A client prescribed cyclobenzaprine hydrochloride for muscle spasms has an admission history of which condition that would prompt questioning the prescription?

• A. Asthma
• B. Hypertension
• C. Angle-closure glaucoma
• D. Diabetes

Answer: (C)

The key idea here is how a drug’s anticholinergic effects can impact eye conditions like angle-closure glaucoma. Cyclobenzaprine has anticholinergic properties, which can cause pupil dilation (mydriasis). In angle-closure glaucoma, the drainage angle is already narrowed, so pupil dilation can further restrict outflow of aqueous humor and raise intraocular pressure, potentially triggering an acute glaucoma attack. That makes a history of angle-closure glaucoma a reason to question the prescription or seek an alternative. Asthma, hypertension, and diabetes don’t inherently pose the same glaucoma-related risk with this medication, so they don’t prompt the same level of concern in this context.
