factors affecting oxygenation - Answers a. Decreased oxygen-carrying capacity
b. Hypovolemia
c. Decreased inspired oxygen concentration
d. Increased metabolic rate
e. Ineffective gas exchange (lungs)
f. Ineffective pump (heart)
Conditions Affecting chest wall movement - Answers Pregnancy
Obesity
Musculoskeletal abnormalities
Trauma
Neuromuscular diseases
Central nervous system alterations
Influences of chronic lung disease
hypoventilation - Answers Occurs when alveolar ventilation is inadequate to meet the oxygen
demand of the body or eliminate sufficient carbon dioxide
Hyperventilation - Answers A state of ventilation in which the lungs remove carbon dioxide
faster than it is produced by cellular metabolism
Hypoxia - Answers Low oxygen saturation of the body, not enough oxygen in the blood. A state
of ventilation in which the lungs remove carbon dioxide faster than it is produced by cellular
metabolism
,Early signs of hypoxia - Answers Restlessness, elevated BP, tachypnea, tachycardia, pallor, pale
mucous membranes
Late signs of hypoxia - Answers Cyanosis, decreased LOC, behavior changes, confusion, stupor,
bradypnea, bradycardia, low BP, cardiac dysrhythmias
Alterations in Cardiac Functioning - Answers disturbances in conduction, altered cardiac output,
impaired valvular function, myocardial ischemia
Left sided heart failure - Answers 1. Pnea, SOB
2. Crackles
3. Oliguria
4. Frothy Sputum
5. Displaced Apical Pulse (Hypertrophy)
Pulmonary edema
right sided heart failure - Answers 1. Jungular Vein Distention
2. Ascending Dependent Edema
3. Weight Gain
4. Hepatomegaly (Liver Enlargement)
Angina - Answers Pain in the heart region caused by lack of oxygen. Partial obstruction
Myocardial infaction - Answers Heart attack. Complete obstruction
occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart
muscle.The most common symptom is chest pain or discomfort which may travel into the
shoulder, arm, back, neck or jaw

•Substance abuse
•Stress
Nursing care plan ineffective airway clearance - Answers a. Position patient head elevated 30-45
degrees
b. Ambulate in room or hall 2x/day or T&R Q2H
c. Patient to cough or deep breath Q hour
d. Teach patient to take a deep breath, hold for a couple seconds, open mouth, tighten abd
muscle, cough 2-3 times with mouth open
e. Increase fluids to 2500ml for 24 hours, offer fluids patient prefers
Coughing and deep breathing exercises - Answers a. Effective technique for maintaining patent
airway
b. Coughing is deliberate maneuver that is effective when spontaneous coughing is inadequate
(allows patient to remove secretions from upper and lower airways)
c. Deep inhalation (increase lung volume and airway diameter)
d. Deep inhalation (allowing air to pass through partially obstructing mucus plus or objects)
e. Huff cough (stimulates natural cough reflex)
f. Huff cough (used to help move secretions to larger airways)
g. Quad cough/manually assisted cough technique (pt with no abd muscle control-Spinal cord
injuries)
h. Diaphragmatic breathing (encourages deep breathing to increase air to lower lungs)
Chest physiotherapy - Answers a. External chest wall manipulation using percussion, vibration,
or high-frequency chest wall compression
b. Used in conjunction with postural drainage
c. Help mobilize pulmonary secretions in select group of patients
Tracheal or Tracheostomy suctioning - Answers a. Size of catheter should be as small as
possible but large enough to remove secretions
b. Never suction while inserting catheter (avoid trauma to lung mucosa)
