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 C

Explanation

The correct answer is choice C. Keep the tablets at room temperature in their original glass bottle. Rationales: Choice A rationale: Taking one tablet each morning 30 minutes prior to eating is incorrect. Sublingual nitroglycerin is used to relieve acute angina attacks and is taken as needed rather than on a fixed schedule. Choice B rationale: Discarding any tablets not used every 6 months is incorrect. Sublingual nitroglycerin tablets should be replaced every 6 months to ensure potency, but this is not the main teaching point for safe storage. Choice C rationale: Keeping the tablets at room temperature in their original glass bottle is correct. Nitroglycerin tablets are sensitive to light and moisture, and the original glass bottle protects them from these elements, ensuring their effectiveness. Choice D rationale: Placing the tablet between the cheek and gum to dissolve is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue where they dissolve and are absorbed quickly into the bloodstream for rapid relief of angina symptoms

A. Hypomagnesemia. B. Hypocalcemia. C. Hyponatremia. D. Hypokalemia.

Correct Answer is C

Explanation

Lithium can cause hyponatremia by increasing the secretion of antidiuretic hormone and reducing the renal clearance of sodium.

Strenuous exercise can also cause hyponatremia by increasing sweat loss and fluid intake. Therefore, a client who is taking lithium and starting a new exercise program is at risk of developing hyponatremia.

Choice A is wrong because hypomagnesemia is not a common side effect of lithium or exercise.

Choice B is wrong because hypocalcemia is not a common side effect of lithium or exercise.

Choice D is wrong because hypokalemia is not a common side effect of lithium or exercise.

However, lithium can interact with some diuretics that can cause hypokalemia, so the client should avoid taking these drugs without consulting their doctor. Normal ranges for electrolytes are:

Sodium: 135-145 mmol/L

Magnesium: 0.7-1.1 mmol/L

Calcium: 2.1-2.6 mmol/L

Potassium: 3.5-5.0 mmol/L
