Final answer:
A CNA should wipe a patient's perineum from front to back to prevent the spread of bacteria and reduce the risk of infection (option 3).
Step-by-step explanation:
When cleaning a patient's Perineum, a CNA should be careful to wipe the resident from front to back. This technique is critical in preventing the spread of bacteria from the anorectal Region to the urethra, which can cause infections such as urinary tract infections.
Unlike wiping in a circular motion from back to front, which is incorrect, or applying significant force, which can cause injury and irritation, the front-to-back method is recommended to maintain optimal hygiene and safety for the patient.
Hence, the answer is option 3.
