Final answer:
To prevent the spread of Tuberculosis when transporting a patient with a positive TB skin test and respiratory distress, healthcare providers should apply a surgical mask on the patient, wear a HEPA respirator themselves, and maintain suitable distance.
Step-by-step explanation:
When transporting a patient with respiratory distress who has possible Tuberculosis (TB), it's critical to follow proper infection control protocols to prevent the spread of the disease. Given that TB is an airborne pathogen that is spread through coughing, sneezing, and spitting, the most appropriate measure would be option B) Remain at least 3 feet away from the patient and apply a surgical mask on him. This minimizes the risk of transmission. Additionally, as the healthcare provider, you should wear a High-Efficiency Particulate Air (HEPA) respirator to protect yourself from inhaling TB bacteria. The HEPA respirator is necessary due to its ability to filter out very small particles, which can carry the TB bacteria. Remember to also follow standard precautions and use hand hygiene before and after patient contact.
