What type of wound healing occurs when wound surfaces can be brought together and held in place?
Primary intention
Quarternary intention
Tertiary intention
Secondary intention
The Correct Answer is A
Rationale:
A. Primary intention healing occurs when wound edges are clean, closely approximated, and can be held together with sutures, staples, or adhesive. This type of healing is typical for surgical incisions or clean lacerations. Healing is usually fast, with minimal scarring, because tissue loss is minimal and infection risk is low.
B. Quarternary intention is not a recognized classification in wound healing. This option is incorrect.
C. Tertiary intention, also called delayed primary closure, occurs when a wound is initially left open to allow for drainage or infection control and is later closed surgically. This method is used for contaminated or infected wounds, not clean wounds that can be approximated immediately.
D. Secondary intention occurs when wounds cannot be approximated, often due to significant tissue loss, infection, or pressure ulcers. Healing occurs from the base upward, filling in with granulation tissue over time. This process is slower, results in larger scars, and carries a higher risk of infection compared to primary intention.

Correct Answer is ["A","B","D","E"]
Explanation
Rationale:
A. Incontinence exposes skin to moisture, friction, and chemical irritation, increasing the risk for skin breakdown and pressure injuries. Constant moisture softens the skin (maceration), making it more susceptible to damage from pressure or shear.
B. Loss of sensation, such as in spinal cord injury, prevents the individual from feeling discomfort or pain that signals the need to shift position. Without this feedback, prolonged pressure on bony prominences can lead to tissue ischemia and ulcer formation.
C. An individual with full mobility and intact sensation can reposition themselves and relieve pressure, which significantly reduces risk of pressure ulcer development.
D. Malnutrition impairs skin integrity and wound healing. Deficiencies in protein, vitamin C, zinc, and calories reduce tissue repair capacity, making the skin more prone to breakdown under pressure.
E. Individuals who cannot reposition themselves independently rely on caregivers for movement. If repositioning is infrequent or delayed, pressure remains on bony prominences, increasing risk for ulcers.
Correct Answer is B
Explanation
Rationale:
A. Seasonal allergic rhinitis is a type I hypersensitivity reaction, which is IgE-mediated. It occurs when allergens trigger histamine release from mast cells, causing sneezing, itching, and nasal congestion.
B. Systemic lupus erythematosus (SLE) is a type III hypersensitivity reaction, characterized by the formation of immune complexes (antigen-antibody complexes) that deposit in tissues such as the kidneys, joints, skin, and blood vessels. These complexes trigger inflammation and tissue damage through complement activation and recruitment of inflammatory cells. Common manifestations include arthritis, nephritis, rashes, and vasculitis.
C. Poison ivy causes a type IV hypersensitivity reaction, also called a delayed-type hypersensitivity, which is cell-mediated rather than antibody-mediated. The reaction occurs 24–72 hours after exposure and involves T lymphocytes responding to the allergen.
D. Acute hemolytic blood transfusion reactions are type II hypersensitivity reactions, which are antibody-mediated cytotoxic reactions. Preformed antibodies bind to donor red blood cells, leading to cell lysis and hemolysis.
