Correct Answer: A

Rationale: The correct answer is A. Furosemide (Lasix) is a loop diuretic used to manage fluid overload and hypertension in clients with CKD. Monitoring daily weights is crucial as weight changes reflect fluid status. Each kilogram of weight change approximately corresponds to 1 liter of fluid retention or loss, making it essential for evaluating the medication's effectiveness. Auscultating heart and breath sounds is more relevant for heart failure cases with fluid retention, not specifically for assessing the effect of furosemide in CKD. Palpating the abdomen is not a direct indicator of furosemide's effectiveness; instead, assessing for edema would be appropriate. While assessing the client's diet history is important to monitor electrolyte balance due to potassium loss with furosemide, it does not directly evaluate the medication's efficacy.

Correct Answer: D

Rationale: After a cystoscopy, the nurse should monitor urine output and promptly contact the provider if there is a decrease or absence of urine output. Additionally, the nurse should assess for blood in the urine. While some pink-tinged urine may be expected, the presence of gross bleeding or blood clots warrants immediate provider notification. Tolerating oral fluids is a positive sign and does not require urgent intervention. Metformin would be a concern if the client received contrast dye, which is not used in a cystoscopy. A burning sensation when urinating is a common post-procedure experience and does not necessitate contacting the provider. Therefore, choices A and B are the correct answers as they indicate potentially serious complications that require immediate attention, while choices C and D do not align with urgent concerns following a cystoscopy.

Correct Answer: B

Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.

Correct Answer: B

Rationale: The correct answer is B: To decrease bacterial resistance. Trimethoprim-sulfamethoxazole (TMP-SMX) is a combination drug used to prevent bacterial resistance to sulfonamides. It works by targeting different steps in the bacterial metabolic pathway, making it harder for bacteria to develop resistance. Choice A is incorrect because the combination does not broaden the antibacterial spectrum; instead, it enhances effectiveness against specific bacteria. Choice C is incorrect as taste improvement is not the primary reason for combining these drugs. Choice D is incorrect because while combination therapy can sometimes help minimize toxic effects, the primary purpose in this case is to address bacterial resistance.

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.
