Correct Answer: B

Rationale: The correct action the healthcare provider should include is changing the TPN tubing every 24 hours to decrease the risk of infection. Administering 0.9% sodium chloride with TPN is not typically recommended as it can cause chemical instability. Weighing the client every 72 hours is important but not directly related to TPN administration. Flushing the TPN line with heparin is not a standard practice and not recommended as it can increase the risk of complications.

Correct Answer: C

Rationale: The correct action for the nurse to take when preparing to administer IV medication to a client with a latex allergy is to administer the medication through a latex-free IV port. This is crucial as it prevents direct contact of the medication with latex, reducing the risk of an allergic reaction. Choice A is incorrect as using latex gloves can still expose the client to latex. Choice B is not the best option since the administration route is not specified, and using a latex-free syringe alone may not be sufficient to prevent exposure. Choice D is not the most appropriate because the IV tubing and ports should also be latex-free to ensure complete avoidance of latex contact.

Correct Answer: A

Rationale: The correct answer is A. Warfarin is an anticoagulant that increases the risk of bleeding during surgery. It is crucial for the provider to be informed about the client taking warfarin to adjust the treatment plan accordingly. Choices B, C, and D are not as critical to report for surgical planning. A history of hypertension (B) is important but may not require immediate intervention for surgery. Eating a light breakfast 2 hours prior (C) is a normal preoperative instruction. Smoking history (D) is relevant for overall health assessment but is not as urgent as the use of warfarin before surgery.

Correct Answer: A

Rationale: The correct answer is A: "I will avoid aspirin while taking this medication." Clients taking warfarin should avoid aspirin due to the increased risk of bleeding. Choice B is incorrect because increasing the intake of green leafy vegetables high in Vitamin K can interfere with the effects of warfarin. Choice C is incorrect because warfarin should not be taken with antacids as they can decrease its absorption. Choice D is incorrect because mild bruising is a common side effect of warfarin due to its anticoagulant properties.

Correct Answer: D

Rationale: In this scenario, the nurse should anticipate initiating continuous bladder irrigation. Dark yellow urine output at a rate of 25 ml/hr following abdominal surgery may indicate urinary stasis or obstruction, which could lead to complications like urinary retention. Continuous bladder irrigation helps prevent catheter obstruction and manage urinary retention by ensuring patency and promoting urine flow. Clamping the catheter (Choice A) could lead to urinary stasis and should be avoided. Administering a fluid bolus (Choice B) is not indicated solely based on the urine color and output described. Obtaining a urine specimen for culture and sensitivity (Choice C) may be necessary for assessing infection but does not directly address the issue of urinary stasis or obstruction.
