For which reason would a nurse in the well-baby nursery report to the neonatologist that a newborn appears to be preterm?
The baby has a square window angle of 90 degrees.
The baby has leathery and cracked skin.
The baby has a popliteal angle of 90 degrees.
The baby has pronounced plantar creases.
The Correct Answer is A
Choice A is correct. The square window angle, formed by the intersection of the ear and the jawline, is an important physical assessment finding in neonates. In full-term babies, this angle is typically greater than 90 degrees, appearing more rounded. However, in preterm babies, the angle is often closer to 90 degrees, appearing more square due to underdeveloped facial features and subcutaneous tissue.
Choice B is incorrect. While leathery and cracked skin can be present in both term and preterm babies, it's not a specific indicator of prematurity alone. It can be caused by various factors like intrauterine growth restriction, dehydration, or underlying skin conditions.
Choice C is incorrect. The popliteal angle, formed by flexing the knee and measuring the angle between the thigh and lower leg, is not a reliable indicator of prematurity. It can vary even among term babies and is influenced by other factors like muscle tone and positioning.
Choice D is incorrect. Pronounced plantar creases, the lines on the soles of the feet, are also not specific to prematurity. While they may be deeper in some preterm babies, they can also be present in full-term infants and their depth can vary greatly between individuals.

Correct Answer is ["B","C","D"]
Explanation
Choice A rationale
Breastfeeding every 2 hours is actually recommended for newborns and is not a contributing factor to mastitis.
Choice B rationale
Substituting breastfeeding sessions with formula feeding can contribute to mastitis. This is because the milk that is not removed from the breast can lead to engorgement and blocked ducts, which can result in infection.
Choice C rationale
Blisters and cracks on the nipples can allow bacteria to enter the breast tissue, leading to infection and mastitis.
Choice D rationale
Alternating breastfeeding positions can help ensure that the breasts are emptied completely during each feeding, which can help prevent mastitis.
Correct Answer is D
Explanation
Choice A rationale
A Pap smear is not helpful in identifying ovarian cancer. It is used to detect cervical cancer, not ovarian cancer.
Choice B rationale
While the CA-125 blood test can indicate the presence of ovarian cancer if the levels are elevated, it is not a reliable screening test. This is because high levels of CA-125 can also be caused by common conditions such as endometriosis and pelvic inflammatory disease.
Choice C rationale
Genetic testing for two genes (BRCA1 and BRCA2) can identify an increased risk for developing ovarian cancer, but it does not diagnose the disease itself.
Choice D rationale
Currently, there is no reliable screening test for ovarian cancer. The most effective strategies for early detection are being aware of the symptoms and maintaining regular check-ups with your healthcare provider.
