Question

When giving a (PPD) purified protein derivative injection or TB test, the CMA should draw up _______of vaccine into the syringe.

Answer 1

The CMA should draw up 0.1 ml of the Tuberculin solution when administering a PPD injection to test for tuberculosis exposure.

Step-by-step explanation:

When administering a Purified Protein Derivative (PPD) injection, also known as the TB test or Mantoux test, the Certified Medical Assistant (CMA) should draw up 0.1 ml of the Tuberculin solution into the syringe.

This amount is specifically designed to test for tuberculosis (TB) exposure by creating a small, raised wheal on the skin of the forearm. After the injection, the site should be checked for a reaction, typically 48 to 72 hours later, to assess if there has been an immune response indicative of TB exposure.

For the PPD injection or TB test, a small amount of tuberculin protein derivative is injected into the skin. The recommended amount for this injection is 0.1 mL. It is important to accurately measure and administer the correct dosage to ensure accurate test results and avoid any potential complications.
