APEA 3P PREDICTOR EXAM 2025-2026 –PATHO,
PHARM & ASSESSMENT PRACTICE QUESTIONS
WITH CORRECT ANSWERS & DETAILED
RATIONALES,100% CORRECT ALREADY GRADED A+
1. Which cranial nerve is responsible for pupillary constriction?
A. CN II (Optic)
B. CN III (Oculomotor)
C. CN V (Trigeminal)
D. CN VII (Facial)
Answer: B. CN III (Oculomotor)
Rationale:
The oculomotor nerve (CN III) carries parasympathetic fibers that control
the sphincter pupillae muscle, which causes pupillary constriction when
stimulated (for example, in response to light). It also innervates muscles
responsible for most extraocular movements.
CN II (Optic) is sensory only, transmitting visual information from the
retina to the brain. It does not control movement or pupillary constriction
directly.
CN V (Trigeminal) controls facial sensation and muscles of mastication; it
has no role in eye movement or pupillary reflex.
CN VII (Facial) controls muscles of facial expression and some taste
sensation, but again, not pupillary function.
👉 In exams, remember: CN II detects the light, CN III makes the pupil
constrict.
,2. A client with COPD is prescribed tiotropium. Which teaching point is
correct?
A. “This medication is a rescue inhaler.”
B. “Rinse your mouth after use.”
C. “Expect this drug to act immediately.”
D. “Take this medication only when short of breath.”
Answer: B. “Rinse your mouth after use.”
Rationale:
Tiotropium is a long-acting anticholinergic bronchodilator (LAMA)
used for maintenance therapy in COPD. It is NOT a rescue inhaler and does
not provide immediate relief.
Clients should be taught to rinse their mouth after inhalation to reduce the
risk of dry mouth, throat irritation, and oral infections.
Option A: Incorrect – tiotropium is not for acute exacerbations; short-acting
beta-agonists (like albuterol) are used for rescue.
Option C: Incorrect – it has a slow onset; symptom improvement may take
days to weeks.
Option D: Incorrect – it must be taken regularly, not PRN, to maintain
bronchodilation.
👉 Key point: Tiotropium = daily maintenance, not rescue.
3. Which sound is heard with mitral regurgitation?
A. S3 gallop
B. Opening snap
C. Holosystolic murmur
D. Mid-systolic click
Answer: C. Holosystolic murmur
Rationale:
, Mitral regurgitation produces a holosystolic (pansystolic) murmur, best
heard at the cardiac apex and radiating to the left axilla. This occurs because
blood leaks back into the left atrium throughout systole.
Option A (S3 gallop): May occur in volume overload, but it is not specific
for MR.
Option B (Opening snap): Seen with mitral stenosis, not regurgitation.
Option D (Mid-systolic click): Classic for mitral valve prolapse (MVP),
not MR.
👉 Clinical pearl: Mitral regurgitation → holosystolic murmur radiating to
axilla.
4. Which lab test monitors warfarin therapy?
A. aPTT
B. PT/INR
C. Platelet count
D. Anti-Xa level
Answer: B. PT/INR
Rationale:
Warfarin inhibits vitamin K-dependent clotting factors (II, VII, IX, X). Its
anticoagulant effect is monitored with the Prothrombin Time (PT) and
International Normalized Ratio (INR). Therapeutic INR for most
conditions is 2.0–3.0.
Option A (aPTT): Monitors heparin therapy, not warfarin.
Option C (Platelet count): Detects thrombocytopenia, but does not reflect
anticoagulant effect.
Option D (Anti-Xa): Used to monitor low molecular weight heparin
(LMWH), not warfarin.
👉 NCLEX/NP exam favorite: Warfarin → PT/INR; Heparin → aPTT.
, 5. A client presents with left lower quadrant (LLQ) pain, fever, and
leukocytosis. Which condition is most likely?
A. Cholecystitis
B. Appendicitis
C. Diverticulitis
D. Pancreatitis
Answer: C. Diverticulitis
Rationale:
Diverticulitis typically presents with LLQ abdominal pain, fever,
leukocytosis, and sometimes constipation or diarrhea. It is caused by
inflammation of diverticula in the sigmoid colon.
Option A (Cholecystitis): Causes RUQ pain, often radiating to the
shoulder, with nausea/vomiting.
Option B (Appendicitis): Causes RLQ pain (McBurney’s point), anorexia,
nausea, and rebound tenderness.
Option D (Pancreatitis): Causes epigastric pain radiating to the back,
elevated amylase/lipase.
👉 Mnemonic: LLQ pain = think “Left-sided colon = Diverticulitis.”
6. A patient presents with fever, nuchal rigidity, and photophobia. Which
diagnostic test is most appropriate first?
A. Lumbar puncture
B. MRI of the brain
C. CT scan of the head
D. Blood cultures
Answer: C. CT scan of the head
