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 D

Explanation

The client will need to have blood levels drawn to monitor the therapeutic and toxic levels of theophylline, a bronchodilator that is used to treat symptoms of asthma and other lung conditions. The normal range of theophylline in the blood is 10 to 20 mcg/mL.

Choice A is wrong because the client should not sprinkle the medication in applesauce or any other food. Theophylline is a sustained-release capsule that should be swallowed whole and not crushed or chewed.

Choice B is wrong because the client should avoid caffeine while on this medication, as it can increase the side effects of theophylline, such as nausea, vomiting, headache, and irregular heart rate.

Choice C is wrong because the client should not limit fluid intake while on this medication unless instructed by the doctor.

Fluid intake helps prevent dehydration and kidney problems that can affect theophylline levels in the blood.

A. Decreased percentage of body fat. B. Multiple health problems. C. Increased rate of absorption. D. Polypharmacy. E. Decreased renal function.

Correct Answer is ["B","D","E"]

Explanation

Older adults are at higher risk of adverse drug reactions due to multiple health problems, polypharmacy, and decreased renal function.

These factors can affect the pharmacokinetics and pharmacodynamics of pain medications and increase the likelihood of drug interactions, overdosage, or toxicity.

Choice A is wrong because the decreased percentage of body fat does not increase the risk of adverse drug reactions in older adults.

In fact, an increased percentage of body fat can alter the distribution and elimination of some drugs.

Choice C is wrong because an increased rate of absorption does not increase the risk of adverse drug reactions in older adults.

In fact, decreased rate of absorption can occur due to reduced gastric motility and blood flow.
