Hemodynamics 2

Which of the following will over-dampen the arterial pressure waveform

• stopcock turned to off position

• Transducer not connected

• Air bubbles in the tubing

• Kinked tubing

• Blood clot in the catheter

Which of the following are indications for central line placement:

• mixed venous blood gas collection

• monitor venous return (fluid status)

• Administration of medications

• Monitoring of left heart pressures

Which of the following values is a reflection of right heart preload:

• CVP

• PVR

• SVR

• PCWP

A patient with ARDS has the PEEP increased to 15 cm from 13. Following the increase, the SaO2% increases from 84-86% on 60% FiO2 and the PVO2 decreases from 42 to 39 mm Hg. What should be done next.

• increase FiO2 to 70%

• Decreased PEEP to 13 cm H20

• Increase PEEP to 17 cm H20

• Maintain PEEP of 15 cm H20

Which of the following will occur as a result of severely decreased stroke volume:

• capillary refill >6 seconds

• decreased cardiac output

• tachycardia

• hypotension

• increased urine output

Which of the following is the best description for the term preload:

• ability of the myocardial muscle to contract

• the resistance of the vessels

• Amount of blood ejected with each beat

• filling volume of the ventricles

Which of the following parameters are included in the formula Cardiac Output:

• SVR

• Heart Rate

• Stroke Volume

• Mean Arterial Pressure

• Pulse Pressure

Upon placement of a pulmonary artery catheter, the pressure is reading 3 cm H20, where is the catheter currently located?

• right atrium

• right ventricle

• pulmonary artery

• pulmonary capillary

Which of the following values are CONTINOUSLY monitored from a pulmonary artery catheter:

• PvO2

• PCWP

• PAP

• CVP

• SVR

Which of the following are used to treat a decreased SVR:

• sodium nitroprusside

• dopamine

• norepinephrine

• nitroglycerin

• epinephrine
