TRAUMA- (Ch. 31 Bleeding & Blood Administration)

Class II hypovolemic shock caused by hemorrhagic trauma would be characterized by which amount of blood loss from a patient who weighs 154 pounds?

15% to 30%

Which of the following factors directly affect cardiac output?

Stroke volume and pulse rate

The most significant factor that determines how well the body compensates for blood loss is:

the period of time over which the blood is lost.

Arterial bleeding may require how many minutes or more of direct pressure to form a clot?

5 minutes

After managing an internal hemorrhage, it is important to monitor and record vital signs at least every:

5 minutes.

Infants and children who experience hemorrhaging may have a normal blood pressure until they have lost what percentage of their blood volume?

50%

The initial stage of hemorrhagic shock is characterized by which of the following signs or symptoms?

Low circulating blood volume with minimal signs of hypoperfusion

Decompensated shock in the adult is characterized by:

falling blood pressure.

When packing a wound, you should hold firm, direct manual pressure on the wound for at least:

3 minutes.

Which of the following types of shock is caused by poor blood vessel function?

Anaphylactic

A patient exhibiting signs of shock has a markedly elevated respiratory rate, cold and pale skin, diminished urine output, and a thready pulse with heart rate of 125 beats/min. This patient would be characterized as being in which class of hypovolemic shock?

Class III

Which component gives red blood cells their red color?

Hemoglobin

Which of the following is true of bleeding from an open vein?

It is darker red in color.

Much of the bleeding associated with unsplinted fractures continues because:

bone ends will continue to move and destroy partially formed clots.

External bleeding would be the most difficult to control in a patient with a large laceration to the:

carotid artery.

if you suspect a skull fracture, you should:

cover the bleeding site loosely with a sterile gauze pad.

Most external hemorrhage can be controlled with a combination of:

direct pressure and pressure dressings.

If you suspect internal bleeding during the primary assessment, you should:

keep the patient warm and administer oxygen.

A trauma patient with suspected internal hemorrhage and inadequate breathing requires:

ventilation assistance and rapid transport.
