Question

1. Drug A is an unknow adrenergic antagonist. It is given to a patient for treatment of hypertension. The patient notes side effects including weakness due to a decrease in heart rate, difficulty breathing and ankle edema. Drug A is bonding to a:

a. Muscarinic receptor

b. Cholinergic receptor

c. Adrenergic receptor

d. Nicotinic receptor

2. In regards to Drug A, an unknown adrenergic antagonist given to patients with hypertension, note the specific name of the receptor(s) that Drug A is bonding to.

a. Alpha receptors

b. Alpha and Beta receptors

c. Beta receptors

d. Muscarinic and Nicotinic receptors

3. Drug A, a adrenergic antagonist, is given to patients with hypertension, causes side effect of weakness due to decrease heart rate. Which of the following describes the receptor that drug A is binding to that is causing this side effect?

a. It is binding to alpha receptors on the blood vessels

b. It is binding to beta receptors on the SA node

c. It is binding to Beta receptors on cardiac muscle

d. It is binding to alpha receptors on the SA node

4. Drug A, a adrenergic antagonist, is given to patients with hypertension, causes side effect of difficulty breathing. Which of the following describes the receptor that drug A is binding to that is causing this side effect?

a. It is binding to alpha receptors in smooth muscle of blood vessels

b. It is binding to beta receptors on smooth muscle on bronchioles

c. It is binding to alpha receptors on smooth muscle in bronchioles

d. It is binding to alpha receptors on smooth muscle in alveoli

5. Drug A, a adrenergic antagonist, is given to patients with hypertension, causes side effect of lower extremity swelling and ankle edema. Which of the following describes the receptor that drug A is binding to that is causing this side effect?

a. It is binding to alpha receptors on smooth muscle of myenteric arteries of the GI tract

b. It is binding to nicotinic receptors on skeletal muscle causing skeletal muscle

c. It is binding to alpha receptor on smooth muscle of blood vessels

d. It is binding to beta receptors on smooth muscle of blood vessels

Answer 1

1)It is given in the question that drug A is an adrenergic antagonist.So it will bind to adrenergic receptors. Muscarinic and nicotinic receptors are types of cholinergic receptors.

So answer is C)Adrenergic receptors.

2)The type of receptor present in the heart is beta 1 and the receptor present in bronchioles are beta 2.So the drug A produces the effects by blocking the beta 1 receptors in heart(decrease in heart rate) and beta 2 receptors in bronchioled(bronchoconstriction leading to difficulty in breathing).It also causes vasodilation resulting in ankle edema.(vasodilatory edema)(acting through beta 2 )

So answer is C.

3,4,5 can be answered based on the answer of question 2.

3) Answer is B.It binds to beta receptors in SA node.

4)Answer is B.It binds to the beta receptors in smooth muscles of bronchioles.

5)Answer is D.It binds to beta receptors on smooth muscles of blood vessels.
