Correct Answer is C

Explanation

A. Administer scheduled medications: Some medications (e.g., antihypertensives, water-soluble vitamins, and antibiotics) should be held before dialysis to prevent removal during treatment.

B. Explain that dialysis occurs via the peritoneum: This describes peritoneal dialysis, not hemodialysis.

C. Weigh the client to determine a baseline for comparison: Pre-dialysis weight is crucial to determine fluid removal needs during dialysis. Weight differences before and after dialysis indicate fluid loss or retention.

D. Obtain a serum creatinine to determine kidney function: Serum creatinine levels are monitored regularly but are not a required step before every dialysis session.

A. Request a neurological consult B. Have another nurse take their blood pressure C. Review the client's lab values. D. call the healthcare provider for orders.

Correct Answer is C

Explanation

A. Request a neurological consult: This is likely a metabolic issue (hypocalcemia), not a neurological disorder.

B. Have another nurse take their blood pressure: Rechecking BP does not address the underlying cause of the abnormal movement.

C. Review the client's lab values: Carpopedal spasm (Trousseau's sign) during BP measurement suggests hypocalcemia. The nurse should check serum calcium levels to confirm.

D. Call the healthcare provider for orders: The nurse should first review lab results to provide accurate data when notifying the provider.
