How would the nurse best analyze the results from a patient sonogram that shows the fetal shoulder is the presenting part? What position?

Correct Answer: A

Rationale: When the sonogram shows the fetal shoulder as the presenting part, it indicates a bridge transverse position. This position means that the baby is lying sideways in the uterus, with one shoulder presenting first. It is essential for the nurse to recognize this position as it may impact the mode of delivery and require additional monitoring to ensure the safe delivery of the baby. Through proper analysis and understanding of the sonogram results, healthcare providers can make informed decisions and provide appropriate care for both the mother and the baby.

Correct Answer: A

Rationale: If the confidence interval includes 1, the difference is not statistically significant.

Correct Answer: A

Rationale: The time period when the fetus is most vulnerable to the effects of teratogens is considered to be between weeks 2 to 8 of pregnancy. This period is known as the embryonic period, during which the organs and major body systems are forming. Exposure to teratogens during this time can lead to structural abnormalities or birth defects. It is crucial for women to be aware of this critical window of susceptibility during preconception counseling to avoid potential harm to the developing fetus.

Correct Answer: A

Rationale: The fertile window typically occurs around days 9 to 25 of a menstrual cycle.

Correct Answer: B

Rationale: Leopold's maneuvers are used to assess fetal position, presentation, and engagement.
