The nurse is providing client teaching regarding the administration of levothyroxine.
What is the nurse’s priority teaching point?

“Remain in the upright position for 30 minutes after taking it.”.

“Take the medication with a full glass of water.”.

“Take the medication before going to bed at night.”.

“Take the medication after breakfast.”.

Answer and Explanation

The Correct Answer is B

Levothyroxine is a synthetic thyroid hormone that is used to treat hypothyroidism. It should be taken on an empty stomach, preferably in the morning, with a full glass of water to facilitate absorption and prevent choking. Taking the medication with food or other substances may interfere with its effectiveness.

Choice A is wrong because levothyroxine does not need to be taken after breakfast.

In fact, taking it after breakfast may reduce its absorption and efficacy.

Choice C is wrong because levothyroxine does not require the patient to remain in the upright position for 30 minutes after administering.

This instruction is more applicable to bisphosphonates, which are drugs used to treat osteoporosis.

Choice D is wrong because levothyroxine should not be taken at night.

Taking it at night may cause insomnia, as well as reduced absorption and efficacy.

Correct Answer is A

Explanation

Levothyroxine is a synthetic form of thyroxine, the hormone that the thyroid gland normally produces.It is used to treat hypothyroidism by replacing the missing hormone and restoring the normal metabolism.

Some explanations for the other choices are:

• Choice B. Thyroid desiccated is a natural thyroid hormone derived from animal thyroid glands.

It contains both T4 and T3 hormones, which may cause side effects or complications in some people with hypothyroidism.It is not recommended as a first-line treatment for hypothyroidism.

• Choice C. Methimazole is an antithyroid drug that blocks the production of thyroid hormones.

It is used to treat hyperthyroidism, not hypothyroidism.Giving methimazole to someone with hypothyroidism would worsen their condition.

• Choice D. Liothyronine is a synthetic form of T3, the active thyroid hormone.

It is sometimes used in combination with levothyroxine to treat hypothyroidism, but it is not a standard treatment.It has a shorter half-life and more variable effects than levothyroxine, and it may increase the risk of cardiac arrhythmias or osteoporosis.

Normal ranges for thyroid function tests vary depending on the laboratory and the method used, but generally they are:

• TSH: 0.4 to 4.0 mIU/L

• Free T4: 0.8 to 2.0 ng/dL

• Free T3: 2.3 to 4.2 pg/mL

A. “It increases the risk for low blood glucose levels.”. B. “There is no reason ginseng cannot be taken by people with diabetes.”. C. “There is no research to indicate what effect it will have.”. D. “It increases the risk for high blood glucose levels.”.

Correct Answer is A

Explanation

Ginseng is a herbal supplement that may have some antidiabetic effects, such as improving glucose tolerance and insulin resistance. However, ginseng may also interact with certain diabetes medications, especially insulin and sulfonylureas, and cause hypoglycemia (low blood sugar)2. Therefore, the nurse should inform the client about this potential risk and advise them to consult their doctor before taking ginseng.

Choice B is wrong because there is a reason ginseng cannot be taken by people with diabetes without medical supervision.

As explained above, ginseng may lower blood glucose levels too much and cause hypoglycemia.

Choice C is wrong because there is some research to indicate what effect ginseng will have on diabetes.

Several studies have shown that ginseng may have beneficial effects on blood glucose control, but also some adverse effects such as hypoglycemia.

Choice D is wrong because ginseng does not increase the risk for high blood
