The nurse is reviewing medication prescriptions.
Which is an appropriate dosage and frequency of cimetidine?
800 mg PO at bedtime.
150 mg PO b.i.d.
20 mg PO b.i.d.
300 mg PO at bedtime.
The Correct Answer is A
800 mg PO at bedtime is an appropriate dosage and frequency of cimetidine for the treatment of gastric ulcer. Cimetidine is a histamine H antagonist that reduces the secretion of gastric acid.
Choice B is wrong because 150 mg PO b.i.d. is too low of a dose for cimetidine. The usual adult dose for duodenal ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.
Choice C is wrong because 20 mg PO b.i.d. is not a valid dose for cimetidine.
The lowest available tablet strength is 100 mg.
Choice D is wrong because 300 mg PO at bedtime is also too low of a dose for cimetidine.
The usual adult dose for gastric ulcer is 800 mg PO once a day at bedtime or 300 mg PO four times a day.

Correct Answer is C
Explanation
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.
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.
