Answer to Question 1

ANS: A
Inotropic agents stimulate the heart to increase the force of contractions, thus boosting cardiac output. Chronotropic agents are given to increase heart rate. Isotonic agents have the same pH as body fluids. Isopropyl agents include rubbing alcohol.

Answer to Question 2

ANS: A
A pulse rate of 100 beats/min in a child who is 3 years old is considered acceptable. Administration of the medication is appropriate. There is no indication for contacting the cardiologist, holding the dose, or requesting further assessment because this is within the expected range.
