PRACTICE TEST BOARD-STYLE QUESTIONS
& ANSWERS PROFESSOR VERIFIED
This premium practice exam features high-yield multiple-choice
questions complete with italicized correct answers and
comprehensive, bold-italic clinical rationales. It spans critical
nursing domains, high-alert pharmacology antidotes, complex
fluid/electrolyte pathophysiology, and foundational medical-
surgical interventions essential for board mastery. Perfect as a
rapid-review companion or ultimate testing simulator, this
resource targets the precise analytical frameworks needed to
pass advanced clinical nursing examinations.
1. A patient presents to the emergency department
with a suspected acute myocardial infarction.
Which diagnostic lab result is most specific for
confirming myocardial tissue damage?
A) Creatine kinase (CK-MB)
B) Myoglobin
C) Troponin I
D) Lactate dehydrogenase (LDH)
Answer: C
Rationale: Troponin I is highly specific to
myocardial tissue and remains elevated for 1
to 2 weeks following an acute myocardial
infarction, making it the gold standard
diagnostic biomarker. CK-MB is also useful
, but less specific than Troponin I, while
myoglobin rises quickly but lacks cardiac
specificity.
2. A nurse is preparing to administer secondary
intravenous plumbing (piggyback) containing an
antibiotic. To ensure the medication infuses
correctly via gravity, how should the nurse
position the fluid bags?
A) Hang the secondary bag lower than the
primary bag.
B) Hang the secondary bag higher than the
primary bag.
C) Position both bags at exactly the same
height.
D) Disconnect the primary bag entirely during
the infusion.
Answer: B
Rationale: When using a gravity infusion
setup, the secondary medication bag must
hang higher than the primary infusion bag.
The hydrostatic pressure from the higher
bag closes the backcheck valve on the
primary tubing, ensuring the secondary
medication infuses completely first.
,3. A patient diagnosed with chronic kidney disease
is prescribed epoetin alfa. Which laboratory
parameter must the nurse monitor closely to
evaluate the therapeutic efficacy of this
medication?
A) Serum potassium
B) Serum creatinine
C) Hematocrit and hemoglobin
D) Blood urea nitrogen (BUN)
Answer: C
Rationale: Epoetin alfa is a synthetic form of
erythropoietin that stimulates red blood cell
production in the bone marrow. The
therapeutic response is directly monitored
by tracking rises in hemoglobin and
hematocrit levels to resolve anemia.
4. During a physical assessment, a nurse notes a
high-pitched, musical whistling sound heard
primarily during expiration throughout the
patient's lung fields. How should the nurse
document this adventitious breath sound?
A) Crackles
B) Wheezes
C) Rhonchi
D) Pleural friction rub
, Answer: B
Rationale: Wheezes are continuous, high-
pitched musical sounds caused by air
squeezing through narrowed or
bronchoconstricted airways, commonly
noted during expiration in patients with
asthma or COPD.
5. A healthcare provider prescribes a low-sodium
diet for a patient with severe hypertension.
Which food choice selected by the patient
indicates a need for further dietary teaching?
A) Grilled chicken breast
B) Fresh steamed broccoli
C) Canned tomato soup
D) Brown rice
Answer: C
Rationale: Canned soups and processed
foods are notoriously high in sodium added
as a preservative. Fresh meats, vegetables,
and whole grains are naturally lower in
sodium and safer for hypertensive patients.
6. A nurse is reviewing a patient's arterial blood
gas (ABG) results: pH 7.31, PaCO2 52 mmHg,
and HCO3 24 mEq/L. Which acid-base
imbalance do these values represent?
