A client is being treated for acute closed-angle glaucoma. Immediate treatment to reduce the client's intraocular pressure would include:
1. morphine sulfate to reduce blood pressure.
2. antihistamines for sedation.
3. mannitol administered intravenously.
4. tricyclic antidepressants to relieve anxiety.
Correct Answer: 3
Rationale 1: The client does not have elevated blood pressure.
Rationale 2: Antihistamines would not reduce intraocular pressure.
Rationale 3: Mannitol is an osmotic diuretic that reduces intraocular pressure.
Rationale 4: Tricyclic antidepressants have anticholinergic effects and can lead to dilation of the pupil, further increasing the intraocular pressure.
Global Rationale: Mannitol is an osmotic diuretic that reduces intraocular pressure. The client does not have elevated blood pressure. Antihistamines would not reduce intraocular pressure. Tricyclic antidepressants have anticholinergic effects and can lead to dilation of the pupil, further increasing the intraocular pressure.
