APEA PRE-PREDICTOR 2026
SECTION 1: ADVANCED HEALTH ASSESSMENT & DIAGNOSTIC REASONING (Questions 1–25)
1. A 58-year-old male with type 2 diabetes reports burning foot pain that is worse at night.
Which of the following is the most likely diagnosis based on his presentation?
A. Peripheral artery disease
B. Lumbar radiculopathy
C. Diabetic peripheral neuropathy
D. Morton's neuroma
Rationale: Diabetic peripheral neuropathy typically presents with burning, tingling, or
numbness in the feet that worsens at night. It is a common complication of long-standing
diabetes and is the most likely diagnosis given the patient's history.
2. A 45-year-old woman presents with a blood pressure reading of 152/96 mmHg on two
separate visits. According to JNC 8 guidelines, which of the following is the most appropriate
initial pharmacological intervention?
A. Start lisinopril 10 mg daily
B. Start amlodipine 5 mg daily
C. Start hydrochlorothiazide 25 mg daily
D. Start metoprolol 50 mg twice daily
1|Page
,Page 2 of 77
Rationale: According to JNC 8 guidelines, for non-Black patients without comorbidities, an ACE
inhibitor like lisinopril is an appropriate first-line agent. For Black patients, a thiazide or calcium
channel blocker is preferred.
3. A 68-year-old male presents with a deep, nonblanching rash on the flexor surfaces of the
skin associated with fever and pharyngitis. Which of the following is the most likely
diagnosis?
A. Scarlet fever
B. Measles
C. Rubella
D. Toxic shock syndrome
Rationale: A deep, nonblanching rash on the flexor surfaces associated with fever, pharyngitis,
and cervical lymphadenopathy is characteristic of scarlet fever, which is caused by Group A
Beta-hemolytic streptococcus.
4. A 32-year-old female presents with a classic diagnostic physical finding associated with a
chronic presentation of atopic dermatitis. Which of the following is the most likely finding?
A. Lichenification
B. Vesicular lesions
C. Honey-colored crusts
D. Annular scaly plaques
Rationale: Chronic atopic dermatitis is characterized by lichenification (thickening and leathery
texture of the skin) due to prolonged scratching and rubbing.
5. A 24-year-old female presents with dysuria, frequency, and urgency. Which pathogen is the
most common cause of uncomplicated urinary tract infections in outpatient female patients?
A. Staphylococcus saprophyticus
B. Escherichia coli
C. Klebsiella pneumoniae
D. Proteus mirabilis
2|Page
,Page 3 of 77
Rationale: Escherichia coli is the most common pathogen responsible for uncomplicated urinary
tract infections in outpatient female patients, accounting for approximately 75–95% of cases.
6. A 72-year-old male presents with a new onset of unilateral, sharp, lancinating pain in the
distribution of the ophthalmic branch of the trigeminal nerve, accompanied by a vesicular
rash on the forehead and nose. Which of the following is the most likely diagnosis?
A. Herpes zoster ophthalmicus
B. Trigeminal neuralgia
C. Acute angle-closure glaucoma
D. Cellulitis
Rationale: Herpes zoster ophthalmicus presents with unilateral pain and vesicular rash in the
distribution of the ophthalmic branch of the trigeminal nerve. It requires prompt antiviral
therapy to prevent ocular complications.
7. A 55-year-old female presents with a sudden onset of severe, throbbing headache
associated with nausea, photophobia, and phonophobia. Which of the following is the most
likely diagnosis?
A. Tension headache
B. Migraine headache
C. Cluster headache
D. Sinus headache
Rationale: Migraine headaches are characterized by severe, throbbing pain, often unilateral,
accompanied by nausea, photophobia, and phonophobia. They may be preceded by an aura.
8. A 62-year-old male with a history of smoking presents with a chronic cough and progressive
dyspnea on exertion. Which of the following findings on physical examination would be most
consistent with a diagnosis of COPD?
A. Increased tactile fremitus
B. Barrel-shaped chest
C. Dullness to percussion
D. Egophony
3|Page
, Page 4 of 77
Rationale: A barrel-shaped chest is a classic physical examination finding in patients with COPD,
resulting from hyperinflation of the lungs and increased anteroposterior diameter.
9. A 40-year-old female presents with fatigue, weight gain, cold intolerance, and constipation.
Which of the following laboratory findings would be most consistent with a diagnosis of
hypothyroidism?
A. Elevated TSH, low free T4
B. Low TSH, elevated free T4
C. Elevated TSH, elevated free T4
D. Low TSH, low free T4
Rationale: Primary hypothyroidism is characterized by an elevated TSH and a low free T4,
reflecting the pituitary's attempt to stimulate a failing thyroid gland.
10. A 28-year-old male presents with a painless, firm, solitary nodule on the shaft of the
penis. Which of the following is the most likely diagnosis?
A. Peyronie's disease
B. Condyloma acuminatum
C. Primary syphilis
D. Lichen planus
Rationale: Peyronie's disease is characterized by a painless, firm nodule or plaque on the shaft
of the penis, often associated with penile curvature during erection.
11. A 75-year-old female presents with sudden onset of painless, unilateral vision loss in the
right eye. Which of the following is the most likely diagnosis?
A. Cataract
B. Open-angle glaucoma
C. Central retinal artery occlusion
D. Macular degeneration
Rationale: Central retinal artery occlusion presents with sudden, painless, unilateral vision loss.
It is an ophthalmologic emergency requiring immediate intervention.
