The nurse is providing teaching on the miotic medication the client has been prescribed for glaucoma. The client asks the nurse about the purpose of the medication. Which response should the nurse provide to the client?

"The medication causes the pupil to constrict and will lower the pressure in the eye."

"The medication will help dilate the eye to prevent pressure from occurring."

"The medication will relax the muscles of the eyes and prevent blurred vision."

"The medication will help block the responses that are sent to the muscles in the eye."

Answer and Explanation

The Correct Answer is A

A. Miotic medications work by constricting the pupil, which opens the trabecular meshwork and facilitates the drainage of aqueous humor, thus lowering intraocular pressure in clients with glaucoma.
B. Miotics do not dilate the pupil; they constrict it. Dilation would actually increase intraocular pressure, which is not therapeutic in glaucoma.
C. While these medications do affect eye muscles, they do not specifically prevent blurred vision; their primary effect is on eye pressure.
D. Miotics do not block nerve responses; they work by direct action on the eye muscles to promote fluid drainage and reduce pressure.

C. Bran flakes are high in fiber, which can interfere with the absorption of thyroid medications.

A. Serum Thyroxine B. Serum TSH C. Serum T3 D. Free T4

Correct Answer is B

Explanation

A. Serum thyroxine (T4) is typically decreased in primary hypothyroidism due to reduced thyroid hormone production.
B. In primary hypothyroidism, the thyroid gland fails to produce sufficient hormones, which leads to an increase in thyroid-stimulating hormone (TSH) as the pituitary gland tries to stimulate thyroid function. Elevated TSH is a common finding in primary hypothyroidism.
C. Serum T3 is usually decreased in primary hypothyroidism since the production of T3 and T4 is reduced.
D. Free T4 is typically low in primary hypothyroidism as the thyroid gland is underactive and not producing adequate levels of thyroid hormones.
