Answer to Question 1

ANS: C
Smoking results in vasoconstriction, a narrowing of blood vessels. BP rises when a person smokes and returns to baseline about 15-20 minutes after stopping smoking. Caffeine increases BP for up to 3 hours. Be sure that patient has not ingested caffeine or smoked 20 to 30 minutes before BP measurement.

Answer to Question 2

ANS: C
An adult's blood pressure tends to rise with advancing age. The optimal blood pressure for a healthy, middle-aged adult is less than 120/80. Values of 120 to 139/80 to 89 mm Hg are considered prehypertension. Blood pressure greater than 140/90 is defined as hypertension. Blood pressure of 98/50 is normal for a child, whereas 115/70 can be normal for an infant.
