| Question | Answer |
| Why will a penetrating chest would kill a buffalo quicker than it will kill a human being? | a buffalo has a single plural lining so both lungs will collapse |

| What in essence is Frank-Starling's Law of the Heart? | the greater the stretch, the greater the tension it generates when contracted |
| Which portion of the nervous system is mainly responsible for the central control of the blood flow? | sympathetic nervous system |
| The mitral (bicuspid) valve does which of the following? | seprates the left atrium and the left ventricle |
| Which of the following formulas is used to calculate the total amount of blood pumped by the heart per minute or cardiac output? | HR x SV |
| The second heart sound is associated with what mechanical event of the cardiac cycle? | Semilunar valve closure |
| Opening of the semilunar valves occur when which of the following occurs? | the pressures in the ventricles exceed those in the aorta and pulmonary arteries |
| Which of the following equations best protrays the factors determining mean arterial blood pressure? | MAP = CO X SVR |

| Which of the following represents the normal order of structures encountered by blood flowing from the vena cave to the aorta? | RA, tricuspid valve, RV, pulmonary valve, pulmonary artery, pulmonary veins, LA, mitral valve, LV, aortic valve |
| The semilunar (pulmonary and aortic) valves do which of the following? | separate the ventricles from their arterial outflow tracts |
| What are the major effects of peripheral chemoreceptors? | vasoconstriction and increased heart rate |

| What method of chest tube removal has been associated with the lowest level of pneumothorax recurrance? | Remove the chest tube 48 hours after the air leak resolves |
| When using a small-bore catheter with a one-way valve such as a Heimlich valve, how can you determine definitvely that there is or is not a small air leak? | Connect to an underwater seal |
| A patient is suspected of having a pleural effusion. Which x-ray position is the most appropriate to confirm diagnosis? | Lateral Decubitus chest film |
| A chest tube placed anteriorly between the second and third ribs. The tube is probably intended to treat a: | pneumothorax |
