The nurse is caring for a client who is scheduled for hemodialysis. Which of the following laboratory values should the nurse monitor closely before, during, and after the procedure?

Correct Answer: D

Rationale: The correct answer is D: Serum potassium level. Before, during, and after hemodialysis, monitoring the serum potassium level is crucial to prevent hyperkalemia, a potentially life-threatening complication. Hemodialysis is done to remove waste products and excess electrolytes like potassium from the blood. Monitoring other laboratory values like hemoglobin, BUN, and creatinine is important in assessing kidney function and anemia, but serum potassium level requires close monitoring during hemodialysis due to the risk of rapid shifts that can lead to cardiac arrhythmias.

Correct Answer: B

Rationale: The correct answer is B. Weight gain of 2 lbs (0.9 kg) since the last treatment is concerning in a client undergoing hemodialysis with chronic renal failure as it may indicate fluid overload. This finding requires immediate reporting and intervention to prevent complications such as fluid retention, pulmonary edema, or exacerbation of heart failure. Choices A, C, and D are not findings that require immediate attention in this context. Clear dialysate outflow is a normal finding during hemodialysis, a blood pressure of 130/80 mm Hg is within a normal range for many clients, and a pulse rate of 72 bpm is also within the expected range for most individuals.

Correct Answer: C

Rationale: The correct answer is C: Hyperkalemia. Sodium polystyrene sulfonate (Kayexalate) is used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the large intestine, which is then eliminated through the feces. Therefore, the nurse should monitor the client for changes in potassium levels to ensure the effectiveness of the treatment. Choices A, B, and D are incorrect because sodium polystyrene sulfonate (Kayexalate) is not associated with causing hyponatremia, hypokalemia, or hypocalcemia.

Correct Answer: C

Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.

Correct Answer: C

Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.
