APEA 3P PREDICTOR EXAM
Actual Exam 250 Questions with Rationales
EXAM STRUCTURE & COVERAGE
The APEA 3P (Predictor, Practice, Proficiency) Exam evaluates Nurse Practitioner
readiness across three core domains:
1. Pathophysiology: Disease mechanisms, clinical manifestations, and diagnostic
reasoning.
2. Pharmacology: Drug classifications, mechanisms of action, prescribing safety,
and drug interactions.
3. Physical Assessment: Advanced health assessment techniques, abnormal
findings, and differential diagnosis.
EXAMINATION QUESTIONS
PATHOPHYSIOLOGY DOMAIN
1. A patient presents with acute shortness of breath, unilateral leg swelling, and
tachycardia. Which pathophysiological process is most likely responsible for this
presentation?
A) Left-sided heart failure with pulmonary edema
B) Deep vein thrombosis complicated by pulmonary embolism
C) Acute exacerbation of chronic obstructive pulmonary disease
D) Myocardial infarction with cardiogenic shock
Correct Answer: B
Rationale: Unilateral leg swelling strongly suggests deep vein thrombosis (DVT). The
acute dyspnea and tachycardia indicate that the DVT has embolized to the pulmonary
, Page 2 of 74
circulation, causing a pulmonary embolism. Left heart failure typically causes bilateral
edema .
2. A patient with chronic kidney disease (stage 4) develops hyperphosphatemia.
Which pathophysiological mechanism is the primary cause of this electrolyte
disturbance?
A) Increased dietary phosphate intake
B) Decreased renal excretion of phosphate
C) Increased bone resorption releasing phosphate
D) Decreased intestinal absorption of calcium
Correct Answer: B
Rationale: In chronic kidney disease, the decline in glomerular filtration rate leads to
phosphate retention. Hyperphosphatemia develops as the kidneys lose their ability to
excrete phosphate, and it is a key driver of secondary hyperparathyroidism in CKD .
3. Which of the following ECG findings is most consistent with hypokalemia?
A) Peaked T waves
B) U waves and flat T waves
C) Prolonged PR interval
D) ST-segment elevation
Correct Answer: B
Rationale: Hypokalemia classically causes U waves (seen as a small deflection
following the T wave), flat or inverted T waves, and ST depression. Peaked T waves are
characteristic of hyperkalemia .
4. A 62-year-old male presents with leg pain and occasional numbness that is
worse with ambulation and improved with lumbar flexion. What is the most likely
diagnosis?
A) Peripheral neuropathy
B) Spinal stenosis
C) Sciatica
D) Deep vein thrombosis
Correct Answer: B
Rationale: Spinal stenosis symptoms worsen with extension (standing/walking) and
improve with flexion (bending forward), distinguishing it from vascular claudication. This
is neurogenic claudication, caused by narrowing of the spinal canal .
5. A patient with heart failure with reduced ejection fraction (HFrEF) is on
metoprolol succinate, lisinopril, and furosemide. Which additional therapy is
guideline-directed for this patient?
A) Immediate-release nifedipine
, Page 3 of 74
B) Spironolactone (aldosterone antagonist)
C) Digoxin at high dose
D) Verapamil
Correct Answer: B
Rationale: Aldosterone antagonists (spironolactone, eplerenone) are guideline-
directed therapy for HFrEF to reduce mortality and hospitalizations. Immediate-release
nifedipine and verapamil are contraindicated in HFrEF as they may worsen heart failure .
6. A patient with acute pancreatitis has a lipase >3 times normal. Which is the most
common etiology?
A) Hypertriglyceridemia
B) Gallstones
C) Drug-induced
D) Post-ERCP
Correct Answer: B
Rationale: Gallstones and alcohol use are the two most common causes of acute
pancreatitis. Gallstones pass through the common bile duct and obstruct the
pancreatic duct, triggering pancreatic enzyme activation and inflammation .
7. What physical exam finding is characteristic of chronic liver disease?
A) Spider angiomas
B) Pallor of the palms
C) Dry, scaly skin
D) Peripheral edema without other stigmata
Correct Answer: A
Rationale: Spider angiomas, along with palmar erythema, gynecomastia, caput
medusae, and asterixis, are classic stigmata of chronic liver disease. These findings
reflect the hormonal and metabolic changes associated with hepatic dysfunction .
8. A pregnant patient at 16 weeks presents with blood pressure reduced from
118/79 to 109/68. What hemodynamic change is responsible for this?
A) Increased blood volume
B) Decreased systemic vascular resistance
C) Increased cardiac output
D) Increased heart rate
Correct Answer: B
Rationale: During pregnancy, systemic vascular resistance decreases due to
vasodilation mediated by progesterone and other hormonal changes. This leads to a
drop in blood pressure, particularly in the second trimester, despite increased blood
volume and cardiac output .

9. What clinical manifestation suggests primary syphilis?
A) Multiple painful genital ulcers
B) Single painless genital lesion (chancre)
C) Generalized rash with fever
D) Severe joint pain
Correct Answer: B
Rationale: Primary syphilis classically presents as a solitary, painless, indurated
chancre at the site of inoculation. This lesion is highly contagious and typically appears
3 weeks after exposure. Multiple painful ulcers suggest herpes or chancroid .
10. What finding would be suggestive of osteosarcoma in a pediatric patient?
A) Pain in the affected bone
B) Fever and chills
C) Skin rash over the area
D) Frequent fractures
Correct Answer: A
Rationale: Persistent, localized bone pain, especially if worse at night, is a key
symptom suggesting osteosarcoma in children and adolescents. The pain is often
initially attributed to growing pains or sports injury. Systemic signs are less common
early in the disease .
11. Which symptoms suggest bacterial meningitis in an adult?
A) Fever, nuchal rigidity, and altered mental status
B) Headache with photophobia only
C) Fever and rash without neurologic findings
D) Altered mental status without fever
Correct Answer: A
Rationale: Bacterial meningitis classically presents with fever, nuchal rigidity (neck
stiffness), and altered mental status. Kernig's and Brudzinski's signs may also be
present. Headache is almost universal, and the classic triad is found in the majority of
adult cases .
12. Which ECG finding is consistent with hyperkalemia?
A) U waves
B) Peaked T waves
C) Flat T waves
D) ST depression
Correct Answer: B
Rationale: Peaked (tall, tented) T waves are the earliest and most characteristic ECG
