The nurse is caring for a client in labor who has refused epidural anesthesia. An order was placed for Stadol 3mg IV Q4h PRN pain. The drug is supplied 2 mg per ml. How much of the medication should the nurse give?

A. Dark red vaginal bleeding is often seen in placental abruption. The blood from an abruption is typically dark red (indicating that it is older blood) and may be mixed with amniotic fluid, making it more challenging to assess. However, the bleeding can sometimes be concealed, especially in complete abruption or retroplacental hemorrhage, where blood accumulates behind the placenta.

B. Absence of pain is incorrect. In fact, placental abruption is typically associated with abdominal pain, which can be severe and often comes on suddenly. Pain occurs due to the detachment of the placenta from the uterine wall and subsequent irritation or bleeding into the uterine cavity.

C. Insidious onset is incorrect. Placental abruption usually has a sudden or acute onset of symptoms, such as vaginal bleeding and abdominal pain. An insidious onset would be more suggestive of other conditions, such as placenta previa.

D. Absent fetal heart tones is a critical finding. Placental abruption can cause fetal distress or fetal death, especially if the abruption is severe. Absent fetal heart tones are a sign of fetal compromise or death resulting from the disruption of placental blood flow.

A. 8.4 mEq/L is above the therapeutic range and may indicate magnesium toxicity. Levels greater than 7.5–8 mEq/L can lead to loss of deep tendon reflexes, and higher levels can cause respiratory depression and cardiac arrest.
B. 6.1 mEq/L falls within the therapeutic range for magnesium sulfate when used to treat severe preeclampsia, which is generally 4.8–8.4 mEq/L (or 4–7 mEq/L depending on the source and unit of measurement). This level is considered safe and effective for preventing seizures.
C. 10.8 mEq/L is too high and indicates magnesium toxicity, placing the patient at risk for serious complications like respiratory or cardiac arrest.
D. 3.3 mEq/L is below the therapeutic range, suggesting that the dose may be inadequate to prevent eclamptic seizures in a woman with severe preeclampsia.
