CEA FNP Exam Test Bank 2025/2026 | 200+
Verified Questions, Answers & Rationales |
Comprehensive Family Nurse Practitioner
(FNP) Certification Study Guide | A+ Exam
Prep
• This comprehensive CEA FNP Exam Test Bank covers 200+ verified questions with
detailed EXPERT RATIONALE designed to mirror the actual Family Nurse
Practitioner certification exam experience across all core clinical domains.
• Study strategically by working through each question independently before
checking the correct answer and EXPERT RATIONALE — use the detailed
explanations to reinforce clinical reasoning, not just memorization.
Question 1
A 45-year-old woman presents with fatigue, weight gain, cold intolerance, and
constipation. TSH is 8.5 mIU/L and free T4 is low. What is the most appropriate
initial treatment?
A. Liothyronine (T3) alone
B. Combination T3/T4 therapy
C. No treatment; recheck in 6 months
D. Methimazole 10 mg daily
E. Levothyroxine (T4) replacement therapy
Correct Answer: E. Levothyroxine (T4) replacement therapy
EXPERT RATIONALE: Hypothyroidism presenting with classic symptoms and
confirmed by elevated TSH with low free T4 is treated with levothyroxine (synthetic
T4) as the first-line agent. T4 is peripherally converted to the active T3 form.
Methimazole is used for hyperthyroidism, not hypothyroidism. Combination
therapy is not routinely recommended as monotherapy with levothyroxine is
sufficient for most patients.
,Question 2
A 62-year-old male with type 2 diabetes and hypertension presents with a
blood pressure of 148/92 mmHg. His urine albumin-to-creatinine ratio is 350
mg/g. Which antihypertensive agent is most appropriate?
A. Amlodipine
B. Metoprolol succinate
C. Hydrochlorothiazide
D. Lisinopril
E. Clonidine
Correct Answer: D. Lisinopril
EXPERT RATIONALE: ACE inhibitors such as lisinopril are the first-line
antihypertensive agents for patients with diabetic nephropathy and proteinuria.
They reduce intraglomerular pressure and slow the progression of kidney disease.
ARBs are an acceptable alternative. Beta-blockers, calcium channel blockers, and
thiazides may be used as adjuncts but are not the preferred first-line agents in the
presence of proteinuria and diabetes.
Question 3
A 28-year-old woman at 10 weeks gestation presents with nausea, vomiting,
and a TSH of 0.1 mIU/L with elevated free T4. She has no goiter or
exophthalmos. What is the most likely diagnosis?
A. Graves' disease
B. Toxic multinodular goiter
C. Gestational transient thyrotoxicosis
D. Hashimoto thyroiditis
E. Subacute thyroiditis
Correct Answer: C. Gestational transient thyrotoxicosis
,EXPERT RATIONALE: Gestational transient thyrotoxicosis is caused by the TSH-like
effect of hCG during the first trimester, which can suppress TSH and mildly elevate
thyroid hormones. It is self-limiting and typically resolves by the second trimester.
The absence of goiter, exophthalmos, and thyroid antibodies differentiates it from
Graves' disease. Treatment is supportive with antiemetics and hydration.
Question 4
A 55-year-old man presents with sudden-onset severe headache described as
"the worst headache of my life." He is afebrile and neurologically intact. What
is the priority next step?
A. Prescribe sumatriptan and discharge
B. Perform a lumbar puncture immediately without imaging
C. Order a non-contrast CT scan of the head
D. Administer IV morphine and observe
E. Schedule an outpatient MRI
Correct Answer: C. Order a non-contrast CT scan of the head
EXPERT RATIONALE: A thunderclap headache described as the "worst headache of
life" must be evaluated urgently for subarachnoid hemorrhage (SAH). Non-contrast
CT of the head is the first-line diagnostic test, as it detects blood in up to 98% of
SAH cases within 12 hours of onset. If CT is negative but clinical suspicion remains
high, lumbar puncture is performed to detect xanthochromia. Discharging the
patient without evaluation is dangerous.
Question 5
A 7-year-old child is brought in with a 3-day history of fever, sore throat, and a
sandpaper-like rash on the trunk. Throat culture is positive for Group A
Streptococcus. What is the drug of choice?
A. Azithromycin
, B. Amoxicillin
C. Cephalexin
D. Clindamycin
E. Doxycycline
Correct Answer: B. Amoxicillin
EXPERT RATIONALE: Scarlet fever caused by Group A Streptococcus (GAS) is
treated with amoxicillin as the first-line antibiotic due to its efficacy, safety profile,
and narrow spectrum. Penicillin V is also acceptable. Azithromycin and clindamycin
are alternatives for penicillin-allergic patients. Doxycycline is contraindicated in
children under 8 years old. Early treatment prevents complications such as
rheumatic fever.
Question 6
A 68-year-old woman presents with progressive memory loss, confusion, and
inability to perform ADLs over 2 years. MMSE score is 18/30. She has no focal
neurological deficits. What is the most likely diagnosis?
A. Vascular dementia
B. Lewy body dementia
C. Frontotemporal dementia
D. Alzheimer's disease
E. Normal pressure hydrocephalus
Correct Answer: D. Alzheimer's disease
EXPERT RATIONALE: Alzheimer's disease is the most common cause of dementia,
presenting with gradual progressive memory loss, impaired ADLs, and cognitive
decline without focal neurological deficits. It predominantly affects short-term
memory first. Vascular dementia has a stepwise progression with focal deficits.
Lewy body dementia presents with visual hallucinations and parkinsonism. Normal
