Step-by-step explanation:
The action that would be inappropriate for the nurse to perform is c) Making unilateral decisions without considering clients' preferences and input. Nursing care, especially under the direct supervision of a registered nurse, should always involve patient-centered communication and shared decision-making. The nurse should collaborate with other healthcare professionals and the client to review and update care plans, and actively engage in monitoring clients' responses to interventions to ensure care is accurate and responsive to changes in the clients' conditions. Unilateral decision-making could undermine the trust and therapeutic relationship between the nurse and the patient and may lead to negative health outcomes.
