Latex allergy is an exaggerated immune-mediated reaction when one is exposed to products or dusts containing latex, a natural rubber used in many medical devices (eg, gloves, catheters, tape). Many people, particularly health care workers and individuals requiring chronic invasive procedures (eg, self-catheterization), develop latex allergy from repeated exposures. When assessing for potential latex allergies, the nurse should inquire about the client’s reactions to common latex-containing objects and potentially cross-allergenic products. Balloons commonly contain latex, and reports of lip swelling, itching, or hives after contact indicate a high risk for anaphylactic reactions with continued exposure (Option 5). Many food allergies (eg, avocado, banana, tomato) also increase the risk for latex allergy because the food proteins are similar to those found in latex (Option 3). (Option 1) There is no documented cross-sensitivity reaction between ACE inhibitors (eg, lisinopril) and latex. (Option 2) Epilepsy is not associated with an increased risk for latex allergy. However, clients who have spina bifida or who have undergone multiple surgeries are at increased risk. (Option 4) Shellfish allergy was previously believed to be associated with allergy to iodine (CT contrast material), which has now been disproved. Shellfish allergy has no relationship to latex allergy.
