APEA 3P Exam Predictor | Most Frequently Tested Questions,
Correct Answers & Step-by-Step Rationales
QUESTION 1
A patient with chronic heart failure presents with worsening dyspnea
and elevated brain natriuretic peptide levels. The nurse practitioner
knows that brain natriuretic peptide is released primarily by:
A. Renal tubular cells in response to hypoxia
B. Ventricular myocardial cells in response to wall stretch and volume
overload
C. Endothelial cells lining the systemic arterial vasculature
D. The posterior pituitary gland during fluid deficits
Correct Answer: B Ventricular myocardial cells in response to wall
stretch and volume overload
Rationale: Brain natriuretic peptide is a hormone secreted by
ventricular cardiomyocytes in response to increased wall stress and
stretch, serving as a marker for heart failure.
QUESTION 2
A patient initiated on lisinopril for hypertension reports a persistent,
dry, hacking cough. This adverse drug reaction is primarily attributed to
the accumulation of which substance in the lungs?
A. Histamine
,B. Bradykinin
C. Acetylcholine
D. Serotonin
Correct Answer: B Bradykinin
Rationale: Angiotensin-converting enzyme inhibitors prevent the
breakdown of bradykinin and substance P, leading to their pulmonary
accumulation and the characteristic dry cough.
QUESTION 3
During an abdominal physical examination, the nurse practitioner
percusses the liver span along the right midclavicular line. The normal
vertical span of the liver in an adult is typically:
A. 2 to 4 centimeters
B. 6 to 12 centimeters
C. 15 to 20 centimeters
D. 22 to 25 centimeters
Correct Answer: B 6 to 12 centimeters
Rationale: Normal adult liver span measured by percussion along the
right midclavicular line typically ranges between 6 and 12 centimeters.
QUESTION 4
,The underlying pathophysiology of an acute asthma attack involves
bronchial hyperresponsiveness and airflow obstruction driven primarily
by which immune cells?
A. Neutrophils and CD8+ T-lymphocytes
B. Eosinophils, mast cells, and IgE-mediated inflammation
C. Plasma cells producing pathogenic autoantibodies
D. Macrophages releasing destructive matrix metalloproteinases
Correct Answer: B Eosinophils, mast cells, and IgE-mediated
inflammation
Rationale: Asthma is characterized by type 1 hypersensitivity reactions
where allergen-specific IgE activates mast cells and recruits eosinophils,
causing bronchoconstriction and inflammation.
QUESTION 5
When prescribing a beta-blocker for a patient with diabetes mellitus,
the clinician must counsel the patient regarding the risk of masking
symptoms of:
A. Hyperglycemia
B. Hypoglycemia
C. Diabetic ketoacidosis
D. Hyperosmolar hyperglycemic state
Correct Answer: B Hypoglycemia
, Rationale: Beta-blockers can mask early sympathetic warning signs of
hypoglycemia, such as tachycardia, tremors, and palpitations, though
diaphoresis usually remains unmasked.
QUESTION 6
To evaluate the motor strength of the trapezius muscle during a cranial
nerve examination, the nurse practitioner instructs the patient to:
A. Shoulder shrug against applied resistance
B. Turn the head against lateral resistance
C. Stick out the tongue and move it side to side
D. Smile and puff out the cheeks
Correct Answer: A Shoulder shrug against applied resistance
Rationale: Cranial Nerve XI (accessory nerve) innervates the
sternocleidomastoid and trapezius muscles, tested by evaluating
shoulder shrug strength against resistance.
QUESTION 7
The vast majority of peptic ulcer disease cases are caused by chronic
infection with Helicobacter pylori or the chronic use of:
A. Acetaminophen
B. Nonsteroidal anti-inflammatory drugs
C. Selective serotonin reuptake inhibitors
D. Statins
