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

Levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism. It should be taken on an empty stomach, preferably in the morning, with a full glass of water to facilitate absorption and prevent choking. Taking the medication with food or other substances may interfere with its effectiveness.

Choice A is wrong because levothyroxine does not need to be taken after breakfast.

In fact, taking it after breakfast may reduce its absorption and efficacy.

Choice C is wrong because levothyroxine does not require the patient to remain in the upright position for 30 minutes after administering.

This instruction is more applicable to bisphosphonates, which are drugs used to treat osteoporosis.

Choice D is wrong because levothyroxine should not be taken at night.

Taking it at night may cause insomnia, as well as reduced absorption and efficacy.

Glulisine is a rapid-acting insulin that has an onset of action of 2 to 5 minutes and peaks in 30 to 90 minutes, making it the fastest among the choices. Some possible explanations for the other choices are:

Choice A. Aspart is also a rapid-acting insulin, but it has a slightly longer onset of action (10 to 20 minutes) and peak time (1 to 3 hours) than glulisine.

Choice B. Lispro is another rapid-acting insulin, but it has a similar onset of action (<15 minutes) and peak time (30 to 90 minutes) as glulisine, so it is not the fastest.

Choice C. Regular is a short-acting insulin that has a much longer onset of action (30 to 60 minutes) and peak time (2 to 4 hours) than glulisine, so it is not suitable for fast therapeutic effects.

Normal ranges for blood glucose levels are 70 to 130 mg/dL before meals and less than 180 mg/dL after meals.

Insulin doses are adjusted based on blood glucose monitoring, carbohydrate intake, physical activity, and other factors.
