Question 1

Cardiac/Vital sign monitors:

Answer 1

Continually or intermittently monitor heart activity and other vital signs

Question 2

Inpatient Monitors:

Answer 2

Dinamaps
monitor BP, HR, Temp, respiration, etc
portable
affordable and user friendly

Question 3

Long Term Ambulatory Monitors

Answer 3

portable ECG

Question 4

What are long term ambulatory monitors used for?

Answer 4

home/prolonged use

mainly BP and HR

Question 5

Central Venous pressure and Arterial-line

Answer 5

A-line
measure CVP
used to treat critically ill patients with infections, thromboses and mechanical complications

Question 6

A-line:

Answer 6

catheter connected to a transducer that converts physiological pressure into an electrical signal visible on monitor

• continuous BP, MAP via catheter at different locations of the body
• radial artery most common place to measure BP; second is femoral artery

Question 7

Overdamped waveform of A-line:

Answer 7

indicated hypotension

Question 8

Underdamped waveform of Aline

Answer 8

hypertension

Question 9

Contraindications to A-line

Answer 9

Raynaud’s, thromboangitis obliterans or end arteries such as the brachial artery
-infection at site

Question 10

Precautions of Acute Care Monitors:

Answer 10

1. if displaced, lose significant amount of blood
2. bleeding from line=direct pressure and call for assistance
3. pt only seen bedside for treatment
4. no hip flexion past 60-80
5. bedrest for 60-90 mins after removal of femoral a-line
6. no bending or pressure at wrist when radial a-line in place

Question 11

CVP

Answer 11

Venous access is used to administer medications or fluid, allow blood sampling, monitor pressure, and provide access for dialysis

Question 12

Contraindications for CVP:

Answer 12

infection at site
SVC syndrome
normal CVP: 2-5 mmHg

Question 13

CVP elevated by:

Answer 13

overhydration

heart failure or PA stenosis

Question 14

CVP decreases with:

Answer 14

hypovolemic shock from hemorrhage, fluid shift, dehydration

negative pressure breathing

Question 15

CVP precautions:

Answer 15

BP cuff on extremity with central line

Question 16

PT Implications of Acute care monitors:

Answer 16

1. observe and verify pt appearance, position and documented line
2. record all readings before, during and after treatment
3. anticipate how intervention may change vital signs
4. trace lines from pt to source
5. ask assistance
6. ensure no tension in each line
