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 B
Explanation
A. "You have developed urticaria in response to something in your environment."
This statement is incorrect. Urticaria refers to hives, a skin rash usually caused by an allergic reaction, infection, or stress. It's not necessarily indicative of an autoimmune disease.
B. "Your immune system is creating antibodies that are destroying your own cells."
This statement is correct. Autoimmune diseases involve the immune system mistakenly attacking the body's own cells and tissues, leading to various health issues.
C. "Your immune system is not able to create antibodies to help you fight infection."
This statement is incorrect. In autoimmune diseases, the immune system is overactive, producing antibodies that target the body's own cells, not that it can't create antibodies.
D. "You have developed an infection that is destroying your immune cells."
This statement is incorrect. Infections don't typically destroy immune cells; instead, infections often stimulate the immune system to respond and fight against invading pathogens.
Correct Answer is C
Explanation
A. Gentamicin: Gentamicin is an aminoglycoside antibiotic effective against many bacteria, but it's not the first choice for MRSA. Vancomycin or other alternatives are preferred due to the rising resistance of MRSA to gentamicin.
B. Nafcillin: Nafcillin is a penicillin antibiotic, often used for penicillin-sensitive staphylococcal infections. However, it is not effective against MRSA, which is resistant to many penicillin-based antibiotics.
C. Vancomycin: Vancomycin is a glycopeptide antibiotic used to treat a variety of bacterial infections, including MRSA. It works by inhibiting cell wall synthesis in bacteria, making it effective against Gram-positive bacteria that have developed resistance to other antibiotics like methicillin (which MRSA has).
D. Penicillin: Penicillin is a group of antibiotics that includes drugs like amoxicillin and ampicillin. MRSA is resistant to penicillin-based antibiotics, so they are not effective against MRSA infections.
