Correct Answer is ["B","C","D","F"]
Explanation
Choice A rationale
Increased awareness is not a manifestation of anaphylactic shock. Anaphylactic shock typically causes confusion or loss of consciousness due to decreased blood flow to the brain.
Choice B rationale
Chest pain can occur during anaphylactic shock due to the body’s severe allergic reaction and the strain it places on the cardiovascular system.
Choice C rationale
Dyspnea, or difficulty breathing, is a common manifestation of anaphylactic shock. The airways can become constricted, making it hard to breathe.
Choice D rationale
Angioedema, or swelling of the deeper layers of the skin, often occurs during anaphylactic shock. It can affect the face, throat, and other areas.
Choice E rationale
Hypertension, or high blood pressure, is not a typical manifestation of anaphylactic shock. Anaphylactic shock usually causes hypotension, or low blood pressure.
Choice F rationale
Urticaria, or hives, is a common skin reaction during anaphylactic shock. It presents as red, itchy welts on the skin.
Correct Answer is A
Explanation
Choice A rationale
Shutting off the intravenous infusion is the immediate action to take when a client reports difficulty swallowing during infliximab infusion. This could indicate an infusion reaction or anaphylaxis, which requires immediate cessation of the infusion to prevent further complications.
Choice B rationale
Notifying the primary health care provider is important, but the immediate action should be to stop the infusion to prevent further adverse reactions.
Choice C rationale
Having the client take deep breaths and try to relax is not appropriate in this situation, as it does not address the potential infusion reaction or anaphylaxis.
Choice D rationale
Obtaining a prescription for oral diphenhydramine may be part of the treatment for an infusion reaction, but the immediate action should be to stop the infusion. .
