Correct Answer: B

Rationale: Verifying tube placement is the priority action the nurse should take before administering enteral feedings. This step ensures that the NG tube is correctly positioned, reducing the risk of complications such as aspiration pneumonia. Flushing the tube with water, elevating the head of the bed, and measuring residual gastric volume are important steps in enteral feeding administration but come after verifying tube placement. Flushing the tube with water helps clear the tubing, elevating the head of the bed reduces the risk of aspiration, and measuring residual gastric volume helps assess the client's tolerance to feedings.

Correct Answer: B

Rationale: When a client reports pain and redness at the site of a peripheral IV, indicating signs of phlebitis, the nurse's initial action should be to discontinue the IV line. This helps prevent further complications and ensures patient safety. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider (Choice C) is important but not the initial step. Increasing the IV flow rate (Choice D) can exacerbate the inflammation and should be avoided.

Correct Answer: B

Rationale: Verifying tube placement is the crucial initial step a nurse should take before administering enteral feedings through an NG tube. This step ensures that the tube is correctly positioned in the stomach, reducing the risk of complications such as aspiration. Measuring residual gastric volume, flushing the tube with water, or administering the feeding in small boluses are all important steps in enteral feeding but should only be done after confirming the correct tube placement.

Correct Answer: B

Rationale: The correct first action for the nurse to take when receiving a report of a client's blood pressure reading of 160/95 is to recheck the blood pressure. Rechecking the blood pressure ensures the accuracy of the reading before making any further decisions or interventions. Notifying the provider (Choice A) can be considered after confirming the blood pressure reading. Administering antihypertensive medication (Choice C) should not be done based solely on one reading without verification. Documenting the blood pressure in the chart (Choice D) should also come after confirming the accuracy of the reading to avoid recording incorrect information.

Correct Answer: C

Rationale: After administering a narcotic medication, any unused portion should be discarded with another nurse as a witness. This procedure ensures proper disposal of controlled substances and prevents misuse or diversion. Storing it for later use (Choice B) is not appropriate due to safety concerns and legal regulations. Returning it to the pharmacy (Choice D) is also not recommended as the medication is already out of the pharmacy's control. Documenting the amount wasted (Choice A) is important for accurate record-keeping but does not address the immediate need for safe disposal of the unused narcotic medication.
