Question 1 of 11
Which statement describes how unstable angina differs
from chronic stable angina?
• Correct
o Unstable angina has a random onset.
Unstable angina differs from chronic stable angina because it is not
predictable and can have a random onset.
•
o Stable angina is not relieved by resting.
Stable angina can be relieved by resting.
•
o Stable angina requires immediate treatment.
Unstable angina, not stable angina, is a medical emergency and
requires immediate treatment.
•
o Unstable angina does not change in intensity.
Unstable angina differs from chronic stable angina because it is not
predictable.
Question 2 of 11
Unstable angina is considered an emergency because
of which pathophysiological occurrence?
• Correct
o Platelet aggregation blocks the artery.
Unstable angina results from a ruptured plaque that causes platelet
aggregation, which forms a thrombus. The thrombus can partially block
blood flow to the heart resulting in myocardial injury, making this a
medical emergency.
, •
o Fatty streaks form a plaque on the arterial wall.
Plaque formation occurs over time and is associated with angina but
does not explain why unstable angina is an emergency.
•
o Platelet destruction causes myocardial ischemia.
Platelet aggregation, not destruction, can cause myocardial ischemia.
•
o Plaques narrow the arterial wall causing infarction.
A plaque narrows the arterial wall but does not by itself cause
infarction. This does not explain why unstable angina is an emergency.
Question 3 of 11
A patient has been diagnosed with acute coronary
syndrome. Which assessment findings would the nurse
expect to see?
• Correct
o
Pain occurs at rest.
The pain from acute coronary syndrome may occur while the patient is
active or at rest, asleep or awake.
•
o
Pain only occurs after activity.
Chest pain that only occurs after activity is associated with chronic
stable angina.
• Correct
o
Pain may radiate to other areas.
