Final answer:
The nurse should explain to the husband the necessity of hearing the patient's responses directly to assess awareness and orientation for accurate and safe care. The nurse might need to interview the patient in private.
Step-by-step explanation:
The best action for the nurse when a patient's husband interrupts and answers questions during an admission assessment is to politely explain the importance of hearing the patient's own responses. The nurse can emphasize that understanding how the patient communicates is crucial for providing personalized care and ensuring patient safety. This is because asking a patient to state their name or respond to questions is a method to evaluate if the patient is aware, oriented, and capable of interacting. The nurse may need to conduct the interview with the patient privately, if appropriate, to ensure that the patient feels comfortable to speak freely without the influence or interference from the patient's husband.
