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."
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.

Correct Answer is ["A","C","D"]
Explanation
A. Elevating the head of the bed to 30-45 degrees helps facilitate venous drainage from the brain, thereby reducing ICP.
B. Administering intravenous fluids rapidly is not appropriate, as it can lead to fluid overload and increase ICP.
C. Keeping the client in a calm and quiet environment minimizes stimulation, which can contribute to increased ICP.
D. Administering morphine sulfate as prescribed can provide pain relief, which may help decrease ICP since pain can contribute to increased intracranial pressure.
E. The Valsalva maneuver increases intrathoracic pressure and can lead to increased ICP, making it contraindicated in this scenario.
Correct Answer is B
Explanation
A. Turning the client onto their operative side could increase pressure on the eye and is not an appropriate first action.
B. Administering prescribed pain medication and antiemetic is essential to address the client's severe pain and nausea, which are priority concerns in the postoperative period.
C. While it may be necessary to notify the surgeon if symptoms persist, the immediate priority is to alleviate the client's discomfort.
D. Reassuring the client that these symptoms are normal is misleading; severe pain and nausea postoperatively should be addressed promptly.
