Final answer:
A diuretic is the medication typically prescribed to remove excess fluid from the lungs, as it helps increase urine output and reduce fluid retention in the body.
Step-by-step explanation:
Of the mentioned medications, the one typically ordered to help a patient get rid of excess fluid in their lungs is a diuretic. Diuretics are compounds that increase urine output and therefore decrease water conservation by the body. These medications are used not only for conditions like congestive heart failure but also for the treatment of hypertension and to reduce fluid retention associated with other medical conditions. Loop diuretics in particular work by inhibiting the reabsorption of Na+ and Cl- ions in the loop of Henle in the nephron, leading to an increase in urine volume and the elimination of excess fluid.
By contrast, antacids are used to neutralize stomach acid and would not be relevant for removing fluid from the lungs. Similarly, antibiotics are utilized to combat bacterial infections and would not directly aid in reducing pulmonary fluid accumulation unless the fluid retention was a result of an infection.
