Introduction: This examination is designed for the MSN 610 APEA Final Exam,
comprehensively assessing advanced clinical knowledge and decision-making skills
essential for nurse practitioner practice. It evaluates the ability to perform focused
and comprehensive health assessments, interpret diagnostic data, formulate
differential diagnoses, and develop evidence-based management plans across the
lifespan. The 150 multiple-choice and scenario-based questions integrate
pharmacology, pathophysiology, and preventive care within real-world clinical
contexts. Emphasis is placed on clinical reasoning, safe prescribing, and adherence
to current guidelines. Mastery of this content ensures readiness for advanced
practice certification and the delivery of high-quality, patient-centered care.

SECTION ONE: QUESTIONS 1–150
1. A 65-year-old female presents with gradual onset of fatigue, pallor, and
paresthesias in her lower extremities. Laboratory findings reveal macrocytic
anemia and low serum vitamin B12. Which of the following is the most
likely underlying cause?
,A. Iron deficiency
B. Folate deficiency
C. Pernicious anemia due to autoimmune destruction of gastric parietal cells
D. Chronic blood loss
RATIONALE: The combination of macrocytic anemia, neurologic symptoms
(paresthesias), and low B12 strongly suggests pernicious anemia, an autoimmune
condition leading to intrinsic factor deficiency and vitamin B12 malabsorption.
Iron deficiency would present with microcytic anemia; folate deficiency lacks
neurologic symptoms.
2. A 72-year-old male with hypertension and benign prostatic hyperplasia is
started on tamsulosin. The nurse practitioner should instruct the patient to:
A. Take the medication at bedtime only
B. Report any sudden loss of vision
C. Change positions slowly due to risk of orthostatic hypotension
D. Avoid all dairy products
RATIONALE: Tamsulosin is an alpha-1 adrenergic blocker that can cause
orthostatic hypotension, particularly after the first dose. Patients should be
educated to rise slowly. It is not associated with vision loss, and no dairy
restriction is necessary.
3. A 45-year-old female with asthma reports daily symptoms and nighttime
awakenings three times per week. She uses her short-acting beta-agonist
daily. According to the NAEPP guidelines, her asthma severity is classified
as:
A. Mild intermittent
B. Mild persistent
C. Moderate persistent
D. Severe persistent
RATIONALE: Daily symptoms, nighttime awakenings >1 time/week but not
nightly, and daily use of a rescue inhaler indicate moderate persistent asthma.
Severe persistent would involve symptoms throughout the day and frequent
nighttime awakenings.
, 4. A 2-year-old child presents with a barking cough, stridor at rest, and a
temperature of 101°F. The nurse practitioner suspects croup. Which of the
following is the first-line pharmacologic treatment for moderate to severe
croup?
A. Antibiotics
B. Oral or intramuscular dexamethasone
C. Albuterol nebulizer
D. Ipratropium bromide
RATIONALE: Corticosteroids (dexamethasone) reduce airway edema and are
the mainstay of treatment for croup. Antibiotics are not indicated unless there is
a secondary bacterial infection. Bronchodilators are ineffective because the
pathology is not bronchospasm.
5. A 32-year-old female with a history of migraines with aura requests a
reliable contraceptive method. Which of the following is contraindicated?
A. Progestin-only pill
B. Copper intrauterine device
C. Combined oral contraceptive pill
D. Depot medroxyprogesterone acetate
RATIONALE: Combined hormonal contraceptives containing estrogen are
contraindicated in women with migraines with aura due to an increased risk of
ischemic stroke. Progestin-only methods and non-hormonal IUDs are safe
alternatives.
6. An 80-year-old patient with atrial fibrillation is on warfarin. The INR today is
4.8, and the patient denies any bleeding. The most appropriate action is to:
A. Administer vitamin K 10 mg IV stat
B. Hold warfarin today and reduce the weekly dose; recheck INR in 1–2 days
C. Continue the current dose and recheck in one week
D. Admit to the hospital for observation
RATIONALE: For an INR between 4.5 and 10 without evidence of bleeding,
guidelines recommend holding one or two doses of warfarin, reducing the
, maintenance dose, and monitoring more frequently. IV vitamin K is reserved for
serious bleeding or extremely elevated INR.
7. A 58-year-old male with type 2 diabetes mellitus has an A1C of 8.5%
despite metformin monotherapy. The next step according to the ADA
treatment algorithm is to add:
A. Insulin glargine
B. Sulfonylurea
C. A GLP-1 receptor agonist or SGLT2 inhibitor, considering cardiovascular and
renal benefits
D. Pioglitazone
RATIONALE: For patients with established ASCVD, heart failure, or chronic
kidney disease, an SGLT2 inhibitor or GLP-1 receptor agonist with proven
cardiovascular benefit is recommended. Without these conditions, either class
may be considered, but the newer agents are preferred over sulfonylureas due to
weight and hypoglycemia advantages.
8. A 6-month-old infant is exclusively breastfed. Which nutrient supplement is
most important to recommend?
A. Vitamin C
B. Vitamin D 400 IU daily
C. Iron
D. Fluoride
RATIONALE: Exclusively breastfed infants are at risk for vitamin D deficiency
because breast milk is low in vitamin D. Supplementation of 400 IU/day is
recommended starting soon after birth. Iron supplementation may be considered
after 4–6 months if risk factors exist.
9. A 26-year-old female presents with sudden onset of severe lower
abdominal pain, vaginal bleeding, and a positive pregnancy test. She has a
history of pelvic inflammatory disease. The nurse practitioner should
suspect:
A. Threatened abortion
B. Appendicitis
