Lange Ch 25 Cardiac

The action to be followed if a patient is experiencing a cardiac arrhythmia, specifically a ventricular fibrillation, would be to:

• start an IV
• defibrillate
• order blood to replace blood volume
• administer intravenous lidocaine

Dextran is used parenterally to:

• expand blood plasma volume
• renourish vital tissue
• carry oxygen through the system
• decrease blood viscosity

Which drug can be added to saline for irrigation during a vascular procedure?

• Protamine
• Epinephrine
• Sublimaze
• Heparin

The intraoperative diagnostic test that measures tissue perfusion is:

• blood volume
• respiratory tidal volume
• arterial blood gases
• hematocrit

Passage of a sterile catheter into the heart via the brachial or femoral artery for the purpose of image intensification is called:

• angiography
• arteriography
• cardiac catheterization
• cardioscopy

Hypothermia is employed in cardiac surgery:

• to reduce oxygen consumption
• to reduce elevated temperature
• to slow metabolism
• to induce ventricular fibrillation

Which vessels are harvested for a coronary artery bypass?

• Pulmonary vein and external mammary vein
• Portal vein and hepatic artery
• Saphenous vein and internal mammary artery
• Pulmonary artery and pulmonary vein

The term used to denote the function accomplished by the cardiopulmonary bypass machine is:

• diversion
• dialysis
• perfusion
• profusion

In balloon angioplasty, the dilating balloon is inflated with:

• diluted heparin
• diluted solution of contrast media
• saline
• Ringer's lactate solution

*What position is commonly used for cardiac procedures?

• Supine
• Lateral
• Prone
• Sims
