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.

Answer and Explanation

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

Explanation

Choice A rationale
A negative pregnancy test is important to rule out pregnancy as a cause of abnormal uterine bleeding (AUB), but it is not the priority finding. Pregnancy is one of the common causes of AUB in reproductive-age women, but the user’s question is about prioritizing findings, and other choices are more critical to assess the patient’s condition.
Choice B rationale
Hemoglobin and hematocrit levels are crucial in assessing the severity of AUB. Chronic heavy or prolonged uterine bleeding may cause iron deficiency anemia. Therefore, these tests are prioritized to determine the patient’s blood volume and to plan appropriate interventions.
Choice C rationale
While an elevated white blood cell count could indicate an infection, which can also cause AUB, it is not the priority in this case. Infections are less common causes of AUB, and the symptoms would likely include pain, fever, or abnormal discharge.
Choice D rationale
Serum cholesterol levels are not directly related to AUB. While it’s important to monitor cholesterol levels for overall health and cardiovascular risk management, it’s not a priority in the assessment of AUB12.

A. I need to wear gloves when doing any gardening. B. Any blood pressures need to be taken in my right arm. C. I should wear clothing with elastic sleeves. D. Blood specimens should be drawn from my right arm.

Correct Answer is C

Explanation

Choice A rationale
Wearing gloves while gardening is a recommended practice after a mastectomy, especially on the side where lymph nodes have been removed. This is to protect the skin and reduce the risk of infection, which could trigger lymphedema.
Choice B rationale
It is indeed recommended that blood pressures be taken in the unaffected arm after a mastectomy. This is because the pressure from the cuff can obstruct lymph flow and potentially trigger lymphedema in the arm where lymph nodes have been removed. Choice C rationale
Wearing clothing with elastic sleeves is not recommended after a mastectomy. Elastic bands can restrict lymph flow and increase the risk of lymphedema.
Choice D rationale
Similar to blood pressure measurements, it is recommended that blood specimens be drawn from the unaffected arm after a mastectomy. This is to avoid injury to the lymphatic system in the arm where lymph nodes have been removed, which could trigger lymphedema.
