APEA 3P Predictor Exam 2026/2027
Comprehensive Study Guide, Practice
Questions, Test Bank Review, and Final
Exam Preparation Manual
Question 1: Digoxin Interaction
A patient on digoxin therapy is prescribed antacids. Which outcome is most likely to
occur?
A. Increased digoxin absorption
B. Decreased digoxin levels
C. Increased toxicity risk
D. No effect on digoxin levels
Correct Answer: B. Decreased digoxin levels
Rationale: Antacids reduce the absorption of digoxin in the gastrointestinal tract,
leading to decreased serum levels and reduced therapeutic effectiveness. This may
result in worsening heart failure symptoms or arrhythmias due to subtherapeutic
dosing. Increased absorption (A) and toxicity (C) are incorrect because antacids do
not enhance digoxin bioavailability. No effect (D) is also incorrect as drug–drug
interaction is clinically significant.
Question 2: Pyridium Adverse Effect
A patient is taking phenazopyridine (Pyridium) for a UTI. Which serious
complication should the nurse monitor for?
A. Nephrotoxicity
B. Hemolytic anemia
C. Hyperkalemia
D. Liver failure
Correct Answer: B. Hemolytic anemia
Rationale: Pyridium can cause hemolytic anemia, especially in patients with G6PD
deficiency. It is used only for symptomatic relief of UTI pain and not long-term
treatment. Nephrotoxicity (A), hyperkalemia (C), and liver failure (D) are not primary
known adverse effects of this drug.

Question 3: PCOS Pathophysiology
Which hormonal imbalance is most associated with polycystic ovary syndrome
(PCOS)?
A. Low insulin and estrogen
B. Increased insulin and androgens
C. Low progesterone and cortisol
D. High thyroid hormone levels
Correct Answer: B. Increased insulin and androgens
Rationale: PCOS is characterized by insulin resistance leading to hyperinsulinemia,
which stimulates excess androgen production. This results in hirsutism, acne, and
menstrual irregularities. Other options are incorrect because PCOS is not primarily a
thyroid, cortisol, or estrogen-deficiency disorder.
Question 4: Pregnancy Antihypertensives
Which medication is considered safe for hypertension management during pregnancy?
A. ACE inhibitors
B. Labetalol
C. Spironolactone
D. Losartan
Correct Answer: B. Labetalol
Rationale: Labetalol is commonly used for pregnancy-induced hypertension due to its
safety profile. ACE inhibitors (A), ARBs like losartan (D), and spironolactone (C) are
contraindicated due to fetal toxicity risks.
Question 5: Placenta Previa
Which clinical finding is most consistent with placenta previa?
A. Painful vaginal bleeding
B. Painless bright red bleeding
C. Severe abdominal cramping
D. Uterine rigidity with fever
Correct Answer: B. Painless bright red bleeding
Rationale: Placenta previa typically presents with painless, bright red vaginal bleeding
in the second or third trimester. Painful bleeding and uterine rigidity suggest placental
abruption, not previa.
,2026/2027
Question 6: Rheumatoid Arthritis
Which assessment finding supports a diagnosis of rheumatoid arthritis?
A. Cool, stiff joints
B. Tender, warm, swollen joints
C. Sudden unilateral joint pain
D. Joint deformity without inflammation
Correct Answer: B. Tender, warm, swollen joints
Rationale: RA is an autoimmune inflammatory disorder characterized by symmetrical
joint inflammation, warmth, and swelling. Cool joints (A) suggest osteoarthritis, while
sudden unilateral pain (C) suggests gout.
Question 7: Ototoxic Medications
Which medication class is most associated with ototoxicity?
A. Beta blockers
B. Aminoglycosides
C. Antacids
D. SSRIs
Correct Answer: B. Aminoglycosides
Rationale: Aminoglycosides can damage the auditory nerve, leading to hearing loss
and tinnitus. Loop diuretics and NSAIDs may also contribute, but beta blockers and
SSRIs are not ototoxic.
Question 8: Enterobiasis Treatment
What is the recommended treatment duration for Enterobius vermicularis (pinworm)?
A. Single dose only
B. 3 days
C. 2 weeks
D. 1 month
Correct Answer: C. 2 weeks
Rationale: Treatment includes an initial dose followed by a repeat dose in 2 weeks to
eliminate reinfection from eggs. Shorter or longer durations are not standard.
, 2026/2027
Question 9: Mean Corpuscular Volume (MCV)
MCV is primarily used to assess:
A. White blood cell function
B. Platelet activity
C. Types of anemia
D. Liver function
Correct Answer: C. Types of anemia
Rationale: MCV helps classify anemia as microcytic, normocytic, or macrocytic,
aiding in diagnosis of iron deficiency or B12 deficiency. It does not assess WBCs,
platelets, or liver function.
Question 10: Rhogam Administration
When is Rhogam typically administered during pregnancy?
A. 12–14 weeks
B. 20 weeks
C. 27–28 weeks
D. 36–38 weeks
Correct Answer: C. 27–28 weeks
Rationale: Rhogam is given at 28 weeks and within 72 hours postpartum if the
newborn is Rh-positive. Early or late administration is not standard unless sensitizing
events occur.
Question 11: Infective Endocarditis Lesions
Janeway lesions are best described as:
A. Painful finger nodules
B. Non-tender hemorrhagic lesions on hands/feet
C. Purulent pustules
D. Ulcerative skin lesions
Correct Answer: B. Non-tender hemorrhagic lesions on hands/feet
Rationale: Janeway lesions are painless, erythematous or hemorrhagic lesions
associated with infective endocarditis. Osler nodes, not Janeway lesions, are painful.
