The hormone responsible for the production of breast milk is:
Prolactin.
Progesterone.
Hindmilk.
Foremilk.
The Correct Answer is A
Choice A rationale: Prolactin is the hormone responsible for the production of breast milk. It is produced by the anterior pituitary gland and stimulates the mammary glands to produce milk. Prolactin levels increase during pregnancy and breastfeeding to ensure a sufficient milk supply.
Choice B rationale: Progesterone plays a role in preparing the breast tissue for lactation during pregnancy, but it does not directly stimulate milk production.
Choice C rationale: Hindmilk is the milk produced later in a feeding session, which is richer in fat and calories. It is not a hormone and does not stimulate milk production.
Choice D rationale: Foremilk is the initial milk released during breastfeeding, which is higher in water content. It is also not a hormone and does not stimulate milk production.

Correct Answer is C
Explanation
Choice A rationale
A diaphragm must be left in place for at least 6 hours after intercourse to prevent sperm from reaching the uterus. This ensures effective contraception.
Choice B rationale
Depo-Provera is a long-acting contraceptive injection, and fertility can return within a few months after stopping, but it may take up to 9-10 months for some women to regain their regular menstrual cycles and fertility.
Choice C rationale
The Ortho Evra patch is a hormonal contraceptive that is applied weekly, not monthly. It needs to be replaced once a week for three weeks, followed by a patch-free week.
Choice D rationale
Male and female condoms should not be used together because they can create friction and cause either or both condoms to break or slip, reducing their effectiveness as contraceptives and increasing the risk of sexually transmitted infections.
Correct Answer is B
Explanation
Choice A rationale
Keeping the baby's bassinet away from fans is good practice to avoid drafts that could make the baby cold. Maintaining a stable environment is important for newborns to help regulate their body temperature effectively.
Choice B rationale
Checking the baby's temperature rectally every 3 hours is unnecessary and potentially harmful. Rectal temperature checks are invasive and not typically needed unless directed by a healthcare provider. Axillary temperature is safer and more commonly recommended.
Choice C rationale
Keeping the baby's head covered can help maintain body temperature, especially in cooler environments. Newborns can lose heat quickly through their heads, so this practice is beneficial to keep them warm.
Choice D rationale
Placing the baby on the stomach and covering with a warm blanket is not recommended for sleeping due to the risk of sudden infant death syndrome (SIDS). Babies should be placed on their backs to sleep to reduce this risk. .
