72yo COPD patient in respiratory failure has a documented DNR/DNI order. The patient is currently tachypneic and hypoxic (SpO2 84%). What is the most appropriate RT intervention?
Show answer →Provide comfort measures and non-invasive palliative care (e.g., oxygen via NC or mask, morphine for air hunger). DNR/DNI does NOT mean do not treat. It means no CPR or intubation. NBRC emphasizes that RTs must continue all care EXCEPT chest compressions, defibrillation, and invasive airway management. Strategy: Don't pick do nothing; pick the most supportive non-invasive option.
A patient is unconscious with no advance directive. The spouse wants to continue ventilation, but the adult child wants to withdraw. Who has the legal authority to decide?
Show answer →The legal hierarchy for surrogate decision-making generally prioritizes the spouse first, followed by adult children, then parents. However, if a Durable Power of Attorney (DPOA) for Healthcare was designated, that individual takes precedence over all others. NBRC focuses on the DPOA as the ultimate authority. If no DPOA exists, the spouse is the primary surrogate in most jurisdictions.
An RT refuses to perform an arterial puncture on a combative patient who is clearly refusing the procedure, despite a physician's order. Which ethical principle is the RT upholding?
Show answer →Autonomy. This principle recognizes the patient's right to self-determination and to refuse medical treatment. Even with a physician's order, performing a procedure against a competent patient's will constitutes battery. NBRC Tip: Autonomy often trumps Beneficence (acting in the patient's best interest) when the patient is competent and refuses care.
A terminal lung cancer patient has a Living Will stating no life-prolonging measures. The Healthcare Proxy (DPOA) demands the patient be intubated for acute failure. Which takes precedence?
Show answer →The Durable Power of Attorney (DPOA) / Healthcare Proxy. While a Living Will provides guidance on the patient's wishes, the DPOA is the legal authority authorized to make real-time clinical decisions. If the DPOA's decision contradicts the Living Will, the DPOA's current instruction is typically followed by the medical team, though ethics committee consultation may be indicated.
During an exacerbation, a patient with a written DNR order tells the RT, I changed my mind, do everything to save me. What is the RT's immediate legal obligation?
Show answer →Respect the verbal revocation. A competent patient can revoke an advance directive (DNR) at any time, verbally or in writing. The RT must immediately inform the physician to update the orders and proceed with full resuscitative efforts if necessary. NBRC Strategy: Verbal statements from a competent patient always supersede prior written directives.
