RhoGAM can be provided for pregnant patients at risk for an incompatible Rh factor pregnancy (second birth).

3

What is a field block?

A field block is when local anesthesia is applied approximately 1 cm around the wound margin.

4

When listening to lung sounds, what is hyper-resonance suggestive of?

Hyper-resonance is suggestive of pneumothorax / tension pneumothorax.

5

As the body shunts blood, what organs maintain the highest priority of blood flow?

As the body shunts blood, the brain, heart and kidneys maintain the highest priority of blood flow.

6

What action should be done prior to undergoing primary closure of a wound?

Prior to undergoing primary closure, a functionality assessment should be completed.

***assess PMS distal to the wound***

7

When will hasty tourniquets, which require repositioning, be converted?

Hasty tourniquets, which require repositioning, will be converted at the EARLIEST opportunity PRIOR to evacuation.

8

What are the main components of blood?

The main components of blood are:

1 - Plasma: transports cells, nutrients, waste and heat
2 - Formed elements: WBCs and RBCs
3 - Platelets

9

What areas of the body are considered to be non-compressible in terms of hemorrhage control?

The areas of the body are considered to be non-compressible in terms of hemorrhage control are:

1 - Chest (upper torso)
2 - Abdomen (mid torso)
3 - Pelvis (lower torso)

10

Where is body heat generated?

Body heat is generated (typically) within the muscles during muscle movement.

11

As the body shunts blood, what organs have the lowest priority of blood flow?

As the body shunts blood the skin, muscles and bones have the lowest priority of blood flow.

12

Ecchymosis (bruising), hemoptysis (coughing up bleeding), rectal bleeding and hematemesis (bloody vomiting) are all indications of what?

Ecchymosis (bruising), hemoptysis (coughing up bleeding), rectal bleeding and hematemesis (bloody vomiting) are all indications of non-compressible hemorrhage (((internal bleeding))).

13

When listening to lung sounds, what is hypo-resonance suggestive of?

Hypo-resonance is suggestive of hemothorax.

14

What is the formula for calculating the oxygen flow rate in a "D" sized cylinder?

The formula for calculating the oxygen flow rate in a "D" sized cylinder is:

1. (Current PSI) - 200 = Usable PSI
2. Usable PSI x 0.16 = Usable liters
3. Usable liters / flow rate (LPM) = Minutes of O2 remaining

15

What is the approximate amount of blood a typical adult casualty can lose into each side of the chest?

The approximate amount of blood a typical adult casualty can lose into each side of the chest is 1500 mL.

16

________ is the pressure exerted by the concentration of solutes on one side of a membrane.

Osmotic pressure is the pressure exerted by the concentration of solutes on one side of a membrane.

***Water and solutes will flow from an area of higher concentration to an area of lower concentration***

17

Which anesthesia procedure is commonly used in part for treatment for injuries to digits, and/or finger and toe nail removal?

The regional (digital nerve block) anesthesia procedure is commonly used in part for treatment for injuries to digits, and/or finger and toe nail removal.

1. Hypotension (narrowing pulse pressure)
2. Muffled heart sounds
3. Distended neck veins

22

As the body shunts blood, what organs maintain the second highest priority of blood flow?

As the body shunts blood the intestines, liver stomach and spleen maintain the second highest priority of blood flow.

26

What is secondary closure?

Secondary closure is when the wound is left open and closes gradually through the natural healing process.

27

For patients suffering from shock, what leads to acidosis eventually?

For patients suffering from shock, excessive lactic acid buildup from anaerobic metabolism (due to lack of oxygen in muscles) leads to acidosis.
