Hypertonia, tachycardia, and metabolic alkalosis are not associated with necrotizing enterocolitis (NEC). NEC is characterized by gastrointestinal symptoms and signs of systemic illness.

Choice B rationale

Hypertension, apnea, and ruddy skin color are not specific indicators of necrotizing enterocolitis (NEC). NEC primarily presents with gastrointestinal symptoms and systemic instability.

Choice C rationale

Abdominal distention, temperature instability, and bloody stools are classic signs of necrotizing enterocolitis (NEC). These symptoms indicate severe inflammation and potential bowel necrosis.

Choice D rationale

Scaphoid abdomen, no residual with feedings, and increased urinary output are not characteristic of necrotizing enterocolitis (NEC). NEC typically presents with abdominal distention and feeding intolerance. .

Correct Answer is C

Explanation

Choice A rationale

Oral contraceptive pills, while effective when taken correctly, rely on user compliance and are not the most reliable if doses are missed.

Choice B rationale

Diaphragms with spermicide are less effective than IUDs and require proper placement before intercourse, making them more prone to user error.

Choice C rationale

Intrauterine devices (IUDs) are long-term, highly effective contraceptive methods with low failure rates, and they do not depend on daily user compliance.

Choice D rationale

Male condoms are effective but have a higher failure rate compared to IUDs due to potential breakage or improper use.

A. Oxytocin. B. Progesterone. C. Hindmilk. D. Foremilk.

Correct Answer is A

Explanation

Choice A rationale: Oxytocin is the hormone responsible for the let-down reflex during breastfeeding. It is released from the posterior pituitary gland in response to the baby’s suckling. This hormone causes the milk ducts to contract and eject milk from the alveoli into the ducts, making it available for the baby.

Choice B rationale: Progesterone plays a role in preparing the breast tissue for lactation during pregnancy, but it does not directly trigger the let-down reflex.

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 cause the let-down reflex.

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 cause the let-down reflex.
