Which of the following hormones is responsible for stimulating uterine contractions during labor?
- A. Progesterone
- B. Estrogen
- C. Prolactin
- D. Oxytocin
Correct Answer: D
Rationale: Oxytocin is the correct answer as it is the hormone responsible for stimulating uterine contractions during labor. Oxytocin is produced by the pituitary gland and plays a crucial role in initiating and sustaining labor contractions. It acts on the smooth muscle cells of the uterus, causing them to contract and aiding in the progression of labor. Progesterone and estrogen are involved in preparing the uterus for pregnancy but do not directly stimulate contractions. Prolactin is responsible for milk production, not uterine contractions. Therefore, D is the correct answer due to its specific role in labor contractions.

Complete the following sentence by using the list of options. Based on the client findings, the nurse should first admister-----------------and then prepare to administer-----------------------
- A. calcium gluconate
- B. hydralazine
- C. nifedipine
Correct Answer: B,A
Rationale: Rationale:
First administer hydralazine ✅
The client is experiencing severe hypertension (BP 170/112 mm Hg at 1400), which indicates preeclampsia with severe features.
Hydralazine is a fast-acting antihypertensive that helps lower blood pressure and reduce the risk of stroke, placental abruption, or fetal compromise.
Then prepare to administer calcium gluconate ✅
If the client is receiving magnesium sulfate for seizure prevention (common in severe preeclampsia), calcium gluconate is the antidote in case of magnesium toxicity (which can cause respiratory depression or cardiac arrest).
The nurse should have calcium gluconate readily available in case of toxicity signs like loss of deep tendon reflexes, respiratory depression, or cardiac arrhythmias.
Notify the provider 🚨
The severely elevated BP (170/112 mm Hg) and potential risk for eclampsia (seizures) require immediate provider notification for further management.
Which hormone is responsible for stimulating milk production in the breasts?

- C. Prolactin
- D. Oxytocin
Correct Answer: C
Rationale: The correct answer is C: Prolactin. Prolactin is the hormone responsible for stimulating milk production in the breasts. It is produced by the pituitary gland and plays a crucial role in lactation. Progesterone and estrogen are involved in preparing the breasts for milk production but do not directly stimulate it. Oxytocin is responsible for the ejection of milk from the breast but not for its production.
