A client has responded poorly to conservative treatment for nausea and vomiting and has subsequently been prescribed dronabinol.
In addition to monitoring the client’s nausea, the nurse should prioritize what assessment after administering the drug?

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

Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.

Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.

Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.

However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.

Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.

However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
