50 grams of Magnesium sulfate is added to 1L of Lactated Ringers.
After giving an initial loading dose, the nurse is to infuse a maintenance dose of 2 gm/hr. What rate should the IV pump be set at?
10 mL/hr
20 mL/hr
30 mL/hr
40 mL/hr
The Correct Answer is D
Step 1 is to calculate the total amount of Magnesium sulfate in the solution. This is done by multiplying the amount of Magnesium sulfate per mL (which is 50g/L or 0.05g/mL) by the total volume of the solution (which is 1000mL). So, 0.05g/mL × 1000mL = 50g.
Step 2 is to calculate the rate of the IV pump. The maintenance dose is 2g/hr. So, if there are 50g in 1000mL, then 2g would be in (2g ÷ 50g) × 1000mL = 40mL. Therefore, the IV pump should be set at 40 mL/hr.

Correct Answer is []
Explanation
The client is most likely experiencing Normal labor progression. The retraction of the fetal head against the maternal perineum, regular and progressing contractions, and full dilation of the cervix are all signs of normal labor progression.
Actions: The nurse should:
1. Encourage the client to push during contractions. This will help the baby move down the birth canal.
2. Monitor fetal heart rate. This is crucial to ensure the baby is not in distress.
Parameters: The nurse should monitor:
1. Frequency of contractions. This will help assess the progress of labor.
2. Fetal heart rate. Any abnormalities could indicate fetal distress, which would require immediate medical attention.
Correct Answer is A
Explanation
Choice A rationale
The client’s symptoms of elevated blood pressure, 3+ edema in the lower extremities, and 3+ proteinuria are indicative of preeclampsia. Preeclampsia is a complication of pregnancy that begins after 20 weeks of gestation in women whose blood pressure had previously been in the standard range. It is associated with high blood pressure and signs of damage to another organ system, often the liver and kidneys. In this case, the nurse should initiate seizure precautions and monitor the client’s neurological status and liver function studies. Seizure precautions are necessary because eclampsia, a severe form of preeclampsia, can lead to seizures. Monitoring neurological status can help detect changes in the client’s condition, and liver function studies can help assess the impact of preeclampsia on the liver.
Choice B rationale
While the client does have a history of chronic hypertension, the current symptoms suggest a condition more severe than chronic hypertension. Administering antihypertensive medication and monitoring blood pressure and heart rate would be appropriate actions for managing chronic hypertension, but they may not be sufficient to address the client’s current condition.
Choice C rationale
Gestational diabetes is a condition characterized by high blood sugar levels that develop during pregnancy in women who did not have diabetes before pregnancy. The client’s symptoms do not indicate gestational diabetes. While administering insulin and monitoring blood glucose levels and fetal heart rate would be appropriate actions for managing gestational diabetes, they do not address the client’s current symptoms.
Choice D rationale
Preterm labor refers to regular contractions of the uterus resulting in changes in the cervix that start before 37 weeks of pregnancy. The client’s symptoms do not suggest preterm labor. Administering tocolytics and monitoring contraction pattern and cervical dilation would be appropriate actions for managing preterm labor, but they do not address the client’s current symptoms.
