A nurse is reviewing the list of current medications for a client who is to start a new prescription for carbamazepine.
The nurse should identify which of the following medications interacts with carbamazepine?

Beclomethasone.

Estrogen-progestin combination.

Diphenhydramine.

Nicotine transdermal system.

Answer and Explanation

The Correct Answer is B

Carbamazepine is an anticonvulsant medication that is used to treat seizures and nerve pain. It works by reducing the activity of certain nerve cells in the brain.

Choice A is wrong because beclomethasone is a corticosteroid that is used to treat asthma and allergic rhinitis. It does not interact with carbamazepine.

Choice B is correct because the estrogen-progestin combination is a hormonal contraceptive that is used to prevent pregnancy and regulate menstrual cycles. It interacts with carbamazepine because carbamazepine can increase the breakdown of estrogen and progestin in the body, making them less effective. The nurse should instruct the client to use an alternative or additional method of birth control while taking carbamazepine.

Choice C is wrong because diphenhydramine is an antihistamine that is used to treat allergies, motion sickness, and insomnia. It does not interact with carbamazepine.

Choice D is wrong because the nicotine transdermal system is a nicotine replacement therapy that is used to help people quit smoking. It does not interact with carbamazepine.

Correct Answer is B

Explanation

Choice A rationale:

The air bubble should not be expelled from the syringe before administering enoxaparin. The air bubble is included to ensure that the entire dose is administered and to help prevent leakage of the medication into the subcutaneous tissue, which can reduce bruising.

Choice B rationale:

After administering enoxaparin, applying firm pressure (but not massaging) to the injection site helps minimize bruising and bleeding. It's important not to massage the site as this can increase the risk of bleeding.

Choice C rationale:

The needle should be inserted fully into the subcutaneous tissue at a 90-degree angle (or at a 45-degree angle if the client has little subcutaneous tissue). Inserting the needle halfway may result in improper administration.

Choice D rationale:

Enoxaparin is a low-molecular-weight heparin that should be administered subcutaneously, not intramuscularly. Administering it intramuscularly could increase the risk of bleeding and is not the appropriate route for this medication.

A. Inject air into the NPH vial. B. Withdraw the NPH insulin from the vial. C. Withdraw the regular insulin from the vial. D. Inject air into the regular insulin vial.

Correct Answer is A

Explanation

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:

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.
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.
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.
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.
