A

Guarded

24
Q

What is a tension pneumothorax?

A 
Emergency with signs including:
Barrel chest
Cyanosis
Open-mouth breathing
Shock
Shallow and rapid breathing

Perform thoracocentesis immediately

25
Q

What wrap material do cats tend to tolerate better than bandage material?

A

Plastic wrap

26
Q

What is the most common type of hernia secondary to trauma?

A

Diaphragmatic

27
Q

What other situations occur along with diaphragmatic hernias?

A 
Hypovolemic shock
Flail chest
Rib fractures
Pulmonary contusions
Pulmonary edema
Traumatic myocarditis
28
Q

What region of the diaprhagm is most commonly affected

A

Ventrolateral musculature

29
Q

What physical exam findings are noted with diaphragmatic hernias?

A 
Sitting with elbows abducted
Abdomen feels empty
Has trouble lying down
Heart sounds muffled
GI sounds ausculted in chest
30
Q

What radiograph findings are noted with diaphragmatic hernias?

A

Loss of diaphragm detail
Bowel loops in thoracic cavity
Fractured ribs
Pulmonary contusions

31
Q

What organs are most commonly herniated into the diaphragm?

A 
Liver
Small intestine
Stomach
Spleen
Omentum
32
Q

When is a diaphragmatic hernia considered an emergency?

A

Respiratory distress
Hypovolemic shock
Bowel strangulation

33
Q

How should the diaphragm be closed?

A

Simple continuous pattern with 2-0 PDS

Do not freshen the edges

34
Q

What additional diagnostic should be performed with degloving injuries?

A

Radiographs to monitor for deeper lesions

35
Q

What is the preferred lavaging fluid?

A

LRS as this provides least damage to fibroblasts

36
Q

How often should bandages be changed with degloving injuries?

A

Daily until exudate decreases
Then every other day until granulation tissue forms
Then every third day until healing is noted

37
Q

Why should radiographs be performed with bite wounds?

A

External wounds are tip of the iceberg

38
Q

What are good anesthetic drugs for cardiovascular-compromised patients?

A

Oxy/hydromorphone and diazepam IV
Hydro and midazolam IV
Diazepam and ketamine

39
Q

What should be done after placing a Penrose drain?

A

Bandaging it to prevent environmental contamination

40
Q

What is the difference between low and high-velocity firearm wounds?

A

Low-velocity may be stuck in the soft tissue

High-velocity can penetrate bone in a large dog

41
Q

What is the difference between exit and entry wounds?

A

Exit wounds are larger than entry wounds

42
Q

What diagnostics should be performed with gun shot wound?

A

Radiographs of the surrounding area to assess for damage

43
Q

What must be done if a projectile is shot at the eye?

A

The projectile must removed and rads of globe should be taken

44
Q

What legal issues are important with projectile injuries?

A

Take pictures of event
Radiographs
Write down communications
Wrap tape around forceps to prevent damage to bullet, wrap bullet in facial tissues, write pet’s name, ID number, date, site it was taken from, and initials of all who were present during this being removed

45
Q

What is a critical fracture?

A 
An emergency where immediate surgery is needed to keep the life or purpose of the bone in place
Examples include:
Skull fractures
Spine fractures
Open fractures
Displacements
46
Q

What is a semi-critical fracture?

A 
Fractures that may cause discomfort if not addressed soon
E.G
Growth plate fractures
Femoral head/ shoulder/ elbow luxations
Mid/ distral humeral fracture
Pelvic fracture
Os penis fractures
47
Q

What is a non-critical fracture?

A 
Fractures that are not emergent
E.G
Greenstick fractures
Scapular or pelvic fractures
Closed long bone diaphyseal fractures
48
Q

When should a splint not be used?

A

On humerial, femoral, or pelvic fractures

49
Q

When is an amputation indicated?

A 
Severe trauma
Neoplasia
Ischemic necrosis
Severe infection unresponsive to therapy
Paralysis
Congenital defects
Severe arthritis
50
Q

Why should you avoid the base of the tail for amputation?

A

Cutting too close to the tail base can interfere with the perineal nerve, causing incontinence

51
Q

How can a hip luxation be treated in dogs? Cats?

A

Reduce the luxation, apply an Ehmer sling, let sit for 2-12 days. If no correction, will need surgical correction

Cats need surgical correction

52
Q

What is important about elbow luxations?

A

Need to be reduced within 2 days or these become very difficult to correct

53
Q

What directions do the bones of the elbow deviate in elbow luxations?

A

Radius and ulna deviate laterally

Anconeus luxated caudolaterally

54
Q

What should be told to a client over the phone when suspicion of dehiscence is noted?

A

Tell them to place a wrap on the affected area, allow them to carry the patient into the hospital to not place any additional stress to the affected area
