A multigravida client at 31 weeks gestation is admitted with confirmed pre-term labor.
As the nurse continues to monitor the client now receiving magnesium sulfate, which assessment findings will the nurse prioritize and report immediately to the RN or health care provider?
Pain in the abdomen, shoulder, or back.
Respiratory depression, hypotension, absent tendon reflexes.
Severe lower back pain, leg cramps, sweating.
Low potassium or elevated glucose, tachycardia, chest pain.
The Correct Answer is B
Choice A rationale
Pain in the abdomen, shoulder, or back can be associated with pre-term labor or other pregnancy complications and should be assessed. However, respiratory depression, hypotension, and absent tendon reflexes are more indicative of magnesium sulfate toxicity and pose an immediate threat to the client's safety.
Choice B rationale
Magnesium sulfate is a central nervous system depressant used to prevent seizures in pre-eclampsia and tocolysis in pre-term labor. Respiratory depression (respiratory rate less than 12 breaths per minute), hypotension (systolic blood pressure less than 90 mmHg or a significant drop from baseline), and absent deep tendon reflexes are signs of magnesium toxicity and require immediate intervention to prevent serious adverse effects.
Choice C rationale
Severe lower back pain, leg cramps, and sweating can be symptoms of pre-term labor or other musculoskeletal issues during pregnancy. While important to assess and manage, they do not represent the same immediate life-threatening risk as magnesium toxicity.
Choice D rationale
Low potassium or elevated glucose levels, tachycardia, and chest pain are not typical side effects of magnesium sulfate. These findings could indicate other underlying medical conditions that need investigation, but they are not the priority assessment related to magnesium sulfate administration compared to signs of toxicity. Normal potassium range is 3.5-5.0 mEq/L, normal fasting glucose is 70-100 mg/dL.

Correct Answer is D
Explanation
Choice A rationale
Puerperal infection, an infection of the reproductive tract after childbirth, is a risk factor for all postpartum women. However, a large newborn size (macrosomia) increases the risk of prolonged labor, increased instrumentation during delivery, and postpartum hemorrhage, which indirectly increases the risk of infection but is not the most direct immediate risk related to the newborn's weight.
Choice B rationale
Retained placental fragments are a risk factor when the placenta does not deliver intact. While a large newborn can sometimes be associated with difficulties during placental delivery, it is not the primary direct risk factor immediately following birth. Uterine atony is a more immediate and direct risk related to uterine overdistension.
Choice C rationale
Thrombophlebitis, the formation of blood clots in the veins, is a postpartum risk factor related to hormonal changes, immobility, and hypercoagulability. While factors like prolonged labor (more common with large babies) can contribute, it is not the most immediate and direct risk in the first few hours postpartum for a woman who delivered a large newborn.
Choice D rationale
A newborn weighing 9 lb 6 oz (4252 g) is considered macrosomic. This large size can lead to overdistension of the uterus during pregnancy and labor. Uterine overdistension impairs the ability of the uterine muscles to contract effectively after delivery, a condition known as uterine atony. Uterine atony is the primary and most immediate risk for postpartum hemorrhage in women who have delivered large newborns. .
Correct Answer is A
Explanation
Choice A rationale
In the immediate postpartum period, it is normal to observe lochia rubra, which is a dark red discharge, and the passage of small blood clots. A firm, midline fundus at the umbilicus indicates that the uterus is contracting effectively to control bleeding. Given these expected findings within the first hour postpartum, continued monitoring is the appropriate initial action.
Choice B rationale
Notifying the provider is usually indicated when there are deviations from the expected postpartum findings, such as excessive bleeding, a boggy uterus, or signs of infection. The current assessment does not indicate such complications.
Choice C rationale
Encouraging the client to empty her bladder is important in the postpartum period as a full bladder can interfere with uterine contraction and lead to increased bleeding. However, with a firm, midline fundus and expected lochia, this is not the priority action over continued monitoring.
Choice D rationale
Increasing the frequency of fundal massage is indicated when the uterus is boggy or not contracting effectively, leading to increased bleeding. The client's fundus is already firm, so increasing massage is not the immediate priority.
