Final answer:
To prepare for catheterization, step 2 is to clean the genital area with an antiseptic solution, aiming to reduce the risk of infection before catheter insertion. This step is critical due to the proximity of the urethra to sources of bacteria and the varying anatomical features between males and females.
Step-by-step explanation:
The initiation of treatment and preparation for catheterization involves several steps to ensure the procedure is done safely and effectively. Among the choices given, the correct answer for step 2 is to clean the genital area with an antiseptic solution. Before inserting the catheter into the urethra, it's essential to minimize the risk of infection by cleaning the area where the external urethral orifice is located. This orifice is particularly prone to infections in females due to the shorter length of the urethra, measuring approximately 4 cm. The female urethra is also in close proximity to potential sources of bacteria, such as fecal matter. For males, the urethra is longer, averaging 20 cm and, while also requiring antiseptic cleaning, presents a different anatomical challenge.
To cater to these anatomical differences and reduce the likelihood of urinary tract infections (UTIs), especially in females, the external genitalia must be carefully cleaned. This preparatory step is crucial before proceeding to step 3, where sterile gloves are applied and followed by the insertion of the catheter into the urethra.
