A nurse is caring for a client who has an infection and a prescription for gentamicin Intermittent IV bolus every 8 hr. A peak and trough are required with the next dose. Which of the following actions should the nurse take to obtain an accurate gentamicin serum level?
Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
Draw a trough level immediately prior to administering the medication and a peak level 30 min after the
dose.
Draw a trough level at 0900 and a peak level at 2100.
The Correct Answer is B
To obtain an accurate gentamicin serum level, the nurse should draw a trough level immediately before administering the next dose of medication and a peak level 30 minutes after the dose has been administered. The trough level measures the lowest concentration of the medication in the blood, while the peak level measures the highest concentration.

Correct Answer is B
Explanation
Rifampin can cause body fluids such as urine, sweat, saliva, and tears to turn a reddish-orange color. This is a harmless side effect and is not a cause for concern. The nurse should instruct the client to expect this change in color while taking the medication.
Correct Answer is C
Explanation
The correct answer is choicec. Administer the medication under the client’s tongue.
Choice A rationale:
Administering the crushed medication through the NG tube is inappropriate because sublingual medications are designed to be absorbed through the tissues under the tongue, not the gastrointestinal tract. Crushing and administering it through the NG tube would alter its intended absorption and effectiveness.
Choice B rationale:
Dissolving the medication in water and giving it through the NG tube is also incorrect for the same reasons as Choice A. Sublingual medications are specifically formulated to be absorbed through the mucous membranes under the tongue, and changing the route of administration can affect the drug’s efficacy.
Choice C rationale:
Administering the medication under the client’s tongue is the correct action. Sublingual medications are designed to be absorbed directly into the bloodstream through the tissues under the tongue, bypassing the digestive system and providing rapid onset of action.
Choice D rationale:
While some medications can be safely switched to oral formulations for NG tube administration, such a change is only necessary when the prescribed route (in this case, sublingual) cannot be used. Without contraindications (e.g., inability to hold the medication under the tongue or mucosal issues), the original sublingual route should be followed.
