Correct Answer: B

Rationale: The correct action the nurse should include in the plan of care when caring for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is crucial to monitor for any signs of bleeding or complications at the access site. Withholding all medications until after dialysis (Choice A) is not necessary unless specified for certain medications. Rehydrating with dextrose 5% in water for hypotension (Choice C) is not appropriate for addressing hypotension related to hemodialysis. Giving an antibiotic 30 minutes before dialysis (Choice D) is not typically indicated unless there is a specific medical indication for prophylactic antibiotic use.

Correct Answer: B

Rationale: The correct answer is to wear gloves to apply the patch to the client's skin. This action ensures that the nurse does not absorb any medication through their own skin, promoting safety. Choice A is incorrect because shaving is not necessary and could irritate the skin. Choice C is incorrect because transdermal patches should be applied immediately after removal from the protective pouch to maintain their efficacy. Choice D is incorrect because used patches should be folded and discarded safely according to facility protocols.

Correct Answer: D

Rationale: The correct answer is D. An elevated WBC count can indicate a potential infection, especially in a postoperative client. This finding should be reported to the provider for further evaluation and management. Choices A, B, and C are common occurrences in postoperative clients and may not necessarily indicate a severe issue. Serosanguineous drainage on the surgical dressing is a normal finding in the immediate postoperative period. A temperature of 37.8°C (100°F) can be a mild fever, which is common postoperatively due to the body's response to tissue injury. Urine output of 75 mL in the past 4 hours may be within normal limits for a postoperative client, especially if they are still recovering from anesthesia.

Correct Answer: D

Rationale: The correct answer is D because enoxaparin should be injected into the abdomen to ensure proper absorption. Choice A is incorrect as enoxaparin should not be taken with food. Choice B is incorrect as enoxaparin should be injected subcutaneously, not into the muscle. Choice C is incorrect as massaging the injection site after administering enoxaparin is not recommended.

Correct Answer: D

Rationale: The correct statement to include in the teaching about PCA is that the client can adjust the amount of pain medication they receive by pushing on the keypad. This empowers the client to control their pain management effectively. Choice A is incorrect because PCA systems are programmed to prevent double dosing when the button is pressed multiple times in quick succession. Choice B is incorrect as continuous PCA infusion aims to maintain a steady plasma medication level. Choice C is incorrect because it is not necessary to push the button before physical activity to ensure maximum pain control; the client should use the PCA as needed for pain relief.
