APEA 3P PRACTICE TEST SET 2 2026
Family Nurse Practitioner (FNP) Review
• This comprehensive exam preparation resource contains practice questions with
verified answers and detailed rationales to assess mastery of FNP clinical
competencies and build confidence for the certification examination
• Study effectively by using these questions to identify knowledge gaps, practice
time management, reinforce critical clinical decision-making skills, and familiarize
yourself with the exam's format and question patterns
1. A 45-year-old female presents with a chief complaint of progressive
dyspnea on exertion over the past 3 months. She has a history of rheumatic
fever as a child. On cardiac auscultation, you hear an opening snap followed
by a rumbling diastolic murmur best heard at the apex with the patient in the
left lateral position. Which cardiac valve is most likely affected?
A) Aortic valve
B) Pulmonary valve
C) Mitral valve
D) Tricuspid valve
E) Left ventricular outflow tract
CORRECT ANSWER: C) Mitral valve
RATIONALE: The clinical presentation is classic for mitral stenosis. The opening
snap followed by a rumbling diastolic murmur at the apex is pathognomonic for
this condition. Rheumatic heart disease is the most common cause of mitral
,stenosis worldwide. The left lateral position enhances auscultation of mitral
pathology. Aortic stenosis produces a systolic ejection murmur, not a diastolic
murmur. Pulmonary and tricuspid involvement would produce different murmur
characteristics and locations.
2. A 28-year-old male presents with acute onset of severe, tearing chest pain
radiating to the back, associated with hypertension and a blood pressure
differential of 20 mmHg between his arms. Which imaging study should be
performed first?
A) Transthoracic echocardiogram
B) Cardiac catheterization
C) CT angiography with contrast
D) Chest X-ray
E) Transesophageal echocardiogram
CORRECT ANSWER: C) CT angiography with contrast
RATIONALE: Acute aortic dissection is suggested by the tearing chest pain,
hypertension, and blood pressure differential between arms. CT angiography with
IV contrast is the first-line imaging modality for suspected aortic dissection due to
its high sensitivity (95-98%), specificity, speed, and widespread availability. It can
also identify complications like pericardial effusion. While TEE is highly sensitive, CT
is faster and non-invasive as an initial study. Echocardiography and cardiac
catheterization are not first-line for aortic dissection evaluation.
3. A 52-year-old female with type 2 diabetes mellitus presents with polyuria,
polydipsia, and nausea. Laboratory values show: glucose 520 mg/dL, pH 7.28,
HCO3 18 mEq/L, and anion gap of 16. Which diagnosis is most likely?
,A) Diabetic ketoacidosis (DKA)
B) Hyperglycemic hyperosmolar state (HHS)
C) Lactic acidosis
D) Alcoholic ketoacidosis
E) Uremic acidosis
CORRECT ANSWER: A) Diabetic ketoacidosis (DKA)
RATIONALE: The anion gap metabolic acidosis (pH 7.28, HCO3 18, anion gap 16)
with severe hyperglycemia is consistent with DKA. The anion gap >12 indicates
organic acid accumulation (beta-hydroxybutyrate and acetoacetate). HHS typically
presents with glucose >600 mg/dL but without significant acidosis or anion gap
elevation. DKA occurs more commonly in type 1 diabetes but can occur in type 2,
particularly with stress or infection. Lactic acidosis and alcoholic ketoacidosis have
different clinical contexts.
4. A 34-year-old female with a history of systemic lupus erythematosus (SLE)
presents with pleuritic chest pain, dyspnea, and a new pleural friction rub.
Which medication would be most appropriate as first-line therapy?
A) Prednisone
B) Azathioprine
C) Methotrexate
D) Mycophenolate mofetil
E) Intravenous cyclophosphamide
CORRECT ANSWER: A) Prednisone
RATIONALE: Serositis (pleuritis) associated with SLE is optimally treated with
corticosteroids as first-line therapy. NSAIDs can be used for mild serositis, but with
moderate-to-severe symptoms and objective findings like a friction rub,
, corticosteroids are indicated. Prednisone at moderate doses (20-40 mg daily)
typically resolves lupus pleuritis within days. Azathioprine, methotrexate, and
mycophenolate are immunosuppressants used for refractory disease or steroid-
sparing effects. IV cyclophosphamide is reserved for severe renal or CNS lupus
involvement.
5. A 67-year-old male with hypertension presents with a sudden, severe
headache described as "the worst headache of my life," neck stiffness, and
photophobia. CT head without contrast is normal. Which is the most
appropriate next step?
A) Observe in the emergency department for 6 hours then discharge
B) Lumbar puncture for cerebrospinal fluid analysis
C) MRI of the brain with and without contrast
D) Transcranial Doppler ultrasound
E) Discharge home with close follow-up
CORRECT ANSWER: B) Lumbar puncture for cerebrospinal fluid analysis
RATIONALE: This presentation is classic for subarachnoid hemorrhage (SAH) from
thunderclap headache, meningeal signs (neck stiffness, photophobia), and
hypertension. Although CT without contrast is negative, a normal CT does not
exclude SAH. Lumbar puncture should be performed to evaluate for
xanthochromia and RBCs in CSF, which confirm SAH when CT is negative. This
occurs in approximately 15% of SAH cases. Observation without LP risks missing a
life-threatening diagnosis. MRI is not as sensitive as LP for SAH detection in this
acute setting.
