Final prep Flashcards
What is the 1st sign often seen on an ECG in the case of acute MI?
ST segment elevation which normally appears within first few hours of injury
After hours to days what is the next sign often see on an ECG after acute MI within hours to days?
T wave inversion
T or F: ST segment can return to normal baseline within days to weeks following an acute MI

T or F: The t wave never fully becomes upright following acute MI
False: The T wave becomes upright after period of week or months
Positive inotropics: A. Increase rate of contraction B. Increase contractility of heart muscle C. Decrease force of contraction D. Decrease rate of contraction

B. Constrict
A. Dilate
Morphine will cause pupuls to
A. Dilate
B. Constrict

A fully compensatory pause is seen after which type of heartbeat? A. NSR B. PVC C. Paroxysmal atrial tachycardia D. VT
B. PVC
T or F: The air/O2 intake valve should not open when resuscitation bag is squeezed;
True: this will allow the gas to escape rather than be directed to the patient
A 10 year old child has been intubated, what compression:ventilation ratio should be used with two rescuers?
A. 3:1
B. 5:1
C. 30:2 per minute
D. 100 compressions: 8-10 ventilations per minute
D. 100 compressions: 8-10 ventilations per minute if child is intubated
A mouth to valve resuscitation device is being used on an apneic patient; the RT delivers a breath but no chest rise is seen; what should be done next? A. Begin chest compression B. Request a lateral neck x-ray C. Check the valve for proper position D. Perform abdominal thrusts
C. Check the valve for proper position
What site should an ABG be drawn from during CPR? A. Carotid B. Radial C. Brachial D. Femoral
D. Femoral
When one rescuer is performing CPR on an unintubated adult, what chest compression:ventilation ratio should be used A: 5:1 B. 5:2 C. 15:2 D. 30:2
D. 30:2
To ensure that a manual ventilator is ready for use you would
1. make sure that no gas escapes through the outlet port when it is closed off and the bag is squeezed
2. squeeze the bag, and make sure that the air/O2 reservoir intake valve closes properly
3. Squeeze the bag, and make sure non-rebreathing valve opens properly
4. Feel for air leaving the outlet port when bag is squeezed
5. Squeeze the bag and make sure that the air O2 reservoir intake valve opens properly.
A. 1, 2, 3, 4
B. 1, 2, 5
C. 4,5
D. 2, 3
A. 1, 2, 3, 4
The air intake valve should not open when ambu bag is squeezed
T or F: Gas normally will escape through the outlet port when the bag is squeezed
F; No gas should escape through the outlet port when bag is squeezed
If a breath cannot be delivered with bag/mask ventilation what should you do?
Check 1 way valve to be sure not put together backward
T or F: If supplemental O2 is not being used to ventilate what should you do to the O2 nipple on the mask or t piece?
It must be capped off if not being used or air will leak out during delivered breaths
If an obstruction occurs to the expiratory one way valve it should be cleared within _____ seconds.
20
T or F: You should feel air leave the outlet port of the non rebreathing valve when the bag is squeezed.
True;
If you occlude the outlet port and then squeeze you won’t feel any leaks & pop off valve would open; if not occluded you should feel air leave when bag is squeezed
