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 B

Explanation

Metformin is a medication that can aﬀect kidney function. Since contrast dye used in CT scans is processed through the kidneys, it is important for the nurse to follow up on the client’s use of metformin before the CT scan with contrast. The client may need to temporarily stop taking metformin before and after the procedure to prevent any potential harm to their kidneys.

A. Reported history of alcoholism. B. Toenails appear thick and yellow. C. White blood cells count of 8,500/mm3 or 85 x 109 /L (SI). D. Employed as a construction worker.

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.
