AANPCB FNP Certification Exam (Family Nurse
Practitioner (FNP) Exam by AANPCB) New Latest
Version with 150 Questions, Answers and Rationales
Question 1
A 35-year-old male presents with a blood pressure of 150/95 mmHg on two separate visits. What
is the most appropriate initial treatment?
A) Hydrochlorothiazide
B) Atenolol
C) Furosemide
D) Lifestyle modifications alone
Correct Answer: A) Hydrochlorothiazide
Rationale: For stage 1 hypertension (140–159/90–99 mmHg), thiazide diuretics like
hydrochlorothiazide are first-line per JNC 8 guidelines, often combined with lifestyle changes.
Atenolol is not first-line, furosemide is for edema, and lifestyle alone is insufficient here.
Question 2
A 10-year-old child has a fever, rash, and joint pain following a recent sore throat. What is the
most likely diagnosis?
A) Kawasaki disease
B) Rheumatic fever
C) Juvenile idiopathic arthritis
D) Measles
Correct Answer: B) Rheumatic fever
Rationale: Fever, rash, and joint pain after a streptococcal infection suggest rheumatic fever, a
complication of untreated strep throat. Kawasaki involves coronary issues, arthritis lacks a rash
link, and measles has a distinct rash pattern.
Question 3
Which test confirms a diagnosis of diabetes mellitus in a 50-year-old patient with polydipsia?
A) Fasting glucose of 110 mg/dL
B) A1C of 6.2%
C) Random glucose of 210 mg/dL with symptoms
D) Oral glucose tolerance test of 180 mg/dL
Correct Answer: C) Random glucose of 210 mg/dL with symptoms
Rationale: Per ADA criteria, a random glucose ≥ 200 mg/dL with symptoms (e.g., polydipsia)
confirms diabetes. Fasting glucose ≥ 126 mg/dL, A1C ≥ 6.5%, or OGTT ≥ 200 mg/dL also
diagnose, but the scenario fits random glucose best.
Question 4
A 60-year-old female reports fatigue and cold intolerance. Which lab test should be ordered
first?
A) TSH
B) Serum cortisol
,C) Hemoglobin A1C
D) Complete blood count
Correct Answer: A) TSH
Rationale: Fatigue and cold intolerance suggest hypothyroidism, common in older adults. TSH is
the initial screening test. Cortisol tests adrenal function, A1C assesses diabetes, and CBC checks
anemia, but TSH aligns with symptoms.
Question 5
What is the most common causative organism of otitis media in children?
A) Streptococcus pneumoniae
B) Moraxella catarrhalis
C) Staphylococcus aureus
D) Pseudomonas aeruginosa
Correct Answer: A) Streptococcus pneumoniae
Rationale: S. pneumoniae is the leading cause of acute otitis media in children, followed by H.
influenzae and M. catarrhalis. S. aureus and P. aeruginosa are less common.
Question 6
A 28-year-old female with migraines asks about contraception. Which option is contraindicated?
A) Combined oral contraceptives
B) Progestin-only pill
C) Intrauterine device (IUD)
D) Depot medroxyprogesterone
Correct Answer: A) Combined oral contraceptives
Rationale: Combined oral contraceptives (estrogen + progestin) are contraindicated in migraines
with aura due to stroke risk (CDC MEC Category 4). Progestin-only options and IUDs are safer.
Question 7
Which finding in a 45-year-old male suggests benign prostatic hyperplasia (BPH)?
A) Nocturia and weak stream
B) Hematuria and fever
C) Flank pain and dysuria
D) Suprapubic pain and urgency
Correct Answer: A) Nocturia and weak stream
Rationale: BPH causes lower urinary tract symptoms like nocturia and weak stream due to
prostate enlargement. Hematuria/fever suggests infection or cancer, flank pain indicates stones,
and suprapubic pain points to bladder issues.
Question 8
A 15-year-old female presents with amenorrhea and a BMI of 16. What is the most likely cause?
A) Pregnancy
B) Anorexia nervosa
C) Polycystic ovary syndrome
D) Thyroid dysfunction
Correct Answer: B) Anorexia nervosa
Rationale: Amenorrhea with low BMI suggests anorexia nervosa, which disrupts the
,hypothalamic-pituitary-ovarian axis. Pregnancy requires testing, PCOS involves irregular cycles,
and thyroid issues need lab confirmation.
Question 9
What is the first-line treatment for a 30-year-old with uncomplicated community-acquired
pneumonia?
A) Azithromycin
B) Levofloxacin
C) Amoxicillin-clavulanate
D) Ceftriaxone
Correct Answer: A) Azithromycin
Rationale: Azithromycin, a macrolide, is first-line for outpatient CAP in healthy adults, covering
S. pneumoniae and atypicals (Mycoplasma, Chlamydia). Fluoroquinolones and broader-spectrum
drugs are reserved for comorbidities or resistance.
Question 10
A 70-year-old female has a FRAX score indicating high fracture risk. What is the most
appropriate treatment?
A) Calcium supplements alone
B) Alendronate
C) Vitamin D alone
D) Hormone replacement therapy
Correct Answer: B) Alendronate
Rationale: Bisphosphonates like alendronate are first-line for osteoporosis with high fracture risk
per AACE guidelines. Calcium and vitamin D are adjuncts, and HRT is less preferred due to
risks.
Question 11
Which symptom is most concerning in a 55-year-old with new-onset headache?
A) Photophobia
B) Sudden onset with vomiting
C) Tension in the neck
D) Pain relieved by ibuprofen
Correct Answer: B) Sudden onset with vomiting
Rationale: A sudden, severe headache with vomiting suggests a subarachnoid hemorrhage,
requiring urgent evaluation. Photophobia aligns with migraine, and tension/neck pain is less
acute.
Question 12
A 5-year-old has a barking cough and stridor. What is the most likely diagnosis?
A) Epiglottitis
B) Croup
C) Asthma
D) Foreign body aspiration
Correct Answer: B) Croup
Rationale: Barking cough and stridor in a young child are classic for croup (viral
, laryngotracheitis). Epiglottitis involves drooling and distress, asthma causes wheezing, and
aspiration is sudden.
Question 13
What is the target blood pressure for a 65-year-old with chronic kidney disease?
A) < 140/90 mmHg
B) < 130/80 mmHg
C) < 150/90 mmHg
D) < 120/80 mmHg
Correct Answer: B) < 130/80 mmHg
Rationale: KDIGO and AHA recommend < 130/80 mmHg for CKD to slow progression. Higher
targets apply to older adults without CKD, and < 120/80 is for specific high-risk cases.
Question 14
A 40-year-old male reports erectile dysfunction. Which condition should be screened first?
A) Hypothyroidism
B) Diabetes mellitus
C) Depression
D) Testosterone deficiency
Correct Answer: B) Diabetes mellitus
Rationale: Diabetes is a common cause of ED due to vascular and nerve damage, and screening
(e.g., A1C) is warranted. Other causes like depression or low testosterone are secondary
considerations.
Question 15
Which medication is contraindicated in a patient with asthma?
A) Lisinopril
B) Propranolol
C) Amlodipine
D) Hydrochlorothiazide
Correct Answer: B) Propranolol
Rationale: Nonselective beta-blockers like propranolol can trigger bronchospasm in asthma. The
others are generally safe in asthma patients.
Question 16
A 25-year-old female has a positive pregnancy test. When should prenatal care begin?
A) After 20 weeks
B) At 12 weeks
C) As soon as possible
D) At 8 weeks
Correct Answer: C) As soon as possible
Rationale: ACOG recommends starting prenatal care immediately after a positive test to
optimize maternal and fetal outcomes.
