NUR 257 Test 2
- SA Node
The primary pacemaker of the heart
Continuously generates electrical impulses for a normal rhythm and rate Coined the natural pacemaker
- AV Node
The secondary pacemaker of the heart.
Provides electrical impedance from the atria when pacemaker is not working = rhythms such as a-fib, etc.
- Ejection Fraction (EF)
percent of end diastolic volume ejected with each heart- beat (left ventricle)
- Cardiac Output
amount of blood pumped by ventricle in liters per minute
- Troponin 1 / 4
Laboratory Test that is an indicator of myocardial injury. Is not an indicator of heart attacks.
- Brain Natriuretic Peptide (BNP)
Laboratory Test that indicates how severe heart failure is.
- C-reactive protein
Laboratory Test that indicates inflammation
- Hardwire
Heart monitor that is applied by the nurse and monitored by the nurse.
- Telemetry
Heart monitor that is applied by the nurse, but monitored by a teleme- try tech.
- Holter Monitor
Also known as ambulatory monitoring. This is a heart monitor placed on a patient that they can go home with. After a few days, the monitor it brought back. 2 / 4
- Exercise Stress test
•Patient walks on treadmill with intensity progressing according to protocols
• ECG, V/S, symptoms monitored • Terminated when target HR is achieved
- Pharmacological Stress Testing
Vasodilating agents given to mimic exercise to stress the heart.
- echocardiogram (ECHO)
•Noninvasive ultrasound test that is used to
• Measure the ejection fraction • Examine the size, shape, and motion of cardiac structures
- Cardiac catheterization
•Invasive procedure used to diagnose structural and functional diseases of the heart and great vessels
- 2-6 hours 3 / 4
Post cardiac catheterization, how many hours should the patient remain on bed rest?
- Kidney
For patients with issues, post-catheterization, nurse should monitor for contrast-induced nephropathy.
- A. Hypovolemia
A client has been admitted to the intensive care unit (ICU) after an ischemic stroke, and a central venous pressure (CVP) monitoring line was placed. The nurse notes a low CVP. Which condition is the most likely reason for a low CVP?
- Hypovolemia
- Myocardial infarction (MI)
- Left-sided heart failure
- Aortic valve regurgitation
- B. A 20-year-old client
While auscultating a client's heart sounds, the nurse hears an extra heart sound immediately after the second heart sound (S2). An audible S3 would be considered an expected finding in which client?
- A 47-year-old client
