A nurse is preparing to administer subcutaneous heparin to a client. Which of the following actions should the nurse take?

Insert the needle at least 5 cm (2 in) from the umbilicus.

Massage the site after administering the medication.

Use a 21-gauge needle for the injection.

Aspirate before injecting the medication.

Answer and Explanation

The Correct Answer is A

This is because the umbilicus is a potential site of infection and should be avoided when administering subcutaneous heparin.

Choice B is wrong because massaging the site after administering the medication can cause bruising and hematoma formation.

Choice C is wrong because a 21-gauge needle is too large for subcutaneous injection and can cause tissue trauma and bleeding.

A smaller needle, such as 25- or 27-gauge, should be used.

Choice D is wrong because aspirating before injecting the medication can increase the risk of hematoma formation and is not recommended for subcutaneous heparin.

Correct Answer is D

Explanation

This is because TB is caused by a bacterium that can develop resistance to single-drug therapy, so a combination of drugs is used to prevent or treat drug-resistant strains. Some of the common drugs used for TB are isoniazid, rifampin, ethambutol, and pyrazinamide.

Choice A is wrong because the duration of treatment for active TB is usually 6 to 9 months, not 3 years.

Choice B is wrong because tuberculin skin tests are not reliable indicators of disease activity or response to treatment, as they can remain positive for years after successful therapy.

Choice C is wrong because blood tests to monitor kidney function are not routinely required for TB treatment unless the client has a preexisting renal impairment or is taking drugs that are nephrotoxic.

A. Beclomethasone. B. Estrogen-progestin combination. C. Diphenhydramine. D. Nicotine transdermal system.

Correct Answer is B

Explanation

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.
