What medications are associated with causing hyperkalemia in enterally fed patients?

The medications that are specifically associated with causing hyperkalemia in enterally fed patients are primarily potassium-sparing diuretics like spironolactone and medications such as Penicillin G Potassium, which can contribute to elevated potassium levels.

Spironolactone acts as an aldosterone antagonist, preventing the excretion of potassium in the urine, which can lead to accumulation of potassium in the bloodstream, particularly in patients with kidney dysfunction or when potassium intake is increased through enteral feeding. Penicillin G Potassium, when administered, provides additional potassium to the patient and could result in hyperkalemia, especially when dietary potassium is already high or renal function is compromised.

In contrast, acetaminophen and MAOIs do not have a significant impact on potassium levels and are not linked to hyperkalemia in enterally fed patients. Propranolol and barbiturates also do not cause hyperkalemia. Therefore, the correct response is focused on the specific interactions and impacts of spironolactone and penicillin G potassium regarding potassium levels in enterally fed patients.
