Which of the following medications may cause hypokalaemia in enterally fed patients?

Hypokalaemia, or low potassium levels in the blood, can be influenced by various medications, especially in patients who are enterally fed. Each of the listed options can contribute to this condition in different ways.

Insulin can drive potassium into cells, leading to a decrease in serum potassium levels. This effect is particularly important in patients who are already at risk of hypokalaemia due to inadequate potassium intake in an enteral nutrition regimen.

Diuretics, especially thiazide and loop diuretics, are well-known for their ability to increase potassium excretion through the kidneys. When patients are receiving enteral nutrition, which may not provide adequate potassium, the use of these diuretics can result in significant potassium depletion.

Antibiotics, while not traditionally linked to hypokalaemia, may disrupt the gut flora and influence potassium absorption or increase the risk of diarrhea, which can lead to losses of potassium.

Because all these medications — insulin, diuretics, and antibiotics — have mechanisms that could lead to hypokalaemia, it is accurate to conclude that each can contribute to this electrolyte imbalance in enterally fed patients. Thus, the answer reflects that all the medications listed can potentially cause low potassium levels, emphasizing the
