A 48-year-old man presents to the ED complaining of severe substernal chest pain radiating down his left arm. He is admitted to the coronary care unit (CCU) with a diagnosis of myocardial infarction (MI). What nursing assessment activity is a priority on admission to the CCU?
- A. Begin ECG monitoring
- B. Obtain information about family history of heart disease
- C. Auscultate lung fields
- D. Determine if the patient smokes
Correct Answer: A
Rationale: The 12-lead ECG provides information that assists in ruling out or diagnosing an acute MI. It should be obtained within 10 minutes from the time a patient reports pain or arrives in the ED. By monitoring serial ECG changes over time, the location, evolution, and resolution of an MI can be identified and monitored; life-threatening arrhythmias are the leading cause of death in the first hours after an MI. Obtaining information about family history of heart disease and whether the patient smokes are not immediate priorities in the acute phase of MI. Data may be obtained from family members later. Lung fields are auscultated after oxygenation and pain control needs are met.

An OR nurse is preparing to assist with a coronary artery bypass graft (CABG). The OR nurse knows that the vessel most commonly used as source for a CABG is what?
- A. Brachial artery
- B. Brachial vein
- C. Femoral artery
- D. Greater saphenous vein
Correct Answer: D
Rationale: The greater saphenous vein is the most commonly used graft site for CABG. The right and left internal mammary arteries, radial arteries, and gastroepiploic artery are other graft sites used, though not as frequently. The femoral artery, brachial artery, and brachial vein are never harvested.
The nurse providing care for a patient post PTCA knows to monitor the patient closely. For what complications should the nurse monitor the patient? Select all that apply.
- A. Abrupt closure of the coronary artery
- B. Venous insufficiency
- C. Bleeding at the insertion site
- D. Retroperitoneal bleeding
- E. Arterial occlusion
Correct Answer: A,C,D,E
Rationale: Complications after the procedure may include abrupt closure of the coronary artery and vascular complications, such as bleeding at the insertion site, retroperitoneal bleeding, hematoma, and arterial occlusion, as well as acute renal failure. Venous insufficiency is not a postprocedure complication of a PTCA.
The OR nurse is explaining to a patient that cardiac surgery requires the absence of blood from the surgical field. At the same time, it is imperative to maintain perfusion of body organs and tissues. What technique for achieving these simultaneous goals should the nurse describe?
- A. Coronary artery bypass graft (CABG)
- B. Percutaneous transluminal coronary angioplasty (PTCA)
- C. Atherectomy
- D. Cardiopulmonary bypass
Correct Answer: D
Rationale: Cardiopulmonary bypass is often used to circulate and oxygenate blood mechanically while bypassing the heart and lungs. PTCA, atherectomy, and CABG are all surgical procedures, none of which achieves the two goals listed.
The nurse is caring for an adult patient who had symptoms of unstable angina upon admission to the hospital. What nursing diagnosis underlies the discomfort associated with angina?
- A. Ineffective breathing pattern related to decreased cardiac output
- B. Anxiety related to fear of death
- C. Ineffective cardiopulmonary tissue perfusion related to coronary artery disease (CAD)
- D. Impaired skin integrity related to CAD
Correct Answer: C
Rationale: Ineffective cardiopulmonary tissue perfusion directly results in the symptoms of discomfort associated with angina. Anxiety and ineffective breathing may result from angina chest pain, but they are not the causes. Skin integrity is not impaired by the effects of angina.
The public health nurse is participating in a health fair and interviews a patient with a history of hypertension, who is currently smoking one pack of cigarettes per day. She denies any of the most common manifestations of CAD. Based on these data, the nurse would expect the focuses of CAD treatment most likely to be which of the following?
- A. Drug therapy and smoking cessation
- B. Diet and drug therapy
- C. Diet therapy only
- D. Diet therapy and smoking cessation
Correct Answer: D
Rationale: Due to the absence of symptoms, dietary therapy would likely be selected as the first-line treatment for possible CAD. Drug therapy would be determined based on a number of considerations and diagnostics findings, but would not be directly indicated. Smoking cessation is always indicated, regardless of the presence or absence of symptoms.
