A male client has been receiving the antibiotic gentamicin sulfate IV piggyback every 12 hours for several days. Which observations by the nurse indicate that the client may be experiencing an adverse eﬀect of gentamicin?

Hearing has decreased.

Decreased blood urea nitrogen.

White blood cells count 6,000/mm3 (6x109/L).

Reports of photophobia.

Answer and Explanation

The Correct Answer is A

Gentamicin sulfate is an aminoglycoside antibiotic that can cause ototoxicity, which is damage to the inner ear leading to hearing loss or balance problems. Therefore, a decrease in hearing is an indication that the client may be experiencing an adverse eﬀect of gentamicin.

Option b, decreased blood urea nitrogen, is not an adverse eﬀect of gentamicin, but it may indicate improvement in kidney function, which can be a positive outcome of treatment.

Option c, a white blood cell count of 6,000/mm3 (6x109/L), is within the normal range and is not necessarily an adverse eﬀect of gentamicin.

Option d, photophobia, is not a common adverse eﬀect of gentamicin and may indicate a diﬀerent condition or medication eﬀect.

Correct Answer is A

Explanation

Terbinafine HCL is primarily metabolized by the liver, and a history of alcoholism may indicate liver dysfunction or damage, which could aﬀect the metabolism and clearance of the drug. The nurse should assess the client's liver function, including liver enzymes, bilirubin levels, and albumin levels, before administering terbinafine HCL.

While options b, c, and d may be important assessment findings, they are not as crucial as a history of alcoholism when it comes to administering terbinafine HCL.

The thick and yellow toenails (option b) are typical symptoms of a fungal toenail infection, which is the reason for prescribing terbinafine HCL.

The white blood cell count (option c) is within normal range.

Being employed as a construction worker (option d) does not have a direct impact on the use of terbinafine HCL.

A. Decreases pain during urination. B. Increases strength of the urine system. C. Promotes excretion of uric acid in the urine. D. Prevents formation of kidney stones.

Correct Answer is C

Explanation

Probenecid is a uricosuric drug that works by inhibiting the reabsorption of uric acid in the kidneys and promotes its excretion in the urine. This drug is used to treat gout and hyperuricemia (high levels of uric acid in the blood). Therefore, the nurse should explain to the client that the purpose of probenecid is to promote the excretion of uric acid in the urine and lower the levels of uric acid in the blood, which can help prevent gout attacks and kidney stones.

Options a, b, and d are incorrect as they do not accurately describe the mechanism of action or purpose of probenecid.
