AANP FNP Certification Exam – Comprehensive Questions and
Answers with Detailed Rationales
1. Hypertension
A 52-year-old patient has repeated office blood pressures of 154/94
mmHg. Which diagnosis is most appropriate?
A. Normal blood pressure
B. Elevated blood pressure
C. Stage 1 hypertension
D. Stage 2 hypertension
Correct answer: D. Stage 2 hypertension
Rationale: A blood pressure of ≥140 systolic or ≥90 diastolic meets the
threshold for stage 2 hypertension under commonly used ACC/AHA
classifications. Diagnosis should be confirmed with appropriate
repeated measurements and, when appropriate, home or ambulatory
monitoring.
2. Diabetes Screening
Which test is commonly used to diagnose diabetes mellitus?
A. Hemoglobin A1c
B. Serum insulin
C. C-peptide alone
D. Urine ketones
Correct answer: A. Hemoglobin A1c
Rationale: An HbA1c of ≥6.5% on appropriate confirmatory testing is
one accepted diagnostic criterion for diabetes. It reflects average
glycemic exposure over approximately the preceding 2–3 months.
,3. Type 2 Diabetes
A newly diagnosed patient with type 2 diabetes has no contraindication
to metformin. Which medication is commonly considered an initial
pharmacologic option?
A. Metformin
B. Regular insulin for every patient
C. Glyburide exclusively
D. Acarbose exclusively
Correct answer: A. Metformin
Rationale: Metformin remains a commonly used initial glucose-
lowering medication because of its efficacy, safety profile, low cost, and
generally favorable effect on weight. Current treatment should also
account for cardiovascular, renal, weight, and hypoglycemia
considerations.
4. Hypoglycemia
Which symptom is most characteristic of hypoglycemia?
A. Bradycardia with hypothermia
B. Diaphoresis and tremulousness
C. Hyperreflexia with jaundice
D. Constipation and dry skin
Correct answer: B. Diaphoresis and tremulousness
Rationale: Adrenergic manifestations of hypoglycemia include
sweating, tremor, palpitations, anxiety, and hunger. Neuroglycopenic
,manifestations can include confusion, behavioral changes, seizures, and
loss of consciousness.
5. Asthma
Which medication is used as a controller medication for persistent
asthma?
A. Inhaled corticosteroid
B. Oral diphenhydramine
C. Benzonatate
D. Guaifenesin
Correct answer: A. Inhaled corticosteroid
Rationale: Inhaled corticosteroids reduce airway inflammation and are
foundational controller therapy for persistent asthma. Treatment is
adjusted according to symptom control, exacerbation risk, and the
patient's current regimen.
6. COPD
Which finding is particularly characteristic of chronic obstructive
pulmonary disease?
A. Persistent airflow limitation
B. Reversible isolated upper-airway obstruction
C. Acute pleural inflammation
D. Restrictive lung disease exclusively
Correct answer: A. Persistent airflow limitation
Rationale: COPD is characterized by persistent respiratory symptoms
and airflow limitation, generally caused by airway and/or alveolar
, abnormalities associated with significant exposure to noxious particles
or gases.
7. Community-Acquired Pneumonia
A patient presents with fever, productive cough, pleuritic chest pain,
and focal crackles. Which diagnosis should be strongly considered?
A. Community-acquired pneumonia
B. Migraine
C. Allergic rhinitis
D. Gastroesophageal reflux alone
Correct answer: A. Community-acquired pneumonia
Rationale: Fever, cough, pleuritic pain, and focal pulmonary findings
are compatible with pneumonia. Diagnosis and treatment depend on
clinical severity, imaging when indicated, comorbidities, and local
recommendations.
8. Streptococcal Pharyngitis
Which finding favors streptococcal pharyngitis over uncomplicated viral
pharyngitis?
A. Cough
B. Rhinorrhea
C. Tender anterior cervical adenopathy
D. Conjunctivitis
Correct answer: C. Tender anterior cervical adenopathy
Rationale: Fever, tonsillar exudates, tender anterior cervical nodes, and
absence of cough are classic features associated with group A
