A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

Correct Answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

Correct Answer: A

Rationale: The nurse should document the time the medication was given in the client's medical record when an incorrect dose is administered. Recording the time is crucial for establishing the sequence of events accurately. Choices B, C, and D, though important, are not directly relevant to documenting the incident of administering an incorrect dose of medication. The client's response to the medication, the actual dose administered, and the reason for the error may be documented for overall patient care but are not specifically required in the incident report for an incorrect dose.

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.

Correct Answer: C

Rationale: The correct answer is to monitor potassium levels when a patient is receiving furosemide because furosemide can cause potassium depletion. It is essential to monitor potassium levels to prevent complications such as hypokalemia. While monitoring urine output is important in assessing kidney function, and monitoring blood pressure and serum creatinine are relevant in certain situations, the priority when administering furosemide is to monitor potassium levels due to the medication's potential to deplete potassium.

Correct Answer: B

Rationale: When caring for a patient with a central line, monitoring for infection is a crucial nursing responsibility. This is essential to prevent complications such as bloodstream infections. While flushing the line with saline and monitoring fluid balance are important aspects of care, they are not as critical as monitoring for infection. Replacing the central line is only done when necessary due to complications or at the end of its recommended use.
