GUIDE: 200 PRACTICE QUESTIONS WITH CORRECT ANSWERS,
DETAILED RATIONALES, AND COMPREHENSIVE REVISION
MATERIAL ACROSS ALL NURSING DISCIPLINES—DESIGNED FOR
NCLEX-RN SUCCESS AND NGN PROFICIENCY
Question 1: A nurse is assessing a client who has pneumonia. Which of
the following findings should the nurse expect?
A. Bradypnea
B. Dry cough
C. Crackles in lung bases
D. Decreased tactile fremitus
CORRECT ANSWER: C. Crackles in lung bases
Rationale: Pneumonia causes inflammation and fluid accumulation in
the alveoli, leading to crackles (rales) on auscultation, particularly in the
lung bases. Tachypnea, not bradypnea, is expected. A productive cough
with purulent sputum is typical, not dry. Tactile fremitus is increased,
not decreased, due to consolidation.
Question 2: A nurse is caring for a client who has an order for a 24-hour
urine collection. Which of the following actions should the nurse take?
A. Discard the first voiding of the collection period
B. Keep the urine container at room temperature
,C. Collect all urine including the first morning void
D. Use a separate container for each void
CORRECT ANSWER: A. Discard the first voiding of the collection period
Rationale: For a 24-hour urine collection, the nurse should have the
client void, discard that specimen, and then collect all subsequent urine
for the next 24 hours, including the final void at the end of the
collection period. The container should be refrigerated or kept on ice,
not at room temperature.
Question 3: A nurse is administering digoxin to a client with heart
failure. Which of the following findings indicates digoxin toxicity?
A. Heart rate of 62/min
B. Serum potassium of 4.0 mEq/L
C. Visual disturbances (halos around lights)
D. Blood pressure of 130/80 mm Hg
CORRECT ANSWER: C. Visual disturbances (halos around lights)
Rationale: Digoxin toxicity can cause visual disturbances including
yellow-green halos around lights, blurred vision, and photophobia.
Other signs include bradycardia (HR <60), not tachycardia, and GI
symptoms. Hypokalemia increases the risk of toxicity.
Question 4: A nurse is preparing to insert a nasogastric tube. Which of
the following is the correct length to insert the tube?
A. Measure from nose to xiphoid process
B. Measure from nose to earlobe to xiphoid process
,C. Measure from nose to umbilicus
D. Measure from mouth to sternum
CORRECT ANSWER: B. Measure from nose to earlobe to xiphoid
process
Rationale: The correct method for measuring NG tube insertion length
is from the tip of the nose to the earlobe to the xiphoid process. This
approximates the distance to the stomach. The other measurements
would result in incorrect placement.
Question 5: A nurse is assessing a client who has Alzheimer's disease.
Which of the following manifestations should the nurse expect?
A. Sudden onset of confusion
B. Rapidly progressive memory loss
C. Gradual memory loss and personality changes
D. Hallucinations as an early symptom
CORRECT ANSWER: C. Gradual memory loss and personality changes
Rationale: Alzheimer's disease is characterized by gradual, progressive
cognitive decline including memory loss, confusion, and personality
changes over years. Sudden onset suggests delirium, and hallucinations
are not an early symptom.
Question 6: A nurse is caring for a client receiving total parenteral
nutrition (TPN). Which of the following actions is most important?
A. Monitor blood glucose levels
B. Change the IV tubing every 24 hours
, C. Weigh the client daily
D. Administer TPN through a peripheral IV
CORRECT ANSWER: A. Monitor blood glucose levels
Rationale: TPN has high glucose content, putting clients at risk for
hyperglycemia. Monitoring blood glucose is essential to prevent
complications. TPN is usually given through a central line due to its
hypertonicity. Tubing should be changed every 24 hours, but glucose
monitoring is priority.
Question 7: A nurse is reinforcing teaching with a client about self-
administration of insulin. Which of the following indicates correct
understanding?
A. "I will inject insulin into my deltoid muscle"
B. "I will rotate injection sites within the same body region"
C. "I will use the same site for all injections"
D. "I will aspirate before injecting insulin"
CORRECT ANSWER: B. "I will rotate injection sites within the same
body region"
Rationale: Insulin should be injected subcutaneously, and rotating sites
within the same region (e.g., abdomen, thighs) prevents lipodystrophy.
Aspiration is not recommended for insulin, and it is not given
intramuscularly.
Question 8: A nurse is assessing a client who is 1 day postpartum.
Which of the following findings should be reported to the provider?
