A nurse is planning care for a client who is to receive a competitive neuromuscular blocking agent. Which of the following items should the nurse plan to have at the client's bedside?

A. Urinary catheter insertion tray: While urinary catheterization may be necessary for some clients, it is not directly related to the use of neuromuscular blocking agents, which primarily affect respiratory function. B. Central venous catheterization tray: A central venous catheterization tray is not necessary for the administration of a competitive neuromuscular blocking agent unless there is a specific need for central venous access, which is not standard for these medications. C. Bag-valve-mask device: Competitive neuromuscular blocking agents cause paralysis, including paralysis of the respiratory muscles. A bag-valve-mask device is essential to provide respiratory support in case the client is unable to breathe on their own after administration of the agent. D. Temporary pacemaker: A temporary pacemaker is not typically needed for clients receiving neuromuscular blocking agents, unless there is a specific indication for pacing, such as arrhythmias, which is not a common complication of neuromuscular blockade.
