The nurse notices that an order for intravenous gentamicin for a newly admitted client is half of the normal dose usually ordered for an adult. Before calling the provider for confirmation of the order, the nurse reviews the client's history to check for which preexisting condition that could have prompted the adjustment to the normal dose?
Antibiotic resistance
Renal disease
Liver disease
Interpatient variation
The Correct Answer is B
A) Antibiotic resistance is not a reason to adjust the dose of gentamicin.
B) Gentamicin is primarily excreted by the kidneys. In the presence of renal disease, the dose may need to be adjusted to prevent toxicity.
C) Liver disease does not directly impact the metabolism or excretion of gentamicin, so it is not typically a factor in dose adjustment.
D) Interpatient variation alone may not prompt a specific dose adjustment; individual patient factors, especially renal function, are crucial in determining gentamicin dosage.

C) Stopping calcium supplements may not be necessary, but proper timing is crucial.
D) Taking the medications together can reduce the absorption of both, so they should be spaced apart.
Correct Answer is C

c) Withholding the treatment and promptly notifying the provider about the observed symptoms is the correct immediate response to potential adverse reactions.
