A laboring client with preeclampsia is prescribed magnesium sulfate 2g/h IVPB.

The pharmacy sent the IV to the unit labeled magnesium sulfate 20g/500mL normal saline.

To administer the correct dose, the nurse should set the pump to deliver how many milliliters per hour?

Choice A rationale

Asthma is a respiratory condition and is not directly linked to an increased risk of placental abruption. While chronic conditions can affect pregnancy, asthma is not a direct risk factor for abruption.

Choice B rationale

Hyperthyroidism is a thyroid condition that can cause complications during pregnancy, but it is not a known risk factor for placental abruption. It affects the mother's metabolism and can impact fetal development, but does not typically cause placental detachment.

Choice C rationale

Previous cesarean delivery is associated with risks such as uterine rupture in future pregnancies, but not specifically with placental abruption. The scar tissue from a cesarean may affect the placenta's position, but does not increase the risk of abruption directly.

Choice D rationale

Hypertension, or high blood pressure, is a significant risk factor for placental abruption. It can damage the blood vessels in the placenta, leading to separation from the uterine wall and resulting in abruption, which can be dangerous for both mother and baby.

Choice A rationale

Preeclampsia is concerning but the blood pressure of 138/82 mm Hg is not critically high at this moment. Preeclampsia is diagnosed by new-onset hypertension and proteinuria or significant end-organ dysfunction in the latter half of pregnancy. Immediate intervention isn't necessary unless symptoms worsen.

Choice B rationale

PPROM (Preterm Premature Rupture of Membranes) at 29 weeks gestation with a temperature of 39.1°C (102.3°F) suggests a possible infection which can be life-threatening for both the mother and the fetus. Prompt medical attention is critical to manage the infection and prevent sepsis.

Choice C rationale

Hyperemesis gravidarum, while uncomfortable and requiring intervention, is less immediately threatening compared to a severe infection. It involves excessive vomiting leading to dehydration and weight loss but doesn't pose an acute threat as severe infection does.

Choice D rationale

Placenta previa with no vaginal bleeding for the last 12 hours indicates stability. However, any bleeding during pregnancy can be concerning and needs careful monitoring, but immediate intervention is not as crucial as for an infection.
