Correct Answer: B

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to place the tablet under the tongue and let it dissolve completely. This route of administration allows for rapid absorption of the medication through the oral mucosa, providing quick relief for angina symptoms. Option A, taking the medication with food, is incorrect as nitroglycerin should be taken sublingually, not with food. Option C, swallowing the tablet whole with water, is incorrect as sublingual tablets should not be swallowed whole. Option D, chewing the tablet for faster relief, is also incorrect as chewing the tablet can lead to rapid absorption and potential adverse effects rather than a controlled release for angina relief.

Correct Answer: A

Rationale: The correct answer is A. Listening to music is a non-pharmacological method to help manage mild pain, reflecting an understanding of pain management strategies. It shows the client's grasp of non-pharmacological pain management techniques taught preoperatively. Choice B, while important, only addresses pharmacological pain management, omitting other strategies discussed in preoperative teaching. Choice C jumps to changing medications without considering non-pharmacological methods first, indicating a narrow approach to pain management. Choice D involves a physical therapist, which is not directly related to the pain management strategies typically discussed in preoperative teaching.

Correct Answer: B

Rationale: The correct answer is B. When providing background information in a shift report using the SBAR communication tool, the nurse should include details related to medication administration and orders. This helps ensure continuity of care and accurate handover of responsibilities. Choices A, C, and D do not typically fall under background information for shift reports. A blood pressure reading, pain rating, and code status are more relevant to the patient's current condition and status, rather than background information about medications or orders.

Correct Answer: D

Rationale: The correct answer is to change the administration set every 72 to 96 hours. This practice helps reduce the risk of infection by preventing the build-up of bacteria in the tubing. Changing the set too frequently (choices A, B, and C) may increase the chances of contamination and infection without providing additional benefits. Therefore, the LPN should follow the guideline of changing the administration set every 72 to 96 hours to maintain the client's safety during the continuous intravenous normal saline infusion.

Correct Answer: A

Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.
