A patient will be starting therapy with a corticosteroid. The nurse reviews the prescriber's orders and notes that an interaction may occur if the corticosteroid is taken with which of these drug classes?

Choice A reason: You should avoid alcohol intake while taking codeine, not limit it to 12 ounces daily. Alcohol can increase the risk of side effects such as drowsiness, dizziness, and respiratory depression.

Choice B reason: You should not expect to experience diarrhea while taking codeine. Codeine can cause constipation, not diarrhea. You should increase your fluid and fiber intake and use laxatives as prescribed to prevent constipation.

Choice C reason: You should not take the medication on an empty stomach to prevent nausea. Codeine can cause nausea and vomiting, especially on an empty stomach. You should take the medication with food or milk to reduce nausea.

Choice D reason: You should change positions slowly while taking codeine. Codeine can cause orthostatic hypotension, which is a sudden drop in blood pressure when you stand up. This can cause dizziness, fainting, and falls. You should change positions slowly and use caution when walking or climbing stairs.

Choice A reason: This is incorrect because insulin can be given intravenously in certain situations, such as diabetic ketoacidosis, hyperglycemic hyperosmolar state, or perioperative care.

Choice B reason: This is correct because regular insulin is the only type of insulin that can be administered intravenously, as it is a short-acting insulin that has a rapid onset and peak. Other types of insulin, such as intermediate-acting or long-acting, are not suitable for intravenous use, as they have a delayed onset and peak and may cause hypoglycemia.

Choice C reason: This is incorrect because insulin aspart and insulin lispro are rapid-acting insulins that have a faster onset and peak than regular insulin. They are not recommended for intravenous use, as they may cause severe hypoglycemia. They are usually given subcutaneously before meals to control postprandial blood glucose levels.

Choice D reason: This is incorrect because not all forms of insulin can be administered intravenously, as explained above. Only regular insulin can be given intravenously, and the dose may differ from the subcutaneous dose depending on the patient's blood glucose level and insulin sensitivity.
