A client who is 7 days postpartum calls the provider's office and reports pain, swelling, and redness of her left calf. Besides the client seeing the provider, which of the following interventions should the nurse suggest?

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.

Choice A rationale: Placing the infant in a prone position (lying face down) after feeding is not recommended for a baby with gastroesophageal reflux. The prone position can increase the risk of choking and is not helpful in managing reflux.
Choice B rationale: For an infant with gastroesophageal reflux, placing the baby in an upright position after feeding can help prevent or reduce reflux episodes. Keeping the infant in an upright position allows gravity to assist in keeping stomach contents down and reduces the likelihood of reflux into the esophagus.
Choice C rationale: Placing the infant on the right side after feeding is also not recommended for managing gastroesophageal reflux. The right-side position may not be as effective in preventing reflux as the upright position.
Choice D rationale: Placing the infant on the left side after feeding is not the preferred position for managing gastroesophageal reflux. The left-side position may not be as effective in preventing reflux as the upright position.
