What are hypertonic contractions?
when uterus never fully relaxes

when uterus relaxes too much and has ineffective contractions

a. 2-7 days
The health care provider has determined that the source of dystocia for a woman is related to the fetus size. The nurse would know that macrosomia would indicate the fetus weighs which of the following? a. 4,000 g or more b. 4,500 g or more c. 3,000 g or more d. 3,500 g or more
a. 4,000 g or more
A woman is to undergo labor induction. The nurse determines that the woman most likely requires cervical ripening if her Bishop score is: a. 5 b. 6 c. 7 d. 8
a. 5 Explanation: A bishop score less than 6 usually indicates that a cervical ripening method should be used before labor induction

a. Caput succedaneum
