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

A) Axillary temp of 96.9F (36.0 C) after 30 minutes of skin-to-skin contact with the mother:
A temperature of 96.9°F (36.0°C) is lower than the expected normal range for a newborn, which is typically between 97.7°F (36.5°C) and 99.5°F (37.5°C). However, after 30 minutes of skin-to-skin contact with the mother, the temperature is likely to increase as the infant benefits from the warmth of the mother's body. If the temperature does not rise or if it continues to decrease, further intervention would be necessary.

B) Respiratory rate of 58 during assessment at beginning of shift:
Newborns may have slightly irregular and rapid breathing patterns, especially right after birth, but this is not a cause for concern unless accompanied by signs of respiratory distress, such as retractions, flaring, or grunting.

C) Heart rate of 162 while crying vigorously after a diaper change:
It is not uncommon for a newborn to have an elevated heart rate when upset or crying. A heart rate of 162 while crying is expected and does not indicate a problem. Once the baby calms down, the heart rate will likely return to its baseline.

D) No void after 8 hours of life:
The absence of a urine output within the first 8 hours of life is concerning and requires immediate follow-up. Newborns typically void within the first 24 hours, and if there is no urine output by 8 hours, it could indicate a potential problem such as dehydration, urinary tract obstruction, or renal dysfunction. A healthcare provider should be notified promptly for further assessment and intervention.

A) Massage the fundus:
The first priority in this situation is to massage the fundus to help control potential postpartum hemorrhage caused by uterine atony. A boggy fundus (soft and not firm) suggests that the uterus is not contracting effectively, which can lead to excessive bleeding. Massaging the fundus stimulates uterine contractions, which can help reduce bleeding by compressing the blood vessels that were supplying the placenta. The nurse should begin with this intervention immediately to address the most likely cause of the bleeding.

B) Take the patient's blood pressure:
While vital signs such as blood pressure are important for assessing shock or ongoing hemorrhage, massaging the fundus takes priority in this scenario to directly address the cause of the bleeding. Taking the blood pressure is not the most immediate intervention for this specific situation because the primary issue here is uterine atony, not hemodynamic instability (although it will need to be assessed shortly thereafter).

C) Start an IV:
Starting an IV may be important if there is significant blood loss, but it is not the first priority in this scenario. The nurse should first focus on stabilizing the uterus by massaging the fundus. IV access will become more critical if the bleeding is not controlled after the fundus is massaged and other interventions are required.

D) Have the patient empty her bladder:
While a full bladder can sometimes displace the uterus and cause it to be less effective at contracting, this is a secondary concern. The first priority is to address the uterine atony by massaging the fundus. Once the fundus is firm and bleeding is under control, the nurse can then consider having the patient empty her bladder to ensure it isn't interfering with the uterus' ability to contract.
