Question 1
The registered nurse (RN) is caring for a young adult who is having an oral glucose
tolerance test (OGTT). Which laboratory result should the RN assess as a normal
value for the two-hour postprandial result?
• A. 140 mg/dL
• B. 160 mg/dL
• C. 180 mg/dL
• D. 200 mg/dL
Correct Answer: A. 140 mg/dL
✅ Rationale:
• The two-hour postprandial glucose level should be <140 mg/dL for a young
adult.
• Values ≥200 mg/dL indicate diabetes, while 140–199 mg/dL suggest
prediabetes.
Question 2
The RN is caring for a client with a closed head injury. Which finding should the
RN assess as a risk for diabetes insipidus (DI)?
, • A. High fever
• B. Low blood pressure
• C. Muscle rigidity
• D. Polydipsia
Correct Answer: D. Polydipsia
✅ Rationale:
• DI occurs due to ADH deficiency, often from pituitary/hypothalamus
damage (e.g., head trauma).
• Classic symptoms:
o Excessive urination (5–20 L/day)
o Polydipsia (extreme thirst) to compensate for fluid loss.
Question 3
A client with sepsis and dehydration had oliguria. Which finding indicates
stabilization?
• A. Urine output of 40 mL/hour
• B. BP 76/42, pulse 100
• C. Urine specific gravity 1.001
• D. Tented skin on hands
Correct Answer: A. Urine output of 40 mL/hour
✅ Rationale:
• Normal urine output = 30–50 mL/hour.
• Oliguria = <400 mL/day (or <20 mL/hour).
• 40 mL/hour indicates improved kidney perfusion and hydration status.
, Question 4
A client using ipratropium reports nausea, blurred vision, headaches, and
insomnia. What should the RN do first?
• A. Withhold medication and report symptoms
• B. Give antiemetics and reassess
• C. Reassure client symptoms will resolve
• D. Delay next dose
Correct Answer: A. Withhold medication and report symptoms
✅ Rationale:
• Symptoms suggest anticholinergic toxicity (ipratropium is an anticholinergic).
• Priority action: Hold the drug and notify the provider to prevent complications.
Question 5
A hypertensive client is discharged home. Which equipment should the RN
recommend?
• A. Exercise bicycle
• B. Sphygmomanometer
• C. Blood glucose monitor
• D. Weekly pillbox
Correct Answer: B. Sphygmomanometer
✅ Rationale:
• Home BP monitoring improves adherence and control.
• Teach the client to record daily readings and recognize abnormal trends.
