(a)

Summary Introduction

To explain: The rationale for pruritus (itchy skin) associated with anaphylaxis.

Introduction: Anaphylaxis is the severe and potential life-threatening hypersensitivity reaction that occurs within seconds or minutes of exposure to allergens. This anaphylactic shock results in decreased blood pressure, obstruction of airway, and causes severe hypoxia. Common allergens that cause anaphylaxis include gloves, insect stings, penicillin administration, consumption of nuts or shellfish, or local anesthetic injections.

(b)

Summary Introduction

To explain: The rationale for difficulty in talking and breathing associated with anaphylaxis.

Introduction: Anaphylaxis is the severe and potential life-threatening hypersensitivity reaction that occurs within seconds or minutes of exposure to allergens. This anaphylactic shock results in decreased blood pressure, obstruction of airway, and causes severe hypoxia. Common allergens that cause anaphylaxis include gloves, insect stings, penicillin administration, consumption of nuts or shellfish, or local anesthetic injections.
