2026/2027
Acute Care Nurse Practitioner
(ACNP) Certification Exam Study
Guide 2026/2027 with Practice Tests,
Case-Based Reviews, and Advanced
Clinical Preparation
Question 1:
An acute care nurse practitioner is working in a public health initiative aimed at
reducing hospital-acquired infections. Which action best demonstrates population-
level impact?
A. Maintaining personal certification as an NP
B. Participating in hospital grand rounds
C. Reporting unusual infection clusters to public health authorities
D. Joining a professional nursing organization
Correct Answer: C. Reporting unusual infection clusters to public health
authorities
Rationale: Reporting unusual infection patterns supports surveillance systems that
identify outbreaks early and protect entire populations. While certification, education,
and professional involvement improve individual competence, they do not directly
influence population-level disease prevention. Public health reporting is a core
responsibility in preventing disease spread and improving community health
outcomes.
Question 2:
A patient with community-acquired pneumonia is allergic to penicillin and lacks
financial resources. What is the most appropriate NP intervention?
A. Prescribe an aerosolized antibiotic
B. Transfer to long-term care facility
C. Consult social services for assistance
D. Discharge without antibiotics
Correct Answer: C. Consult social services for assistance
Rationale: Social services can assist with medication access, insurance enrollment,
and financial support, ensuring safe discharge planning. Aerosol antibiotics are not
,2026/2027
first-line therapy for pneumonia. Transfer to long-term care is unnecessary without
clinical indication. Prescribing without addressing affordability risks nonadherence
and poor outcomes.
Question 3:
During preoperative evaluation, an NP detects an asymptomatic pulsatile abdominal
mass. What is the most appropriate next step?
A. Proceed with surgery
B. Order abdominal ultrasound
C. Obtain KUB X-ray
D. Schedule renal arteriogram
Correct Answer: B. Order abdominal ultrasound
Rationale: A pulsatile abdominal mass suggests an abdominal aortic aneurysm (AAA),
and ultrasound is the first-line, noninvasive diagnostic test. Surgery should be delayed
until evaluation is complete. KUB X-ray and arteriography are not initial screening
tools.
Question 4:
A disease affecting distal interphalangeal joints with Heberden and Bouchard nodes is:
A. Rheumatoid arthritis
B. Osteoporosis
C. Osteoarthritis
D. Gout
Correct Answer: C. Osteoarthritis
Rationale: Osteoarthritis involves degenerative joint disease affecting distal and
proximal interphalangeal joints, hips, knees, and spine. Heberden nodes occur at distal
joints and Bouchard nodes at proximal joints. Rheumatoid arthritis is inflammatory
and typically spares DIP joints.
Question 5:
A decision to prescribe a medication with significant side effects for long-term benefit
reflects which ethical principle?
A. Justice
B. Autonomy
,2026/2027
C. Beneficence
D. Fidelity
Correct Answer: C. Beneficence
Rationale: Beneficence involves acting in the patient’s best interest, even when
balancing risks and benefits. Autonomy relates to patient decision-making. Justice
concerns fairness in healthcare distribution. Fidelity refers to maintaining trust and
professional commitment.
Question 6:
A critically ill patient develops hypernatremia with hypotension and tachycardia.
Initial management should include:
A. Hypotonic fluid infusion immediately
B. 5% dextrose in water
C. 0.9% normal saline infusion
D. Fluid restriction
Correct Answer: C. 0.9% normal saline infusion
Rationale: The priority is restoring intravascular volume before correcting sodium
imbalance. Normal saline stabilizes circulation. Hypotonic fluids or fluid restriction
may worsen hemodynamic instability.
Question 7:
An elderly patient with penicillin and sulfa allergy develops a UTI. Best antibiotic
choice is:
A. Cephalexin
B. Ciprofloxacin
C. Amoxicillin
D. Ampicillin
Correct Answer: B. Ciprofloxacin
Rationale: Ciprofloxacin is a fluoroquinolone effective for UTIs and safe in
penicillin-allergic patients. Cephalosporins may cross-react with penicillins.
Amoxicillin and ampicillin are contraindicated due to allergy risk.
Question 8:
Which lab best reflects early nutritional response to therapy?
, 2026/2027
A. Serum albumin
B. Hemoglobin
C. Prealbumin
D. Total cholesterol
Correct Answer: C. Prealbumin
Rationale: Prealbumin has a short half-life and reflects recent nutritional changes.
Albumin changes slowly and is affected by hydration and liver function. Hemoglobin
and cholesterol are not direct nutritional markers.
Question 9:
A patient with metastatic cancer and severe pain requires optimal continuous
analgesia. Best option is:
A. Oral morphine PRN
B. Fentanyl patch only
C. IV PCA morphine with basal rate
D. Meperidine IM every 3 hours
Correct Answer: C. IV PCA morphine with basal rate
Rationale: PCA allows continuous, titratable pain control for severe cancer pain.
Meperidine is not recommended for chronic pain due to neurotoxicity. Fentanyl
patches are not ideal for rapid titration in acute severe pain.
Question 10:
Two weeks after chemotherapy, which symptom requires urgent reporting?
A. Fatigue
B. Alopecia
C. Fever
D. Nausea
Correct Answer: C. Fever
Rationale: Fever after chemotherapy suggests neutropenic infection, a medical
emergency. Alopecia, fatigue, and nausea are expected side effects but not
immediately life-threatening.
Question 11:
A patient with ICP of 25 mmHg secondary to hydrocephalus requires:
