Which of the following intradialytic orders for a patient with pericarditis should the nurse question?

In the scenario involving a patient with pericarditis, questioning the order for heparin at a dosage of 100 units per kilogram is appropriate due to the potential complications associated with anticoagulation in this context. Pericarditis can lead to inflammation of the pericardium, which may contribute to fluid accumulation around the heart, increasing the risk of cardiac tamponade. Administering heparin, an anticoagulant, could pose a risk of exacerbating bleeding, especially if any invasive procedures are necessary or if there are underlying concerns of bleeding in the patient.

For patients with pericarditis, careful management of any anticoagulant therapy is essential to avoid further cardiovascular complications. Other orders, such as fluid replacement, monitoring vital signs, and administering antihypertensives, are generally more aligned with managing the patient’s condition and the effects of dialysis, especially if they are dealing with fluid overload or blood pressure regulation. Each of these orders contributes positively to monitoring and managing the patient's health without adding the risks associated with excessive anticoagulation.
