Which of the following may dialysis patients be prescribed on the day of dialysis?

Dialysis patients may be prescribed a short-acting blood thinner like heparin on the day of dialysis due to its specific functionality and timing within the dialysis process. Heparin is commonly used as an anticoagulant during hemodialysis to prevent clotting in the dialysis circuit.

The short-acting nature of heparin is particularly important because it allows for its effects to be easily controlled and reversed, making it suitable for patients undergoing dialysis. After the dialysis session, heparin can be cleared from the body relatively quickly, reducing the risk of bleeding complications post-treatment.

In contrast, long-acting blood thinners would not be appropriate on the day of dialysis, as they could continue to affect coagulation during and after the procedure, leading to an increased risk of bleeding. Antibiotics and muscle relaxants are also not routinely prescribed specifically for the day of dialysis as they do not have the same direct role in managing the dialysis procedure itself and may carry additional risks or interactions in the context of renal function and dialysis treatment.
