A patient with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?

Until a smaller angle can be restored.

For long-term control of normal eye pressure.

For long-term control of pain and swelling.

Until the excess pressure is reduced.

Answer and Explanation

The Correct Answer is B

A. Until a smaller angle can be restored: Open-angle glaucoma is characterized by a gradual increase in intraocular pressure due to the obstruction of the outflow of aqueous humor, not by a narrow angle. The treatment aims to control eye pressure rather than restore the angle, which is more relevant to acute angle-closure glaucoma.
B. For long-term control of normal eye pressure: Open-angle glaucoma is a chronic condition that requires ongoing management to maintain normal intraocular pressure and prevent damage to the optic nerve. The prescribed eye drops help in managing intraocular pressure over the long term to prevent vision loss.
C. For long-term control of pain and swelling: Open-angle glaucoma typically does not present with pain and swelling. The goal of treatment is to control intraocular pressure rather than address pain or swelling, which are not primary symptoms of this condition.
D. Until the excess pressure is reduced: While initial treatment aims to reduce intraocular pressure, open-angle glaucoma requires ongoing use of medications to maintain normal pressure levels and prevent progression of the disease. Discontinuing the medication after initial pressure reduction can lead to a return of elevated intraocular pressure.

Correct Answer is C

Explanation

A. Administer the medication: Acarbose is an alpha-glucosidase inhibitor that should be taken with the first bite of a meal to effectively manage postprandial blood glucose levels. Administering it before the meal is inappropriate as it can lead to inadequate glucose control.
B. Notify the healthcare provider: While notifying the healthcare provider might be necessary if there are significant issues, it is not the immediate action needed in this situation. The priority is to manage the timing of the medication relative to the meal.
C. Hold the medication until the meal trays arrive: Acarbose should be taken with food to work effectively in controlling blood glucose levels after meals. If the meal is delayed, the medication should be held until the meal is ready to ensure proper administration.
D. Obtain another finger stick blood glucose level: Rechecking the blood glucose level does not address the issue of the timing of the acarbose administration. The focus should be on ensuring the medication is taken with the meal.

A. Accommodation. B. Pupillary constriction. C. Refraction. D. Eye convergence.

Correct Answer is B

Explanation

A. Accommodation: Mydriatic eye drops cause dilation of the pupils, but they do not directly affect the eye's ability to accommodate or focus on near objects. Therefore, accommodation may still be functional, though it can be affected indirectly due to the dilated pupils.
B. Pupillary constriction: Mydriatic eye drops are designed to dilate the pupils, so they inhibit or prevent pupillary constriction. This is the primary purpose of these drops, so pupillary constriction will not occur during their therapeutic effect.
C. Refraction: Refraction refers to the bending of light as it passes through the eye to focus on the retina. This function is generally maintained even when mydriatic drops are used, though changes in pupil size can affect the amount of light entering the eye.
D. Eye convergence: Convergence involves the inward movement of both eyes toward each other to maintain single binocular vision when focusing on a close object. While mydriatic drops primarily affect pupil dilation, convergence can still occur, though it may be affected by the degree of dilation.
