A nurse is preparing to auscultate fetal heart tones for a client who is pregnant. Using Leopold maneuvers, the nurse palpates a round, firm, movable part in the fundal portion of the uterus and a long, smooth surface on the mother's right side. In which of the following maternal quadrants should the nurse auscultate fetal heart tones?

Choice A rationale:
Uterine enlargement greater than expected for gestational age is not a typical finding in a possible ectopic pregnancy. An ectopic pregnancy occurs when the fertilized egg implants outside the uterus, usually in the fallopian tube, and the uterus does not enlarge normally.
Choice B rationale:
Copious vaginal bleeding is not a typical finding in a possible ectopic pregnancy. Vaginal bleeding can occur, but it is not usually copious.
Choice C rationale:
Severe nausea and vomiting are not typically associated with a possible ectopic pregnancy. Nausea and vomiting are common symptoms in early pregnancy, but they are not specific to an ectopic pregnancy.
Choice D rationale:
Pelvic pain is a common finding in a possible ectopic pregnancy. The pain is often sharp, and unilateral, and may be located on one side of the lower abdomen or pelvis.

The correct answer is Choice B, the nipple line.

Choice A rationale: The axillae, or underarms, are not used to measure chest circumference in a newborn. This area does not provide an accurate or consistent measurement of chest size due to the positioning and movement of the baby’s arms.

Choice B rationale: The nipple line is the correct anatomical landmark to use when measuring chest circumference in a newborn. This line is typically used because it provides a consistent and accurate measurement. It is located at the level of the nipples, which is approximately at the mid-chest level. This location allows for a measurement that is representative of the chest size, as it is at the broadest part of the chest.

Choice C rationale: The lower ribcage border is not the correct landmark for measuring chest circumference in a newborn. This area is too low and would not provide an accurate representation of the chest size. The measurement taken at this location would be smaller than the actual chest size, as it is below the broadest part of the chest.

Choice D rationale: The sternal notch is not an appropriate landmark for measuring chest circumference in a newborn. The sternal notch is located at the top of the sternum, near the base of the neck. A measurement taken at this location would not accurately represent the size of the chest, as it is above the broadest part of the chest.
