The nurse is teaching the client with a new prescription for ibandronate how to take the medication.
Which instruction provided by the nurse is correct?

This is because antiemetics should be given to prevent motion sickness rather than after nausea or vomiting develop. Taking the medication 30 minutes before departing allows enough time for the drug to be absorbed and reach its peak effect.

Choice A is wrong because avoiding eating or drinking for 6 hours before the trip may cause dehydration and low blood sugar, which can worsen nausea and vomiting.

It is better to eat a light meal or snack before the trip and avoid spicy, greasy, or acidic foods.

Choice C is wrong because taking two doses if relief is not achieved may cause overdose and adverse effects.

Antiemetics should be taken as prescribed and not exceeded without consulting a doctor.

Choice D is wrong because increasing fluid intake to prevent urinary retention is not relevant for motion sickness.

Urinary retention is a possible side effect of some antiemetics, such as anticholinergics, but it is not a common problem for most people.

Fluid intake should be moderate and not excessive to avoid stomach distension.

This is because aprepitant can cause dehydration as an adverse effect, so the nurse will want to encourage the client to drink as much liquid as possible.

Choice A is wrong because the client’s temperature would not be affected by aprepitant.

Choice B is wrong because the client must be encouraged for fluid intake as tolerated, so placing an NPO sign on the door would not be appropriate for this client.

Choice D is wrong because elevating the head of the bed would be unnecessary for a client receiving aprepitant.
