A nurse is teaching ethical decision-making to a group of newly licensed nurses. Which of the following actions should the nurse identify as the first step in ethical behavior?

Rationale:

A. Position the client to maintain hip flexion: Hip flexion greater than 90 degrees increases intra-abdominal and intrathoracic pressure, which can impair venous return from the brain and raise intracranial pressure. The hips should be kept in a neutral, extended position.

B. Administer an enema if the client develops constipation: While managing constipation is important, enemas can stimulate the vagus nerve and raise ICP due to straining. Stool softeners or gentle interventions are preferred to avoid abrupt increases in intracranial pressure.

C. Provide 100% oxygen to the client prior to suctioning: Preoxygenation prevents hypoxia, which can increase cerebral blood flow and elevate ICP. Suctioning should always be preceded by hyperoxygenation to reduce this risk in patients with brain injuries.

D. Ensure that the PEEP level is set at 20 cm of H2O: High PEEP levels like 20 cm H₂O can impede cerebral venous outflow and raise ICP. PEEP should be used cautiously in clients with brain injuries and adjusted to the lowest effective setting to maintain oxygenation.

Rationale:

A. Call the unit supervisor: While the unit supervisor plays a role in the chain of command, the nurse should first address the situation at the unit level with immediate leadership before escalating to higher administration.

B. Notify the medical director: The medical director is a high-level administrator typically involved in policy and oversight rather than immediate clinical decisions. This step would occur further along the chain if lower-level leadership fails to respond.

C. Consult with the charge nurse: The charge nurse is the first point of escalation in the nursing chain of command. They are immediately available, familiar with the unit workflow, and can take prompt action or assist in contacting the provider or other necessary personnel.

D. Notify the department head: The department head oversees broader unit operations and would be consulted if the charge nurse and unit supervisor cannot resolve the situation. However, this is not the most immediate first step in an emergency.
