APEA Predictor Exam Questions and
Correct Answers with Rationales – High-
Yield Q&A
1. A 32-year-old female arrives at the clinic reporting abrupt onset of right lower quadrant pain
accompanied by nausea and a mild fever. On physical examination, rebound tenderness is
elicited. What is the most probable diagnosis?
A) Ruptured ovarian cyst
B) Acute appendicitis
C) Ectopic pregnancy
D) Pelvic inflammatory disease
Correct Answer: B) Acute appendicitis
Rationale: The hallmark presentation of right lower quadrant pain with rebound tenderness,
combined with systemic features such as nausea and low-grade fever, strongly supports
appendicitis. While the other diagnoses can present with overlapping symptoms, the
anatomical location and clinical signs are most consistent with appendicitis.
2. A 10-year-old child presents with fever, a sore throat, and a sandpaper-textured rash
spreading across the trunk. Which pathogen is responsible?
A) Staphylococcus aureus
B) Group A Streptococcus
C) Haemophilus influenzae
D) Epstein-Barr virus
Correct Answer: B) Group A Streptococcus
, Rationale: This clinical picture is classic for scarlet fever, which results from Group A
Streptococcus infection. Typical findings include pharyngitis, fever, and a characteristic fine,
erythematous rash.
3. A 58-year-old male with type 2 diabetes reports increased urination, excessive thirst, and
blurred vision. His HbA1c is 9.5%. What is the appropriate next step?
A) Monitor and repeat labs in 3 months
B) Intensify glycemic management with lifestyle changes and medications
C) Initiate antibiotics
D) Order a cardiac stress test
Correct Answer: B) Intensify glycemic management with lifestyle changes and medications
Rationale: An HbA1c exceeding 9% reflects suboptimal glycemic control, warranting immediate
intensification of treatment.
4. A 25-year-old woman who delivered 2 weeks ago presents with sudden-onset shortness of
breath and pleuritic chest pain. What is the most pressing concern?
A) Asthma exacerbation
B) Pulmonary embolism
C) Pneumonia
D) Myocardial infarction
Correct Answer: B) Pulmonary embolism
Rationale: The hypercoagulable state of the postpartum period, paired with abrupt dyspnea,
places this patient at significant risk for pulmonary embolism.
5. A 6-year-old presents with fever, productive cough, coarse crackles on auscultation, and a
WBC count of 15,000/mm³. Which antibiotic is appropriate for empiric treatment of
community-acquired pneumonia?
A) Azithromycin
B) Amoxicillin
C) Ciprofloxacin
D) Trimethoprim-sulfamethoxazole
