Looking for a study guide on the Respiratory management of trauma, obesity, near drowning, and burns? If so then you’ve definitely come to the right place! This information listed for you below correlates well with Egan’s Chapter 30 in Respiratory Therapy school, so you can use it to help ace your exams. 

Near drowning is when someone almost dies from not being able to breathe while being immersed under water. When someone is rescued from a near-drowning situation, it is crucial that first aid and medical attention be implemented immediately.

That, along with obesity, burns, and trauma patients are definitely topics you must know. The good news is, this study guide can help. Are you ready to get started? If so, let’s go ahead and dive right in. 

One more thing before we begin. If your Respiratory Therapy program is like mine, then you probably use the Egan’s Workbook as well. Don’t get me wrong, it’s a solid workbook that can be helpful at times. The problem is, it takes way too long to look up all the answers, so it tends to be more busywork than anything else.

To help with that, we looked up all the answers for you so that you don’t have to waste any more of your valuable time. So if you do need the Egan’s Workbook Answers, you can check out our Workbook Helper. 🙂

Respiratory Management of Trauma, Obesity, Near Drowning, and Burns Practice Questions:

1. How is drowning defined?
The suffocation and death as a result of submersion in liquid.

2. What is near drowning?
A situation in which a victim survives a liquid submersion, at least temporarily.

3. What is dry drowning?
Glottic spasms and prevents water from passing into the lungs.

4. What is wet drowning?
The glottis relaxes and allows water to flood the tracheobronchial tree and alveoli.

Noncardiogenic pulmonary edema.

7. What are the pathologic and structural changes that occur in drowning?

19. When does ARDS usually show up?
It usually shows up 24–48 hours after the incident.

34. What are the surface findings of chest trauma?
Bruising, abrasions, open chest wound, and subcutaneous emphysema.

35. What should you do first when someone has a chest wound?
Ensure that there is a patent airway, provided oxygen, ensure that there is IV access, and remove clothing to assess the injury.

36. What side do you put the patient on?
Put the patient on the injured side.

37. What is a pneumothorax?
Air in the pleural space.

38. What are the signs and symptoms of pneumothorax?
Dyspnea, decreased movement of the involved chest wall, diminished or absent breath sounds on the affected side, and hyperresonance to percussion.

39. What is the treatment for a pneumothorax?

40. What is a hemothorax?
Blood in the pleural space

41. What are the signs and symptoms of a hemothorax?
Dyspnea, diminished or absent breath sounds, dullness to percussion, decreased Hgb, shock depending on blood volume lost.

42. What is the treatment for a hemothorax?
Chest tube insertion with a chest drainage system.

43. What is a tension pneumothorax?
Air in the pleural space that does not escape. This causes the organs to shift and increases intrathoracic pressure.

44. What is flail chest?
Fracture of two or more adjacent ribs in two or more places with loss of chest wall stability.

45. What are the signs and symptoms of flail chest?
Paradoxical movement of the chest wall and respiratory distress.

46. What is cardiac tamponade?
Blood rapidly collects in the pericardial sac, compresses the myocardium and prevents ventricular filling.

47. What are the signs and symptoms of cardiac tamponade?
Muffled heart sounds, decreased output, hypotension, JVD, and increased central venous pressure.

48. What is the treatment of cardiac tamponade?
Medical emergency, pericardiocentesis.

49. What is the most common type of injury from blunt trauma?
Rib fractures.

50. What are the clinical manifestations of rib fractures?

51. What are the clinical manifestations of flail chest?
Tachypnea, tachycardia, asymmetric and uncoordinated movement of the thorax, and paradoxical chest movement.

52. What does a chest tube do?
It drains the pleural space, drains air and fluid from the mediastinal space, and it reestablishes negative air pressure.

53. What is a pleural effusion?
An abnormal collection of fluid in the pleural space.

54. What are the clinical manifestations of a pleural effusion?
Muffled heart sounds, distant, trouble breathing, diminished breath sounds, and a sharp chest pain that worsens with inhalation.

55. What metabolic dysfunction is seen in obese patients?
Insulin resistance, Hyperglycemia, Dyslipidemia (increased triglycerides, decreased HDL), Hypertension, Proinflammatory state (increased cytokinesis), Vascular disruption (increased VEGF), and Increased leptin (feeling of fullness).

56. What is the link between obesity and asthma?
Obese patients are 2x more likely to have asthma than overweight patients.

57. What is obesity hypoventilation syndrome?
Severe obesity linked to hypoventilation during both waking and sleeping hours. It is also known as Pickwickian syndrome. Hypoventilation leads to acidosis and hypoxia.

58. What is the pathogenesis of obesity-associated asthma?
Obesity leads to the secretion of leptin which increases eosinophil chemotaxis (migration out of bone marrow), survival, and adhesion to endothelial cells in the blood vessels. Obesity leads to a decreased total number of eosinophils and redistribution of eosinophils from the bones to the lungs. An increased number of eosinophils in the lungs increases the severity of asthma.

59. The severity of burns is based on what?
The depth (degree) of the burn, percent of body surface area involved, location of the burn on the body, association with other injuries, patient’s age, causative agent, and the respiratory involvement and overall health of the patient.

60. What are the body responses with moderate and major burns?
Sympathetic nervous system manifestations, tachycardia, increased respiratory rate, decreased gastrointestinal motility, and increased blood glucose.

61. What is needed for infection protection with moderate and major burns?
Maintain a protective environment, restrict plants and flowers due to the risk of contact with pseudomonas, restrict the consumption of fresh fruits and vegetables, limit visitors, monitor for manifestations of infection and report them to the provider, administer tetanus toxoid, administer antibiotics to treat infection, monitor peak and trough levels, and use strict asepsis with wound care.

62. What are the airway injuries that occur with burns?
They can result from steam or chemical inhalation, aspiration of scalding liquid, and external explosion while breathing. Their effects might not manifest for 24 to 48 hours. It includes progressive hoarseness, brassy cough, difficulty swallowing, drooling, copious secretions, adventitious breath sounds, and expiratory sounds that include audible wheezes, crowing, and stridor.

63. What should the Respiratory Therapist do for airway injuries with burn victims?
Support the airway and ventilation, and administer supplemental oxygen. Educate the patient and family about airway management, such as deep breathing, coughing, and elevating the head of the bed.

64. What are the types of burns and main burn injuries?
Thermal burn, Chemical burn, Smoke and inhalation injury, Metabolic asphyxiation, and Electrical burns.

65. What is a secondary complication to burns that may occur 12-24 hours later?
Pulmonary edema due to inflammation of the airways

66. What are the 3 classifications of burns?
Superficial (1st degree), Deep (2nd degree), and Full thickness (3rd & 4th degree).

67. What are we concerned about with burns to the face, neck, and chest?
Burns may interfere with breathing and you should be concerned with mechanical obstruction.

68. What are we concerned about with burns to the ears and nose?
The patient is at an increased risk for infection due to low blood supply to those areas.

69. How do you treat compartment syndrome?
Fasciotomy – slit in the skin to allow for the swelling and blood to release.

70. How do you manage a burn on the scene?
Remove the patient from the source of the burning, stop the burning process, assess the patient’s ventilation status, and don’t put ice or cold water on the burns.
