Introduction
The purpose of this assessment is to prepare candidates for the AANP national
certification examination. It is designed to evaluate the entry-level clinical knowledge
and skills of nurse practitioners. This comprehensive question bank assesses proficiency
in areas such as patient assessment, diagnostic reasoning, and evidence-based
management. The examination utilizes multiple-choice and scenario-based structures to
simulate clinical encounters. Emphasis is placed on real-world application, critical
thinking, and advanced clinical decision-making. By engaging with these questions,
candidates will demonstrate their ability to provide safe, effective, and ethical primary
care across the lifespan and diverse patient populations.
SECTION ONE: QUESTIONS 1–100
, 1. A 65-year-old male presents with a complaint of sudden onset of severe eye
pain, blurry vision, and seeing halos around lights. On examination, the pupil is
mid-dilated and non-reactive to light. What is the most likely diagnosis?
A. Cataracts
B. Macular degeneration
C. Acute angle-closure glaucoma
D. Retinal detachment
🟢 C. Acute angle-closure glaucoma
🔴 RATIONALE: Acute angle-closure glaucoma is a medical emergency characterized
by a rapid increase in intraocular pressure. Classic symptoms include severe eye pain,
halos around lights, and a fixed, mid-dilated pupil.
2. Which of the following heart sounds is considered a normal finding in a healthy,
athletic young adult but may indicate heart failure in an older adult?
A. S1
B. S2
C. S3
D. S4
🟢 C. S3
🔴 RATIONALE: An S3 gallop (ventricular gallop) is often normal in children and young
athletes due to rapid ventricular filling, but in older adults, it frequently signifies fluid
overload or heart failure.
, 3. An 18-year-old female presents with a sore throat, fever, and significant cervical
lymphadenopathy. A Monospot test is positive. Which activity should the nurse
practitioner advise the patient to avoid for at least 4 weeks?
A. Attending classes
B. Driving a vehicle
C. Contact sports
D. Eating spicy foods
🟢 C. Contact sports
🔴 RATIONALE: Infectious mononucleosis often causes splenomegaly. Patients must
avoid contact sports for 3–4 weeks to prevent the risk of splenic rupture, even if they
feel better.
4. A patient is prescribed Lisinopril for hypertension. Which electrolyte abnormality
is a known potential side effect of ACE inhibitors?
A. Hypokalemia
B. Hyperkalemia
C. Hyponatremia
D. Hypercalcemia
🟢 B. Hyperkalemia
🔴 RATIONALE: ACE inhibitors can cause the retention of potassium by inhibiting the
effects of aldosterone, potentially leading to hyperkalemia, especially in patients with
renal impairment.
, 5. A 4-year-old child presents with high fever, barking cough, and inspiratory
stridor. The nurse practitioner suspects Croup. What is the primary causative
organism?
A. Haemophilus influenzae
B. Parainfluenza virus
C. Streptococcus pneumoniae
D. Respiratory syncytial virus
🟢 B. Parainfluenza virus
🔴 RATIONALE: Parainfluenza virus is the most common cause of Croup
(laryngotracheobronchitis) in young children, characterized by subglottic airway
inflammation.
6. In a patient with iron deficiency anemia, what would the nurse practitioner expect
the laboratory results to show regarding Total Iron Binding Capacity (TIBC)?
A. Decreased TIBC
B. Increased TIBC
C. Normal TIBC
D. Absent TIBC
🟢 B. Increased TIBC
🔴 RATIONALE: In iron deficiency anemia, TIBC increases as the body attempts to
compensate for low iron levels by increasing the number of available binding sites on
transferrin.
