LATEST UPDATE 2025/2026
Question 1
An elderly client with diabetes Mellitus Type II has a syncopal episode 2 days after an abdominal
hysterectomy. Her vital signs are within normal limits, and her blood sugar is 325 mg/dL. What
intervention should the nurse implement first?
A) Administer a prescribed antiemetic.
B) Encourage increased oral fluid intake.
C) Administer regular insulin per sliding scale.
D) Assess for signs of dehydration.
E) Ambulate the client to the bathroom.
Correct Answer: C) Administer regular insulin per sliding scale
Rationale: The client's blood sugar is significantly elevated (325 mg/dL), which
requires immediate intervention, especially given her diabetic status and recent
surgery. Administering regular insulin per sliding scale is the most direct and
prioritized action to lower the blood glucose and prevent further complications
from hyperglycemia. While other options like assessing for dehydration or
encouraging fluids are important, addressing the acute hyperglycemia takes
precedence.
Question 2
A 3-week-old infant is admitted for surgical repair of Pyloric Stenosis. What interventions
should the nurse expect to implement to establish hydration in the immediate postoperative
period?
A) Nipple feedings with formula.
, B) Nipple feedings with glucose water.
C) Intravenous fluids with electrolytes.
D) Oral rehydration solution (ORS) via syringe.
E) Clear liquids via nasogastric tube.
Correct Answer: C) Intravenous fluids with electrolytes
Rationale: In the immediate postoperative period following pyloric stenosis repair,
the infant is at risk for dehydration and electrolyte imbalances. Intravenous fluids
with electrolytes are crucial for rehydration and maintaining electrolyte balance
until oral feedings are gradually introduced and tolerated. Nipple feedings would
typically be introduced cautiously and progressed slowly, not as the initial method
for hydration in the immediate postoperative phase.
Question 3
A 3-year-old admitted with fever of unknown origin (FUO) has begun vomiting in the past half
hour. The child's temperature is 101.8°F (38.8°C), and the last dose of antipyretic medication
was given 5 hours ago. The child has prescriptions for acetaminophen (Tylenol) 160 mg per 5
mL elixir or 160 mg suppositories PRN fever or pain. What action should the nurse take at this
time?
A) Make the child NPO and hold all medications until the vomiting has stopped.
B) Administer acetaminophen elixir orally.
C) Administer acetaminophen suppository rectally.
D) Notify the healthcare provider for further orders.
E) Provide small sips of clear fluids.
Correct Answer: C) Administer acetaminophen suppository rectally.
