APEA Predictor Exam 2026 Comprehensive Practice
Examination WITH QUESTIONS AND WELL VERIFIED
ANSWERS
1. What headache sign does not warrant an immediate investigation?
A) Sudden onset of the worst headache of life
B) Headache relieved with use of common analgesics
C) New headache in a patient over 50 years old
D) Headache accompanied by neurological deficits
Correct ANSWER✔✨-: B) Headache relieved with use of common analgesics
Rationale:
Option A: Sudden onset "thunderclap" headache requires immediate investigation as it may
indicate subarachnoid hemorrhage, stroke, or other serious intracranial pathology. This is
considered a red flag symptom.
Option B (Correct): Headaches that respond well to common analgesics typically indicate
benign conditions such as tension headaches or mild migraines. This response pattern suggests
the absence of serious underlying pathology and does not require urgent investigation.
Option C: New headaches in patients over 50 years old warrant investigation due to increased
risk of giant cell arteritis, intracranial masses, or other age-related pathologies.
Option D: Headaches accompanied by neurological deficits require immediate evaluation as
they may indicate stroke, tumor, abscess, or increased intracranial pressure.
,2. During a migraine, what happens to the cerebral arteries?
A) They constrict
B) They dilate
C) They remain unchanged
D) They become inflamed
Correct ANSWER✔✨-: B) They dilate
Rationale:
Option A: Vasoconstriction is associated with the aura phase of migraine, not the headache
phase. However, this is a transient phenomenon preceding the headache.
Option B (Correct): During the headache phase of a migraine, cerebral and meningeal arteries
dilate. This vasodilation, combined with neurogenic inflammation, is thought to contribute to
the throbbing pain characteristic of migraines.
Option C: Cerebral arteries do not remain unchanged during migraine. Significant vascular
changes occur throughout the migraine process.
Option D: While neurogenic inflammation does occur, the primary vascular change is dilation.
Inflammation is a secondary process involving the release of inflammatory mediators.
3. Which medication is the first-line treatment for acute migraine in a patient without
contraindications?
A) Sumatriptan
,B) Acetaminophen
C) Ibuprofen
D) Metoclopramide
Correct ANSWER✔✨-: A) Sumatriptan
Rationale:
Option A (Correct): Triptans, particularly sumatriptan, are first-line treatments for moderate to
severe acute migraines. They act as serotonin receptor agonists, causing vasoconstriction and
reducing neurogenic inflammation.
Option B: Acetaminophen may be effective for mild migraines but is not first-line for moderate
to severe acute migraines. It has limited efficacy in treating migraine-associated symptoms.
Option C: NSAIDs like ibuprofen may help with mild to moderate migraines but are not
considered first-line for more severe attacks. They have gastrointestinal side effects with
prolonged use.
Option D: Metoclopramide is an antiemetic that can be used as adjunctive therapy for
migraine-associated nausea but is not the primary treatment for the headache itself.
4. A 45-year-old female presents with a severe headache, fever, and nuchal rigidity. What is the
most likely diagnosis?
A) Migraine
B) Tension headache
C) Meningitis
D) Cluster headache
, Correct ANSWER✔✨-: C) Meningitis
Rationale:
Option A: Migraine does not typically present with fever or nuchal rigidity. It is characterized by
throbbing pain, photophobia, and phonophobia.
Option B: Tension headaches present with bilateral, pressing/tightening quality without fever
or nuchal rigidity. They are not associated with systemic symptoms.
Option C (Correct): The triad of severe headache, fever, and nuchal rigidity is classic for
meningitis. This requires immediate evaluation and empiric antibiotic therapy.
Option D: Cluster headaches present with unilateral, severe orbital pain with autonomic
symptoms. They do not present with fever or nuchal rigidity.
5. What is the recommended duration of antibiotic therapy for uncomplicated acute bacterial
sinusitis?
A) 3-5 days
B) 5-7 days
C) 10-14 days
D) 21 days
Correct ANSWER✔✨-: B) 5-7 days
