Correct Answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease should limit their intake of phosphorus because high phosphorus levels can lead to bone disease and cardiovascular problems. Increasing foods high in potassium (choice B) is not recommended as it can be harmful to individuals with kidney disease. Decreasing intake of foods high in iron (choice C) is not specifically indicated for chronic kidney disease. Increasing calcium supplements (choice D) may not be necessary and can potentially lead to hypercalcemia in individuals with kidney disease.

Correct Answer: A

Rationale: The correct answer is A. Ibuprofen can increase the risk of bleeding when taken with warfarin, as both medications affect clotting. The client should use alternative pain relievers like acetaminophen. Choice B is correct as using an electric razor is a safe choice to prevent cuts that could lead to bleeding. Choice C is correct as warfarin interacts with vitamin K found in leafy green vegetables. Choice D is correct as regular blood level checks are necessary to monitor the effects and adjust the warfarin dosage if needed.

Correct Answer: B

Rationale: Using dedicated equipment for a neutropenic client, such as a stethoscope, helps prevent infections. Neutropenic clients have a weakened immune system, making them vulnerable to infections from common pathogens. Wearing an N95 respirator is not necessary unless airborne precautions are required. Inserting a urinary catheter should be avoided unless necessary to prevent introducing pathogens. Monitoring vital signs should be done more frequently, typically every 4 hours, to promptly identify any changes in the client's condition.

Correct Answer: C

Rationale: The correct answer is C. Clients taking lisinopril should avoid potassium-rich foods because ACE inhibitors can increase potassium levels, potentially leading to hyperkalemia. Choices A, B, and D are all correct statements. Clients should notify their doctor if they develop a cough as it can indicate a potential side effect of lisinopril. Avoiding salt substitutes is important as they may contain potassium chloride, which can also raise potassium levels. Monitoring blood pressure regularly is essential when taking an antihypertensive medication like lisinopril.
