Correct Answer: B

Rationale: The correct pre-procedure instruction the nurse should provide to a client with chronic kidney disease (CKD) scheduled for a renal biopsy is to avoid taking anticoagulant medications for one week before the biopsy. This instruction is crucial to reduce the risk of bleeding during the procedure, as anticoagulants can increase the chance of bleeding complications. Choices A, C, and D are incorrect because maintaining a low-protein diet, drinking plenty of fluids, or taking routine medications with water are not specifically related to reducing the risk of bleeding associated with a renal biopsy in a client with CKD.

Correct Answer: C

Rationale: Correctly trimming toenails straight across is crucial in preventing ingrown toenails and potential infections in individuals with diabetes. Ingrown toenails can lead to complications, so it is essential for diabetic clients to practice proper nail care to avoid these issues. Choices A, B, and D are incorrect. Walking barefoot can increase the risk of foot injuries, soaking feet in hot water can cause burns or skin damage, and using a heating pad can lead to burns or injuries due to decreased sensation in the feet, which is common in diabetes.

Correct Answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.

Correct Answer: D

Rationale: The correct answer is D: Hyperglycemia. Risperidone (Risperdal) can lead to metabolic side effects, such as hyperglycemia, which requires monitoring. Choice A, Hypertension, is incorrect because risperidone is not typically associated with hypertension. Choice B, Weight loss, is less common with risperidone use as it can lead to weight gain. Choice C, Hyperactivity, is not a common side effect of risperidone; instead, it is more known for sedative effects.

Correct Answer: C

Rationale: Epoetin alfa is a medication that stimulates red blood cell production. Therefore, in a client with chronic renal failure, an effective outcome of epoetin alfa therapy would be an improvement in hemoglobin levels. This indicates that the medication is working as intended by addressing anemia, a common complication of chronic renal failure. Increased urine output (choice A) is not directly related to the action of epoetin alfa. Decreased blood pressure (choice B) is not a primary expected outcome of epoetin alfa therapy. Stable potassium levels (choice D) are important but not a direct indicator of the effectiveness of epoetin alfa in this context.
