APEA 3P Actual Exam Test Bank 2026 –Verified Questions &
Answers with Detailed Rationales | Advanced Pathophysiology,
Pharmacology & Physical Assessment Study Guide
This study resource is built for nurse practitioner students preparing for the APEA 3P
Predictor Exam. It mirrors the style, difficulty, and topic coverage of the APEA blueprint,
covering the three Ps—advanced pathophysiology, advanced pharmacotherapeutics, and
advanced physical assessment—across all body systems and the lifespan. The 300 unique
MCQs include verified updated answers and detailed rationales
1. A 72-year-old male with a history of hypertension and type 2 diabetes presents
with a 3-day history of severe, tearing chest pain radiating to his back. His blood
pressure is 180/100 mmHg in the right arm and 140/80 mmHg in the left arm. What
is the most likely diagnosis?
A) Acute myocardial infarction
B) Aortic dissection
C) Pulmonary embolism
D) Pericarditis
Explanation: The sudden onset of severe tearing chest pain radiating to the back with a
significant inter-arm blood pressure differential is the classic presentation of aortic
dissection. This is a hypertensive emergency requiring immediate CT angiography for
confirmation and surgical consultation.
2. A 50-year-old male experiences difficulty achieving and maintaining an erection.
This condition is MOST likely a result of:
A) Obstructive sleep apnea
B) Cardiovascular disease
C) An endocrine disorder
D) Benign prostatic hypertrophy
,Explanation: Erectile dysfunction is most commonly caused by cardiovascular disease, as
the penile arteries are smaller and often affected by atherosclerosis earlier than coronary
arteries. Vascular causes account for the majority of ED cases.
3. A 40-year-old patient is suspected of having a thyroid nodule. Initial evaluation
begins with ordering a(n):
A) CT scan and a thyroid-stimulating hormone level
B) Thyroid-stimulating hormone (TSH) level and thyroid ultrasound
C) Thyroid panel and thyroid scintigraphy
D) Referral to a surgeon for fine-needle biopsy
Explanation: The initial evaluation of a suspected thyroid nodule includes a TSH level to
assess thyroid function and a thyroid ultrasound to characterize the nodule's size,
composition, and features. Fine-needle aspiration is reserved for nodules that meet specific
sonographic criteria.
4. A child complains of "hurting a lot" when swallowing and states that his "throat
feels full." His sore throat started 4 days ago. He exhibits hyperextension of the neck.
Examination reveals asymmetrical swelling of the tonsils. His uvula is deviated to the
left. What is the most likely diagnosis?
A) Peritonsillar abscess
B) Laryngotracheobronchitis
C) Foreign body aspiration
D) Epiglottitis
Explanation: Unilateral tonsillar swelling with uvular deviation, severe odynophagia, and
neck hyperextension (torticollis-like positioning) are classic for peritonsillar abscess.
Epiglottitis presents with tripod positioning, drooling, and stridor rather than uvular
deviation.
,5. A 38-year-old patient reports that they may have been exposed to syphilis. The
patient was treated for syphilis 4 years ago. The nurse practitioner knows that:
A) A T. pallidum enzyme immunoassay (TP-EIA) is a qualitative test and will determine if she
has been reinfected.
B) A fluorescent treponemal antibody absorption (FTA-ABS) test will confirm a diagnosis of
syphilis in this patient.
C) There is no need to retest the patient; she should be treated empirically.
D) A rapid plasma reagin (RPR) test will provide a semiquantitative result, and a
fourfold increase may indicate a new infection.
Explanation: The RPR is a nontreponemal test that provides a quantitative titer. In a patient
with a history of treated syphilis, a fourfold increase in RPR titer (e.g., from 1:2 to 1:8)
suggests reinfection rather than residual antibody. Treponemal tests like TP-EIA and FTA-
ABS remain positive for life and cannot distinguish past from new infection.
6. A guardian calls the clinic today to report that their 3-year-old child continues to
have ear pain and a temperature of 100.4°F despite treatment with ibuprofen every 6
hours. The child, who is in good general health, was started on amoxicillin yesterday
for acute otitis media in his right ear. The nurse practitioner should instruct the
guardian to:
A) Stop the amoxicillin. The NP should prescribe a broader spectrum antibiotic.
B) Alternate ibuprofen and acetaminophen every 4 hours for the next 24 to 48 hours.
C) Continue the treatment regimen and call back if the child's temperature remains
100.4°F or greater, or if the pain continues for more than 48-72 hours after the
phone conversation.
D) Return to the office and re-examine the child for a tympanic membrane rupture.
Explanation: After initiating antibiotics for acute otitis media, symptoms may take 48-72
hours to resolve. Persistent fever and pain within this window are expected. The guardian
, should continue the current regimen and call back if symptoms do not improve within 48-72
hours or worsen.
7. A 19-year-old daycare worker presents with complaints of diarrhea and flatulence.
The patient reports a recent outbreak of Giardia in the daycare center. In the United
States, the first-line treatment for Giardia in a nonpregnant adult is:
A) Tinidazole
B) Metronidazole
C) Nitazoxanide
D) Paromomycin
Explanation: Tinidazole is a first-line treatment for giardiasis in nonpregnant adults due to
its efficacy and shorter course (single dose) compared to metronidazole. It is a
nitroimidazole antiprotozoal with a longer half-life than metronidazole.
8. A 58-year-old male presents for a routine physical examination. During the cardiac
exam, the NP notes a high-pitched, blowing decrescendo murmur at the right upper
sternal border that radiates to the carotids. What is the most likely diagnosis?
A) Mitral regurgitation
B) Aortic stenosis
C) Aortic regurgitation
D) Tricuspid stenosis
Explanation: Aortic stenosis classically presents as a high-pitched, blowing decrescendo
murmur at the right upper sternal border that radiates to the carotids. Mitral regurgitation
is a holosystolic murmur at the apex.
