A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?

Choice A rationale:

Levalbuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. Therefore, a decrease in wheezing is a therapeutic effect of the medication, making this the correct choice.

Choice B rationale:

While levalbuterol can cause an increase in respiratory rate as a side effect, it is not considered a therapeutic effect of the medication. The primary goal of levalbuterol is to improve breathing by relaxing the muscles of the airways, not to increase respiratory rate.

Choice C rationale:

Levalbuterol does not directly affect nausea. It is primarily used to treat conditions related to breathing such as asthma and chronic obstructive pulmonary disease.

Choice D rationale:

An increased heart rate is a potential side effect of levalbuterol, not a therapeutic effect.

Choice A rationale:

While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.

Choice B rationale:

Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.

Choice C rationale:

Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.

Choice D rationale:

Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.
