ST depression indicates
Myocardial Ischemia
A sawtooth pattern with a regular ventricular rhythm is
Atrial Flutter
An ECG that shows no relationship between the P wave and QRS complex is
3rd degree heart block
An AV block where none of the sinus impulses reach the ventricles is
3rd degree heart block
A heart block that closely resembles a normal sinus rhythm is
1st Degree
A patient is receiving mechanical ventilation with +10 PEEP, a PCWP of 26 mmHg indicate
Increased LV pressure
You noticed a dampened waveform on an arterial line, what would you do first?
Check for air bubbles
A chronic hypercapneic patient is admitted to ED, he passed out at home, PA catheter is placed with the following: PAP 26/11, PCWP 5 mmHg, CVP 1 mmHg, BP 72/42, SVR 1240 dynes, CI 1.2L/min/m2
* He is most likely?
Hypovolemic
You see an 82 y.o. women in the ED with h/o CAD, she is conscious and alert. She is c/o chest pain radiating to the left arm, she is diaphoretic, SOB. BP is 120/64, pulse is 54 and irregular, RR is 32, you place her on the monitor and it shows Vfib. Your immediate action is to
Check the Monitor leads
Which of the following might be used in the assessment of a patient c/o chest pain
* Have you taken any nitro?
* Does the pain exist when you take a deep breath?
* What do you think is wrong?
* Were you sleeping, exercising or emotionally upset?
ALL the above
The SA node is located
Right Atrium
What is the normal conduction pattern of the heart?
SA node-AV node-Bundle of His-Bundle Branches-Purkinje fibers
Coronary arteries branch off what blood vessel?
The Aorta
- A Swan-Ganz catheter may be inserted via 3 vessels: Internal/External jugular vein & Subclavian vein A catheter that is placed through the jugular vein and into the superior vena cava until it reaches the right atrium:
Central venous catheter (CVP)
- A Swan-Ganz catheter may be inserted via 3 vessels: Internal/External jugular vein & Subclavian vein A catheter that is placed through the jugular vein and into the superior vena cava until it reaches the right atrium:
Central venous catheter (CVP)
The normal value for anatomic shunt is
< 5%
A blood pressure of 100/70 mmHg is obtained, what is the patient’s mean arterial pressure?
80mmHG
You would recommend immediate defibrillation for what cardiac dysrhythmia
Ventricular Fibrillation
If the sinus node fails as a pacemaker, what USUALLY happens?
The AV node becomes the pacemaker
The RT palpates no pulse on the patient, but the ECG monitor is showing a very irregular, almost non-detectable QRS complex. The RT should
The RT should: Begin chest compressions and call code blue
You are running a 12-lead ECG on a patient and you notice a sudden increase in artifact on the ECG paper. You have noticed that the electrode V2 has fallen off the chest. Where would you reposition this electrode on the patient
4th intercostal space on the left side of sternum
