ATI Maternal Newborn Proctored

Correct Answer: B

Rationale: When measuring a newborn's chest circumference, the appropriate anatomical landmark to use is the nipple line. This point is consistent and allows for accurate and standardized measurements across all newborn assessments. The sternal notch is not typically used for chest circumference measurements in newborns. The xiphoid process is located at the lower end of the sternum and is not an appropriate landmark for chest circumference measurement. The fifth intercostal space is typically used for locating the point of maximal impulse (PMI) during cardiac assessments, not for measuring chest circumference.

Correct Answer: D

Rationale: In the postpartum period, the presence of lochia rubra and small clots along with a firm, midline fundus at the umbilicus is considered normal. In this situation, the appropriate action is to document the findings and continue to monitor the client. Changes in the amount and character of lochia, deviation of the fundus from the midline, or fundal height above or below the expected level may indicate a need for further intervention. Encouraging bladder emptying is important but not the priority in this scenario. Notify the healthcare provider if there are signs of abnormal postpartum bleeding or fundal abnormalities. Therefore, choice D is the correct answer. Choices A, B, and C are incorrect because at this stage, there are no signs of abnormality that require immediate notification of the healthcare provider, increased frequency of fundal massage, or immediate bladder emptying.

Correct Answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.

Correct Answer: D

Rationale: The correct sequence of maternal changes during pregnancy is as follows: Amenorrhea (absence of menstrual periods), Goodell's sign (softening of the cervix), Quickening (first fetal movements felt by the mother), and Lightening (baby descending into the pelvis). These changes occur at different stages of pregnancy and are important indicators of fetal development and maternal adaptation. Choice A is correct as it is the initial change indicating possible pregnancy. Choices B, C, and D follow in the correct order of occurrence during pregnancy. Choices B, C, and D are incorrect as they do not follow the correct sequence of maternal changes.

Correct Answer: D

Rationale: Fetal heart tones above the umbilicus at midline are indicative of a breech presentation, specifically a frank breech position. In a frank breech position, the baby's buttocks are presenting first, which aligns with the fetal heart tones being above the umbilicus. This position indicates that the baby is not in the normal head-down position for birth, which can impact the delivery process and may require specific interventions. Cephalic presentation (Choice A) is the normal head-down position for birth, transverse lie (Choice B) is when the baby is positioned horizontally in the uterus, and posterior position (Choice C) refers to the baby's back being positioned towards the mother's back.
