A patient has severe allergic reactions to grass, mold, and dust. He is scheduled for a skin test to determine his sensitivity. He states he has been taking corticosteroids to help control his symptoms
What nursing intervention should the nurse implement?
A) The patient should take his corticosteroids regularly prior to testing.
B) The nurse should only test for grass, mold, and dust initially.
C) The nurse should have an emergency kit available in case of anaphylaxis.
D) The nurse should cancel the test until he is off the corticosteroids.
Ans: D
Feedback: False negative results may occur because of improper technique, outdated allergen solutions, and prior use of medications that suppress skin activity. Corticosteroids and antihistamines, including allergy medications, suppress skin test reactivity and are usually withheld 48 to 96 hours before testing. The patient should be tested for all possible allergens. When testing is performed, the emergency kit should be available. The most important nursing intervention is to cancel the test until he is off the corticosteroids for 48 to 96 hours.
