A patient who is scheduled for a skin test to determine his sensitivity has severe allergic reactions to grass, mold, and dust
The patient tells the nurse 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 cart 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Feedback: False-negative results may occur because of improper technique, outdated allergen solutions, and prior use of medications that suppress skin activity.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. You would not test the patient if he is taking his steroids; you would not test for grass, mold, or dust; and there would be no need for an emergency cart.
