1. It is impossible to obtain a midstream urine sample from an infant because an in-fant's neurological system is immature. The best the nurse can do is to apply sterile plastic collection bag to the perineum for urine collection.
2. Holding the infant over a sterile basin cannot overcome the immature neurological system of an infant.
3. Urine wrung out of a diaper is most likely to be grossly contaminated; so, it is use-less.
4. Catheterization is too risky for an infant to obtain a sterile urine specimen unless the infant is already catheterized and aspiration is performed.
