The healthcare provider prescribes magnesium sulfate 4 grams intravenously (IV) to be infused over 20 minutes for a client with preeclampsia.

The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse program the infusion pump?

Choice A rationale

While the estimated amount of fluid can provide some information about the volume of amniotic fluid lost, it is not the most critical piece of information. The amount of fluid can vary and does not necessarily indicate the progression of labor.

Choice B rationale

Any odor noted when the membranes ruptured can be a sign of infection. However, this is not the most crucial information to obtain immediately as it does not directly impact the management of labor.

Choice C rationale

The time the membranes ruptured is the most important information to obtain. This is because the risk of infection increases the longer the time between membrane rupture and delivery.

Knowing the time of rupture helps guide decisions about inducing labor and administering antibiotics to prevent infection.

Choice D rationale

The color and consistency of the fluid can provide information about the presence of meconium or blood, which could indicate fetal distress or placental problems. However, this is not the most critical information to obtain immediately.

Choice A rationale

Abruptio placenta is a condition where the placenta prematurely separates from the uterus. It typically presents with symptoms such as vaginal bleeding, back pain, and frequent contractions. However, the symptoms described by the client do not align with this condition.

Choice B rationale

Chorioamnionitis is an infection of the membranes surrounding the fetus and is associated with prolonged labor. Symptoms include fever, abdominal pain, and fetal tachycardia. The client’s symptoms of pain when the baby moves, a high temperature, and severe abdominal or uterine tenderness on palpation align with this condition.

Choice C rationale

Round ligament strain is a common cause of pain during pregnancy, particularly in the second trimester. It is caused by the stretching of the round ligaments that support the uterus.

However, it does not cause fever or severe abdominal tenderness.

Choice D rationale

While a viral infection could potentially cause a fever, it would not typically cause severe abdominal or uterine tenderness specifically when the baby moves.
