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.

Correct Answer is B
Explanation

b) Stopping warfarin abruptly without healthcare provider guidance can be dangerous and increase the risk of thrombosis. Signs of bleeding should be reported promptly to the healthcare provider for appropriate management.
c) Being consistent with the intake of leafy greens is important to maintain a stable INR, as these foods contain vitamin K, which can interfere with warfarin.
d) Regular INR monitoring is essential to ensure that the client is within the therapeutic range and to make adjustments to the warfarin dosage if necessary.
