Correct Answer is ["A","B"]

Explanation

Gentamicin is an aminoglycoside antibiotic that can causeototoxicity(damage to the inner ear) andnephrotoxicity(damage to the kidneys) as serious side effects. These effects may be irreversible and can occur even at therapeutic doses. Therefore, the nurse should monitor the client’s hearing, balance, urine output, and blood tests for kidney function while on this drug.

Choice C is wrong because gentamicin does not causehepatotoxicity(damage to the liver).

This is more common with other antibiotics such as isoniazid or rifampin.

Choice D is wrong because gentamicin does not causeneuromuscular blockade(paralysis of muscles).

This is more common with other aminoglycosides such as neomycin or tobramycin.

Choice E is wrong because gentamicin does not causethrombocytopenia(low platelet count).

This is more common with other drugs such as heparin or sulfonamides.

A. Jaundice B. Vision changes C. Hearing loss D. Orange-colored urine E. Numbness in the hands or feet.

Correct Answer is ["A","B","E"]

Explanation

Jaundice, vision changes and numbness in the hands or feet are possible adverse effects of the drugs used to treat tuberculosis.The nurse should instruct the client to report these signs or symptoms as they may indicate liver damage, optic neuritis or peripheral neuropathy respectively.

Choice C is wrong because hearing loss is not a common side effect of these drugs.Hearing loss may be caused by other drugs such as aminoglycosides.

Choice D is wrong because orange-colored urine is a harmless side effect of rifampin and does not need to be reported.

The nurse should inform the client about this expected change and reassure them that it is not harmful.

The normal ranges for liver function tests are:

• AST: 10-40 U/L

• ALT: 7-56 U/L

• ALP: 45-115 U/L

• Bilirubin: 0.1-1.2 mg/dL

The normal range for visual acuity is 20/20.

The normal range for sensation is intact and symmetrical in all extremities.
