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 A
Explanation
Diaphoresis means excessive sweating, which is one of the symptoms of hypoglycemia. Hypoglycemia occurs when the blood sugar level is lower than the normal range, which can cause dizziness, confusion, weakness, hunger, and other signs.
Choice B is wrong because flushing of the face is not a symptom of hypoglycemia.
Flushing can be caused by other conditions, such as fever, allergic reactions, or rosacea.
Choice C is wrong because fruity breath is a symptom of hyperglycemia, not hypoglycemia.
Hyperglycemia means high blood sugar level, which can cause the body to produce ketones that give the breath a fruity odor.
Choice D is wrong because unpredictable behaviors are not a specific symptom of hypoglycemia.
However, hypoglycemia can cause confusion, irritability, or anxiety, which may affect the behavior of some people.
The normal range of blood sugar level for most people is between 70 and 130 mg/dL (3.9 and 7.2 mmol/L) before meals and less than 180 mg/dL (10 mmol/L) after meals.
However, this may vary depending on the individual and the type of diabetes.
It is important to monitor the blood sugar level regularly and treat hypoglycemia promptly by eating or drinking a simple sugar source.
Correct Answer is A
Explanation
Prednisone is a glucocorticoid that suppresses the production of natural cortisol by the adrenal glands. Taking prednisone on alternate days allows the adrenal glands to recover and produce some cortisol on the days without prednisone.
Choice B is wrong because prednisone does not eliminate adverse side effects, but may cause some such as weight gain, fluid retention, increased blood pressure, increased blood glucose, and increased risk of infection.
Choice C is wrong because there is no evidence of steroid tolerance, which means that higher doses are needed to achieve the same effect.
Choice D is wrong because prednisone does not prolong therapeutic effects, but may decrease them over time due to feedback inhibition of cortisol secretion.
Normal ranges for cortisol are 6 to 23 mcg/dL in the morning and 2 to 11 mcg/dL in the afternoon.
