Correct Answer: D

Rationale: Abdominal distention and rigidity may indicate a postoperative complication, such as bowel obstruction or peritonitis, and should be reported to the provider. While monitoring urine output, heart rate, and wound drainage are essential postoperative assessments, they are not as concerning as abdominal distention and rigidity, which could signal a more urgent issue requiring immediate attention.

Correct Answer: C

Rationale: In acute pancreatitis, the gastrointestinal tract needs to rest to reduce pancreatic enzyme secretion. Inserting a nasogastric tube for suction helps decompress the stomach and reduce stimulation of the pancreas. Encouraging oral intake of clear liquids (Choice A) or administering an antiemetic before meals (Choice B) may aggravate the condition by stimulating the pancreas. Placing the client in a supine position (Choice D) may not directly address the underlying issue of reducing pancreatic stimulation.

Correct Answer: B

Rationale: The correct answer is B: Amylase. Amylase is typically elevated in clients with acute pancreatitis due to inflammation of the pancreas. Elevated serum creatinine levels are more indicative of kidney dysfunction rather than pancreatitis. Hemoglobin levels are not directly related to pancreatitis. While blood glucose levels can be affected by pancreatitis, they are not typically the primary laboratory result expected to be elevated in this condition.

Correct Answer: B

Rationale: Checking gastric residual volumes every 6 hours is essential in preventing aspiration in clients receiving continuous enteral feedings. This practice helps determine if the stomach is adequately emptying, reducing the risk of regurgitation and aspiration. Elevating the head of the bed to 30 degrees, not 15 degrees, is recommended to further prevent aspiration by reducing the risk of reflux. Monitoring the pH of gastric aspirate is important to assess tube placement but does not directly prevent aspiration. Instilling air into the tube before feeding is not a recommended practice and does not prevent aspiration.

Correct Answer: A

Rationale: Corrected Rationale: Bradypnea, or slow breathing, is a common sign of opioid toxicity. When a client is experiencing opioid toxicity, the respiratory system is usually the most affected, leading to a decrease in the respiratory rate (bradypnea). Tachycardia (increased heart rate), hypertension (high blood pressure), and diaphoresis (excessive sweating) are not typical manifestations of opioid toxicity. Therefore, the correct answer is bradypnea.
