APEA 3P NURSING PRACTICE EXAM BANK: 125
VERIFIED QUESTIONS WITH DETAILED
RATIONALES
Nursing / Medicine / Clinical Pathophysiology
• Maximize your success with this APEA 3P Nursing Exam
practice exam designed to reinforce essential assessment,
pharmacology, and pathophysiology concepts critical for
advanced nursing practice.
• The exam-style questions help strengthen clinical reasoning,
identify knowledge gaps, and build confidence for exam day.
A valuable resource for focused review and effective
preparation. Suitable for nurse practitioner students
preparing for the APEA 3P examination.
Section 1: Advanced Pathophysiology (Questions 1–42)
1. A 45-year-old patient presents with fatigue, weight gain,
cold intolerance, and constipation. Laboratory findings
reveal elevated TSH and low free T4. Which of the following
is the most likely diagnosis?
A. Graves' disease
B. Hashimoto's thyroiditis
, Page |2
C. Thyroid storm
D. Subclinical hyperthyroidism
CORRECT ANSWER: B. Hashimoto's thyroiditis
RATIONALE: Hashimoto's thyroiditis is an autoimmune disorder
characterized by elevated TSH and low free T4, resulting in
primary hypothyroidism. Clinical manifestations include fatigue,
weight gain, cold intolerance, and constipation. Graves' disease
causes hyperthyroidism. Thyroid storm is a severe hyperthyroid
state. Subclinical hyperthyroidism would present with low TSH.
2. A 65-year-old male with a history of hypertension and
smoking presents with sudden onset of severe, tearing chest
pain radiating to the back. Blood pressure is 190/110 mmHg.
Which of the following conditions should be suspected first?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
CORRECT ANSWER: C. Aortic dissection
RATIONALE: Aortic dissection presents with sudden, severe,
tearing chest pain that may radiate to the back. Risk factors
include hypertension and smoking. The classic presentation
includes a blood pressure differential between arms. Acute MI
pain is typically crushing or pressure-like. Pulmonary embolism
, Page |3
presents with sudden dyspnea and pleuritic chest pain.
Pericarditis pain is sharp and positional.
3. A 28-year-old woman presents with amenorrhea,
galactorrhea, and visual field defects. A pituitary adenoma is
suspected. Which of the following laboratory findings would
support this diagnosis?
A. Elevated prolactin
B. Elevated TSH
C. Elevated cortisol
D. Elevated ACTH
CORRECT ANSWER: A. Elevated prolactin
RATIONALE: Prolactin-secreting pituitary adenomas
(prolactinomas) cause elevated prolactin levels, leading to
amenorrhea and galactorrhea in women. Large adenomas can
compress the optic chiasm, causing visual field defects
(bitemporal hemianopsia). Elevated TSH is seen in primary
hypothyroidism. Elevated cortisol suggests Cushing's
syndrome. Elevated ACTH may indicate Cushing's disease.
4. Which of the following is a hallmark laboratory finding in
diabetic ketoacidosis (DKA)?
A. Serum bicarbonate > 22 mEq/L
B. Serum pH > 7.35
, Page |4
C. Anion gap > 12 mEq/L
D. Serum osmolality < 280 mOsm/kg
CORRECT ANSWER: C. Anion gap > 12 mEq/L
RATIONALE: DKA is characterized by an elevated anion gap
metabolic acidosis (anion gap > 12 mEq/L) due to increased
production of ketone bodies. Serum bicarbonate is typically low
(< 18 mEq/L), pH is acidic (< 7.35), and serum osmolality is
elevated (> 290 mOsm/kg) due to hyperglycemia.
5. A 55-year-old male with a 30-pack-year smoking history
presents with a new-onset cough, hemoptysis, and weight
loss. Chest X-ray reveals a right hilar mass. Which of the
following is the most likely diagnosis?
A. Tuberculosis
B. Sarcoidosis
C. Bronchogenic carcinoma
D. Pneumonia
CORRECT ANSWER: C. Bronchogenic carcinoma
RATIONALE: Bronchogenic carcinoma (lung cancer) is strongly
associated with smoking history. Classic presenting symptoms
include new-onset cough, hemoptysis, weight loss, and a hilar
mass on chest X-ray. Tuberculosis would present with fever,
night sweats, and upper lobe infiltrates. Sarcoidosis typically
presents with bilateral hilar adenopathy. Pneumonia would
present with fever and acute symptoms.
