APEA 3P Comprehensive Exam Review
2026/2027 – Complete Exam-Style Questions
with Correct Answers & Detailed Rationales |
Verified & Reliable
1.
A 68-year-old patient presents with progressive exertional
dyspnea, orthopnea, and bilateral ankle edema. Examination
reveals an S3 gallop, elevated jugular venous pressure, and
bibasilar crackles. Which pathophysiologic mechanism best
explains the patient's pulmonary congestion?
A. Decreased pulmonary vascular resistance
B. Increased left ventricular preload caused by reduced venous
return
C. Increased pulmonary capillary hydrostatic pressure
D. Increased plasma oncotic pressure
Correct answer: C. Increased pulmonary capillary hydrostatic
pressure
The patient's findings are characteristic of left-sided heart
failure. Reduced left ventricular pumping ability increases left
atrial and pulmonary venous pressures, which subsequently
,raise pulmonary capillary hydrostatic pressure. Fluid moves
from the intravascular space into the pulmonary interstitium
and alveoli, producing crackles, dyspnea, and orthopnea.
Decreased pulmonary vascular resistance and increased plasma
oncotic pressure would oppose pulmonary edema rather than
promote it.
2.
A 54-year-old patient has a blood pressure of 136/84 mm Hg on
repeated standardized measurements. According to the 2025
ACC/AHA hypertension guideline, this blood pressure falls into
which category?
A. Normal
B. Elevated
C. Stage 1 hypertension
D. Stage 2 hypertension
Correct answer: C. Stage 1 hypertension
Stage 1 hypertension is defined as a systolic blood pressure of
130–139 mm Hg or a diastolic pressure of 80–89 mm Hg. This
patient's systolic pressure is 136 mm Hg and diastolic pressure
is 84 mm Hg, placing the reading in stage 1 hypertension. The
current guideline emphasizes accurate repeated measurements
,and individualized cardiovascular-risk assessment when
determining treatment.
3.
A patient taking lisinopril develops facial swelling, lip edema,
and difficulty swallowing. Which mechanism most directly
explains this adverse reaction?
A. Histamine-mediated mast-cell degranulation
B. Bradykinin accumulation
C. Excess aldosterone production
D. Increased prostaglandin synthesis
Correct answer: B. Bradykinin accumulation
ACE inhibitors decrease degradation of bradykinin.
Accumulation of bradykinin can produce angioedema involving
the lips, tongue, face, and upper airway. This reaction can occur
even after prolonged therapy. Histamine-mediated allergy is
not the primary mechanism of ACE-inhibitor angioedema.
4.
A 29-year-old woman reports fatigue, cold intolerance,
constipation, dry skin, and weight gain. Laboratory testing
, shows elevated TSH and decreased free T4. Which physical
examination finding is most consistent with this disorder?
A. Fine tremor
B. Hyperreflexia
C. Delayed relaxation of deep tendon reflexes
D. Warm, moist skin
Correct answer: C. Delayed relaxation of deep tendon reflexes
Primary hypothyroidism causes decreased metabolic activity
and characteristic neuromuscular findings, including delayed
relaxation of deep tendon reflexes. Fine tremor, hyperreflexia,
and warm moist skin are more consistent with hyperthyroidism.
5.
A patient with type 2 diabetes has an A1C of 7.1% on two
separate measurements. The patient has no symptoms of
hyperglycemia. Which interpretation is most appropriate?
A. Diabetes cannot be diagnosed without an abnormal fasting
glucose
B. The diagnosis is confirmed by the repeated abnormal A1C
C. A random glucose level must exceed 200 mg/dL
D. An oral glucose tolerance test is mandatory
