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

Answer and Explanation

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

A. Relax smooth muscles of the bronchial airway. B. Prevent Infection. C. Suppress the cough. D. Promote Expectoration.

Correct Answer is A

Explanation

Aminophylline is a bronchodilator that belongs to the xanthine derivative class of medications. It works by relaxing the smooth muscles surrounding the bronchial airways, which leads to bronchodilation. By dilating the airways, aminophylline helps to relieve bronchospasm, improve airflow, and facilitate easier breathing.

Prevent Infection: Aminophylline is not an antimicrobial medication, and its primary action is not related to preventing or treating infections.

Suppress the cough: While aminophylline may have some antitussive (cough-suppressing) effects, its primary action is bronchodilation rather than directly suppressing the cough reflex. Promote Expectoration: Aminophylline is not primarily indicated for promoting expectoration (bringing up mucus). It mainly focuses on bronchodilation to improve airflow and relieve bronchospasm.
