Question 1: 1. bony fractures and possible rib fractures, which may impact ventilation

• palpate for crepitus
• subcutaneous emphysema which may be a sign for a pneumothorax
• soft tissue injury

Answer:

Palpate the chest for Question 2: Results from pump failure in the presence of adequate intravascular volume. There is a lack of cardiac output and end organ perfusion secondary to a decrease in myocardial contractility and/or valvular insufficiency.

Ex: MI's or dysrhythmia are common causes

Answer:

Cariogenic Shock

Question 3: H,I

Answer:

Secondary Survery

Question 4: Prehospital shock index pg. 85

Answer:

Flail chest

Question 5: 1. Preparation

• Preoxygenation
• Pretreatment
• Paralysis and Induction
• Protecting and positioning - v
• Placement of proof - secure the tube
• Post intubation - secure ETT Tube, get X-ray for placement

Answer:

Steps of Rapid Sequence Intubation Question 6: occurs as a result of maldistribution of an adequate circulating blood volume with the loss of vascular tone or increased permeability.

Ex: Anaphylactic - release of antihistamines

Septic Shock - systemic release of bacterial endotoxins, resulting in increased vascular permeability and vasodilation. Neurogenic shock - spinal cord injury results of loss in sympathetic nervous system control of vascular tone.

Goal: Volume replacement and vasoconstriction

Answer:

Distributive Shock

Question 7: Get Resuscitation Adjuncts

L - Labs (maybe a lactic acid), a b g 's, blood type M - monitors N - naso or oro gastric tubes O Oxygen and ETC02 monitors P - pain assessment and management

Answer:

G

Question 8: 1. Suction the airway

2, Use care to avoid stimulating the gag reflex

• If the airway is obstructed by blood or vomitus secretions, use a rigid suction device

If foreign body is noted, remove it carefully with forceps or another appropriate method

Answer:

If Airway is not patent Question 9: from hemorrhage is leading cause. Hypovolemia is caused by decrease in the amount of circulating volume. Goal is to replace volume.

Answer:

Hypovolemic Shock

Question 10: inspect, auscultate, palpate

any spontaneous breathing, rate, depth, and degree of effort, use of accessory muscles lacs, contusions, auscilate lung sounds and heart sounds

Answer:

Head to toe assessment: Chest

Question 11: Stroke Volume X HR

Answer:

Cardiac Output =

Question 12: 1. Apnea

• GCS 8 or less
• Maxillary fractures
• Evidence of inhalation injury (facial burns)
• Laryngeal or tracheal injury or neck hematoma
• High risk of aspiration and patients inability to protect the airway
• Compromised or ineffective ventilation

Answer:

Following conditions might require a definitive airway

Question 13: Hemothorax:

Answer:

• Hypotension

2. JVD

• Muffled heart sounds

Question 14: 1. The tongue obstructing the airway

• loose or missing teeth
• foreign objects
• blood, vomit, or secretions'
• edema
• burns or evidence of inhalation injury

Auscultiate or listen for:

• Obstructive airway sounds such as snoring or gurgling
• Possible occlusive maxillofacial bony deformity
• Subcutaneous emphysema

Answer:

Inspect the mouth for:

Question 15: .. activation: .... are found in the carotid sinus and along the aortic arch, are sensitive to the degree of stretch in the arterial wall. When the receptors sense a decrease in stretch, they stimulate the sympathetic nervous system to release Epi, norepi, causing stimulation of cardiac activity and constriction of blood vessels, which causes a rise in heart rate and diastolic blood pressure

Answer:

Baroreceptors:

Question 16: immobilize cervical spine, tenderness, tracheal deviation

Answer:

Head to toe assessment: Neck and cervical spine
