What person is in the prodromal stage of influenza infection?
A person who was previously ill and is now feeling better
A person who has a cough, stuffy nose, and chest pain
A person who was exposed to influenza with no symptoms
A person who has fatigue, soreness, and a headache
The Correct Answer is D
Choice A reason: A person recovering from influenza is in the convalescent stage, not the prodromal stage, which occurs before full symptoms. Recovery indicates resolution of infection, not early nonspecific symptoms, making this choice incorrect.
Choice B reason: Cough, stuffy nose, and chest pain indicate the acute stage of influenza, with full-blown respiratory symptoms. The prodromal stage involves nonspecific symptoms before respiratory manifestations, making this choice incorrect for the prodromal phase.
Choice C reason: A person exposed to influenza with no symptoms is in the incubation period, not the prodromal stage. The prodromal stage involves early, nonspecific symptoms, not asymptomatic infection, making this choice incorrect.
Choice D reason: The prodromal stage of influenza involves early, nonspecific symptoms like fatigue, soreness, and headache before respiratory symptoms develop. These reflect the body’s initial response to viral replication, making this the correct choice for the prodromal stage.

Correct Answer is A
Explanation
Choice A reason: Poison ivy causes a type IV (cell-mediated) hypersensitivity reaction, where T-cells react to urushiol, triggering a delayed inflammatory response. This leads to dermatitis with itching and rash, making this the correct choice.
Choice B reason: Allergic hypersensitivity is a broad term, often referring to type I (IgE-mediated) reactions, like anaphylaxis. Poison ivy involves T-cell-mediated delayed hypersensitivity, not immediate allergic responses, making this choice incorrect.
Choice C reason: Immune complex hypersensitivity (type III) involves antigen-antibody complexes causing tissue damage, as in lupus. Poison ivy reactions are T-cell-driven, not immune complex-mediated, making this choice incorrect for the reaction.
Choice D reason: Cytotoxic hypersensitivity (type II) involves antibodies attacking cell surface antigens, as in hemolytic anemia. Poison ivy causes a T-cell-mediated skin reaction, not antibody-driven cytotoxicity, making this choice incorrect.
Correct Answer is ["A","C","E"]
Explanation
Choice A reason: Stabilizing the wrist with an elastic wrap supports the injured ligaments, reducing movement and further damage. It promotes healing by maintaining alignment, making this a correct action for acute wrist sprain management.
Choice B reason: Applying a warm pack increases blood flow, which may worsen swelling in an acute sprain. Cold therapy is recommended to reduce inflammation and pain, making this choice incorrect for acute sprain management.
Choice C reason: Elevating the wrist above the heart reduces swelling by decreasing hydrostatic pressure, allowing fluid to drain from the injury site. This minimizes edema, making this a correct action for acute wrist sprain.
Choice D reason: Frequent massage may aggravate an acute sprain by increasing inflammation and pain. Rest and immobilization are preferred to promote healing, making this choice incorrect for acute wrist sprain management.
Choice E reason: Resting the wrist prevents further injury to damaged ligaments, allowing healing and reducing inflammation. Avoiding strain is critical in acute sprains, making this a correct action for wrist sprain recovery.
