A nurse is assessing a newborn who was born vaginally with vacuum extractor assistance. The nurse notes swelling over the newborn's head that crosses the suture line. The nurse should identify the swelling as which of the following findings?

Choice A rationale:

When late decelerations are noted in the fetal heart rate (FHR) tracing, it indicates that the fetal oxygen supply may be compromised. The nurse should first change the client's position, such as moving her to the left lateral position or a hands-and-knees position, to improve uteroplacental blood flow and relieve pressure on the vena cava.

Choice B rationale:

Palpating the uterus to assess for tachysystole is not the priority action when late decelerations are observed. Tachysystole refers to excessively frequent uterine contractions and may contribute to fetal distress, but the immediate concern is addressing the decelerations.

Choice C rationale:

Increasing the client's IV infusion rate may not address the underlying cause of late decelerations. While maintaining hydration is important, it's not the first action to take in this situation.

Choice D rationale:

Administering oxygen at 10 L/min via a non-rebreather mask may be beneficial for the client and fetus, but it is not the first action to take. The nurse should address the position change first to improve oxygenation through better blood flow before considering supplemental oxygen.

Choice A rationale:

Assisting the client to void is a priority intervention in this situation. A full bladder can displace the uterus and prevent it from contracting effectively, leading to a boggy and high- positioned fundus. After the client empties her bladder, the nurse should reassess the fundus to ensure it has descended to its appropriate location, which is usually at or just below the level of the umbilicus.

Choice B rationale:

Documenting the findings as within normal limits is incorrect because a firm, displaced fundus that is 3 cm above the umbilicus is not considered normal. This finding indicates that the uterus is not contracting adequately, and the nurse should take appropriate actions to address the issue.

Choice C rationale:

Gently massaging the client's fundus is not the correct intervention in this case. Massaging a firm fundus could cause uterine irritation and should be avoided. Instead, the nurse should encourage the client to empty her bladder, which often helps the uterus contract and descend to its proper position.

Choice D rationale:

Encouraging the client to ambulate may be helpful in some cases to promote uterine contractions and involution. However, in this situation, the priority is to address the full bladder, as it is a common cause of a displaced and high fundus shortly after delivery.
