Deck 37: Pharmacotherapy of Angina Pectoris and Myocardial Infarction

Question 1

The nurse recognizes that calcium channel blockers prescribed for treatment of angina exert their effect by:
1)Increasing preload.
2)Decreasing afterload.
3)Having a positive chronotropic effect.
4)Having a positive inotropic effect.

Answer 1

2

Question 2

The client is admitted with a diagnosis of angina.The patient's angiogram shows no sign of coronary artery disease.The nurse recognizes that the patient most likely has:
1)Stable angina.
2)Classic angina.
3)Vasospastic angina.
4)Unstable angina.

Answer 2

3

Question 3

The nurse uses which statement to best describe the link between atherosclerosis and coronary artery disease?
1)"Coronary artery disease results when there are spasms around the atherosclerotic areas."
2)"Coronary artery disease results when atherosclerotic plaques break off and cause ischemia."
3)"Coronary artery disease results when atherosclerotic plaques block the inside of the blood vessels."
4)"Coronary artery disease results when atherosclerotic plaques grow large enough to rupture the coronary blood vessels."

Answer 3

3

Question 4

The nurse cautions the client receiving isosorbide dinitrate for treatment of angina that long-term use can lead to the development of:
1)Tolerance.
2)Tachycardia.
3)Hypotension.
4)Urinary retention.

Question 5

A patient asks which conditions will cause his heart to need more oxygen.The nurse answers: (Select all that apply.)
1)"Increased physical activity."
2)"Eating a meal."
3)"Emotional stress."
4)"Watching a television show."

Question 6

The nurse realizes that client teaching regarding the cause of anginal pain was effective when the client states:
1)"The pain is related to remodeling of the heart muscle caused by narrowed arteries."
2)"The pain comes from the heart beating irregularly because of narrowed arteries."
3)"The heart is not pumping enough blood out with each beat because of narrowed arteries."
4)"The pain is from a lack of oxygen getting to the heart, which is caused by narrowed arteries."

Question 7

Nitroglycerine relieves angina in part by vasodilating veins.The nurse understands that this will:
1)Increase coronary artery perfusion.
2)Increase the heart rate.
3)Decrease contractility.
4)Increase cardiac output.

Question 8

The nurse knows that the basic strategies of antianginal therapy are: (Select all that apply.)
1)Increase blood flow to the myocardium.
2)Increase blood flow to the peripheral blood vessels.
3)Increase myocardial contractility.
4)Decrease the oxygen consumption of the brain.
5)Increase blood supply to the heart.

Question 9

A client being medicated with 81 mg of aspirin (ASA)daily following a myocardial infarction (MI)asks the nurse why he is only getting baby ASA.The nurse explains:
1)"This is all the ASA you need right now."
2)"This low dose is effective, and causes less GI bleeding."
3)"High doses of ASA do not prevent recurrences of an MI."
4)"The lower dose is much more economical, because you will need to take this throughout your life."

Question 10

A client diagnosed with myocardial infarction is prescribed thrombolytic therapy.The nurse recognizes the goal of this therapy is to:
1)Dissolve clots.
2)Prevent platelet aggregation.
3)Prevent clot formation.
4)Provide immediate relief of chest pain.

Question 11

The nurse teaches the client that the major difference between stable angina and pain associated with myocardial infarction (MI)is that:
1)Angina is relieved with nitroglycerine and rest.
2)Angina can be fatal.
3)MI pain always radiates to the left arm or jaw.
4)MI pain cannot be treated.

Question 12

Which assessment finding in the client receiving a thrombolytic drug indicates a serious problem that should be reported to the physician immediately?
1)Hypertension
2)Prolonged prothrombin time
3)Excessive bleeding
4)Bradycardia

Question 13

A patient has been diagnosed with coronary artery disease (CAD).Concerning weight and exercise, the patient should be advised:
1)Exercise and weight have no relation to CAD.
2)Weight loss is more important than exercise.
3)Exercise is not necessary.
4)Exercise, even without weight loss, is beneficial.

Question 14

A patient has been diagnosed with coronary artery disease.Concerning alcohol consumption, the nurse counsels that the client should:
1)Completely refrain from alcohol.
2)Limit alcohol to one drink per day.
3)Limit alcohol to two drinks per day.
4)Drink as much as the client prefers.

Question 15

The nurse recognizes that the mechanism of action of beta-adrenergic blockers in the treatment of angina is a(n):
1)Positive chronotropic effect.
2)Negative inotropic effect.
3)Positive inotropic effect.
4)Antidysrhythmic effect.

Question 16

The goal of antianginal therapy is to: (Select all that apply.)
1)Increase blood flow to the myocardium.
2)Increase blood flow to the peripheral blood vessels.
3)Increase myocardial contractility.
4)Decrease the oxygen consumption of the heart.

Question 17

The nurse is caring for a patient with a patient with heart failure, and knows that which finding indicates a likely increase in myocardial oxygen demand?
1)Blood pressure of 154/98
2)Respirations of 26
3)Heart rate of 95
4)Temperature of 98.6

Question 18

The client is admitted with a diagnosis of angina.The chest pain occurred while at rest.The nurse recognizes this type of angina is classified as:
1)Stable angina.
2)Classic angina.
3)Variant angina.
4)Unstable angina.
