Which instruction is appropriate for a client during the insertion of an indwelling catheter?

During the insertion of an indwelling catheter, instructing the client to "bear down" is appropriate as it helps facilitate the proper placement of the catheter. Bearing down can assist in relaxing the sphincters and the urethra, making it easier for the catheter to pass through the urethra and into the bladder. This technique mimics the action of having a bowel movement, which can help relieve any tension that may be present, thus aiding in the smooth insertion of the catheter.

While there are various techniques and instructions that could be provided during this procedure, guiding the client to bear down directly relates to the physiological response needed for successful catheterization. Other instructions, such as relaxing the abdominal muscles or inhaling deeply, may be supportive but do not have the same direct impact on the insertion process as instructing the client to bear down.
