The nurse is working with a colleague who has a delayed hypersensitivity (type IV) allergic reaction to latex. Which statement describes the clinical manifestations of this reaction?
Symptoms are localized to the area of exposure, usually the back of the hands.
Clinical manifestations of a delayed hypersensitivity reaction are localized to the area of exposure. Clinical manifestations of an irritant contact dermatitis can be eliminated by changing glove brands or using powder-free gloves. With an irritant contact dermatitis, avoid use of hand lotion before donning gloves; this may worsen symptoms, as lotions may leach latex proteins from the gloves. When clinical manifestations occur within minutes after exposure to latex, which is described as a latex allergy, an immediate hypersensitivity (type I) allergic reaction has occurred.
