"If one tablet does not relieve the angina after 5 minutes, take two pills." b. "You can tell the pills are active when your tongue feels a tingling sensation." c. "Keep your nitroglycerin with you at all times." d. "The prescription should last about 6 months before a refill is necessary." e.

12. The nurse is interviewing a patient reporting chest discomfort that occurs with moderate to prolonged exertion. The patient describes the pain as being "about the same over the past several months and going away with nitroglyc- erin or rest." Based on the patient's description of symptoms, what does the nurse suspect in this patient? (Select all that apply.) a. Chronic stable angina (CSA) b. Unstable angina c. Acute coronary syndrome (ACS) d. Acute myocardial infarction (MI) e. Coronary artery disease (CAD
b, e
The ED nurse is caring for a patient with acute pain associated with MI. What are the purpos- es of collaborative management that address the patient's pain? (Select all that apply.) a. Return the vital signs and cardiac rhythm to baseline, so the patient can resume ac- tivities of daily living. b. Prevent further damage to the cardiac muscle by decreasing myocardial oxygen demand and increasing myocardial oxygen supply. c. Aggressively diagnose and treat life- threatening cardiac dysrhythmias and re- store pulmonary wedge pressure. d. Closely monitor the patient for accompa- nying symptoms such as nausea and vom- iting or indigestion. e. Eliminate discomfort by providing pain relief modalities, decrease myocardial oxygen demand, and increase myocardial oxygen supply.
b, e
32. A patient has heart failure related to MI. What intervention does the nurse plan for this pa- tient's care? a. Administering digoxin (Lanoxin) 1.0 mg as a loading dose and then daily b. Infusing IV fluids to maintain a urinary output of 60 mL/hr c. Titrating vasoactive drugs to maintain a sufficient cardiac output d. Observing for such complications as hy- pertension and flushed, hot skin
c
80. The intensive care nurse is monitoring a pa- tient with a right ventricular MI. The pulmo- nary artery wedge pressure (PAWP) reading is 30 mm Hg. What does the nurse do next? a. Increase the IV fluid rate to 200 mL/hour. b. Auscultate the lungs to assess for left-sided heart failure. c. Perform an ECG using right-sided precor- dial leads. d. Place the patient in semi-Fowler's position.
c
Which statement about silent MI is correct? a. In a silent MI, the patient does not have any pain, so there is less myocardial dam- age. b. Diabetic patients are prone to silent MI that goes undiagnosed without complica- tions. c. Silent MI increases the incidence of new coronary events. d. In silent MI, the myocardium is oxygen- ated by increased collateral circulation.

13. A patient with a history of angina is admitted for surgery. The patient reports nausea, pres- sure in the chest radiating to the left arm, ap- pears anxious, skin is cool and clammy, blood pressure is 150/90 mm Hg, pulse is 100, and respiratory rate is 32. What are the priorities of nursing care for this patient? (Select all that ap- ply.) a. Relieve anxiety b. Maintain NPO status c. Improve coronary perfusion d. Improve coronary oxygenation e. Relieve chest pain
c, d, e
Creates channels that will eventually allow oxygenated blood to flow during diastole from the left ventricle to nour- ish the muscle.
cc. Transmyocardial laser revascularization
15. The nurse is talking to a patient with angina about resuming sexual activity. Which state- ment by the patient indicates a correct under- standing about the effects of angina on sexual activity? a. "I won't be able to resume the same level of physical exertion as I did before I had chest pain." b. "I will discuss alternative methods with my partner since I will no longer be able to have sexual intercourse." c. "If I cannot walk a mile, I am not strong enough to resume intercourse." d. "I can resume sexual activity after a rest period."
d
35. The nurse is giving a community presentation about heart disease. Because 95% of sudden cardiac arrest victims die of ventricular fibrilla- tion before reaching the hospital, which teach- ing point does the nurse emphasize? a. Controlling alcohol consumption and quitting cigarette smoking b. Modifying risk factors such as diet and weight, and blood pressure medication compliance c. Recognizing the difference between chron- ic stable angina and unstable angina d. Learning to operate the automatic external defibrillators (AEDs) in the workplace
d
31. Which diagnostic tests are used to assess myo- cardial damage caused by an MI? (Select all that apply.) a. Positive chest x-ray b. Creatine kinase (CK) elevation c. ECG: ST depression d. CK-MB isoenzymes elevation e. Troponin I isoenzyme elevation
d, e
Procedure in which open heart sur- gery is performed without the use of a heart-lung bypass machine.
dd. Off-pump coronary artery bypass (OPCAB)
Ischemia that occurs with angina is limited in duration and does not cause permanent damage of myocardial tis- sue
t
Many patients suffering sudden car- diac arrest die before reaching the hos- pital due to ventricular fibrillation.
