The parents of a one-year-old child with the diagnosis of hypospadias informed the practical nurse (PN) that they plan to delay corrective surgery to see if the child will outgrow the problem. Which information should the PN provide to these parents?

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

The correct answer is Choice D.

Choice A rationale: Moving Client D into an isolation room 24 hours before surgery is not necessary. The client’s white blood cell (WBC) count is 14,000 mm (14 x 10^9/L), which is higher than the normal range of 5000 to 10,000/mm² (5 to 10 x 10^9/L). This indicates that the client may have an infection. However, it is not standard practice to isolate clients scheduled for surgery based solely on an elevated WBC count. Other factors, such as the presence of specific infectious diseases, would dictate the need for isolation.

Choice B rationale: Asking the dietitian to add a banana to Client C’s breakfast tray is not necessary. The client’s potassium level is 3.8 mEq/L (3.8 mmol/L), which is within the normal range of 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). Therefore, there is no need to increase the client’s potassium intake.

Choice C rationale: Increasing Client A’s oxygen to 4 liters a minute per cannula is not necessary. The client has emphysema and their oxygen saturation is 94%, which is within the normal range. Increasing the oxygen flow rate could lead to oxygen toxicity or suppress the client’s respiratory drive, leading to respiratory depression or failure.

Choice D rationale: Verifying that Client B has two units of packed cells available is the correct intervention. The client’s postoperative hemoglobin level is 8.2 mg/dL (82 g/L), which is lower than the normal range of 14 to 18 g/dL (140 to 180 g/L). This indicates that the client is anemic and may require a blood transfusion. Therefore, it is important to ensure that packed cells are available if needed.
