2. The nurse observes a small bubble just under the skin's surface on needle with-drawal after a properly administered tuberculin skin test; an intradermal injection deposits medication below the skin but above subcutaneous tissue. The wheal is practically clear, denoting that the medication is in an avascular area.
1. The pocket of test solution is relatively soft and superficial.
3. Blood should not trickle from the injection site; if it does, the injection is poten-tially too deep.
4. Within 1 hour, most intradermal tests are completely absorbed unless the client has a reaction to the fluid, as with allergy testing or a positive tuberculin skin test.
