The client with chronic renal failure is scheduled for hemodialysis at 9 am. They are scheduled to receive oral daily medications. Which statement best describes when the nurse should administer the medications?

A. The development of malignant hyperthermia: Malignant hyperthermia (MH) is a life-threatening reaction to certain anesthetics (e.g., succinylcholine, halothane). It causes rapid muscle breakdown, severe hyperthermia, tachycardia, muscle rigidity, and metabolic acidosis. Immediate treatment with IV dantrolene and cooling measures is required.

B. The development of fluid volume excess: Fluid overload may cause hypertension and pulmonary edema but does not cause sudden high fever.

C. The development of an allergic response to the pain medication: Drug allergies typically present with rash, itching, or anaphylaxis, not extreme fever.

D. The development of an infection. Post-op infections usually develop over several days, not immediately in PACU.

A. "We'll find out if any medications, such as steroids, are interfering with your kidney function." Some medications affect kidney function, but creatinine primarily measures kidney efficiency, not drug interactions.

B. "This test will tell your doctor how your kidneys are functioning." Serum creatinine is a key indicator of kidney function. It measures how well the kidneys are filtering waste products.

C. "This test will tell if you have severe renal impairment or disease." Creatinine can be elevated in mild, moderate, or severe kidney dysfunction, not just in severe disease.

D. "You'll have to ask your doctor." The nurse should provide basic health education to the client.
