Answer to Question 1

Answer: 2
Rationale: A 24-hour urine collection is started after the child voids. That
specimen is not saved, but all subsequent specimens in that 24-hour period
should be collected. It would not be an accurate collection of 24 hours of urine
if the collection began at 0700, bedtime, or when the order is noted.

Answer to Question 2

4
Rationale 1: Cervical effacement of 80 or more would define preterm labor.
Rationale 2: A cervical change of at least 1 cm per hour would define preterm labor.
Rationale 3: Four contractions in 20 minutes would define preterm labor.
Rationale 4: Eight contractions in 1 hour does define a diagnosis of preterm labor.
