Correct Answer: B

Rationale: The correct answer is B: Fluid overload. Clients with chronic kidney disease are prone to fluid overload due to impaired kidney function. The kidneys may not effectively regulate fluid balance, leading to fluid retention. Monitoring for signs of fluid overload, such as edema, hypertension, and shortness of breath, is crucial. Choice A, Hypokalemia, is less likely in chronic kidney disease as the kidneys often have difficulty excreting potassium, leading to hyperkalemia. Decreased blood pressure (Choice C) is not a common finding in chronic kidney disease unless complications like volume depletion occur. Increased appetite (Choice D) is not typically associated with chronic kidney disease; in fact, many clients may experience a decreased appetite due to various factors such as uremia and dietary restrictions.

Correct Answer: B

Rationale: The correct answer is B: Macule. A macule is a non-palpable skin lesion smaller than 1 cm in diameter. In this case, the skin lesion described is less than 0.5 cm, making it consistent with a macule. Vesicle (choice A) is a small blister filled with clear fluid, papule (choice C) is a solid, raised skin lesion less than 0.5 cm in diameter, and nodule (choice D) is a palpable, solid lesion larger than 0.5 cm in diameter. Therefore, choices A, C, and D describe skin lesions that do not match the characteristics of the lesion presented in the question.

Correct Answer: C

Rationale: The correct answer is to advise the client to avoid potassium supplements. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Adding potassium supplements on top of this medication can lead to hyperkalemia, an elevated level of potassium in the blood, which can be dangerous. Choices A, B, and D are incorrect because increasing potassium-rich foods, limiting sodium intake, and increasing protein intake are not specifically related to the dietary considerations when taking spironolactone.

Correct Answer: B

Rationale: Dry mucous membranes are a classic sign of dehydration. In dehydration, the body loses more water than it takes in, leading to dryness of mucous membranes like the mouth and throat. Edema (choice A) is swelling caused by excess fluid trapped in the body's tissues, which is not a typical sign of dehydration. Weight gain (choice C) is also not a common sign of dehydration; in fact, dehydration usually leads to weight loss. Increased urination (choice D) is more indicative of conditions like diabetes or diuretic use, not dehydration.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid alcohol while taking this medication.' Metronidazole can cause a disulfiram-like reaction with alcohol, leading to symptoms like nausea, vomiting, flushing, and headache. Therefore, clients should be instructed to avoid alcohol consumption. Choice B is incorrect because metronidazole is not considered safe during pregnancy, especially in the first trimester. Choice C is incorrect as metronidazole is not known to cause increased appetite. Choice D is also incorrect as hair loss is not a common side effect of metronidazole.
