Washing and drying the infant's genitalia and perineum thoroughly is a critical step in the process of collecting a urine specimen using a urine collection bag. This action is essential because it helps to ensure the accuracy of the specimen by minimizing the risk of contamination. Clean genitalia prevent the introduction of bacteria or other substances that could alter the results of the urine analysis, leading to potential misdiagnosis or inappropriate treatment decisions.

A thorough cleansing process removes any debris, skin cells, or contaminants that might otherwise mix with the urine sample, providing a clearer picture of the infant's urinary health. It additionally helps in preventing any irritations or infections that may arise from residual substances on the skin.

The other options do not address the primary concern of obtaining a clean specimen effectively. For instance, applying lubricant may not be necessary and might introduce foreign substances into the sample. Similarly, being cautious about the scrotum is less relevant than ensuring a clean collection site, and waiting several hours before checking the device can lead to unnecessarily delayed collection and increased chances of sample contamination.
