Answer to Question 1

A
Bethanechol is contraindicated in patients with active or latent asthma, because activation of muscarinic receptors in the lungs causes bronchoconstriction . It increases the tone and motility of the gastrointestinal (GI) tract and is not contraindicated in patients with reflux. It causes vasodi-lation and would actually lower blood pressure in a hypertensive patient. It causes dysrhythmias in hyperthyroid patients.

Answer to Question 2

B
Women older than 50 years need 1200 mg of calcium per day. Patients should take only enough supplemental calcium to make up for the difference between what the diet provides and the RDA. This patient is getting 1800 mg/day. Excess supplemental calcium can increase risks for vascular calcification, MI, stroke, and kidney stones. She does not need to increase calcium intake. Supplementing with 10,000 units of vitamin D is indicated for documented vitamin D deficiency, which is not evident in this case.
