Question

Furosemide (Tobramycin is an amino-glycoside antibiotic that can cause ototoxicity. Furosemide is a diuretic that also can cause ototoxicity. The client's risk for hearing loss is increased if receiving both of these medications at the same time.)

a) to enhance diuretic effects
b) to reduce fluid intake
c) to prevent ototoxicity
d) an increased risk for hearing loss

Answer 1

Loop diuretics like furosemide increase urination by inhibiting the reabsorption of Na+ and Cl- ions in the loop of Henle. When taken with aminoglycoside antibiotics, there is an increased risk for hearing loss due to the ototoxicity of both medications.

Step-by-step explanation:

The primary topic of this question is medicine.

Loop diuretics, such as furosemide, are medications that inhibit the reabsorption of sodium (Na+) and chloride (Cl-) ions in the ascending limb of the loop of Henle in the nephron. This inhibition causes an increase in the excretion of these ions, leading to increased urine production. The increased urine production is the reason why loop diuretics, including furosemide, can cause increased frequency of urination as a side effect.

When furosemide is taken together with aminoglycoside antibiotics like tobramycin, there is an increased risk for hearing loss. Both furosemide and tobramycin have ototoxic properties, which means they can cause damage to the ear and lead to hearing loss. Therefore, the client's risk for hearing loss is increased if receiving both of these medications at the same time.
