Answer to Question 1

ANS: B
Infants and children require a total daily digoxin dose that is approximately twice that of an adult on a basis of the ratio of weight to dose. This increased requirement for digoxin is thought to be the result of a greater binding strength of the child's developing myocardial digoxin receptors.

Answer to Question 2

ANS: C
There are some basic facts health care providers should tell patients about OTC products. In particular, if they do not get well, they should stop treating themselves and talk with a health care professional. Also, the health care professional must be aware of all over-the-counter meds being taken because of the dangers of interaction.
