Which option is considered a line, drain, or airway (LDA) in medical documentation?

In medical documentation, the term "line, drain, or airway (LDA)" refers specifically to devices or interventions that involve direct access to the body for therapeutic or monitoring purposes. A tracheostomy is a surgical procedure that creates an opening in the neck to place a tube into the trachea, allowing for ventilation and airway management. This intervention is essential in various medical scenarios, particularly in cases where normal breathing is compromised.

The other options do not fit into the LDA category. Continuous telemetry is a method of monitoring heart rhythms, but it does not represent a direct line into the body. Body piercing and tattoos are cosmetic modifications and do not serve a medical purpose related to airway maintenance or monitoring. Thus, the tracheostomy is the correct answer as it is a medical procedure that directly involves an airway and is crucial for patient care in certain respiratory conditions.
