Hypersensitivity responses result in:
Autoimmune diseases
Degranulation
Allergic diseases
Deficiency syndromes
The Correct Answer is C
A. Autoimmune diseases involve inappropriate immune responses but are not classified solely as hypersensitivity reactions.
B. Degranulation refers to the release of substances from immune cells, often a part of hypersensitivity reactions, but does not encapsulate the full scope of their consequences.
C. Allergic diseases are directly caused by hypersensitivity responses, which occur when the immune system reacts excessively to harmless substances.
D. Deficiency syndromes relate to a lack of immune function or components, not the excessive responses seen in hypersensitivity reactions.

Correct Answer is A
Explanation
A. A nosocomial infection is one that is acquired in a healthcare setting, such as a hospital. Given that Mary Jones had a Foley catheter inserted on the day of admission and developed symptoms of infection shortly thereafter, this indicates that the infection is likely related to her hospital stay.
B. Community-acquired infections occur outside of healthcare settings, so this does not apply since the infection arose after her hospital admission.
C. While the patient has an acute infection, the classification is more specifically defined by its origin (nosocomial in this case).
D. Since the patient is showing signs of infection (fever and high WBC), it is incorrect to say there is no infection.
Correct Answer is B
Explanation
A. The anterior and posterior trunk account for 36% total (18% each), and both arms (9% each) account for an additional 18%, totaling 54%.
B. The calculation for the burn surface area would be 36% (trunk) + 18% (both arms) = 54%, which is correct.
C. 63% is too high based on the rule of nines calculations.
D. 44% underestimates the total burn surface area considering both trunk and arms.
