1. The healthcare professional is preparing to give a dose of trimethoprim-sulfamethoxazole (TMP-SMX) and learns that the patient takes warfarin (Coumadin). The healthcare professional will request an order for

Correct answer: D

Rationale: Sulfonamides, like trimethoprim-sulfamethoxazole (TMP-SMX), can potentiate the anticoagulant effects of warfarin (Coumadin). To monitor the patient's response and prevent adverse effects, the healthcare professional should request coagulation studies, such as International Normalized Ratio (INR) levels. Choosing a decreased dose of TMP-SMX would not address the potential drug interaction between TMP-SMX and warfarin. Opting for a different antibiotic is not necessary if the interaction can be managed by monitoring. Increasing the dose of warfarin without monitoring could lead to excessive anticoagulation and adverse events, so it's not the appropriate action in this scenario.

2. The client with diabetes mellitus is being taught how to prevent or delay chronic kidney disease (CKD). Which client statements indicate a lack of understanding of the teaching? (Select all that apply.)

Correct answer: D

Rationale: The correct answer is D. Both statements A and B indicate a lack of understanding of CKD prevention. Taking aspirin every 4 to 8 hours can lead to kidney damage, and maintaining a body mass index (BMI) of 30 is considered overweight, which can increase the risk of developing CKD. Statement C, on the other hand, correctly addresses smoking cessation, which is crucial in preventing CKD. Therefore, choices A and B are incorrect as they do not align with CKD prevention strategies, making option D the correct choice.

3. The client with chronic renal failure is being educated about the importance of a low-sodium diet. Which of the following statements by the client indicates a need for further teaching?

Correct answer: B

Rationale: The correct answer is B. Clients with chronic renal failure need to strictly limit their sodium intake. Advising the client to use table salt sparingly is incorrect as they should avoid table salt altogether to adhere to a low-sodium diet. Choice A is correct as rinsing canned vegetables can help reduce their sodium content. Choice C is correct as consuming frozen dinners labeled low-sodium can be a suitable option. Choice D is incorrect as it implies that avoiding only salty foods is sufficient, when in fact, overall sodium intake needs to be monitored closely.

4. A nurse assesses a client who is recovering from a radical nephrectomy for renal cell carcinoma. The nurse notes that the client’s blood pressure has decreased from 134/90 to 100/56 mm Hg and urine output is 20 mL for this past hour. Which action should the nurse take?

Correct answer: D

Rationale: The nurse should first fully assess the client for signs of volume depletion and shock, and then notify the provider. The radical nature of the surgery and the proximity of the surgery to the adrenal gland put the client at risk for hemorrhage and adrenal insufficiency. Hypotension is a clinical manifestation associated with both hemorrhage and adrenal insufficiency. Hypotension is particularly dangerous for the remaining kidney, which must receive adequate perfusion to function effectively. Re-positioning the client, measuring specific gravity, and administering pain medication would not provide data necessary to make an appropriate clinical decision, nor are they appropriate interventions at this time.

5. The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?

Correct answer: C

Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.
