The nurse receives an order to draw a peak level on a patient prescribed Gentamicin via Intravenous (IV) infusion. When is the best time for the nurse to draw this peak level?
30 minutes before starting the infusion.
30 minutes after infusion is complete
Immediately before the next dose of Gentamicin
1 hour after infusion is complete
The Correct Answer is B
Gentamicin is an antibiotic that is usually administered via IV infusion. The peak level is the highest concentration of the medication in the bloodstream, and it is important to monitor it to ensure therapeutic levels are achieved without reaching toxic levels.
Drawing the peak level 30 minutes after the infusion is complete allows enough time for the medication to distribute throughout the body and reach its peak concentration. This timing provides an accurate representation of the highest drug concentration in the bloodstream. 30 minutes before starting the infusion: Drawing the peak level before starting the infusion would not accurately reflect the peak concentration of the medication in the bloodstream. Immediately before the next dose of Gentamicin: Drawing the peak level immediately before the next dose would not provide an accurate assessment of the highest drug concentration, as the levels would have started to decrease due to elimination.
1 hour after infusion is complete: Waiting for 1 hour after the infusion is complete may result in missing the actual peak concentration of the medication in the bloodstream, as it may have already started to decline.

Correct Answer is A
Explanation
Correct Answer is D
Explanation
The client's complaint of hemoptysis (coughing up blood) and a positive Mantoux test (4 cm induration) suggest the possibility of tuberculosis (TB) infection. TB is an airborne infectious disease, and placing the client in airborne isolation is necessary to prevent the spread of the infection to others.
Antibiotics may be used to treat tuberculosis, but the initial step would be to isolate the client and confirm the diagnosis before starting specific treatment.
A CT scan may be ordered to further evaluate the client's condition, but it is not the immediate action required in this case. Isolation and confirmation of the diagnosis take priority. While the client may require oxygen therapy based on their respiratory symptoms, it is not the primary action to take at this stage. Isolation and further evaluation are necessary before initiating specific treatments.
