25
Describe the changes to a patients breathing pattern if paradoxical respiration was noted
Increased intercostal muscle action Abdominal muscles appear to move inwards
26
Why does the abdomen appear to be 'sucked inwards' during paradoxical breathing?
The increased intercostal muscle action during inspiration draws the diaphragm cranially
27
Name potential causes for paradoxical breathing
Upper airway obstruction diaphragmatic injury (rupture or paralysis secondary to the cervical spinal cord or phrenic nerve injurt) Severe decrease in pulmonary compliance
28
Describe the correct method of auscultating the lungs
Each hemi-thorax is divided into dorsal, middle and ventral lung fields Depending on patient size, this may be split into two or three cranial to caudal zones Each lung field should be auscultated and compared to the adjacent and contralateral fields
29
Describe stridor
High pitched sounds of upper airway origin Occurs when damage or obstruction to the upper airways Abnormally loud sound created as air passes through narrowed airway
30
What should you always check if a high pitched noise is heard on lung auscultation?
Ensure is not referred stridor Complete laryngeal and tracheal auscultation to localise the noise
31
Describe stertor
Lower pitched sound generally of pharyngeal origin Often described as gasp or snore-like Heard on inspiration
32
What would a decrease or absence of lung sounds indicate?
Pleural space disease Can also be soft tissue or organ displacement due to diaphragmatic hernia
33
Describe the changes to a patients breathing pattern that would be noted with pleural space disease
Rapid, shallow breaths Air hunger (dependant on severity)
34
Name potential causes for pleural fluid
Pure transudate (right sided heart failure) Haemorrhage (rodenticide intoxication, neoplasia, trauma) Chylothorax Pyothorax (pus, open wound, extension of lung infection)
35
Over how long is a patient with pulmonary contusions likely to deteriorate?
6-24 hours
36
Laboured inspiration and audible noisy breathing indicates what?
Upper airway issue
37
Laboured expiration indicates what?
Lower airway issue
38
Laboured inspiration and expiration indicates what?
Parenchymal disease
39
Rapid and shallow inspiration and expiration alongside abnormal lung sounds indicates what?
Pleural space disease
40
Paradoxical breathing indicates what?
Loss of negative pressure in the pleural space
41
What methods can provide better information on a patients oxygenation and ventilation rather than mucous membrane colour? and specifically what information do they provide?
Arterial blood gas analysis (PaO2 and PaCO2) Pulse oximetry (SpO2)
42
Why might pulse oximetry be difficult in a dyspnoeic patient?
Potential stressor Requires pulsatile tissue bed to be accurate, perfusion may be altered due to peripheral vasoconstriction
43
Describe a 'depressed' mentation
Alert but not appropriately responsive to stimuli
44
Describe an 'obtunded' mentation
Decreased consciousness or appearing unconscious but rousable with non-nnoxious stimuli
45
Describe a 'stuporous' mentation
Unconscious and only rousble with noxious stimuli
46
Describe a 'comatose' mentation
Unconscious and not rousble with any stimuli including noxious
47
What would episodes of delirium indicate?
Common with space-occupying lesion, problem with brain structure or intermittent increases in ICP
48
Why is it important to carefully assess decreased mentation during a neurological assessment?
May be secondary to hypoperfusion and hypoxia
49
Why should a neurological patient with decreased mentation be monitored after administering fluids (if indicated?)
To re-assess mentation If improved then indicates clinical sign of decreased mentation is attributable to hypoperfusion
50
If a decreased mentation is deemed to not be due to hypoperfusion, what are the next steps?
Full neurological examination Electrolytes and acid-base balance
51
What is involved in a neurological exam?
Gait, ataxia, knuckling, hypermetria, stance, asymmetry, trembling, head tilt Eyes: Pupil size, PLR, eyelid aperture, nystagmus
52
Describe schiff-sherrington posture and what this indicates
Forelimb extensor rigidity and hind-limb flaccidity secondary to a serious spinal cord lesion between T2 and L4
53
Describe decerebrate rigidity
Opisthotonus (arched back) with hyperextension of all four limbs and loss of consciousness
54
Describe decerebellate rigidity
Hyperextension of the forelimbs with variable flexion and extension of the hind-limbs with appropriate level of consciousness
55
When is a deep pain assessment indicates?
Serious spinal cord injury/disease
56
How do you assess withdrawal reflex?
Punching the webbing or skin between the toes on the hind leg
57
How do you assess for deep pain?
Pinching p3 (periosteum) with forceps, gradually close until significant pain response elicited
58
Which scoring system was developed to determine the severity of a neurological injury?
Modified Glasgow Coma Score (MGCS)
59
What is vital to consider when presented with a patient with a head injury? and why?
Not to cause a rise in intra-cranial pressure Increased ICP decreases cerebral blood flow
60
What should be avoided in a patient with a head injury so not to raise ICP?
Applying pressure to jugular veins/jugular blood sampling Placement of intra-nasal catheters or any irritation to the nose as may cause sneezing Inducing gag reflex or administering drugs that can cause vomiting
61
How should a patient with a head injury be positioned and why?
Head and neck elevated 15-30 degrees, with a flat board, to decrease intracranial pressure
62
Which drugs can be administered to decrease intra-cranial pressure?
Mannitol Hypertonic saline
63
How would you calculate cerebral perfusion?
MAP - ICP
64
How should a patient with a suspected spinal or neck trauma be transported?
Backboard
65
What is a nursing consideration in a patient with a spinal injury?
Abnormal urination/difficulty Urination pattern and bladder size should be closely monitored Some may require catheterisation, especially if recumbent for more than 12 hours
66
Why should additional care be taken if a patient with a spinal injury is unconscious/sedated?
Relaxation of the muscle which would normally support the unstable vertebral column
67
What is a potential complication of urinary catheterisation?
Urinary tract infection
68
What can repeated bladder expressions or intermittent catheterisation cause?
Bruising Bladder wall trauma Cystitis
69
List potential nursing considerations for patients with a spinal injury
Assessment of nerve function daily Suitable bedding Regular movement to prevent pneumonia Padding of bony prominences Grooming Care of urinary catheter Mental stimulation
70
How often should a patients nursing care plan be reviewed and why?
At least every 24 hours To ensure objectives are being met by the care implemented
