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 D

Explanation

Intermittent claudication is a condition in which there is pain in the legs due to reduced blood ﬂow. Pentoxifylline is a medication that can improve blood ﬂow by reducing the viscosity of the blood. Therefore, to determine the eﬀectiveness of the medication in managing intermittent claudication, the nurse should monitor the client's pain level using a numeric pain scale. This will help to assess if the medication provides pain relief and improving the client's ability to walk without discomfort.

Options a, b, and c are not relevant to the assessment of the eﬀectiveness of pentoxifylline in managing intermittent claudication.

A. Avoid crowds to help prevent acquiring infections. B. Wear protective padding to protect from bruising if a fall occurs. C. Take measures to avoid dehydration and over-heating. D. Keep skin and eyes covered to protect from sun injury.

Correct Answer is C

Explanation

Oxybutynin is a medicine used to treat symptoms of an overactive bladder. One of the side eﬀects of oxybutynin is that it can cause dry mouth, constipation, and dry skin21. These side eﬀects can increase the risk of dehydration. Additionally, oxybutynin can cause ﬂushing and heat stroke. Therefore, it is important for the client to take measures to avoid dehydration and over-heating while training for a marathon.
