Correct Answer: A

Rationale: In this scenario, the priority intervention is to obtain a urine sample for culture and sensitivity. Older adults with recent falls may have atypical symptoms of urinary tract infection (UTI), which can present as new-onset confusion or falling. It is crucial to rule out UTI before initiating antibiotics. While administering antibiotics, encouraging protein intake, fluids, and consulting physical therapy are important interventions, they should follow the urine sample collection to ensure accurate diagnosis and appropriate treatment.

Correct Answer: C

Rationale: The correct action is to hold the medication and request an order for serum BUN and creatinine. Thiazide diuretics, such as hydrochlorothiazide, are contraindicated in renal failure. In this case, the patient has oliguria, which is a reduced urine output, indicating potential renal insufficiency. Before administering the diuretic, it is crucial to evaluate the patient's renal function through serum BUN and creatinine levels. Encouraging the patient to drink more fluids (Choice B) may not address the underlying issue of renal function. Administering the medication as ordered (Choice A) without assessing renal function can be harmful. Requesting serum electrolytes and administering the medication (Choice D) overlooks the need for a specific evaluation of renal function in this scenario.

Correct Answer: A

Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.

Correct Answer: B

Rationale: Choice B is the correct answer. Clients with PKD often experience constipation, which can be managed by increasing their intake of dietary fiber and fluids. This helps promote bowel regularity. Laxatives should be used cautiously and not as a routine solution. Choice A is incorrect as regular laxative use is not recommended. Choice C is incorrect as a low-salt diet is typically advised for clients with PKD, not just limiting salt while cooking. Choice D is incorrect as white bread is low in fiber and not beneficial for managing constipation, which is common in PKD.

Correct Answer: D

Rationale: Oranges are a rich source of vitamin C, which is essential for wound healing due to its role in collagen synthesis. Citrus fruits like oranges, as well as other fruits and vegetables such as strawberries, kiwi, bell peppers, and broccoli, are high in vitamin C. Meats like steak and veal are not significant sources of vitamin C; they are primarily sources of protein. Cheese is not a good source of vitamin C but does provide calcium and protein.
