Question 1

The client has been ordered to receive a beta-adrenergic blocker. The nurse should anticipate that the client will exhibit:

Accepted Answer

A beta-adrenergic blocker should cause the client to exhibit decreased pulse rate and bronchoconstriction.

Question 2

A nurse is teaching a client how to use phenylephrine (Neo-Synephrine) nasal spray. To avoid systemic absorption, the nurse teaches the client to:

Accepted Answer

The client should insert the spray while sitting up to avoid it being absorbed systemically.

Question 3

Alpha-adrenergic blockers promote vasodilation. The nurse anticipates what expected therapeutic response from the client taking alpha-adrenergic blockers?

Accepted Answer

Vasodilation leads to a decrease in blood pressure.

Question 4

A nurse receives an order to administer epinephrine (Adrenalin) orally to a client. What is the highest priority action on the part of the nurse?

Accepted Answer

Epinephrine is rapidly metabolized in the gastrointestinal tract and the liver and should not be given orally.

Question 5

A client with asthma is receiving metoprolol (Lopressor), a beta blocker for hypertension. The client asks if metoprolol will affect her asthma. What is the best response from the nurse?

Accepted Answer

Metoprolol is formulated to not cause bronchial constriction. Most other beta blockers cause bronchoconstriction and are contraindicated with asthma.

Question 6

The drugs that mimic the effect of norepinephrine are called:

Accepted Answer

Drugs that stimulate the sympathetic nervous system are called adrenergic agonists.

Question 7

Which instruction will the nurse include in a teaching plan for a client taking metoprolol (Lopressor) for treatment of hypertension?

Accepted Answer

Beta blockers slow the pulse rate and decrease the blood pressure, which may cause orthostatic hypotension. The client should rise slowly from a supine or sitting position to prevent orthostatic hypotension. Fluids do not need to be restricted unless client has an underlying condition. Metoprolol does not adversely affect the eyes, so frequent ophthalmic examinations are not required. Metoprolol does not produce a dry cough.

Question 8

A client was stung by a bee. This is the third bee sting the client has received, and the client complains of shortness of breath. What is the adrenergic drug used in emergencies to combat a life-threatening allergic reaction?

Accepted Answer

Epinephrine has powerful beta₂ action that dilates bronchial airways.

Question 9

The client has been started on a treatment regimen that includes albuterol. The nurse should anticipate seeing a decrease in the client's serum _____ level.

Accepted Answer

Albuterol can cause a decrease in the client's potassium level.

Question 10

The client has been placed on a therapeutic regimen that includes Regitine. She tells the nurse that she routinely takes St. John's wort for depression. What should the nurse expect to see as a result of the client taking these medications?

Accepted Answer

The combination of St. John's wort and Regitine will increase the hypotensive effects of Regitine.

Question 11

A client experiencing shortness of breath associated with asthma is given epinephrine (Adrenalin). This medication is considered a nonselective adrenergic drug because it innervates ________ receptor sites.

Accepted Answer

Epinephrine has powerful beta₂ action that dilates bronchial airways and works on all receptor sites.

Question 12

A nurse is infusing dopamine (Intropin) intravenously. The nurse is aware that infiltration of this medication may lead to tissue necrosis. What is an early sign of intravenous infiltration?

Accepted Answer

Swelling could indicate infiltration, along with coolness, tissue pallor, and local pain.

Question 13

Client teaching for patients receiving beta blockers includes instructing the client:

Accepted Answer

When taking beta blockers for a prolonged time, abrupt cessation of the medication may cause rebound hypertension.

Question 14

The client has been started on a treatment regimen that includes atenolol. She complains to the nurse of experiencing weakness. Which is the best response from the nurse?

Accepted Answer

Weakness can be a side effect of atenolol.

Question 15

The actions of the mixed-acting sympathomimetics are _____ the adrenergic receptor sites and _____ the release of norepinephrine.

Accepted Answer

Mixed-acting agents stimulate the release of norepinephrine and directly stimulate alpha and beta receptors.

Question 16

The client comes to a health clinic asking for Sudafed. He tells the nurse that he has a history of diabetes mellitus. What is the most accurate response from the nurse?

Accepted Answer

Sudafed is not recommended for a client who is a diagnosed diabetic.

Question 17

Albuterol sulfate (Proventil) has a short half-life and duration of action. Based on this information, what should the nurse select as an appropriate dosing schedule for this drug?

Accepted Answer

A short half-life indicates that a medication must be given more frequently.

Question 18

A client with asthma is given albuterol sulfate (Proventil), a selective adrenergic drug that stimulates the beta₂-receptor site. Which response should the nurse expect to see in the client?

Accepted Answer

Albuterol sulfate is a bronchodilator.

Question 19

A client is discharged on beta blockers. Which skill is essential for the client's family to learn?

Accepted Answer

Because of the action and side effects of beta blockers, heart rate and blood pressure should be monitored frequently.
