down reflex)?

B) Estrogen
C) Prolactin

Rationale: Oxytocin triggers the milk ejection reflex by causing
myoepithelial cells to contract, expelling milk from the alveoli into
the ducts. Prolactin (C) is responsible for milk production, while
progesterone (A) and estrogen (B) play roles in pregnancy but inhibit
lactation postpartum.

postpartum. The most likely cause is:
,A) Oversupply
B) Poor latch
C) Thrush
D) Raynaud's phenomenon (CORRECT ANSWER)

leading to cracking and pain; correcting latch is key. Oversupply (A)
causes engorgement; thrush (C) involves yeast; Raynaud's (D) causes
blanching.
