Deck 56: Ophthalmic Drugs

Question 1

When assessing a patient who is receiving a direct-acting cholinergic eyedrop as part of treatment for glaucoma, the nurse anticipates that the drug affects the pupil in which way?

A)It causes mydriasis, or pupil dilation.
B)It causes miosis, or pupil constriction.
C)It changes the color of the pupil.
D)It causes no change in pupil size.

Answer 1

The cholinergic drug acts opposite to the atropine and causes the constriction of the pupil which is known as miosis. The observations option wise are as follows:
The drug mentioned above does not cause pupil dilation rather it causes pupil constriction.
Hence, the option (a) is incorrect.
The drug does not affect the color of the pupil.
Hence, the option (c) is incorrect.
The drug produces a change in the size of the pupil making it small.
Hence, the option (d) is incorrect.
The cholinergic drug causes the constriction of the pupil known as miosis.
Hence, the correct answer is .
