Which drugs may cause hypernatremia for enterally fed patients?

The correct choice reflects that Penicillin G Sodium and Normal Saline may contribute to hypernatremia, particularly in patients who are enterally fed. When a patient is receiving enteral nutrition, careful management of electrolytes is crucial because they may be at increased risk for imbalances.

Penicillin G Sodium contains a substantial amount of sodium, which can lead to elevated sodium levels if not appropriately monitored or if the patient has conditions that predispose them to hypernatremia, such as dehydration or certain kidney functions impaired by the enteral feed. Normal Saline, which is isotonic, also contains sodium and can contribute to hypernatremia if there is an over-administration or if the patient has limited renal capacity to excrete sodium effectively.

In contrast, while laxatives and diuretics are associated with electrolyte imbalances, they typically lead to hyponatremia or potassium imbalances rather than hypernatremia. This is primarily due to their mechanisms, which enhance fluid loss and can dilute sodium concentrations. Acetaminophen and MAOIs also do not have a significant direct impact on sodium levels and are generally not associated with causing hypernatremia in enteral feeding situations.

Therefore, the emphasis on sodium-containing medications
