assessment finding should the nurse interpret as adverse effect that suggests a more serious
concern? - answer✔rash to the face and trunk
The nurse is caring for a 62-year-old who has orders to receive gentamicin . The client reports
difficulty hearing. What should the nurse do? - answer✔Hold the dose and notify the physician
immediately.
Explanation:Nurses should monitor patients for signs of aminoglycoside-induced ototoxicity.
Since there is a possibility of reversing the condition (or at least arresting it) by discontinuing or
reducing dosage of the drugs, the nurse should immediately contact the physician and hold the
dose until receiving additional guidance.
A client has been admitted to the critical care unit with a diagnosis of peritonitis that has
necessitated treatment with gentamicin. As a result, the care team should be cautious when
concurrently administering other medications that may cause which? - answer✔Because of the
potential for nephrotoxicity and ototoxicity that is associated with gentamicin, other medications
that may lead to these same adverse effects must be used with caution. Gentamicin does not
typically affect immune function,ICP, or hematopoiesis.The correct answer is: Ototoxicity or
nephrotoxicity

also uses oral contraceptives. What is the most important instruction the nurse will give to this

tetracycline."Tetracyclines decrease the effectiveness of oral contraceptives, so the client should
use alternative means of contraception while taking tetracycline.
