A nurse is assessing a client who is taking aspirin and reports having tinnitus. Which of the following medications should the nurse expect to administer?

A. Tinnitus: Gentamicin is an aminoglycoside antibiotic with ototoxic potential. The presence of tinnitus may indicate early ototoxicity, and withholding the medication is necessary to prevent further auditory damage.

B. Altered taste sensation: Changes in taste are generally mild and not a life-threatening side effect. They do not require withholding the medication but should be documented and monitored.

C. Tremors: Tremors can occur with certain medications or electrolyte imbalances, but they are not a common reason to withhold gentamicin unless accompanied by other signs of neurotoxicity.

D. Photosensitivity: Photosensitivity is not a typical adverse effect of gentamicin. While clients may be advised to avoid excessive sun exposure for some medications, this side effect does not necessitate withholding the drug.

C. Cleanse the skin using a circular motion: Cleaning the site first prevents infection and prepares the area for safe injection. Using a circular motion from the center outward helps remove microorganisms without contaminating the injection site.

E. Hold the needle with the bevel facing up: Positioning the needle bevel up ensures a smoother entry into the dermis and reduces tissue trauma, which is important for accurate intradermal administration.

A. Insert the needle into the dermis layer of skin: The needle is inserted at a very shallow angle into the dermis. Proper placement is essential for the tuberculin test to produce a valid reaction.

B. Inject the medication slowly with the skin pulled taut: Slowly injecting the medication ensures it remains in the dermis and prevents leakage into subcutaneous tissue. Pulling the skin taut stabilizes the area and allows for precise administration.

D. Produce a small wheal on the surface of the skin: The appearance of a small, raised wheal confirms that the medication has been correctly administered intradermally. This wheal is necessary for the subsequent reading of the tuberculin test.
