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 ["220.6 "]
Explanation
Here's the breakdown of the calculation:
Calculate the concentration of the medication after adding diluent:
Concentration = (Amount of medication) / (Total volume)
Concentration = (1 gm) / (3.4 mL)
Concentration = 0.294 mg/mL
Determine the desired amount of medication per dose:
Desired amount = 750 mg
Calculate the volume of the prepared solution needed to deliver the desired amount of medication:
Volume = (Desired amount) / (Concentration)
Volume = (750 mg) / (0.294 mg/mL)
Volume = 2551.36 mL ≈ 220.6 mL (rounded to one decimal place)
Therefore, you would need to administer approximately 220.6 mL of the prepared solution per dose to deliver 750mg of cefotaxime.
Correct Answer is C
Explanation
Choice A rationale
Theca-lutein cysts are not commonly found in females of reproductive age. They are often associated with conditions that cause high levels of human chorionic gonadotropin, such as molar pregnancies.
Choice B rationale
Corpus luteum cysts can occur in women of reproductive age, but they do not typically regress with the menstrual cycle. Instead, they usually resolve after a few weeks if pregnancy does not occur.
Choice C rationale
Follicular cysts are commonly found in females of reproductive age and often regress with the menstrual cycle. They form when the follicle that normally releases an egg does not open to release the egg.
Choice D rationale
Polycystic ovarian syndrome is a condition characterized by multiple small cysts in the ovaries, but it does not typically cause cysts that regress with the menstrual cycle.
