Answer to Question 1

ANS: D
Bisphosphonates bind to bone crystals to specifically inhibit the activity of osteoclasts, which in turn reduces bone resorption without affecting bone formation. However, since bone formation and resorption come together in the bone turnover process, bone formation does ultimately de-crease.

Answer to Question 2

ANS: A
A resting pulse rate over 100 beats per minute may indicate overdose. The drug should be with-held, and the prescribing health care provider should be notified.
