NURS-4581 Quiz 3 Questions and 100% Correct Answers 2026/27 Update - UTA
Question 1
0..1 pts
Angina occurs with myocardial ischemia as a result of
Death of myocardial tissue.
Elevated pressure in the ventricles and pulmonary vessels.
Dysrhythmias caused by cellular irritability.
Lactic acid accumulation during anaerobic metabolism.
The myocardium becomes hypoxic and switches to anaerobic metabolism
within 10 seconds. Lactic acid begins to build irritating the cardiac nerve
fibers which sent a pain message to the cardiac nerve and thoracic nerve
roots.
Question 2
0..1 pts
Tachycardia that is a response of the sympathetic nervous system to the
pain of ischemia is detrimental because it is not only increase the oxygen
demand, but it:
Impairs perfusion of the coronary arteries.
May lead to ventricular dysrhythmias.
Causes reflex hypotension.
Increases CO.
The myocardium receives its blood during diastole. In tachycardic rhythms,
there is less time for the myocardium to receive blood resulting in decrease
in perfusion.
Question 3

NURS-4581 Quiz 3
, Amlodipine is ordered for a client with newly diagnosed Prinzmetal's (variant)
angina. When teaching the client, the nurse will include the information that
amlodipine will:
Reduce the "fight or flight response".
Increase the force of myocardial contraction.
Help prevent clotting in the coronary arteries.
Decrease spasm of the coronary arteries.
Prinzmetal's angina is caused by coronary artery spasm. Calcium channel
blockers (e.g., amlodipine, nifedipine [Procardia]) are a first-line therapy for
this type of angina. Platelet inhibitors, such as aspirin, help prevent coronary
artery thrombosis, and beta-blockers decrease sympathetic stimulation of
the heart. Medications or activities that increase myocardial contractility will
increase the incidence of angina by increasing oxygen demand.
Question 4
0..1 pts
A client had a cardiac catheterization and is now in the recovery area. What
nursing interventions should be included in the plan of care? Select all that
apply.
Assessing vital signs every 8 hours.
Assisting the client to the bathroom after the procedure
Assessing the peripheral pulses in the affected extremity.
Checking the insertion site for hematoma formation.
Evaluating temperature and color in the affected extremity.
Observing the catheter access site for bleeding or hematoma formation and
assessing peripheral pulses in the affected extremity for temperature and
and color along with the dorsalis pedis and posterior tibial pulses in the lower
extremity, radial pulse in the upper extremity every 15 minutes for 1 hour,
