APEA 3P Nurse Practitioner Exam Review
2026/2027 – Complete Exam-Style Questions
with Correct Answers & Detailed Rationales |
Verified & Reliable
1.
A 68-year-old patient presents with exertional dyspnea,
orthopnea, and bilateral ankle edema. Examination reveals an
S3 gallop and bibasilar crackles. Which pathophysiologic
mechanism best explains the development of pulmonary
congestion?
A. Increased pulmonary vascular resistance caused by hypoxic
vasoconstriction
B. Reduced plasma oncotic pressure from hepatic dysfunction
C. Increased pulmonary capillary hydrostatic pressure from
left ventricular dysfunction
D. Increased lymphatic drainage caused by elevated right-sided
pressure
Rationale: Left ventricular systolic or diastolic dysfunction
elevates left atrial and pulmonary venous pressures. The
resulting increase in pulmonary capillary hydrostatic pressure
drives fluid into the pulmonary interstitium and, when
,sufficiently severe, the alveoli, producing crackles, dyspnea,
and orthopnea. Reduced oncotic pressure can cause edema
but does not best explain the classic heart-failure pattern with
an S3 and pulmonary congestion.
2.
A patient with hypertension is started on lisinopril. Which
laboratory abnormality is most important to monitor after
initiation and dose increases?
A. Decreased serum sodium
B. Increased serum chloride
C. Decreased serum calcium
D. Increased serum potassium
Rationale: ACE inhibitors reduce angiotensin II production,
decreasing aldosterone secretion and therefore reducing renal
potassium excretion. Hyperkalemia is particularly important in
patients with chronic kidney disease, diabetes, or concomitant
potassium-raising medications. Renal function should also be
monitored because creatinine may rise after initiation.
3.
A 24-year-old patient reports episodic palpitations and
tremulousness. Examination reveals a fine tremor, warm moist
skin, and a diffusely enlarged thyroid. Which laboratory pattern
is most consistent with primary hyperthyroidism?
,A. Increased TSH and decreased free T4
B. Increased TSH and increased free T4
C. Decreased TSH and increased free T4
D. Decreased TSH and decreased free T4
Rationale: In primary hyperthyroidism, excessive thyroid
hormone production suppresses pituitary TSH secretion
through negative feedback. Thus, free T4 is elevated while TSH
is typically suppressed. Graves disease is a common cause and
may produce diffuse goiter and other manifestations of
thyroid hormone excess.
4.
A patient with asthma uses an inhaled corticosteroid daily.
Which instruction is most appropriate?
A. Use the medication only during an acute asthma attack
B. Stop the medication once symptoms improve for 48 hours
C. Rinse the mouth after each use
D. Use the medication immediately before every exercise
session as the sole preventive therapy
Rationale: Inhaled corticosteroids are controller medications
used regularly to reduce airway inflammation and
exacerbation risk. Oropharyngeal candidiasis and dysphonia
can occur because medication deposits in the mouth and
pharynx; rinsing and spitting after administration reduces this
, risk. They are not intended to provide rapid relief during acute
bronchospasm.
5.
A 72-year-old patient taking warfarin for atrial fibrillation
develops melena. The INR is 7.1, but the patient is
hemodynamically stable. Which intervention is most
appropriate?
A. Administer aspirin
B. Continue warfarin and recheck the INR in one week
C. Hold warfarin and administer vitamin K according to the
severity of bleeding
D. Replace warfarin immediately with clopidogrel
Rationale: Clinically significant bleeding in a patient with
excessive anticoagulation requires immediate interruption of
warfarin and reversal based on bleeding severity. Vitamin K
restores hepatic synthesis of vitamin-K-dependent clotting
factors, while severe or life-threatening bleeding may
additionally require a four-factor prothrombin complex
concentrate.
6.
A 35-year-old patient presents with acute unilateral calf
swelling, warmth, and tenderness after a long-haul flight.
Which finding most strongly supports deep venous thrombosis?
