Final answer:
Oral hygiene for a patient with an Endotracheal Tube (ETT) should be provided every two to four hours with proper tools and antiseptic solution to prevent infection and maintain oral health.
Step-by-step explanation:
Providing oral hygiene for someone with an Endotracheal Tube (ETT) is an important part of patient care. It is generally recommended that oral care should be provided at least every two to four hours to prevent infection, such as ventilator-associated pneumonia, and to ensure the patient's comfort and oral health. It's important to use a soft toothbrush or foam swabs and an antiseptic solution when performing oral care, and suction may be required to clear any secretions.
