The practical nurse (PN) is providing care for a client who is receiving an aminoglycoside to treat a bacterial infection.

To assess for signs of ototoxicity, which action should the PN take?

This is the correct answer because it is the best way to assess for signs of ototoxicity, which is a potential adverse effect of aminoglycosides. Ototoxicity is the damage or injury to the inner ear or auditory nerve caused by certain drugs or chemicals. It can result in hearing loss, tinnitus, vertigo, or balance problems. Aminoglycosides are a class of antibiotics that are effective against gram-negative bacteria, but they can also cause ototoxicity by interfering with the function of the hair cells in the cochlea. The practical nurse (PN) should monitor the client's hearing by asking about any changes in hearing acuity, ringing in the ears, or difficulty understanding speech. The PN should also perform a hearing test using a tuning fork or an audiometer if available. The PN should report any signs of ototoxicity to the health care provider and discontinue the aminoglycoside as ordered.

a) Check for changes in vision.

This is not the correct answer because it is not related to ototoxicity. Vision is the ability to see and perceive objects and colors using the eyes and the brain. Vision may be affected by various factors, such as age, genetics, eye diseases, injuries, infections, or medications. However, aminoglycosides do not cause vision problems or impairments. The PN should check for changes in vision in a client who is receiving other drugs that can cause ocular toxicity, such as ethambutol, chloroquine, or digoxin.

c) Observe the skin for a rash.

This is not the correct answer because it is not related to ototoxicity. A rash is a change in the color, texture, or appearance of the skin that may be caused by various factors, such as allergies, infections, inflammation, or medications. A rash may present as redness, itching, swelling, blisters, bumps, or scales.
Aminoglycosides can cause skin reactions such as rash or urticaria in some clients who are hypersensitive or allergic to them. The PN should observe the skin for a rash in a client who is receiving an aminoglycoside and report any signs of an allergic reaction to the health care provider. However, a rash is not a sign of ototoxicity.

d) Measure the urinary output.

This is not the correct answer because it is not related to ototoxicity. Urinary output is the amount of urine produced and excreted by the kidneys and bladder. It is an indicator of renal function and fluid balance. The normal range for urinary output is 0.5 to 1 mL/kg/hour for adults. Urinary output may be affected by various factors, such as fluid intake, dehydration, diuretics, kidney disease, or medications. Aminoglycosides can cause nephrotoxicity, which is another potential adverse effect of these drugs. Nephrotoxicity is the damage or injury to the kidneys caused by certain drugs or chemicals. It can impair the kidneys' ability to filter waste products from the blood, resulting in reduced urine production and oliguria. The PN should measure the urinary output in a client who is receiving an aminoglycoside and report any signs of nephrotoxicity to the health care provider. However, urinary output is not a sign of ototoxicity

Choice A rationale:

CP being one of the most common permanent physical disabilities in children is a general statement but does not directly address the mother's question about the progression of her child's impaired movements. It does not provide an explanation for the potential course of CP.

Choice B rationale:

Brain damage with CP is not progressive but does have a variable course. This response provides the best explanation to the mother's question. CP is a static neurological condition, which means that the initial brain injury that led to CP does not worsen over time. However, the functional abilities and impairments of a child with CP can vary widely and may change as the child grows and develops. Some children may improve with therapy and interventions, while others may have relatively stable impairments.

Choice C rationale:

Severe motor dysfunction determines the extent of successful habilitation is not entirely accurate. While the severity of motor dysfunction does play a role in the challenges a child with CP may face, it does not solely determine the extent of successful habilitation. Many factors, including early intervention, therapy, and individualized care, can influence a child's progress and potential for improvement.

Choice D rationale:

Continued development of the brain lesion determines the child's outcome is not an accurate statement. CP is primarily caused by non-pro
