Which of the following is NOT a sign of good perfusion?
- A.
Pink, warm, and dry skin
- B.
Confused mental status
- C.
Alert and normal mental status
- D.
Vital signs within normal limits
Correct Answer
B. Confused mental statusExplanation
Confused mental status is not a sign of good perfusion because it indicates that there may be inadequate blood flow to the brain, leading to altered mental status. Good perfusion is typically indicated by pink, warm, and dry skin, an alert and normal mental status, and vital signs within normal limits.Rate this question:

If left untreated, _________ can lead to shock.
- A.
Bleeding
- B.
High blood pressure
- C.
A rapid respiration
- D.
An altered mental status
Correct Answer
A. BleedingExplanation
If left untreated, bleeding can lead to shock. When a person experiences significant bleeding, they can lose a large amount of blood, which can lead to a decrease in blood pressure and inadequate blood flow to vital organs. This can result in shock, a life-threatening condition characterized by a rapid heart rate, low blood pressure, confusion, and organ failure. Prompt medical intervention is necessary to control bleeding and prevent shock.Rate this question:

A contusion often results in:
- A.
Abrasion
- B.
Amputation
- C.
Avulsion
- D.
Hematoma
- E.
Laceraction
Correct Answer
D. HematomaExplanation
A contusion often results in a hematoma. A hematoma is a localized collection of blood outside the blood vessels, usually caused by an injury or trauma. When a contusion occurs, blood vessels underneath the skin are damaged, leading to bleeding and the formation of a hematoma. This can cause swelling, pain, and discoloration of the affected area.Rate this question:

In many cases, patients with internal bleeding will require ___________ in order to survive.
- A.
Late detection of shock
- B.
Surgical intervention
- C.
Ongoing assessments
- D.
A rapid trauma assessment
Correct Answer
B. Surgical interventionExplanation
Patients with internal bleeding often require surgical intervention in order to stop the bleeding and prevent further complications. Surgery may involve repairing damaged blood vessels, removing blood clots, or performing other necessary procedures to address the source of the bleeding. Without surgical intervention, the patient's condition may worsen, leading to severe blood loss, organ damage, or even death. Therefore, surgical intervention is crucial for the survival of patients with internal bleeding.Rate this question:

This is type of shock is caused by a sudden decrease in body fluids.
- A.
Anaphylactic
- B.
Neurogenic
- C.
Septic
- D.
Hypovolemic
Correct Answer
D. HypovolemicExplanation
Hypovolemic shock occurs when there is a sudden decrease in body fluids, specifically blood volume. This can be caused by severe bleeding, dehydration, or fluid loss from burns or excessive sweating. The decrease in blood volume leads to inadequate perfusion of organs and tissues, resulting in symptoms such as low blood pressure, rapid heart rate, and confusion. Treatment involves replacing the lost fluids and identifying and addressing the underlying cause of the fluid loss.Rate this question:

What is NOT a sign/symptom of shock.
- A.
Tachycardia
- B.
Thirst
- C.
Vomiting
- D.
Pink, warm, and moist skin
Correct Answer
D. Pink, warm, and moist skinExplanation
Pink, warm, and moist skin is not a sign/symptom of shock. Shock is a life-threatening condition in which the body's organs and tissues do not receive enough oxygen and nutrients. Tachycardia, or a rapid heart rate, is a common sign of shock as the body tries to compensate for the lack of blood flow. Thirst may also be present as the body tries to replace lost fluids. Vomiting can occur due to the body's stress response. However, pink, warm, and moist skin is not typically seen in shock as the body's blood vessels constrict and the skin becomes pale, cool, and clammy.Rate this question:
-
- 7.
When the body can no longer compensate for the blood loss, the pulse_______ and the blood pressure _________.
- A.
Increases, increases
- B.
Decreases, increases
- C.
Decreases, decreases
- D.
Increases, decreases
Correct Answer
D. Increases, decreasesExplanation
When the body can no longer compensate for the blood loss, the pulse increases because the heart is trying to pump more blood to compensate for the loss. At the same time, the blood pressure decreases because there is less blood volume in the vessels, leading to a decrease in pressure.Rate this question:

2,500
- B.
4,900
- C.
3,600
- D.
4,200
- E.
3,500
Correct Answer
B. 4,900Explanation
An adult weighing 70 kg has approximately 4,900 ml of blood. This is the average blood volume for an adult of that weight. Blood volume can vary depending on factors such as age, gender, and overall health, but 4,900 ml is a reasonable estimate.Rate this question:

It can be life threatening for an adult patient to lose more then ___ liters of blood.
- A.
9
- B.
22
- C.
16
- D.
4
- E.
1
Correct Answer
E. 1Explanation
Losing more than 1 liter of blood can be life-threatening for an adult patient. Blood loss can lead to hypovolemic shock, which occurs when there is a significant decrease in blood volume. This can cause a drop in blood pressure, reduced oxygen delivery to vital organs, and potentially organ failure. Therefore, it is crucial to monitor and manage blood loss in order to prevent life-threatening complications.Rate this question:

The largest artery in the body is the:
- A.
Vena cava
- B.
Femoral artery
- C.
Aorta
- D.
Pulmonary artery
Correct Answer
C. AortaExplanation
The aorta is the largest artery in the body. It is responsible for carrying oxygenated blood from the heart to the rest of the body. The vena cava is a large vein that carries deoxygenated blood back to the heart. The femoral artery is a major artery in the thigh that supplies blood to the lower limbs. The pulmonary artery carries deoxygenated blood from the heart to the lungs. Therefore, the correct answer is the aorta.Rate this question:

- 11.
The following are vessels that bleed EXCEPT:
- A.
Capillaries
- B.
Arteries
- C.
Avulsions
- D.
Veins
Correct Answer
C. AvulsionsExplanation
Avulsions do not bleed because they refer to the tearing away of a body part or structure, usually due to trauma or injury. While avulsions can cause bleeding in the surrounding tissues, the actual avulsed body part or structure does not have blood vessels of its own and therefore does not bleed. On the other hand, capillaries, arteries, and veins are all types of blood vessels that can bleed when injured or damaged.Rate this question:

There are ____ major pressure points.
- A.
9
- B.
3
- C.
5
- D.
2
- E.
4
Correct Answer
E. 4Explanation
The correct answer is 4 because the question asks for the number of major pressure points, and out of the given options, 4 is the only number that represents a plausible number of major pressure points.Rate this question:
-
- 13.
_________ may help control bleeding because they can maintain a constant pressure when applied properly.
- A.
Oxygen
- B.
Tourniquet
- C.
Sam splint
- D.
Air splints
Correct Answer
B. TourniquetExplanation
A tourniquet is effective in controlling bleeding by exerting constant pressure on the injured area when properly applied. This pressure helps to constrict blood vessels, reducing blood flow to the wound. Tourniquets are crucial in emergency situations to prevent excessive blood loss and stabilize the patient's condition.Rate this question:

The two factors that determine the severity of blood loss are:
- A.
Time and quantity
- B.
Body size and injury
- C.
Body size and time
- D.
Time and injury
Correct Answer
D. Time and injuryExplanation
The severity of blood loss is determined by two factors: time and injury. Time refers to how quickly the blood is lost, as a rapid loss can lead to more severe consequences. Injury refers to the extent and location of the damage, as a more severe injury can result in greater blood loss. Therefore, both time and injury play a significant role in determining the severity of blood loss.Rate this question:

Bleeding from _______ is often steady and flowing and appears darker in color.
- A.
Capillaries
- B.
Veins
- C.
Venules
- D.
Arteries
Correct Answer
B. VeinsExplanation
Bleeding from veins is often steady and flowing and appears darker in color because veins carry deoxygenated blood back to the heart. The deoxygenated blood is darker in color compared to oxygenated blood, which is carried by arteries. Capillaries are tiny blood vessels that connect arteries and veins, while venules are small veins. Arteries carry oxygenated blood away from the heart.Rate this question:

1. Which of the following is NOT an indication for the PASG:
- A.
Evisceration
- B.
Suspected pelvic fracture with signs of shock
- C.
Suspected AAA
- D.
Lower extremity fractures
Correct Answer
A. EviscerationExplanation
The PASG (Pneumatic Anti-Shock Garment) is a medical device used to stabilize patients with severe hemorrhage or shock. It is contraindicated in cases of evisceration, which refers to the protrusion of organs through a wound or opening in the abdominal wall. Evisceration requires immediate medical attention and surgical intervention, and the application of the PASG could potentially worsen the condition. Therefore, evisceration is not an indication for the use of the PASG.Rate this question:

Hypoperfusion is often used to mean:
- A.
Inadequate perfusion
- B.
Bleeding
- C.
Internal hemorrhage
- D.
Adequate circulation
Correct Answer
A. Inadequate perfusionExplanation
Hypoperfusion refers to a condition where there is a decrease in blood flow to the organs and tissues, resulting in inadequate perfusion. This means that the organs and tissues are not receiving enough oxygen and nutrients to function properly. It can be caused by various factors such as low blood volume, heart failure, or blood vessel constriction. Bleeding and internal hemorrhage, on the other hand, refer specifically to the loss of blood from blood vessels, which can lead to hypoperfusion if not addressed. Adequate circulation, on the contrary, implies that there is sufficient blood flow to meet the needs of the body.Rate this question:
