A nurse is caring for a client who has a new diagnosis of benign prostate hypertrophy and a prescription for doxazosin. The client tells the nurse, “I do not want to take this medication.
I would prefer a natural therapy.” Which of the following supplements should the nurse suggest the client discuss with the provider?

The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:

1. Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.

2. Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.

3. Withdraw the regular insulin from the vial: The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.

4. Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.

This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

Colesevelam is a bile acid sequestrant that lowers cholesterol by binding to bile acids in the intestine and preventing their reabsorption into the bloodstream. Some possible explanations for the other choices are:

Choice A. Chlorpromazine is wrong because it is an antipsychotic medication that has no effect on cholesterol levels.

Choice C. Colchicine is wrong because it is an anti-inflammatory drug that is used to treat gout and other inflammatory conditions, not high cholesterol.

Choice D. Cimetidine is wrong because it is a histamine H2 receptor antagonist that reduces stomach acid production and is used to treat ulcers and gastroesophageal reflux disease (GERD), not high cholesterol.

Normal ranges for cholesterol levels vary depending on the type of cholesterol and the risk factors of the individual, but generally, total cholesterol should be less than 200 mg/dL, LDL cholesterol should be less than 100 mg/dL, HDL cholesterol should be more than 40 mg/dL for men and 50 mg/dL for women, and triglycerides should be less than 150 mg/dL.
