Which of the following symptoms are unique to anaphylactic shock?

Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock blood pressure drops suddenly and the airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.

Which of the following injuries would most likely cause non hemorrhagic hypovolemic shock?

Hemorrhagic shock, be it from internal or external bleeding, is the most common cause of hypovolemic shock (Table 106-2). Nonhemorrhagic hypovolemic shock can be caused by severe dehydration owing to massive urinary or gastrointestinal fluid losses.

Which of the following conditions would make you suspect shock?

Shock may result from trauma, heatstroke, blood loss, an allergic reaction, severe infection, poisoning, severe burns or other causes. When a person is in shock, his or her organs aren’t getting enough blood or oxygen.

Which of the following is likely to result in hypovolemic shock?

Hypovolemic shock results from significant and sudden blood or fluid losses within your body. Blood loss of this magnitude can occur because of: bleeding from serious cuts or wounds. bleeding from blunt traumatic injuries due to accidents.

What do you do for anaphylactic shock?

If someone appears to be going into anaphylactic shock, call 911 and then:

  • Get them into a comfortable position and elevate their legs. This keeps blood flowing to the vital organs.
  • If they have an EpiPen, administer it immediately.
  • Give them CPR if they aren’t breathing until the emergency medical team arrives.

Which of the following would be the most likely cause of neurogenic shock?

The blood pools in your blood vessels, and your blood pressure drops significantly. The cause of neurogenic shock is usually a spinal cord injury. When the nerves in the spinal cord are damaged, they stop sending messages to the nerves that control other functions in the body.

Which of the following would most likely result in hemorrhagic shock quizlet?

circular muscular walls that regulate blood flow through the capillaries. Which of the following would MOST likely result in hemorrhagic shock? Liver laceration.

What is the most common cause of hypovolemic shock?

Hypovolemic shock occurs as a result of either blood loss or extracellular fluid loss. Hemorrhagic shock is hypovolemic shock from blood loss. Traumatic injury is by far the most common cause of hemorrhagic shock.

What causes non hemorrhagic shock?

However, a number of important non-hemorrhagic causes can occur. These include inadequate oxygenation, mechanical obstruction (eg, cardiac tamponade, tension pneumothorax), neurologic dysfunction (eg, high spinal cord injury), and cardiac dysfunction [1].

What is hemorrhagic shock?

Hemorrhagic shock is a form of hypovolemic shock in which severe blood loss leads to inadequate oxygen delivery at the cellular level. If hemorrhage continues unchecked, death quickly follows.

What are the effects of shock?

The symptoms of shock include cold and sweaty skin that may be pale or gray, weak but rapid pulse, irritability, thirst, irregular breathing, dizziness, profuse sweating, fatigue, dilated pupils, lackluster eyes, anxiety, confusion, nausea, and reduced urine flow.

Which of the following injuries would cause obstructive shock?

Obstructive shock can be caused by cardiac (pericardial) tamponade, which is an abnormal build-up of fluid in the pericardium (the sac around the heart) that compresses the heart and stops it from beating properly, or pulmonary embolism (a blood clot in the pulmonary artery, blocking the flow of blood to the lungs)

What causes hemorrhagic shock?

Hemorrhagic shock is caused by the loss of both circulating blood volume and oxygen-carrying capacity. The most common clinical etiologies are penetrating and blunt trauma, gastrointestinal bleeding, and obstetrical bleeding.

What happens hypovolemic shock?

Hypovolemic shock is an emergency condition in which severe blood or other fluid loss makes the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working.

What happens to blood pressure during hypovolemic shock?

A narrow pulse pressure in a hypovolemic shock patient indicates a decreasing cardiac output and an increasing peripheral vascular resistance. The decreasing venous volume from blood loss and the sympathetic nervous system attempt to increase or maintain the falling blood pressure through systemic vasoconstriction.

What 3 things are likely to be seen in an anaphylactic reaction?

The symptoms include:

  • feeling lightheaded or faint.
  • breathing difficulties such as fast, shallow breathing.
  • wheezing.
  • a fast heartbeat.
  • clammy skin.
  • confusion and anxiety.
  • collapsing or losing consciousness.

What is a anaphylactic shock?

Anaphylactic shock is a rare but severe allergic reaction that can be deadly if you don’t treat it right away. It’s most often caused by an allergy to food, insect bites, or certain medications. A shot of a drug called epinephrine is needed immediately, and you should call 911 for emergency medical help.

What happens after an anaphylactic reaction?

Circulatory system. During anaphylaxis, small blood vessels (capillaries) begin to leak blood into your tissues. This can cause a sudden and dramatic drop in blood pressure. Other symptoms include a rapid or weak pulse and heart palpitations.

Which of the following are most likely signs of inadequate circulation?

Common symptoms include:

  • numbness and tingling in the hands and feet.
  • cold hands and feet.
  • swelling in the feet, ankles, and legs.
  • memory loss and difficulty concentrating.
  • digestive issues.
  • fatigue.
  • joint and muscle cramping.
  • skin color changes.

Which of the following vital signs would most indicate neurogenic shock?

Patients in neurogenic shock usually present with a systolic blood pressure of approximately 70 mm Hg or lower and a pulse below 60.

Which of the following is a clinical characteristic of neurogenic shock?

Bradyarrhythmia, hypotension, flushed warm skin are the classic signs associated with neurogenic shock.

Which of the following is the result of blood flow to the brain being stopped quizlet?

Figure 1. A stroke is a sudden interruption of the blood supply to the brain. The middle cerebral artery is most often blocked during a stroke.

Which of the following has the greatest impact on producing injury?

Which of the following has the greatest impact on producing injury? speed; The energy that is available to cause injury doubles when an object’s weight doubles, but it quadruples when speed doubles.

Which of the following is in decompensated shock?

Patients with decompensated shock have cold, clammy extremities; a feeble or absent peripheral pulse; severe tachycardia (or bradycardia in late shock); a PP < 20 mm Hg; or a low systolic blood pressure (SBP) for age.

What is the effect of hypovolemic shock on the blood vessels and the heart?

The cardiovascular system initially responds to hypovolemic shock by increasing the heart rate, increasing myocardial contractility, and constricting peripheral blood vessels.

What causes blood loss?

Blood loss can be acute and rapid or chronic. Some causes of rapid blood loss include surgery, childbirth, and trauma. Chronic blood loss is more often responsible for anemia. It can result from a stomach ulcer, cancer, or another type of tumor.

What is the cause of hypovolemic shock that occurs during dialysis?

At the time dialysis-induced hypotension occurred or before, there was no sharp decrease in blood volume nor any change in the plasma refilling rate. This suggested that this hypotension is caused by a sudden breakdown of the blood pressure support mechanism compensating for decreased blood volume.

What clinical manifestations would indicate maternal hypovolemic shock?

Decreased or no urine output. Generalized weakness. Pale skin color (pallor)Rapid breathing.
