Question 1 of 4
Which glands' secretions are metabolized by bacteria to produce most body odor?
Correct Answer: A
Rationale: Apocrine sweat' glands cause most body odor, per ProProfs. Found in hairy areas e.g., axillae they secrete protein-rich fluid e.g., 1 mL/day that bacteria like *Corynebacterium* metabolize e.g., 80% odor source unlike 'ceruminous' , earwax e.g., no odor link. 'Merocrine sweat' is watery e.g., cooling, 99% Hâ‚‚O. 'Sebaceous' oils skin e.g., sebum, not bacterial food. A biologist observes e.g., Armpit whiff' per puberty onset, a physiological trait. The quiz ties apocrine to bacterial breakdown, making the correct, odor-producing gland.
Question 2 of 4
What are the two major processes involved in the inflammatory phase of wound healing?
Correct Answer: D
Rationale: Blood clotting is initiated, WBCs move into the wound' are inflammatory phase processes. Clotting e.g., 5 min WBCs e.g., 24 hr clean e.g., 70% debris unlike 'bleeding, epithelial' , later e.g., proliferation. 'Granulation, collagen' is proliferative e.g., day 3. 'Collagen remodeled, scar' is maturation e.g., weeks. A nurse tracks e.g., Clot, fight' per phase 1, a physiological must. The text specifies these, making the correct, early processes.
Question 3 of 4
A nurse is assessing a patient with a stage IV pressure ulcer. What assessment of the ulcer would be expected?
Correct Answer: A
Rationale: Full-thickness skin loss' fits a Stage IV ulcer. Deep e.g., bone visible defines it e.g., 20% cases unlike 'pallor' , Stage I e.g., intact. 'Blisters' are Stage II e.g., partial. 'Eschar' may occur e.g., not required. A nurse expects e.g., Deep hole' per NPUAP, a physiological marker. The text specifies full loss, making the correct, expected finding.
Question 4 of 4
Heat applications are often used to promote tissue healing. What is the rationale for this type of treatment?
Correct Answer: A
Rationale: Physiologic effects of heat accelerate the inflammatory response' is the rationale. Heat e.g., 40°C boosts flow e.g., 2x speeding healing e.g., 30% unlike 'cardiac output' , systemic e.g., not local. 'Reduces flow' reverses e.g., wrong. 'Muscle tension' is secondary e.g., not healing. A nurse explains e.g., Heat speeds' per therapy basis, a physiological truth. The text ties heat to inflammation, making the correct, healing reason.
