(A) Inotropic therapy will increase contractility, which will increase myocardial O2 demand. (B) Decreased

heart rate to the point of bradycardia will increase coronary artery filling time. This should be used

cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. (C) The

goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and

demand. (D) Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or

nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.

QUESTION 2

The nurse would need to monitor the serum glucose levels of a client receiving which of the following

medications, owing to its effects on glycogenolysis and insulin release?

A. Norepinephrine (Levophed)

B. Dobutamine (Dobutrex)

C. Propranolol (Inderal)

D. Epinephrine (Adrenalin)

Correct Answer: D

Section: Questions Set A

Explanation

Explanation/Reference:

Explanation:

(A) Norepinephrine’s side effects are primarily related to safe, effective care environment and include

decreased peripheral perfusion and bradycardia. (B) Dobutamine’s side effects include increased heart

rate and blood pressure, ventricular ectopy, nausea, and headache. (C) Propranolol’s side effects include

elevated blood urea nitrogen, serum transaminase, alkaline phosphatase, and lactic dehydrogenase. (D)

Epinephrine increases serum glucose levels by increasing glycogenolysis and inhibiting insulin release.

Prolonged use can elevate serum lactate levels, leading to metabolic acidosis, increased urinary

catecholamines, false elevation of blood urea nitrogen, and decreased coagulation time.

QUESTION 3

Which of the following medications requires close observation for bronchospasm in the client with chronic

obstructive pulmonary disease or asthma?

A. Verapamil (Isoptin)

B. Amrinone (Inocor)

C. Epinephrine (Adrenalin)

D. Propranolol (Inderal)

Correct Answer: D
