A client who is prone to motion sickness is going on a fishing trip on a boat and has been prescribed an antiemetic.
What action should the nurse recommend?
Avoid eating or drinking for 6 hours before the trip.
Take the medication 30 minutes before departing.
Take two doses if relief is not achieved.
Increase fluid intake to prevent urinary retention.
The Correct Answer is B
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.

Correct Answer is D
Explanation
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.
Correct Answer is C
Explanation
This is an antithyroid medication that can be used safely during pregnancy, as it has a lower risk of causing birth defects or fetal hypothyroidism than other drugs. Propylthiouracil inhibits the synthesis of thyroid hormones and also blocks their conversion to the more active form.
Choice A is wrong because radioactive iodine is contraindicated during pregnancy, as it can cross the placenta and damage the fetal thyroid gland.
Radioactive iodine is used to destroy overactive thyroid cells and treat hyperthyroidism.
Choice B is wrong because alendronate is not an antithyroid medication, but a bisphosphonate that is used to treat osteoporosis and prevent bone loss.
Alendronate should not be used during pregnancy, as it may affect fetal bone development and mineralization.
Choice D is wrong because methimazole is another antithyroid medication, but it is not the drug of choice for pregnant women, as it has a higher risk of causing birth defects or fetal hypothyroidism than propylthiouracil.
Methimazole also inhibits the synthesis of thyroid hormones, but does not block their conversion to the more active form.
