A miotic medication has been prescribed for a client with acute angle-closure glaucoma. The client asks the nurse about the purpose of the medication. Which response should the nurse provide to the client?
"The medication will help block the neural impulses that are sent to the muscles in the eye."
"The medication will help dilate the pupil to allow drainage of fluid to occur."
"The medication causes the pupil to constrict, opening the angle where the iris meets the cornea."
"The medication pulls excess aqueous humor from the eye, into the bloodstream."
The Correct Answer is C
A. This statement is not accurate in the context of miotic medications. Miotic drugs do not work by blocking neural impulses to the muscles. Instead, they directly affect the eye's pupil size and fluid dynamics. This response does not correctly describe the action of miotic agents.
B. This response is incorrect because miotic medications actually constrict the pupil, not dilate it. In acute angle-closure glaucoma, dilation of the pupil would worsen the condition by further blocking the drainage angle. Miotics are used to constrict the pupil, which helps open the angle between the iris and the cornea, thereby facilitating fluid drainage.
C. Miotic medications cause the pupil to constrict (miosis), which helps in opening the narrow angle between the iris and the cornea. In acute angle-closure glaucoma, the angle is closed or narrow, preventing proper drainage of aqueous humor. By constricting the pupil, miotic medications can help to relieve this obstruction and allow better drainage of fluid, thereby reducing intraocular pressure.
D. This statement is incorrect regarding the action of miotic medications. Miotic drugs do not pull aqueous humor into the bloodstream. Their primary effect is on the pupil's size and the angle of the eye to improve drainage. Medications that reduce aqueous humor production or increase its outflow, such as carbonic anhydrase inhibitors or prostaglandin analogs, are responsible for these actions

Correct Answer is A
Explanation
A. Pursed-lip breathing is an effective technique for managing COPD symptoms, particularly tachypnea and dyspnea. It helps to keep the airways open by creating back pressure that prevents the collapse of bronchioles and reduces air-trapping. This technique improves ventilation and helps with the expiration of trapped air, making it a valuable intervention for COPD patients.
B. The Trendelenburg position involves lying flat on the back with the legs elevated higher than the head. This position is not suitable for managing COPD symptoms and can actually worsen breathing difficulties by increasing abdominal pressure on the diaphragm.
C. High-frequency chest wall oscillation (HFCWO) vests are used to help with airway clearance in conditions like cystic fibrosis or chronic bronchitis by loosening mucus. While beneficial for mucus management, they do not specifically address bronchiolar collapse or air-trapping associated with COPD.
D. Measuring the FEV1/FVC ratio is a diagnostic tool used to assess the severity of airflow obstruction in COPD. While this information is important for diagnosis and treatment planning, it is not an immediate intervention to manage symptoms such as tachypnea and dyspnea.

Explanation
Peritonitis
Peritonitis is an infection of the peritoneum (the lining of the abdominal cavity), often related to peritoneal dialysis. It can present with abdominal pain, fever, rigidity, and rebound tenderness,
consistent with the client’s symptoms. Cloudy effluent is also a common sign of peritoneal dialysis- related peritonitis.
Peritoneal dialysis
Peritoneal dialysis is a type of dialysis that uses the peritoneum (abdominal lining) to filter blood. If there is an issue with the dialysis process, it could lead to complications such as peritonitis. This is consistent with the client's symptoms, such as abdominal pain, fever, nausea, vomiting, and cloudy effluent.
