Final answer:
a. Suction machine
A nurse should prepare a suction machine for a client with dysphagia to quickly clear the airway in case of aspiration or choking; wire cutters and padded clamps are not related to dysphagia care, and though a communication board is helpful, it does not address emergency needs.
Step-by-step explanation:
A nurse preparing to admit a client with dysphagia, which is difficulty in swallowing, should plan to place a suction machine at the client's bedside. Dysphagia can lead to an increased risk of aspiration or choking, and the suction machine is essential for quickly clearing the airway if necessary. In contrast, wire cutters and padded clamps are not typically associated with the care of a client with dysphagia, as they are more suited for situations involving casts or metal pins. Moreover, while a communication board may be helpful for patients who have difficulty speaking due to their condition or concurrent treatments, it does not address the immediate risk of aspiration. Therefore, safety and the ability to respond to potential emergencies are the primary reasons for having a suction machine readily available.
