Question 1
A nurse is caring for a patient with dysphagia. Which intervention is most appropriate to prevent aspiration during
mealtime?
A. Offer thin liquids to facilitate easier swallowing
B. Encourage the patient to tilt their head back while swallowing
C. Provide a straw for all liquid intake
D. Instruct the patient to perform the chin-tuck maneuver
Answer: D
Rationale
The chin-tuck maneuver helps close off the airway and opens the esophagus, reducing the risk of aspiration. Thin liquids and
straws increase aspiration risk in dysphagia patients. Understanding this concept is essential for safe clinical decision-making.
Incorrect choices often reflect common misconceptions. Always link assessment findings to the primary process and
anticipated complications.
Question 2
What is the gold standard for verifying the initial placement of a nasogastric (NG) tube before starting enteral feedings?
A. Auscultation of an air bolus in the epigastric region
B. Radiographic (X-ray) confirmation
C. pH testing of aspirated gastric contents
D. Observation of bubbling when the tube end is placed in water
Answer: B
Rationale
X-ray is the only definitive method to verify NG tube placement. Auscultation is no longer considered reliable for initial
verification. Understanding this concept is essential for safe clinical decision-making. Incorrect choices often reflect common
misconceptions. Always link assessment findings to the primary process and anticipated complications.
Question 3
A patient is receiving Total Parenteral Nutrition (TPN) via a central line. The nurse notes the bag is nearly empty, and
the next bag is not yet available from the pharmacy. What is the priority nursing action?
A. Flush the line with Heparin and wait for the new bag
B. Discontinue the infusion and monitor for hypoglycemia
C. Slow the current infusion rate to a keep-vein-open (KVO) rate
D. Hang a bag of 10% Dextrose in water (D10W)
Answer: D
Rationale
Abruptly stopping TPN can cause rebound hypoglycemia. Hanging D10W maintains blood glucose levels until the next TPN
bag is available. Understanding this concept is essential for safe clinical decision-making. Incorrect choices often reflect
common misconceptions. Always link assessment findings to the primary process and anticipated complications.
