NRNP 6531 EXAM 200 ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST 2026 ALREADY
GRADED A+
This comprehensive set of 200 unique multiple-choice questions is designed to
prepare you for the NRNP 6531 Primary Care of Adults Across the Lifespan
exam. The questions cover all major content areas including cardiology,
pulmonology, endocrinology, gastroenterology, neurology, rheumatology, and
pharmacology. Each question presents a clinical vignette requiring diagnostic
reasoning, treatment selection, or medication management. Detailed
rationales explain why the correct answer is right and why the distractors are
wrong, reinforcing key concepts. No question is repeated, ensuring thorough
coverage of the material. This resource is ideal for FNP students seeking to
test their knowledge and identify areas requiring further study.
1. A 58-year-old man with hypertension reports substernal chest pressure with
exertion, relieved by rest. What is the most appropriate next step?
A) Order a stress echocardiogram
B) Prescribe nitroglycerin PRN
C) Start high-intensity statin
D) Refer to ER for troponin
Answer: A
Rationale: This presentation is consistent with stable angina. Stress testing
(echocardiogram or nuclear) is indicated to assess for ischemia. Nitroglycerin
provides symptomatic relief but is not diagnostic. Statin therapy is indicated but
not the immediate next step. ER referral is for unstable angina.
2. Which ACE inhibitor side effect is most characteristic and requires monitoring
in a 72-year-old with CKD?
A) Dry cough
B) Angioedema
C) Hyperkalemia
D) Hypotension
Answer: C
,Rationale: In CKD, ACE inhibitors reduce aldosterone secretion, leading to
potassium retention and hyperkalemia. Dry cough is common but not unique to
CKD. Angioedema is rare. Hypotension can occur but is not the most characteristic
lab finding requiring monitoring.
3. A 45-year-old female has a blood pressure of 148/92 mmHg on two visits. No
diabetes or CKD. What is first-line monotherapy?
A) HCTZ
B) Lisinopril
C) Amlodipine
D) Metoprolol
Answer: B
Rationale: ACE inhibitors (lisinopril) are first-line for non-Black patients without
compelling indications. Thiazides are also acceptable but ACE inhibitors are
preferred in younger patients. CCB (amlodipine) is an alternative. Beta-blockers
are not first-line for hypertension without other indications.
4. ECG shows irregularly irregular rhythm with no P waves. Rate is 110-130 bpm.
What is the best initial pharmacotherapy for rate control?
A) Amiodarone
B) Metoprolol
C) Aspirin
D) Diltiazem IV
Answer: D
Rationale: Atrial fibrillation with rapid ventricular response. IV diltiazem
(nondihydropyridine CCB) is first-line for acute rate control. Metoprolol is also
used but diltiazem is often preferred in the acute setting. Amiodarone is for rhythm
control or unstable patients.
5. A 70-year-old has a blood pressure of 180/100 mmHg with no symptoms.
Repeat in office 5 minutes later is 178/98. What is the most appropriate next step?
A) Refer to emergency department
B) Start amlodipine 10 mg daily
C) Obtain home BP readings for 1 week
D) Sublingual nifedipine
Answer: C
Rationale: Asymptomatic severe hypertension (hypertensive urgency) does not
require emergency treatment. Home BP monitoring to rule out white coat
hypertension. Slow oral therapy if sustained. Sublingual nifedipine is dangerous
due to risk of uncontrolled hypotension and stroke.
,6. A 50-year-old with no cardiac history has a murmur: mid-systolic click followed
by late systolic murmur at apex. What is the diagnosis?
A) Aortic stenosis
B) Mitral regurgitation (chronic)
C) Mitral valve prolapse
D) Hypertrophic cardiomyopathy
Answer: C
Rationale: Mitral valve prolapse presents with a mid-systolic click (prolapse)
followed by a late systolic murmur (regurgitation). HCM has a systolic murmur at
the left lower sternal border. Aortic stenosis has a crescendo-decrescendo murmur
at the right upper sternal border. Chronic MR has a holosystolic murmur at the
apex.
7. A 75-year-old has an abdominal aortic aneurysm detected on ultrasound at 4.5
cm. What is the appropriate management?
A) Immediate surgical repair
B) Repeat ultrasound every 6-12 months
C) CT angiogram now and repair if >5.5 cm
D) Start doxycycline to reduce growth
Answer: B
Rationale: AAA 4.0-4.9 cm requires ultrasound surveillance every 6-12 months.
Surgical repair is typically recommended at 5.5 cm in men or 5.0 cm in women, or
with rapid growth (>0.5 cm in 6 months).
8. A 72-year-old reports syncope while walking. ECG shows heart rate 38 bpm,
regular, with P waves not associated with QRS complexes. What is the diagnosis?
A) Wenckebach (Mobitz I)
B) Complete heart block (Mobitz III)
C) Sinus bradycardia
D) Atrial fibrillation with slow response
Answer: B
Rationale: Third-degree AV block shows no relationship between P waves and
QRS complexes with a ventricular escape rhythm. Mobitz I has progressive PR
prolongation. Sinus bradycardia has 1:1 conduction. Atrial fibrillation has no P
waves.
9. Which beta-blocker is preferred in heart failure with reduced ejection fraction?
A) Metoprolol tartrate
B) Atenolol
, C) Carvedilol
D) Propranolol
Answer: C
Rationale: Carvedilol, metoprolol succinate (not tartrate), and bisoprolol have
mortality benefit in HFrEF. Metoprolol tartrate is short-acting and not proven.
Atenolol and propranolol are not indicated for HFrEF.
10. A 48-year-old obese female has dyspnea on exertion, orthopnea, and JVD.
Echo shows preserved EF (65%) and concentric LV hypertrophy. What is the most
likely diagnosis?
A) Constrictive pericarditis
B) Hypertrophic cardiomyopathy
C) HFpEF
D) Cardiac amyloidosis
Answer: C
Rationale: Heart failure with preserved ejection fraction (HFpEF) presents with
diastolic dysfunction. Common risk factors include obesity, hypertension, and
diabetes. Concentric LVH is typical. Constrictive pericarditis has a septal bounce.
HCM has asymmetric septal hypertrophy.
11. A 60-year-old with AF on apixaban presents with acute onset left leg pain,
pallor, and pulselessness. What is the next step?
A) Apixaban level
B) CT angiography of lower extremity
C) Emergent surgical consultation for embolectomy
D) Start heparin drip
Answer: C
Rationale: Acute limb ischemia from embolus requires immediate vascular surgery
evaluation for embolectomy or thrombolysis. Delay can lead to limb loss. CT
angiography can confirm but should not delay surgical consultation.
12. A 65-year-old with hypertension and CKD stage 3 has BP 150/90 on lisinopril
20 mg. Labs: K+ 5.1, Cr 1.4. What is the best addition?
A) HCTZ 12.5 mg
B) Amlodipine 5 mg
C) Spironolactone 12.5 mg
D) Increase lisinopril to 40 mg
Answer: B
