This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Ophthalmology
You have been asked to consult in the treatment of an 80-year-old patient. An antimuscarinic drug is being considered. Atropine therapy in the elderly may be hazardous because: 
Select and explain. 
A. Atropine can elevate intraocular pressure in patients with glaucoma, B. Atropine frequently causes ventricular tachycardia, C. Urinary retention may be precipitated by atropine in women, D. The elderly are paicularly prone to develop dangerous hypehermia when given Atropine
A: Atropine can elevate intraocular pressure in patients with glaucoma
Answer: A: Atropine can elevate intraocular pressure in patients with glaucoma 
Explanation: The elderly have a much higher incidence of glaucoma than younger people (and may be unaware of the disease until late in its course). Antimuscarinic agents may increase intraocular pressure in individuals with glaucoma. Elderly men (not women) have a much higher probability of developing urinary retention because they have high incidence of prostatic hyperplasia. Cardiac and hypehermic reactions to atropine are not common in the elderly. Ref: Chong N. (2011). Chapter 23. Lasers in Ophthalmology. In P. Riordan-Eva, E.T.
