NR 601 Primary Care of the
Maturing and Aged Family Midterm
Exam Study Guide, Practice
Questions, and Test Bank Review
2026/2027
Question 1:
The percentage of forced vital capacity (FVC) exhaled in one second is best
represented by which parameter?
A. Total lung capacity (TLC)
B. FEV1/FVC ratio
C. Peak expiratory flow rate
D. Residual volume
Correct Answer: B. FEV1/FVC ratio
Rationale: The FEV1/FVC ratio measures the proportion of total forced vital capacity
exhaled during the first second of expiration. It is a key diagnostic indicator used to
differentiate obstructive from restrictive lung disease. Option A refers to total lung
capacity, which is the maximum lung volume. Option C measures the highest speed
of expiration, not a ratio. Option D represents air remaining after maximal exhalation
and is unrelated to this measurement.
Question 2:
Which structural cardiac change is commonly associated with normal aging?
A. Thinning of cardiac valves
B. Increased myocardial elasticity
C. Valve thickening and rigidity due to fibrosis
D. Decreased ventricular wall thickness
Correct Answer: C. Valve thickening and rigidity due to fibrosis
Rationale: Aging commonly leads to fibrotic changes in cardiac structures, resulting
in thickened and stiffened valves. This contributes to murmurs and reduced cardiac
efficiency. Option A is incorrect because valves do not thin with age. Option B is
incorrect as elasticity decreases. Option D is incorrect because ventricular walls often
become thicker, not thinner.

Question 3:
A patient develops a chronic dry cough after starting antihypertensive therapy. Which
medication is most likely responsible?
A. Amlodipine
B. Hydrochlorothiazide
C. Lisinopril
D. Metoprolol
Correct Answer: C. Lisinopril
Rationale: Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough due
to increased bradykinin levels. Amlodipine causes edema, hydrochlorothiazide causes
electrolyte changes, and metoprolol may cause bradycardia but not cough.
Question 4:
A patient with structural heart disease and current heart failure symptoms is classified
as which ACC/AHA stage?
A. Stage A
B. Stage B
C. Stage C
D. Stage D
Correct Answer: C. Stage C
Rationale: Stage C heart failure includes structural heart disease with current or prior
symptoms of heart failure. Stage A includes risk factors only, Stage B includes
structural disease without symptoms, and Stage D is advanced refractory heart failure.
Question 5:
Which diagnostic tool is the best noninvasive method for evaluating structural heart
disease?
A. Electrocardiogram
B. Chest X-ray
C. Echocardiogram
D. Cardiac enzymes
Correct Answer: C. Echocardiogram
Rationale: Echocardiography provides direct visualization of cardiac structure and
function. ECG shows electrical activity but not structural abnormalities. Chest X-ray
provides indirect evidence. Cardiac enzymes assess myocardial injury.

Question 6:
The primary pathophysiological mechanism of heart failure is:
A. Increased oxygen delivery to tissues
B. Inadequate cardiac output to meet metabolic demands
C. Increased vascular resistance only
D. Excessive cardiac electrical activity
Correct Answer: B. Inadequate cardiac output to meet metabolic demands
Rationale: Heart failure occurs when the heart cannot pump sufficient blood to meet
the body's metabolic and oxygen demands. The other options do not represent the
core mechanism of heart failure.
Question 7:
Which pulmonary function test represents the total volume of air exhaled during a
forced expiratory maneuver?
A. FEV1
B. FVC
C. TLC
D. RV
Correct Answer: B. FVC
Rationale: Forced vital capacity (FVC) measures total air exhaled after maximal
inhalation. FEV1 measures first-second exhalation. TLC is total lung capacity. RV is
residual volume.
Question 8:
According to ACC/AHA guidelines, normal blood pressure is defined as:
A. <130/80 mmHg
B. <140/90 mmHg
C. <120/80 mmHg
D. <110/70 mmHg
Correct Answer: C. <120/80 mmHg
Rationale: Normal blood pressure is defined as systolic <120 and diastolic <80 mmHg.
Higher thresholds represent elevated or hypertensive states.
Question 9:
, 2026/2027
Which finding should be assessed in a patient with chronic uncontrolled hypertension
to evaluate target organ damage?
A. Retinal hemorrhage
B. Left ventricular hypertrophy
C. Liver enlargement
D. Splenomegaly
Correct Answer: B. Left ventricular hypertrophy
Rationale: Chronic hypertension causes pressure overload leading to LV hypertrophy,
a major marker of target organ damage. Retinal changes may also occur but LVH is a
key cardiac manifestation.
Question 10:
Which medication is indicated for early heart failure symptoms in aortic regurgitation?
A. Beta blockers
B. ACE inhibitors
C. Calcium channel blockers
D. Diuretics only
Correct Answer: B. ACE inhibitors
Rationale: ACE inhibitors reduce afterload and improve forward flow in aortic
regurgitation. Beta blockers may worsen regurgitation. Diuretics provide symptom
relief but do not modify disease progression.
Question 11:
Which lung volume represents maximal lung inflation?
A. FVC
B. RV
C. TLC
D. FEV1
Correct Answer: C. TLC
Rationale: Total lung capacity (TLC) is the maximum amount of air the lungs can
hold. Other options measure partial volumes or flow rates.
Question 12:
Which exercise recommendation is most appropriate for older adults?
