"The Heart of the Problem" Case Study

Which of Mr. Helms' lab results are abnormal?

• Blood Pressure

• Oxygen Saturation

• Heart Rate

• All of these

What is the function of heart valves?

• To increase blood flow

• To prevent the backflow of blood

• To decrease blood flow

What is the function of papillary muscles?

• Keep the semilunar valves open when ventricles contract

• Allow the AV valves to open when ventricles contract

• Keep the AV valves closed when the ventricles contract

• Close the semilunar valves

What valve will be affected by damage to the papillary muscle in the left ventricle?

• Bicuspid (mitral valve)

• Tricuspid Valve

• Aortic Valve

• Pulmonary Valve

Stroke volume and heart rate are the 2 major factors affecting what?

• cardiac input

• capillary filtration

• cardiac output

• aldosterone system

How will mitral valve prolapse affect stroke volume?

• increases it

• decreases it

• has no effect

how does mitral valve prolapse affect cardiac output and blood pressure?

• Increases them

• Decreases them

• Has no effect

The left side of the heart receives blood from which part of the body?

• systemic circulation

• pulmonary circulation

Does pulmonary blood pressure increase or decrease with left-sided heart failure?

• Increase

• Decrease

• No effect

How does mitral valve prolapse affect capillary filtration in the lungs?

• Increases filtration

• Decreases filtration

• No effect
