Which of the following findings would be most concerning to the nurse caring for a newborn?

A) Wash your hands before and after you use the bathroom and change your sanitary pad:
The most important instruction for preventing postpartum infection is proper hand hygiene. The risk of infection in the postpartum period is high, especially because the perineum and cervix are healing after delivery. By washing hands before and after using the bathroom or changing sanitary pads, the mother reduces the risk of introducing harmful bacteria into the vaginal area. Proper hand hygiene helps minimize the risk of urinary tract infections (UTIs), wound infections, and endometritis, which are all common postpartum complications.

B) Do not take tub baths for eight weeks:
While it is true that taking tub baths can potentially introduce bacteria into the vaginal area, particularly if the perineum is healing from a tear or episiotomy, this is a secondary concern. The priority is hand hygiene, which directly prevents infection by limiting bacterial exposure. The recommendation to avoid tub baths is generally valid for the first 6 weeks, but it is less critical than hand washing.

C) Use tampons instead of pads as they are better at inhibiting bacterial growth:
Using tampons is not recommended in the postpartum period because they can increase the risk of toxic shock syndrome and can irritate the vaginal area or interfere with uterine healing. Pads are preferred to absorb lochia (postpartum discharge) and are safer for vaginal healing. Tampons do not inhibit bacterial growth more effectively than pads, and the use of tampons can actually increase the risk of infection, so this option is incorrect.

D) Douche with a mild antiseptic twice a day for two weeks, starting at day three:
Douching is not recommended during the postpartum period. It can disrupt the natural vaginal flora, increase the risk of infections like vaginitis, and delay the healing process. The vagina has its own natural defense mechanisms, and douching with antiseptics is unnecessary and can do more harm than good. Instead, the focus should be on keeping the area clean and dry and practicing proper hand hygiene.

A) 2 to 3 oz (60 to 90 mL):
To determine the appropriate amount of formula for this infant, first calculate the total fluid requirements for the day. The infant weighs 6 lb (2722 g), and newborns typically need 73 mL of fluid per pound of body weight per day.
6 lb × 73 mL = 438 mL of fluid required daily.
Since the infant is fed every 4 hours, this equates to approximately 6 feedings in a 24-hour period.
438 mL ÷ 6 feedings = 73 mL per feeding.
Converting this to ounces (since 1 oz = 30 mL), the infant would need about 2.5 oz per feeding. Therefore, 2 to 3 oz (60 to 90 mL) per feeding is appropriate to meet the infant's daily fluid needs.

B) 1 to 1.5 oz (30 to 45 mL):
This amount is insufficient for the infant’s daily fluid needs. At 1 to 1.5 oz per feeding, the total intake for the day would be only 180 to 270 mL, which is well below the required 438 mL. This could lead to dehydration and inadequate nourishment.

C) 4 to 5 oz (120 to 150 mL):
This amount is excessive for a 3-day-old infant. Newborns typically consume much smaller amounts at each feeding due to their smaller stomach capacity. Overfeeding could lead to discomfort and potential digestive issues.

D) 3 to 4 oz (90 to 120 mL):
While this range is closer to the required amount, it is still slightly too much for a 3-day-old infant. At this age, the recommended amount is closer to 2.5 oz per feeding, so 3 to 4 oz may be excessive and could contribute to overfeeding, which might be uncomfortable for the infant.
