Correct Answer: D

Rationale: The correct answer is D, Spironolactone. Spironolactone is a potassium-sparing diuretic, which may lead to hyperkalemia in clients with chronic kidney disease. Therefore, its use should be questioned in this population. Choice A, Calcium carbonate, is commonly used to manage phosphate levels in chronic kidney disease. Choice B, Furosemide, is a loop diuretic that helps with fluid retention but should be used with caution in kidney disease. Choice C, Epoetin alfa, is a medication used to stimulate red blood cell production in clients with chronic kidney disease and anemia.

Correct Answer: A

Rationale: The correct answer is to apply a hydrocolloid dressing. Stage 3 pressure ulcers are characterized by full-thickness skin loss involving damage to or necrosis of subcutaneous tissue, which requires a moist environment for healing. Hydrocolloid dressings help maintain a moist wound environment, promote healing, and provide protection. Providing wound debridement may be necessary but is not the priority intervention at this stage. Changing the dressing daily is important for wound care but not the priority over creating an optimal healing environment. Elevating the affected area can help with circulation and reduce swelling, but it is not the priority intervention for a stage 3 pressure ulcer.

Correct Answer: C

Rationale: The correct answer is Hypokalemia (Choice C). Loop diuretics can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is a common concern with loop diuretic therapy and necessitates regular monitoring. Hyperkalemia (Choice A) is not typically associated with loop diuretics but with conditions like renal failure. Hyponatremia (Choice B) is more common with thiazide diuretics. Hypercalcemia (Choice D) is not a typical concern with loop diuretic use.

Correct Answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

Correct Answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.
