For diagnostic and treatment purposes, nurses should know birth weight classifications of high risk infants. For example, extremely low birth weight (ELBW) is the designation for an infant whose weight is:
1. less than 1500 g.
2. less than 1000 g.
3. less than 2000 g.
4. dependent on the gestational age.

1. Incorrect. This is the designation for very low birth weight (VLBW); ELBW is less than 1000 g.
2. Correct. An ELBW infant has a birth weight of less than 1000 g.
3. Incorrect. This weight is less than low but too high for extremely low, which is less than 1000 g.
4. Incorrect. Gestational age is a factor with weight in the condition of the preterm birth, but it is not part of the birth weight categorization.
