True or false: All newborns should be screened for tuberculosis with a PPD.

The assertion that all newborns should be screened for tuberculosis (TB) with a PPD test is false. Routine screening for TB using a PPD (purified protein derivative) test is not universally recommended for all newborns.

The United States Preventive Services Task Force and the Centers for Disease Control and Prevention suggest that TB screening should be targeted rather than universal. Newborns, especially, are generally not at high risk for tuberculosis unless they have specific risk factors. This includes being born to a parent or caregiver who has active TB, exposure to someone with active TB, or living in an area with a high incidence of the disease.

Screening practices focus on individuals who have risk factors that might increase their susceptibility to infection, rather than screening every newborn indiscriminately. Therefore, the correct answer accurately reflects the current guidelines and understanding of TB screening protocols in the context of well-child care.
