Why must clients who will undergo diagnostic skin test avoid taking antihistamine or cold preparations for at least 48-72 hrs before testing?

  • A. Antihistamines may increase the potential for excessive bleeding
  • B. Antihistamines may aggravate the allergic reaction
  • C. Antihistamines may increase the potential for false negative results
  • D. Antihistamines may cause wheezing
Correct Answer: C

Rationale: Antihistamines are medications commonly used to relieve symptoms of allergies, including itching, sneezing, and hives. When a client undergoing a diagnostic skin test for allergies takes antihistamines, it can suppress the body's allergic response, leading to false negative results. This means that the test may not accurately identify all the substances to which the client is allergic, potentially leading to a misdiagnosis. To ensure the accuracy of the skin test, clients are advised to avoid taking antihistamines or cold preparations for at least 48-72 hours before the testing to allow their body to exhibit the appropriate allergic response.
