When speaking of blood pressure control, we are concerned with beta _ receptors of the heart.
1
When speaking of keeping lung passages dilated, we are concerned with beta _ receptors of the lungs.
2
When a beta 1 receptor is triggered, which of the following is true?
a) if blocked, heart rate and blood pressure decrease
b) if unblocked, heart rate and blood pressure increase
c) if unblocked, heart rate and blood pressure decrease
d) if blocked, heart rate and blood pressure increase
a) if blocked, heart rate and blood pressure decrease
b) if unblocked, heart rate and blood pressure increase
True or False
At high doses, newer beta blockers that have a specificity for beta 1 receptors will have no effect on beta 2.
False
They will have some effect on beta 2.
Who are the two groups of patients that should probably not receive beta blockers?
Asthmatics and diabetics.
