Question 5

What is the normal range for O2 sat

Answer 5

> 95%

Question 6

What is the equation for Max HR

Answer 6

206.9 - (.67 x age)

Question 7

Your pt’s ECG shows quivering where P waves should be with an irregular ventricular rhythm (random QRS complexes). What arrhythmia is it and what should you do as a PT?

Answer 7

Atrial Fibrillation

• If this is a new dx, hold PT until treated, patient is at risk for a mural thrombi/stroke
• If chronic and patient not in CHF, treat to tolerance

Question 8

Your pt’s ECG shows multiple P waves with no change in PR intervals, P waves to QRS complexes vary from 2-4 P waves for every QRS complex. What arrhythmia is it and what should you do as a PT?

Answer 8

Second degree AV block, T2

*Hold PT for medical mangement, watch for progression to 3rd degree heart block

Question 9

Your pt’s ECG shows no relationship between P waves and QRS complex (wide) = no communication between atria and vents. What arrhythmia is it and what should you do as a PT?

Answer 9

3rd degree AV block

*Hold PT for medical mangement

Question 10

Your pt’s ECG shows a wide QRS complex without P wave. What arrhythmia is it and what should you do as a PT?

Answer 10

Premature Ventricular Complex
*PT is fine unless there is a change in frequency or quality of PVC, 6 PVC/min may be problematic (couplet can become triplet = v-tach)

Question 11

What do you do if your patient is in ventricular tachy?

Answer 11

Medical emergency, get help!

*Patient may be stable with CO but can progress rapdily to pulseless= Never treat pts with vent tachy!

Question 12

Your pt’s ECG shows erratic quivering of ventriclar muscle resulting in no CO. What arrhythmia is it and what should you do as a PT?

Answer 12

Ventricular Fibrillation

*Do not do PT!!!!!

Question 13

In general never do PT in what type of ECG changes

Answer 13

1. ) ST changes
2. ) Onest, increase or change in PVC
3. ) Onset of atrial flutter or fib
4. ) Progression of heart block

Question 14

Besides automatic and manual, what are 2 other ways to get BP?

Answer 14

Arterial line and Central Line (measure directly-CVP)

*Also able to do blood draws, usually inserted in femoral (limit hip flexion to less then 90) or radial artery

Question 15

What is the phlebostatic point

Answer 15

Part of arterial line that has the sensor (catheter tip)

Question 16

These are inserted in subclavian or jugular vein, rests in sup vena cava and measure central venous pressure directly, allows meds to be adminstered

Answer 16

Central Lines

*assess fluid in the R vent

Question 17

You patient has poorly compliant lungs, show signs of hypoxia and hypercarbia. What type of ventilation do you think they will be on?

Answer 17

Pressure Ventilation
*Provides more support at lower PIP (peak inspiratory pressure) for poorly compliant lungs vs. volume ventilation. This is the preferred load for non-compliant / stiff lungs.

Volume ventilation good for patient with more compliant lungs, it is more comfortable and has a guaranteed minute ventilation

Question 18

What type of ventilation mode provides the most support?

Answer 18

Assist Control

*Machine delivers every breath weather it is mechanical or spontaneous

Question 19

Your patient is trying to wean themselves of ventilator assistance. What mode of ventilation do they most likely have?

Answer 19

Synchronized intermittent mandatory ventilation (SIMV)

Question 20

Equation for pulmonary compliance

Answer 20

Vol/Pressure

Question 21

If on volume mode and the required pressure decreases what happens to compliance?

Answer 21

Improves/increase

Question 22

If on pressure mode and the required volume increases,what happen to compliance?

Answer 22

Improves/increase

Question 23

You are working with a patient with a ventriculostomy catheter. You notice the ICP pressure is 12 mmHg. You know that this is too high and it is going down very slowly. What should you do?

Answer 23

Limit or stop exertional activity; patients who are bagged or deliberately hyperventilated for increased ICP should have minimal therapy involvement

*Norm range 0-10

Question 24

You patient is receiving hemodiaylsis. Can they still have PT?

Answer 24

YES. This is not contraindicated. Expect patient to show signs of fatigue.

Question 25

What is the max score that would classify your patient as in a coma on the glasgow coma scale

Answer 25

9 or less indicates coma
