N313 Exam 2 questions with correct answers
4 major functions of the respiratory system Correct Answer-1. supplying
oxygen to the body for production
2. removing carbon dioxide as a waste product of energy reactions
3. maintaining homeostasis (acid-base balance) of arterial blood
4. maintaining heat exchange
Chronic obstructive pulmonary disease (COPD) Correct Answer-
includes chronic bronchitis and emphysema, characterized by chronic
airflow limitation. Characterized by hypersecretion of of mucus
obstructs the trachea and bronchi (symptoms: productive cough, and
dyspnea on exertion), and alveolar walls are destroyed leading to
permanent abnormal enlargement (these patients are typically
underweight with a barrel chest and become short of breath with
minimal exertion)
exam findings in patients with COPD Correct Answer-1. Wheezing: due
to narrowed bronchi
2. Barrel chest: occurs from hyperinflation of lungs, due to air trapped in
alveoli from emphysema
3. decreased breath sounds
4. Accessory muscle use: accessory muscles used to force expiration
5. Clubbing: due to growth of vascular connective tissue
6. paradoxical pulse
, chest shape and configuration assessment Correct Answer-1. inspect the
chest: Thoracic cage, Spine, Neck Muscles, Position & Posture, Skin
color & Condition
2. inspect the anterior chest: Note shape and configuration of chest wall,
Assess quality of respirations
normal breathing sounds Correct Answer-1. vesicular: base of the lung;
inspiration lasts longer than expiration
2. broncho-vesicular: 1st and 2nd ICS; equal inspiratory and expiratory
phases
3. bronchial: over the trachea; expiration lasts longer than inspiration
abnormal breathing sounds Correct Answer-1. crackles: caused by fluid
and mucus; sounds like rolling hair together
2. gurgles (rhonchi): caused by narrowing, sounds like a snoring quality
3. friction rub: caused by rubbing; grating sound
4. wheeze: constricted bronchus; squeaky musical sound
edema assessment Correct Answer-firmly depress skin over tibia or
medial malleolus for 5 seconds and release. If there is no indentation,
