Answer to Question 1

C
Feedback:
There is less risk of systemic absorption and increased local effects if these drugs are combined with epinephrine. Epinephrine causes vasoconstriction, which reduces bleeding, slows absorption, and makes the duration of effect longer. It does sting more when injected, but that is not a reason to use it.

Answer to Question 2

A
Feedback:
Children who are born without a thyroid gland or who have a nonfunctioning gland develop a condition called cretinism. If untreated, these children will have poor growth and development and mental retardation because of the lack of thyroid hormone stimulation. The child would not be at increased risk of renal dysfunction, immune deficiency, or paralytic ileus.
