Procedures and Pharmacology
chest x-ray (CXR): Radiological picture of the lungs. Mantoux test: Intradermal injection of tuberculin purified protein derivative (PPD) just beneath the surface of the skin to identify whether the patient has been exposed to tuberculosis. metered dose inhaler (MDI): Handheld device used to deliver medication to the patient’s lower airways. A metered dose inhaler with a spacer, or extender, allows the patient to avoid having to synchronize inhalation with the medication’s release from the inhaler (Figure 8-5). nebulizer: Device that produces a fine spray or mist to passively deliver medi- cation to a patient’s deep airways (Figure 8-6).
