A

Deficiency of blood in a particular area

31
Q

Nasal cannula

A

Disposable, plastic device that delivers oxygen via two protruding prongs for insertion into the nostrils

32
Q

Oxygenation

A

The process of providing cells life-sustaining oxygen

33

Respiration

A

Gas exchange between the atmospheric air in the Alveoli and blood in the capillaries

37
Q

Sinoarterial node SA

A

A mass of tissue in the upper right atrium, just below the opening of the superior vena cava, that initiates the transmission of electrical impulses, causing contraction of the heart at regular intervals; also known as pacemaker

39
Q

Sputum

A

Respiratory secretion expelled by coughing or clearing the throat

40
Q

A

Lower chambers of the heart

44
Q

vesicular

A

Normal sound of respirations heard on auscultation over peripheral lung areas

45

A

Procedure of aspirating pleural fluid

47

A

Maximum amount of air that can be forcefully exhale after a full inspiration

56
Q

Antitussives

A

For non-productive cough
Codeine is an example, codeine turns to morphine in the liver
Not drug of choice for patient with head injury or CNS depression
Contra indicated for a pregnant or lactating women, children under four
Can cause dry mouth


57
Q

Decongestant

A

Oral and nasal can cause rebound congestion
Do not use oral longer than one week, nasal no more than five days

A

Adverse affects drowsiness, dry mouth, epistaxes i.e. nosebleed and paradoxical excitement
Warn patients not to drive until they know how the medication affects them

59
Q

Expectorant action

A

Causes thinning of secretions leading to a more productive cough and dust decreased frequency of coughing. For symptomatic relief of respiratory conditions characterized by dry, nonproductive cough and in the presence of mucus in the respiratory tract

60
Q

Mucolytics action

A

Increases or liquefies respiratory secretions to aid the clearing of the airways and high risk respiratory patients who are coughing up thick tenacious secretions also used to protect liver cells from being damaged during episodes of acestaminophen
