Answer to Question 1

A
Fever and heat may increase a client's pulse rate.
Digoxin is a negative chronotropic drug; it will decrease the client's pulse rate.
A conditioned athlete will have a lower heart rate at rest.
Hypothermia decreases pulse rate.

Answer to Question 2

A
Hypoxia is due to inadequate tissue oxygen at the cellular level. The earliest sign of hypoxia is restlessness; as it progresses, mental status changes, cardiac changes, and cyanosis can occur. Early hypoxia results in an elevated blood pressure. In later hypoxia, vital sign changes such as increased heart and respiratory rate occur. Cyanosis is a late sign of hypoxia.
