Answer to Question 1

Answer: D

The recommendations for physical activity for adolescents are moderate activity for 30 minutes on 5 or more days per week or vigorous exercise for 20 or more minutes on 3 or more days per week. Only the adolescent who jogs for 30 minutes 5 days per week fits the referenced criteria.

Answer to Question 2

Answer: B
Osteoporosis is a demineralization of the bone in which calcium leaves the bone matrix. One causative factor is lack of weight-bearing activity. Weight bearing helps to move calcium back into the bone, thereby strengthening it. A standard intervention for those attempting to prevent or reverse osteoporosis is beginning an exercise plan that includes weight-bearing activities. Additional calcium in the diet after osteoporosis has begun is not thought to be effective. Strict bed rest may well make the osteoporosis worse because there is no weight-bearing activity. Assisted range of motion exercises are not weight bearing and do not help delay or reverse osteoporosis.
