NURS620 QUIZ 1 HEART
Questions And Answers

Harry comes to your office with waxing and waning ischemic symptoms over a

period of days and weeks, an increase in angina while at rest and transient ST

changes on his electrocardiogram. This presentation leads you to believe that he

is experiencing:




A. a stroke.


B. a myocardial infarction.


C. stable angina.


D. unstable angina.


✓~ Unstable Angina




Answer D


The clinical presentation of unstable angina may


include waxing and waning of ischemic symptoms

,over a period of days or weeks. It often involves


a progressive increase in symptoms in those with


previous stable angina, including rest angina,


and may include transient ST changes on the


electrocardiogram. The differential diagnosis of


unstable angina versus ST-segment elevation


myocardial infarction (STEMI) versus non-


STEMI is confirmed by the elevation of serum


troponin. Important to note is the possibility of


acute coronary syndrome without the alteration in


electrocardiographic display.




A newly discharged outpatient surgery client presents with insidious onset of

edema and dusky blue discoloration of the head and upper extremities. You know

it is a medical emergency and suspect which of the following?




A. Evolving cerebral infarction

,B. Impending myocardial infarction


C. Superior vena cava syndrome


D. Temporal arteritis


✓~ Superior Vena Cava Syndrome




Answer C


Superior vena cava syndrome occurs when there


is obstructed venous return from the upper


extremities, head, and neck region. Symptoms


include edema and dusky blue discoloration of


the upper extremities and head. Both the location


of the obstruction and the rapidity with which it


develops will determine the severity of symptoms.


Diagnostic studies include chest radiography, CT,


and venography. A CT scan is the most widely


used. The most common cause of superior vena


cava syndrome is cancer. Primary or metastatic

, cancer in the upper lobe of the right lung can


compress the superior vena cava. Lymphoma or


other tumors located in the mediastinum can


also cause compression of the superior vena cava.


Less often, the superior vena cava can become


blocked with a blood clot from within. As more


invasive medical procedures are being performed


on clients, this cause of superior vena cava


syndrome is being seen more frequently. Blood clot


(thrombus) formation that causes superior vena


cava syndrome is a complication of pacemaker


wires, dialysis, and other intravenous catheters


that are threaded into the superior vena cava


(SVC). Signs and symptoms of SVC Syndrome


may include shortness of breath and swelling of the


arms and face. The symptoms occur because blood


cannot return to the heart. Management of SVC
