A client with a duodenal ulcer is receiving sucralfate for short-term treatment.
What should the nurse advise the client to avoid?

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.

Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.

Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.

Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.

However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.

Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.

However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
