Answer: A - The nurse should avoid vigorous urethral cleaning as it allows the movement of the catheter in all directions, increasing the risk of infection. Increasing oral fluid intake dilutes the urine, prevents stone formation, and washes away microorganisms that may have accumulated in the bladder. It also helps in keeping the urine acidic. Anchoring the catheter securely on the thigh or abdomen ensures that no further trauma to the urethral lining is done. Silicone-made catheters have lesser chances of encrustation.
