A nurse is assisting with the care of a client who has severe preeclampsia and is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe for the nurse to continue the infusion?

Respiratory rate of 16/min.

Heart rate of 60/min.

Urine output of 50 mL in 4 hr.

Diminished deep-tendon reflexes.

Answer and Explanation

The Correct Answer is A

The correct answer is choice A: Respiratory rate of 16/min.

Choice A rationale:

A respiratory rate of 16/min is within the normal range for adults, which is typically between 12 to 20 breaths per minute. In the context of severe preeclampsia, maintaining a normal respiratory rate is crucial when administering magnesium sulfate IV, as one of the signs of magnesium toxicity is respiratory depression. Therefore, a respiratory rate of 16/min indicates that the client is not experiencing respiratory depression and it is safe to continue the magnesium sulfate infusion.

Choice B rationale:

A heart rate of 60/min is at the lower end of the normal range, which is 60 to 100 beats per minute for adults. However, bradycardia or a low heart rate can be a sign of magnesium sulfate toxicity, especially if accompanied by other symptoms such as hypotension or altered mental status. Without additional context, a heart rate of 60/min alone does not necessarily indicate it is unsafe to continue the infusion, but it would require further assessment.

Choice C rationale:

A urine output of 50 mL in 4 hours is significantly below the expected minimum of 30 mL/hour for adults. Adequate urine output is an important indicator of kidney function and is essential for the excretion of magnesium. In the case of magnesium sulfate infusion for severe preeclampsia, a low urine output could indicate renal insufficiency and an increased risk of magnesium toxicity. Therefore, a urine output of 50 mL in 4 hours is a contraindication for continuing the infusion without further evaluation.

Choice D rationale:

Diminished deep-tendon reflexes can be a sign of magnesium toxicity. Deep-tendon reflexes are assessed to monitor for signs of magnesium overdose during infusion, as magnesium acts as a central nervous system depressant at high levels. If deep-tendon reflexes are diminished, it may suggest that the serum magnesium levels are too high, and the infusion should be paused or discontinued to prevent further toxicity.

In summary, the only finding that clearly indicates it is safe to continue the magnesium sulfate infusion is a normal respiratory rate, as provided in choice A. The other options either require further assessment or are indicators of potential magnesium toxicity.

Correct Answer is D

Explanation

Choice A rationale:

Vaginal hematoma is not the most significant risk in the 4th stage of labor. While vaginal hematomas can occur due to trauma during delivery, they are less common and usually manageable compared to other complications.

Choice B rationale:

Hypoglycemia is not a typical complication in the 4th stage of labor. This stage refers to the immediate postpartum period, during which the mother's blood sugar levels may decrease slightly, but it is not the greatest concern at this stage.

Choice C rationale:

Chorioamnionitis is an infection of the fetal membranes and amniotic fluid. While it can be a concern during labor, the question specifically refers to the 4th stage, which occurs after the delivery of the placenta. Chorioamnionitis is more relevant to earlier stages of labor.

Choice D rationale:

Uterine hemorrhage is the greatest risk during the 4th stage of labor. This stage, also known as the "placental stage,”. is when the uterus contracts to expel the placenta. If the uterus fails to contract adequately, it can lead to significant bleeding, known as postpartum hemorrhage. This is a critical concern that requires immediate attention to prevent complications.

Choice E rationale:

Dehiscence, which refers to the reopening of a surgical wound, is not a common complication during the 4th stage of labor. The 4th stage primarily focuses on uterine contraction and placental delivery, making dehiscence less relevant in this context.

A. "We have a neonatal unit here equipped to handle emergencies.". B. "You must be feeling very scared.". C. "Everyone worries about their baby while they are in labor.". D. "You are far enough along that your baby will be just fine.".

Correct Answer is B

Explanation

The correct answer is choice B: “You must be feeling very scared.” This response is an example of therapeutic communication, where the nurse acknowledges the client’s feelings and provides emotional support without making assumptions or giving false reassurances.

Choice A rationale: While it’s true that the presence of a neonatal unit equipped to handle emergencies is reassuring, this response does not address the client’s immediate emotional needs or fears. It’s important for the nurse to recognize and validate the client’s feelings rather than focusing solely on the facilities available.

Choice B rationale: This choice demonstrates empathy and understanding. It allows the client to express their feelings and concerns, which is a crucial aspect of providing emotional support during labor. By acknowledging the client’s potential fear, the nurse opens the door for further communication and support.

Choice C rationale: This response minimizes the client’s individual feelings by suggesting that everyone has the same worries. It can make the client feel that their concerns are not unique or taken seriously, which is not conducive to establishing trust or providing individualized care.

Choice D rationale: This choice provides false reassurance. At 32 weeks of gestation, while the prognosis for the baby is generally good, there are still risks associated with preterm birth. It’s important not to make definitive statements about outcomes that cannot be guaranteed.
