Which of the following allergic reactions results in decreased blood pressure and shortness of breath? Correct Answer Anaphylaxis

The correct answer is Anaphylaxis.

• Anaphylaxis is allergic reactions that result in decreased blood pressure and shortness of breath.

Key Points

• Anaphylaxis is a severe, potentially life-threatening allergic reaction.
• It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.
• Anaphylaxis causes your immune system to release a flood of chemicals that can cause you to go into shock your blood pressure drops suddenly and your airways narrow, blocking breathing.
• Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.
• Common triggers include certain foods, some medications, insect venom, and latex.
• Anaphylaxis requires an injection of epinephrine and a follow-up trip to an emergency room.
• If you don't have epinephrine, you need to go to an emergency room immediately.
• If anaphylaxis isn't treated right away, it can be fatal. 

Additional Information

• Hives, also known as urticaria, are itchy, raised welts that are found on the skin.
  • They are usually red, pink, or flesh-colored, and sometimes they sting or hurt.
  • In most cases, hives are caused by an allergic reaction to a medication or food or a reaction to an irritant in the environment.
• Asthma is a condition in which your airways narrow and swell and may produce extra mucus.
  • This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out, and shortness of breath.
• Hay fever, also called allergic rhinitis, causes cold-like signs and symptoms, such as a runny nose, itchy eyes, congestion, sneezing, and sinus pressure.
  • But unlike a cold, hay fever isn't caused by a virus.
