Correct Answer: D

Rationale: The correct answer is D because feeding the infant with a rubber-tipped syringe reduces the risk of injury to the surgical site and prevents aspiration. Choice A is incorrect because feeding in the recumbent position can increase the risk of aspiration. Choice B is incorrect as Betadine is not recommended for wound care near the mouth due to its potential toxicity if ingested. Choice C is incorrect because placing the infant in the prone position after feeding can increase the risk of regurgitation and aspiration.

Correct Answer: D

Rationale: Assisting the client to sit in a chair is an essential nursing intervention postoperatively as it helps promote circulation, prevent complications like blood clots, and aids in the recovery process. Changing the infusion rate of intravenous fluid (Choice A) requires a physician's order and is not an independent nursing intervention. Encouraging the client to discuss feelings (Choice B) is important for emotional support but not as crucial as physical care immediately postoperatively. Administering opioid narcotic medications (Choice C) for pain management should be based on a prescribed schedule and assessment rather than being an independent nursing action.

Correct Answer: C

Rationale: Patients taking anticoagulants should be cautious about consuming high-vitamin K foods. Vitamin K can interfere with the effectiveness of anticoagulants by affecting blood clotting. Choices A, B, and D are incorrect because they do not directly interact with the action of anticoagulants.

Correct Answer: B

Rationale: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries. Choices A, C, and D are incorrect. Hyperthyroidism, underweight, and poor appetite do not directly cause atherosclerosis. Similarly, constipation, peptic ulcer disease, pancreatitis, kidney failure, edema, and sodium retention are not among the primary causes of atherosclerosis.

Correct Answer: B

Rationale: In cases of food poisoning, a 2-year-old with reduced urine output is a critical finding indicating dehydration, requiring immediate attention to prevent complications. The reduced urine output is a sign of decreased fluid intake or increased fluid loss, putting the child at high risk for dehydration. This client should be seen first to assess hydration status, initiate necessary interventions, and prevent further complications. While the other symptoms presented by the other clients are concerning, the 2-year-old's decreased urine output poses the most immediate threat to their well-being.
