Respiratory Nursing Flashcards

1
Q

Identify the potential causes of hypoxaemia or hypoxia:

A

Insufficient oxygen present
Breathing depression (brain injury, opiods, drugs)
Ventilation insufficiency (pneumothorax)
Diffusion disorder (lung removal, fractured ribs)
Lung circulation disorder
Anaemia
Oedema or arterial thrombus
Muscular-thoracic disorders

Q

What is the difference between hypoxaemia and hypoxia:

Q

What are the signs and symptoms of hypercapnia?

A

Symptoms and signs of early hypercapnia include flushed skin, full pulse, tachypnea, dyspnea, extrasystoles, muscle twitches, hand flaps, reduced neural activity, and possibly a raised blood pressure. According to other sources, symptoms of mild hypercapnia might include headache, confusion and lethargy.

Q

Definition of hypercapnia?

A
Co2 retention (>45mmHg) - normal is 35-45mmHg
To assess paCO2, arterial blood gases test must be performed

Q

Describe how one would assess respiratory status?

A

Past health history
- Medications, Surgery +/- other treatment
 Health assessment
-Subjective
-Objective (physical)
-Nose, Mouth/Pharynx, Neck, Thorax/lungs
 INSPECTION
-Note the shape of the chest, Inspect for deformities and asymmetry, Observe trachea position
PALPATION
 For tenderness, For any abnormalities, Tracheal alignment, Palpate spinous processes, costovertebral angles, Check tactile fremitus, Assess chest wall symmetry and expansion
PERCUSSION
 Top to bottom & side to side (two fingers), Compare (right to left), Note sounds location & quality (chest consolidation will not resonate, just like percussing bone- it’s ‘solid’), Resonance, Abnormal, hyperesonance/dullness)
AUSCULTATION
 For breath sounds top to bottom & side to side (right to left), Compare breath sounds and air entry, Note sound location & quality, Normal V abnormal

Q

Describe the bronchial breath sounds:

very upper bronchi/chest area, loud sounds expected, expiration should be louder than inspiration

Q

Describe the abnormal wheeze breath sounds:

A

 Continuous musical sound

 e.g. bronchitis, emphysema, asthma

17
Q

Describe the abnormal friction rub breath sounds

A

This to do with the pleural space rubbing against the chest wall
Loud, dry, crackling sound
 e.g. pleural inflammation

18
Q

List some of the abnormal respiratory assessment findings:

A

Pursed lip breathing
 Tripod position (sitting up straight, leaning forward with hands on knees)- Unable to lie flat
 Accessory muscle use
 Intercostal retractions (are due to reduced air pressure inside your chest)
 Splinting (holding the pillow)
 Related to pain
 Tachypnoea
 Kussmaul respirations (Regular, rapid & deep respirations) (usually someone is dying)
 Cyanosis
 Clubbing of fingers
 Abdominal paradox

19
Q

What are some of the diagnostics performed to assess for respiratory distress?

A
 Pulse Oximetry
 Sputum Specimen (mucus color, consistency etc)
 Laboratory Tests
 Chest X-Rays
 Capnogram or ETCO2 (end tidal Co2 monitoring)
 Arterial Blood Gases (ABGs)
 Respiratory Function Tests
 Bronchoscopy
 CT Scan
 Ventilation/Perfusion Scan
20
Q

List nursing interventions for respiratory distress:

A
Vital signs
 Ongoing monitoring
 Physical assessment
 Positioning
 Splinting
 Deep breathing & coughing
 Analgesics
Group cares
 Oxygen therapy
 Humidification
 Physiotherapy
 Suctioning
 Hydration
 Administer medications
 Nebulisers/inhalers
 Steroids
 Antibiotics
 Reassurance
 Assistance with ADLs
 Documentation
 Patient education
21
Q

What is tactile fremitus?

A

In common medical usage, it usually refers to assessment of the lungs by either the vibration intensity felt on the chest wall (tactile fremitus) and/or heard by a stethoscope on the chest wall with certain spoken words (vocal fremitus), although there are several other types.
