A nurse is providing client education to a client who has had corticosteroids prescribed.
What drug should the nurse teach the client to avoid while taking the corticosteroids?

Dimenhydrinate.

Aspirin.

Ibuprofen.

Famotidine.

Answer and Explanation

The Correct Answer is B

The client should avoid taking aspirin while taking corticosteroids because of the potential drug-drug interaction between them. This interaction may cause a reduction in the blood levels of aspirin and decrease its effectiveness. It may also increase the risk of gastrointestinal side effects such as inflammation, bleeding, ulceration, and perforation.

Choice A is wrong because dimenhydrinate is an antihistamine that is used to prevent and treat nausea, vomiting, and dizziness.

It does not have a significant interaction with corticosteroids.

Choice C is wrong because ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain, inflammation, and fever.

It has a similar interaction with corticosteroids as aspirin, but it is less potent and less likely to cause bleeding.

Choice D is wrong because famotidine is a histamine-2 receptor antagonist that is used to treat and prevent ulcers, gastroesophageal reflux disease (GERD), and other conditions that cause excess stomach acid.

It does not have a significant interaction with corticosteroids.

Correct Answer is D

Explanation

Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. This is because diabetic retinopathy is a condition that occurs when high blood sugar levels damage the tiny blood vessels that nourish the retina, the light-sensitive tissue at the back of the eye. As a result, the retina becomes ischemic (lacking oxygen) and tries to grow new blood vessels that are fragile and leaky.

Choice A is wrong because inability of cells in the eye to reproduce is not a cause of diabetic retinopathy.

The retina has a high metabolic rate and needs a constant supply of oxygen and nutrients to function properly.

Choice B is wrong because increase of aqueous humor in the eye is not a cause of diabetic retinopathy.

Aqueous humor is the clear fluid that fills the front part of the eye, not the retina.

An increase of aqueous humor can cause glaucoma, which is a different eye disorder that affects the optic nerve.

Choice C is wrong because decrease of nerve innervations throughout the eye is not a cause of diabetic retinopathy.

Nerve innervations are the connections between nerves and other tissues, such as muscles or glands.

Diabetic retinopathy affects the blood vessels, not the nerves, of the retina.

A. Levothyroxine. B. Thyroid desiccated. C. Methimazole. D. Liothyronine.

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
