Final answer:
The nurse should use the Electronic Health Record (EHR) to manage and communicate about a client's adverse reaction to medication, as it ensures confidentiality and professional communication within the healthcare team.
Step-by-step explanation:
A nurse caring for a client experiencing adverse effects after a new medication should use the Electronic Health Record (EHR) to document the incident and communicate with the healthcare team. The EHR allows for quick and accurate sharing of patient information among healthcare providers, ensuring a coordinated response to the complication. The other options listed, such as social media platforms, written letters, and Morse code, are not appropriate for professional and confidential communication regarding patient care.
In addition to documenting the adverse effects in the EHR, the nurse should inform the healthcare team promptly. This often includes discussing the situation with the surgeon, nurse, and anesthesia professional to review aloud key concerns for the patient's recovery and care. This approach facilitates a comprehensive understanding of the patient's current condition and enables the team to adjust the treatment plan as necessary.
