APEA 3P Exam | Complete Practice Questions, Verified
Answers & Detailed Rationales (2026/2027)
QUESTION 1
A patient with chronic heart failure presents with worsening dyspnea
and fluid overload. The nurse practitioner knows that neurohormonal
activation in heart failure involves chronic stimulation of which
systems?
A. Sympathetic nervous system and renin-angiotensin-aldosterone
system
B. Parasympathetic cholinergic vagal pathway
C. Atrial natriuretic peptide secretory axis
D. Kallikrein-kinin vasodilator pathway
Correct Answer: A Sympathetic nervous system and renin-angiotensin-
aldosterone system
Rationale: Heart failure triggers chronic activation of the sympathetic
nervous system and the renin-angiotensin-aldosterone system, driving
harmful cardiac remodeling and fluid retention.
QUESTION 2
When evaluating sensory function of Cranial Nerve V (trigeminal nerve),
the nurse practitioner assesses light touch sensation over which
anatomical regions?
,A. Forehead, cheek, and jaw
B. Posterior scalp and neck
C. Lateral tongue and pharynx
D. External auditory meatus and earlobe
Correct Answer: A Forehead, cheek, and jaw
Rationale: Cranial Nerve V provides sensory innervation to the face
through its three divisions: ophthalmic (V1 - forehead), maxillary (V2 -
cheek), and mandibular (V3 - jaw).
QUESTION 3
Which anticoagulant medication exerts its therapeutic effect by directly
inhibiting factor Xa without requiring routine international normalized
ratio monitoring?
A. Warfarin
B. Apixaban
C. Unfractionated heparin
D. Argatroban
Correct Answer: B Apixaban
Rationale: Apixaban is a direct oral anticoagulant that selectively
inhibits factor Xa, preventing thrombin generation without requiring
routine monitoring.
QUESTION 4
,The primary cellular defect underlying the development of type 2
diabetes mellitus is:
A. Absolute autoimmune destruction of pancreatic beta cells
B. Peripheral insulin resistance coupled with relative insulin deficiency
C. Ectopic hypersecretion of glucagon from alpha cells
D. Accelerated hepatic clearance of circulating insulin
Correct Answer: B Peripheral insulin resistance coupled with relative
insulin deficiency
Rationale: Type 2 diabetes is characterized by peripheral target tissue
resistance to insulin combined with progressive pancreatic beta-cell
dysfunction and relative insulin deficiency.
QUESTION 5
To evaluate for a meniscal tear of the knee joint during physical
examination, the clinician performs the:
A. Lachman test
B. McMurray test
C. Valgus stress test
D. Anterior drawer test
Correct Answer: B McMurray test
Rationale: The McMurray test assesses for meniscal tears by flexing and
rotating the knee while applying varus or valgus stress to trap the torn
meniscus.
, QUESTION 6
The primary structural and functional difference in airway pathology
between asthma and chronic obstructive pulmonary disease is that
asthma features:
A. Irreversible fixed airflow obstruction driven entirely by neutrophils
B. Fully reversible or variable airway obstruction driven by eosinophilic
and mast cell inflammation
C. Destruction of alveolar walls resulting in permanent emphysema
D. Goblet cell metaplasia without smooth muscle hyperreactivity
Correct Answer: B Fully reversible or variable airway obstruction driven
by eosinophilic and mast cell inflammation
Rationale: Asthma is characterized by episodic, variable bronchospasm
and eosinophil-mediated inflammation that typically shows significant
reversibility with bronchodilators.
QUESTION 7
Tetracycline antibiotics are contraindicated for use in children under the
age of eight and pregnant women primarily because they cause:
A. Irreversible sensorineural hearing loss
B. Permanent tooth discoloration and enamel hypoplasia
C. Severe aplastic anemia and bone marrow suppression
D. Bilateral renal cortical necrosis
