An adult patient has a Mantoux test result of 10.5 mm for tuberculosis. What is the most appropriate action for the nurse practitioner regarding the patient's healthcare?

The most appropriate action regarding the patient’s healthcare, given a Mantoux test result of 10.5 mm, is oriented around the ethical obligation to provide care. In this context, the responsibility of the nurse practitioner extends to ensuring that the patient's health needs are met, which includes assessing for possible tuberculosis (TB) exposure and managing it appropriately.

A tuberculin skin test result of 10.5 mm is considered positive in individuals with certain risk factors or in populations with a higher prevalence of TB. Therefore, the nurse practitioner should initiate further assessment or management for this patient based on established guidelines for TB screening and treatment, without any barriers related to the patient's legal status.

The focus here is on patient care and management, emphasizing that healthcare professionals have an ethical duty to provide care, including preventative measures and follow-up for communicable diseases like TB. This duty includes not discriminating against patients based on their immigration status, thereby upholding the principle of providing equitable healthcare services.

In this way, the correct response aligns with the commitment of healthcare providers to prioritize patient welfare and adhere to ethical standards in practice, thereby ensuring that the individual receives the necessary follow-up for their positive TB test.
