Q

Choose:

If blood is not circulated adequately through the body’s capillaries, cells become starved for oxygen and nutrients, and overloaded with carbon dioxide and waste products.

This condition is known as:

A. cardiac compromise.

B. hypoperfusion.

C. circulatory depression.

D. hypotension.

A

B

under some conditions, blood does not circulate adequately through all the body’s capillaries

chief result of inadequate circulation is a state of profound depression of cell perfusion, called shock (or hypoperfusion)

cells become starved for oxygen (hypoxia) and nutrients, and become overloaded with carbon dioxide and other waste products

Q

Answer:

How does the vascular system control temperature regulation?

A

The body’s mechanism to conserve heat is to expand (dilate) or narrow (constrict) the blood vessels.

dilation of the blood vessels contributes to heat dissipation, whereas constriction of the blood vessels preserves core temperature by decreasing heat dissipation

A. 45-year-old motor vehicle crash victim with pale, cool, skin and tachycardia

B. 16-year-old female with a possible traumatic brain injury presenting with altered mental status and low blood pressure

C. 36-year-old fall victim with absent peripheral pulses

D. 52-year-old assault victim with bilaterally dilated pupils and cyanosis

A

A

initial presentation of shock symptoms include pale/cool/clammy skin, tachycardia, and tachypnea

vital signs will deteriorate, with low blood pressure, thirst, dilated pupils, and cyanosis as shock progresses to late signs

45
Q

Choose:

Your patient is a 49-year-old female with complaints of shortness of breath and generalized weakness. On examination, you note that she has extensive crackles in her lungs, swelling of her feet and ankles, and difficulty in breathing when lying down. This is troublesome for her because she gets lightheaded when sitting up, because of her low blood pressure.

You would classify her shock as:

A. neurogenic shock.

B. anaphylactic shock.

C. septic shock.

D. cardiogenic shock.

A

D

the patient’s signs and symptoms suggest congestive heart failure, indicating cardiogenic shock, because the pumping mechanism has been compromised

46
Q

Choose:

Which of the following would most likely lead to hypovolemic shock?

A. Open fracture of the hand

B. Subdural hematoma

C. Crush injury to the foot

D. Crush injury to the abdomen

A

D

hypovolemic shock is most often caused by significant blood loss due to trauma or internal hemorrhage from a medical cause (such as an AAA, GI bleed, or crush injuries to major body cavities, such as the chest or abdomen)

hypovolemic shock may also result from third-space losses such as fluid shifts into various body compartments, as in severe pancreatitis, or fluid loss from protracted vomiting

47
Q

Choose:

Your 55-year-old female patient is suffering from a rupturing abdominal aortic aneurysm, and is entering into the decompensating stage of shock.

What finding would not be an indicator of decompensated shock in this patient?

A. Cyanosis

B. Dilated pupils

C. Increased heart rate

D. Falling blood pressure

A

C

increased heart rate would be a sign of early, compensating shock (not an indicator of decompensated shock)

48
Q

Choose:

You are assessing a 53-year-old male with severe blood loss from a wound that is covered with a pressure bandage. Bleeding appears to have stopped. The patient’s pulse and respiration are elevated, but blood pressure is falling. The patient’s skin around the lips shows signs of cyanosis, and the patient’s pupils are dilated.

What is a sign that the patient has entered decompensated shock?

A. Cyanotic skin

B. Severe blood loss

C. Elevated pulse

D. Elevated respiration

A

A

cyanosis around the lips and nail beds is one of the signs of late shock (which would indicate the onset of decompensated shock)

B is wrong because severe blood loss alone does not indicate decompensated shock

C and D are wrong because an elevated pulse and respiration would be consistent with compensated shock

49
Q

Choose:

You are caring for a 28-year-old male patient who was involved in a motor vehicle crash. He has sustained a closed head injury and blunt-force trauma to his chest and abdomen, and is unconscious and in shock.

In what position should you transport him?

A. In a sitting position, because of his closed head trauma

B. In a reverse Trendelenburg position, because of the patient’s head trauma and pulmonary injury

C. In a left lateral position, to allow for vomiting and to prevent aspiration

D. In a supine position with sufficient spinal immobilization

A

D

shock position… also consider the MVC and need for immobilization

50
Q

Choose:

You are treating a 64-year-old female patient complaining of weakness and abdominal pain. You find the patient pale, cool, and diaphoretic, leaning against the wall adjacent to her toilet. You note the presence of bright, red blood in the toilet.

Based on these findings, what treatment option will improve the body’s ability to clot?

A. Cover the patient in a blanket to prevent hypothermia.

B. Request advanced life support assistance, so that intravenous fluids can be infused to replace lost blood volume.

C. Place the patient on high-flow oxygen via nonrebreather.

D. Transport the patient to the most appropriate facility as soon as possible.

A

A

(in addition to depleting the body’s energy stores) hypothermia may reduce the body’s ability to clot

keeping the patient warm may prevent heat loss (which contributes to hypothermia)

A

A bulky dressing that is held in place by a tightly wrapped bandage and is used to control bleeding is called a pressure dressing.

52
Q

Choose:

You arrive on scene to an 8-year-old male patient who fell while skating. He is responsive but is lying down on the pavement. As you assess the patient, you notice abrasions with self-controlled bleeding located on both his knees.

Based on your assessment, what type of external bleeding is this?

A. Arterial

B. Non-significant

C. Venous

D. Capillary

A

D

Slowly oozing blood that is a dark or intermediate color of red usually indicates damaged capillaries. In most cases, capillary bleeding is easily controlled. This type of bleeding often clots spontaneously.

53
Q

Choose:

Your 14-year-old male patient has fallen off his bike and scraped his arm. The bleeding is dark red and oozing slowly. This type of bleeding is usually from damaged:

A. arteries.

B. veins.

C. capillaries.

D. venules.

A

C

Slowly oozing blood that is a dark or intermediate color of red usually indicates damaged capillaries. In most cases, capillary bleeding is easily controlled. This type of bleeding often clots spontaneously. However, if a large body surface is involved, bleeding may be profuse, and the threat of infection is great.

54
Q

Choose:

You are treating a 43-year-old female who was hunting with a pistol. When she sat down in the outhouse, her gun went off and created a large hole in her right femur, which is now severely spurting blood.

What is the most appropriate method of bleeding control for this injury if direct pressure fails?

A. Direct pressure and elevation

B. Looking for a pressure point to apply

C. Application of ice on the wound

D. Application of a tourniquet

A

D

when a patient has a severe extremity injury (as in this case in which the blood is spurting from an artery), the most effective bleeding control method will be a tourniquet.

55
Q

Choose:

If you find a major bleed during your initial assessment of the patient, you should immediately [BLANK].

A

If you find a major bleed during your initial assessment of the patient, you should immediately apply direct pressure to the site with your gloved hand.

major bleeds must be stopped ASAP before continuing primary assessment

56

70
Q

Choose:

You are treating a 42-year-old male complaining of chest pain and shortness of breath. You notice that he appears pale, cool, and sweaty.

What is the most likely reason for these findings?

A. The patient’s pain receptors are causing his vessels to expand and dilate.

B. Blood vessels are dilating, causing inadequate gas exchange.

C. Blood vessels constrict in response to sympathetic stimulation, causing a decrease in blood flow to the skin.

D. The body is attempting to rid waste products through the skin as well as the kidneys.

A

C

this is definitely correct answer according to everywhere online

my best guess in explaining this answer is that patient is having AMI which apparently causes sympathetic stimulation

according to Wikipedia snippet from Google, sympathetic stimulation “causes vasoconstriction of most blood vessels, including many of those in the skin, the digestive tract, and the kidneys”

Finding arterial bleeding quickly is very important in assessing a patient.

Which statement about arterial bleeding is correct?

A. Clot formation takes place rapidly.

B. Arterial bleeding is often rapid and profuse.

C. Arterial bleeding is the least difficult type of bleeding to control.

D. Arterial bleeding causes the blood pressure to rise.

A

B

Arterial bleeding is often rapid and profuse. Blood in the arteries is maintained under high pressure by thick, muscular walls. Therefore, arterial hemorrhage is more difficult to control. Clot formation is also difficult because of this pressure.

85
Q

Choose:

You are treating a 58-year-old male whose throat was slashed by an attacker standing behind him during a street hold-up.

When a large bleeding vein in the neck sucks in an air bubble, or embolism, this can cause:

A. an evisceration.

B. heart stoppage.

Q

Choose:

When attempting to control a deep laceration across the entire right buttock of a 22-year-old ski racer, you note that the cut goes down to the bone and will not stop bleeding. The best treatment would be to utilize [BLANK] while beginning to transport the patient by MEDEVAC to the regional trauma center.

A. elevation of the wound

B. hemostatic gauze into the wound

C. ice packs into the wound

D. a commercial tourniquet

A

B

the key is to stuff hemostatic gauze directly into the bleeding wound, apply a pressure bandage, and take the patient to the regional trauma center

you will not be able to use a tourniquet because the wound is on the buttocks

you would not stuff cold packs directly into the wound or elevate it

103
Q

Choose:

Your patient was cutting trees on his property with a manual bow saw when it slipped from its track and lacerated his right upper thigh. He is conscious, alert, and oriented with a 6-inch long laceration visible with moderate to severe dark red flowing blood present. His family is applying pressure to the femoral artery without successfully controlling the hemorrhage.

What type of bleeding do you suspect and how should you attempt to control it?

A. Arterial bleeding; direct pressure and pressure points

B. Venous bleeding; direct pressure with bulky trauma dressing

C. Capillary bleeding; tourniquet above the wound

D. Arterial bleeding; tourniquet over the wound

A

B

Venous bleeding presents as dark red due to the waste products that are contained within the blood from the lungs. It can be life-threatening if it remains uncontrolled. Direct pressure should be attempted first followed by a tourniquet if it is unsuccessful.

104
Q

Choose:

Which of the following body cavities is not spacious enough to allow for an internal bleed to progress to the point of causing hypotensive shock?

A. The thorax

B. The proximal leg

C. The skull

D. The abdomen

A

C

The skull is the only cavity in the body that is encased entirely by immovable bone. In addition, it is (ideally) filled with brain matter, making infiltration by large amounts of fluid impossible. Another way to look at it is by considering that since the other cavities (the incorrect answers) can expand while the skull cannot, the biggest problem with intracranial bleeding is increased intracranial pressure causing disturbances in homeostasis, not the actual amount of blood lost into it.

105
Q

Choose:

You arrive on the scene of a reported shooting after the police have cleared the scene. A victim’s mental status has been declining at a rapid rate. Police report that he has become pale, confused, and seems to be breathing rapidly. You note an entrance wound on the left abdomen that is oozing a significant quantity of blood.

Which of the following would you also anticipate finding during the primary survey?

A. Shallow respirations

B. Bradycardia

C. Weak or absent peripheral pulses

D. Abdominal distention from internal bleeding

A

C

Severe blood loss presents with cold and pale skin, rapid breathing, tachycardia/bradycardia, confusion, weakness, cyanosis, loss of consciousness, and diminished peripheral pulses. THE MOST RELIABLE SIGN OF SEVERE BLOOD LOSS IS DIMINISHED OR ABSENT PULSES IN THE ANKLES AND WRISTS. The lack of these pulses implies the patient’s systolic BP is below 80. A carotid pulse is palpable until systolic goes below 60.
