Question 1: resuscitation

Answer:

prime determinants of cellular perfusion

• the heart

• fluid volume

• blood vessels

4.Question 2: ? Decreased LOC, anxiety, disorientation, belligerence, bizarre behavior (brain and CNS) ? Tachycardia, decreased systolic and pulse pressure (heart and cardiovascular system) ?Rapid, shallow breathing (respiratory system) ? Cold, pale, clammy, diaphoretic or even cyanotic skin with decreased capillary refill time (skin and extremities) ? Decreased urine output (kidneys)

Answer:

Because hemorrhage is the most common cause of shock in the trauma patient, all shock in a trauma patient should be considered to be from hemorrhage until proven otherwise.The first priority is to_____for external sources of hemorrhage and control them as quickly and completely as possible.

Question 3: extramural pressure,

Answer:

Then direct pressure over the wound should be placed for a minimum of 3 to 5 minutes if using a hemostatic dressing and for 10 minutes if using plain gauze.

Question 4: 4. cells of the body

Answer:

shock may be classified as.

Question 5: aerobic metabolism

Answer:

occurs without the use of oxygen Question 6: In the primary assessment, time is not taken to measure a ventilatory rate. Instead, ventilations should be estimated to be ?

Answer:

slow, normal, fast, or very fast.

Question 7: primary assessment

Answer:

These functions are managed in the trauma patient by the

following actions:

? Maintaining an adequate airway and ventilation, thus providing adequate oxygen to the RBCs ? Assisting ventilation through the judicious use of supplemental oxygen ? Maintaining adequate circulation, thus perfusing tissue cells with oxygenated blood Question 8: Direct hand pressure or a pressure dressing, applied directly over a bleeding site,

Answer:

Fluid leak =Transmural pressure x Size of hole in vessel wall

Question 9: 3

Answer:

The classic findings of shock are obvious and include tachycardia (heart rate greater than 120 beats/ minute), tachypnea (ventilatory rate of 30 to 40 breaths/ minute), and severe anxiety or confusion

Question 10: is a helpful diagnostic sign that can

also be used to monitor the progress of resuscitation.

Answer:

Capillary refilling time

Question 11: anaerobic metabolism

Answer:

the patient's airway is patent and that breathing and circula tion are adequate-is the major emphasis of the ?

Question 12: Hypovolemic shock

Answer:

_____ shock (or vasogenic) shock is related to abnormality in vascular tone arising from several different causes.

Question 13: may be associated with up

to 2 to 4 units (1,000 to 2,000 ml) of blood loss into a thigh.This injury alone could potentially result in the loss of 30% to 40% of an adult's blood volume, resulting in decompensated hypovolemic shock

Answer:

femoral fracture Question 14: Hypovolemia produces cold, clammy, pale, or cyanotic skin and delayed capillary refilling time. In neurogenic shock the patient has warm , dry skin, especially below the area of injury

Answer:

Cardiogenic Shock 2 catigories

Question 15: Three Critical Points # 1

Answer:

First, when managing a wound with an impaled object, pressure should be applied on either side of the object rather than over the object

Question 16: Three Critical Points #2

Answer:

Second, if hands are required to perform other lifesaving tasks, a pressure (compression) dressing can be created using gauze pads and an elastic roller bandage or a blood pressure cuff inflated until hemorrhage stops. This dressing is placed directly over the bleeding site.Question 17: _______ shock also displays decreased systolic and diastolic pressures, but the pulse pressure remains normal or is widened

Answer:

Neurogenic

Question 18: A good sign of adequate resuscitation is a warm, dry, pink?

Answer:

toe Question 19: Measurement of an accurate set of vital signs is one of the first steps in the _____

Answer:

secondary assessment Question 20: data from the military experience suggest that appropriately applied tourniquets could potentially have prevented 7 of _____combat deaths.''"®

Answer:

100 Question 21: A fast ventilatory rate is a concern and should serve as an impetus to?

Answer:

search for the cause of shock.

Question 22: Patients in need of

immediate management of their airway include those with the

following conditions, in order of importance:

Answer:

• Patients who are not breathing

• Patients who have obvious airway compromise
