You're a medical assistant in a pediatric clinic and need to collect a urine sample from a non-toilet-trained toddler for routine urinalysis. Which method is appropriate to use for collecting the urine sample?
Place cotton balls inside the diaper and squeeze the urine into a container after the child has voided.
Ask the toddler to urinate into a sterile specimen container.
Insert a sterile catheter into the bladder to collect the sample.
Apply a pediatric urine collection bag to the genital area and wait for the child to void.
