Answer to Question 1

D
Feedback:
Beta2-receptors are found in the smooth muscle in blood vessels, in the bronchi, in the periphery, and in uterine muscle. Beta2-receptors also cause dilation in the bronchi. Beta1-receptor stimulation would improve some heart disease and are responsible for increased lipolysis. Because beta2-receptors increase release of glucagon and the breakdown of glycogen, increasing serum glucose levels, stimulation of these receptors would exacerbate diabetes.

Answer to Question 2

A
Feedback:
Iron dextran is a parenteral form of iron. It is given intramuscularly and must be given by the Z-track method. It can be very painful. Certainly, deficient knowledge and risk for injury are appropriate diagnoses for this patient but would not be related to the administration of the drug. Because this medication is not given orally, tooth staining would not be a concern.
