive oxygen and incorrect nitroglycerin dosing. Option D does
not include the standard emergency protocol medications.
3. A patient with suspected myocardial infarction has cardiac enzymes drawn.
Which biomarker typically becomes elevated FIRST after symptom onset?
, • A) Troponin I
• B) Troponin T
• C) Creatine kinase-MB (CK-MB)
• D) Myoglobin
Correct Answer: D
Rationale: Myoglobin rises within 2-3 hours of symptom onset and peaks at 6-12
hours. It is the earliest marker of myocardial injury but lacks cardiac specificity.
Troponin increases after 4-6 hours but is highly specific. CK-MB rises after 4-8
hours and peaks at 12-24 hours. Option A and B (troponins) are more specific but
appear later than myoglobin.
4. A 55-year-old male is enrolled in a cardiac rehabilitation program following
an uncomplicated MI. He is in Phase 2 of cardiac rehabilitation. Which
activity would be MOST appropriate for this phase?
• A) Bed rest with passive range of motion exercises
• B) Medically supervised reconditioning with monitored exercise sessions
• C) Unsupervised community-based exercise program
• D) High-intensity interval training at maximum heart rate
Correct Answer: B
Rationale: Phase 2 of cardiac rehabilitation is an outpatient, medically supervised
program lasting 8-12 weeks that includes reconditioning with monitored exercise
sessions, education, and risk factor modification. Phase 1 is hospital-based. Phase 3
is long-term maintenance. Option A describes acute phase activities, and Option D
would be too intense for Phase 2.
5. A 65-year-old patient with a history of MI is now on a cardiac rehabilitation
program. Which long-term goal is MOST appropriate for Phase 3
maintenance?
, • A) Complete bed rest and restricted activity
• B) Unsupervised community-based exercise with periodic follow-up
• C) Hospital-based intensive monitoring
• D) Surgical intervention planning
Correct Answer: B
Rationale: Phase 3 is the long-term maintenance phase that emphasizes
unsupervised community-based exercise with periodic follow-up, lifestyle
modification, and risk factor management. This phase focuses on sustaining the
gains achieved in Phase 2 with less intensive supervision.
6. A 60-year-old male with a history of hypertension presents with sudden
onset of severe, tearing chest pain radiating to the back. Blood pressure is
190/100 mmHg in the right arm and 140/80 mmHg in the left arm. Which
diagnostic test is the test of choice?
• A) Chest X-ray
• B) CT scan with contrast
• C) Transthoracic echocardiogram
• D) MRI without contrast
Correct Answer: B
Rationale: CT scan with contrast (CT angiography) is the test of choice for
confirming suspected ascending aortic aneurysm or aortic dissection. It provides
detailed visualization of the aortic wall and can identify intimal flaps. Chest X-ray
may show widened mediastinum but is not definitive. MRI is time-consuming and
less accessible, while echocardiogram may miss thoracic extension.
7. According to ATP III guidelines, which LDL cholesterol level is considered
OPTIMAL?
• A) < 130 mg/dL
