A nurse is setting up the equipment to assist with a sigmoidoscopy while the practical nurse (PN) positions the client in a flat prone position. Which action should the nurse implement?

Choice A reason: Assuming care of the client and reassigning the PN does not address the immediate need to correct the client's position for the sigmoidoscopy. Choice B reason: While assistance may be needed, it is more important to first ensure that the client is in the correct position for the procedure. Choice C reason: Acknowledging the PN's action would be incorrect since the client has not been positioned safely and correctly for a sigmoidoscopy. Choice D reason: Demonstrating the correct positioning ensures the procedure can be performed effectively and safely, which is the nurse's immediate responsibility.
