Correct Answer: B

Rationale: The correct answer is to auscultate bowel sounds. This action should be taken first because it ensures that bowel sounds are not altered by physical manipulation. Inspecting the abdomen (choice C) may provide visual cues but does not address functional assessment. Palpating the abdomen (choice A) should follow auscultation to prevent altering bowel sounds. Percussing the abdomen (choice D) is typically done after auscultation and palpation.

Correct Answer: B

Rationale: Postoperative clients are at risk for constipation due to various factors, including decreased fluid intake. Insufficient fluid consumption can lead to hardening of stools, making them difficult to pass. Increased fiber intake (choice A) is actually beneficial for preventing constipation as it adds bulk to the stool. Frequent urge suppression (choice C) can contribute to constipation by disrupting normal bowel habits. Increased physical activity (choice D) generally helps promote bowel movements and reduce the risk of constipation.

Correct Answer: C

Rationale: The correct answer is to identify the client's needs first. This allows the nurse to prioritize interventions based on the assessment findings. Administering prescribed antibiotics (choice A) should be based on a medical prescription and the identified infection. Initiating seizure precautions (choice B) is important but not the immediate priority in this case. Placing the client in isolation (choice D) is premature as the nurse needs to first assess and address the client's condition.

Correct Answer: B

Rationale: The correct action for the nurse to take with the unused portion of a narcotic medication after administration is to discard it with a witness present. This procedure is necessary to comply with controlled substance regulations and prevent diversion or misuse of the medication. Storing it in the medication cart for later use is inappropriate as it can lead to unauthorized access. Returning it to the pharmacy is not recommended as the medication has already been dispensed. Reporting it to the provider is not the standard procedure for disposing of controlled substances.

Correct Answer: B

Rationale: The correct answer is to discontinue the IV infusion. The signs of redness and warmth at the IV site indicate phlebitis, an inflammation of the vein. Discontinuing the IV infusion is crucial to prevent further complications such as infection or thrombosis. Flushing the IV line with saline would not address the underlying issue of phlebitis. Applying a cold compress may provide temporary relief but does not address the cause. Increasing the IV flow rate can exacerbate the inflammation and should be avoided.
