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?
Check for changes in vision.
Monitor the client's hearing.
Observe the skin for a rash.
Measure the urinary output.
The Correct Answer is B
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

Correct Answer is C
Explanation
Choice A rationale: While monitoring temperature is important for a client with meningitis to track the resolution of infection, it is not a prerequisite for administering penicillin. It does not prevent life-threatening complications.
Choice B rationale: Assessing the level of consciousness is a critical part of the neurological assessment for meningitis. However, it is not the specific priority action required before administering a first dose of an antibiotic.
Choice C rationale: Penicillin carries a high risk of anaphylaxis. The nurse must verify the client's allergy history to ensure safety, as a previous reaction to penicillin or cephalosporins could lead to a fatal allergic response.
Choice D rationale: While cultures must be obtained before starting antibiotics, this question specifies the provider has already ordered the medication for an identified organism (Streptococcus pneumoniae), implying the diagnostic cultures have already been completed.
Correct Answer is B
Explanation
Choice A rationale:
This statement is incorrect. Antihypertensive drugs typically work by reducing blood pressure through various mechanisms, such as dilating blood vessels, reducing blood volume, or affecting the heart's workload. They do not increase blood flow to the heart and kidneys.
Choice B rationale:
This is the correct answer. Antihypertensive drugs work by affecting different aspects of the cardiovascular system, such as reducing blood vessel constriction (vasodilation), decreasing blood volume, or slowing the heart rate. By affecting these components, they can lower blood pressure.
Choice C rationale:
This statement is incorrect. Antihypertensive drugs can interact with other medications or supplements, potentially causing adverse effects or drug interactions. It's essential for the client to inform their healthcare provider of all medications and supplements they are taking to ensure safe and effective treatment.
Choice D rationale:
This statement is incorrect. Antihypertensive drugs do not cure hypertension but help control it. Clients need to understand that they will likely need to take these medications long-term to manage their blood pressure effectively.
