Which of the following are clinical manifestations of anaphylaxis? select all that apply
Hypertension
Angioedema
Petechiae
Bronchospasm
Correct Answer : B,D
A. Hypertension: Anaphylaxis often leads to a rapid drop in blood pressure (hypotension) rather than hypertension. Hypotension is a more common symptom because of the severe vasodilation that occurs during anaphylactic reactions.
B. Angioedema: Yes, angioedema is a common clinical manifestation of anaphylaxis. Angioedema involves swelling of the deeper layers of the skin, often around the eyes and lips. It can also affect the throat, which can be life-threatening due to airway obstruction.
C. Petechiae: Petechiae are small red or purple spots that appear on the skin and are caused by bleeding into the skin's tissues. They are not a typical manifestation of anaphylaxis.
D. Bronchospasm: Yes, bronchospasm is a hallmark clinical manifestation of anaphylaxis. It involves the sudden constriction of the airways, leading to difficulty in breathing and wheezing.

Correct Answer is A
Explanation
A. Macrophage: This is the correct answer. An activated monocyte is also known as a macrophage. Monocytes are white blood cells that can mature into macrophages when they move into tissues. Macrophages play a crucial role in the immune system by phagocytosing (engulfing and digesting) pathogens and cellular debris.
B. Lymphocyte: Lymphocytes are another type of white blood cell that plays a central role in the immune system. They include B cells, T cells, and natural killer cells. Lymphocytes are primarily involved in adaptive immune responses, such as antibody production (B cells) and cell-mediated immune responses (T cells).
C. Plasma Cell: Plasma cells are a type of B cell that produces antibodies (immunoglobulins). They are involved in the adaptive immune response, specifically in the production of antibodies that target specific pathogens.
D. Polymorphonuclear Leukocyte: This term typically refers to a group of white blood cells that have a multi-lobed nucleus. Neutrophils, eosinophils, and basophils are examples of polymorphonuclear leukocytes. They are involved in innate immune responses, including the phagocytosis of pathogens.
Correct Answer is A
Explanation
A. IgG: Immunoglobulin G (IgG) is the most abundant antibody in the bloodstream and represents about 75% of all the antibodies in the body. It provides long-term immunity because it can persist in the bloodstream for a long time. IgG antibodies are involved in secondary immune responses and are capable of crossing the placenta, providing passive immunity to newborns.
B. IgE: Immunoglobulin E (IgE) is associated mainly with allergic reactions. When the body is exposed to an allergen, it triggers the release of IgE, leading to the symptoms of an allergic response, such as sneezing or itching.
C. IgM: Immunoglobulin M (IgM) is the largest antibody and is usually the first antibody produced during an initial exposure to an antigen. It is particularly effective at agglutination (clumping together) of pathogens.
D. IgA: Immunoglobulin A (IgA) is found in high concentrations in mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract. It provides localized defense against pathogens. IgA antibodies are also found in saliva, tears, and breast milk, providing immunity to infants.
