chapter 30 oxygenation

Question 0

Atelectasis

Answer 0

Collapse of alveoli, preventing normal respiratory exchange of oxygen and carbon dioxide

Question 1

After load

Answer 1

Resistance to left ventricular ejection; the work the heart must overcome to fully eject blood from the left ventricle.

Question 2

Atrioventricular (AV) Node

Answer 2

A portion of the cardiac conduction system located on the floor of the right atrium; it receives electrical pulses from the atrium and transmits them to the bundle of His

Question 3

Diaphragmatic breathing

Answer 3

Respiration in which the abdomen moves out while the diagram descends on inspiration

Question 4

Diffusion

Answer 4

Movement of molecules from area of high concentration to a area of low concentration

Question 5

Dyspnea

Answer 5

Sensation of shortness of breathe

Question 6

Dysrhythmia

Answer 6

Deviation from normal pattern of heartbeat

Question 7

Hemoptysis

Answer 7

Coughing up blood from the respiratory track

Question 8

Hemothorax

Answer 8

Accumulation of blood and fluid in the pleural cavity between the parietal and visceral pleural

Question 9

Hyperventilation

Answer 9

Respiratory rate in excess of that required to maintain normal carbon dioxide levels in the body tissues

Question 10

Hypoventilation

Answer 10

Respiratory rate insufficient to prevent carbon dioxide retention

Question 11

Hypoxia

Answer 11

Inadequate cellular oxygenation that may result from deficiency in the delivery or use of oxygen at the cellular level

Question 12

Myocardial contractility

Answer 12

Measure of stretch of the cardiac muscle fiber. It can also affect stroke volume and cardiac output. Poor contraction decrease the amount of blood ejected by the ventricles during each contraction

Question 13

Myocardial infraction

Answer 13

Necrosis of a portion of cardiac muscle caused by obstruction in a coronary artery.

Question 14

Myocardial ischemia

Answer 14

Condition that results when the supply of blood to the myocardium from the coronary arteries is insufficient to meet the oxygen demands of the organ

Question 15

Oxygen therapy

Answer 15

Procedure in which oxygen is administered to a patient to relieve or prevent hypoxia

Question 16

Perfusion

Answer 16

1) passage of fluid through a specific organ or an area of the body. 2) therapeutic measure whereby a drug intended for an isolated part of the body is introduced via the blood stream

Question 17

Pneumothorax

Answer 17

Collection of air or gas in the pleural space

Question 18

Vibration

Answer 18

Fine, shaking pressure applied by hands to the chest wall only during exhalation.

Question 19

Wheezing

Answer 19

Adventitious lung sound caused by a severely narrowed bronchus.
