NSG223 exam #1 Questions with Solutions
1. normal PR interval 0.12 - 0.20 seconds
on ECG
2. normal QRS com- 0.06 - 0.12 seconds
plex on ECG
3. 1 small box on ECG 0.04 seconds
4. ECG nursing consid- - clip hair if needed (no shaving)
erations - change electrodes every 24 hours
- do not place electrodes over pacemakers, incisions, or planned incision sites
- remove ECG prior to MRI or other procedure
- educate patient about ECG box's purpose
5. cardiac stress test - within 48 hours of MI***
contraindications - unstable angina
- uncontrolled dysrhythmias
6. cardiac stress test - patient walks on treadmill to stress the heart
information - if unable to walk, meds are given to stress the heart (Dobutamine)
- test is stopped if target heartrate is reached or patient becomes unstable
(dizziness, chest pain, discomfort)
7. patient education - fast for 3 hours
prior to cardiac - avoid stimulants (caffeine, tobacco)
stress test - meds may be taken but beta blocker may be held
- wear comfortable clothing
- report chest pain to technician
8. cardiac catheteriza- - patient remains awake
tion information - patient is NPO
- catheter inserted into a great vessel
- contrast used for left-sided procedure
, NSG223 exam #1 Questions with Solutions
- monitor renal function
- bedrest 2-8 hours post-procedure
- observe access site for bleeding
- monitor for chest pain post-procedure
9. blood flow through Right Atrium > Tricuspid Valve > Right Ventricle > Pulmonary Valve > Pulmonary
the heart Artery > Lungs > Pulmonary Vein > Left Atrium > Bicuspid (Mitral) Valve > Left
Ventricle > Aortic Valve > Aorta > Body > Superior and Inferior Vena Cava
10. automaticity cells pacemaker cells - initiate impulse in the heart
11. excitability ability to respond to a an electrical impulse/stimulus
12. conductivity ability to conduct/transmit electrical impulse
13. P wave represents atrial depolarization (contraction Lead II)
14. PR segment repre- resting of electrical signal at AV node
sents
15. QRS complex repre- ventricular depolarization (contraction) - ventricular rate
sents
16. ST segment repre- relaxation before next contraction
sents
17. T wave represents ventricular repolarization
18. sinus rhythm - considered to be a normal heart rhythm
- rate 60-100 bpm
- regular rhythm
- consistent P wave
- P wave prior to every QRS complex
