Packet 16 - Alterations in Neural Function Part 1 (4)

Question 1

Which type of medication would be good for a patient experiencing ischemia or HTN?

1. ) alpha₁ agonist 2.) alpha₁ antagonist
2. ) alpha₂ agonist 4.) alpha₂ antagonist
3. ) beta₁ agonist 6.) beta₁ ​antagonist
4. ) beta₂ agonist 8.) beta₂ antagonist

Answer 1

alpha₁ antagonist

Question 2

We have a drug that stimulates alpha₁ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 2

vasoconstriction

stimulates alpha₁ receptors → vasoconstriction

Question 3

We have a drug that stimulates beta₂ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 3

bronchodilation

Stimulates beta₂ receptors → bronchodilation

Question 4

We have a drug that is a nonselective beta blocker. What happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 4

Decreased heart rate & bronchoconstriction

nonselective beta blocker

Decreases work load of the heart.

Helps with tachycardia, HTN, and angina.

Question 5

Adrenergic Receptors (ANS)

In bronchioles, and other sites that have beta-mediated functions (lungs).

a. ) beta₁
b. ) beta₂
c. ) alpha₁
d. ) alpha₂

Answer 5

beta₂

In bronchioles, and other sites that have beta-mediated functions (lungs).

Question 6

We have a drug that blocks alpha₁ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 6

vasodilation

Blocks alpha₁ receptors → vasodilation

Question 7

Adrenergic Receptors (ANS)

In CNS (presynaptic). Can inhibit the release of norepinephrine from sympathetic nerve terminals; thought to be involved in regulation of BP.

a. ) beta₁
b. ) beta₂
c. ) alpha₁
d. ) alpha₂

Answer 7

alpha₂

In CNS (presynaptic).

Can inhibit the release of norepinephrine from sympathetic nerve terminals; thought to be involved in regulation of BP.

Question 8

Which type of medication would be good for a patient experiencing asthma?

1. ) alpha₁ agonist 2.) alpha₁ antagonist
2. ) alpha₂ agonist 4.) alpha₂ antagonist
3. ) beta₁ agonist 6.) beta₁ ​antagonist
4. ) beta₂ agonist 8.) beta₂ antagonist

Answer 8

beta₂ agonist

Question 9

Adrenergic Receptors (ANS)

Vascular smooth muscle (postsynaptic) (vasoconstrict).

a. ) beta₁
b. ) beta₂
c. ) alpha₁
d. ) alpha₂

Answer 9

alpha₁

Vascular smooth muscle (postsynaptic) (vasoconstrict).

Question 10

We have a drug that blocks beta₁ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 10

decreased heart rate

Blocks beta1 receptors → decreased heart rate

Question 11

We have a drug that stimulates beta₁ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 11

increased heart rate

Stimulates beta₁ receptors → increased heart rate

Question 12

Adrenergic Receptors (ANS)

Primarily in the heart.

a. ) beta₁
b. ) beta₂
c. ) alpha₁
d. ) alpha₂

Answer 12

beta₁

Primarily in the heart.

Question 13

We have a drug that blocks beta₂ receptors, what happens?

a. ) vasodilation
b. ) vasoconstriction
c. ) bronchodilation
d. ) bronchoconstriction
e. ) increased heart rate
f. ) decreased heart rate

Answer 13

bronchoconstriction

Blocks beta₂ receptors → bronchoconstriction
