A client with severe hyperemesis gravidarum is admitted to the facility after being cared for at home without success. What would the nurse expect to include in the client's plan of care?
clear liquid diet
administration of labetalol
small frequent meals
nothing by mouth
The Correct Answer is D
A. Clear liquid diet may be appropriate later in treatment once symptoms improve, but it is not typically initiated immediately in a client with severe hyperemesis gravidarum, especially if they are unable to keep any fluids down.
B. Administration of labetalol is used to treat hypertension, particularly in preeclampsia, and is not related to the treatment of hyperemesis gravidarum.
C. Small frequent meals are part of long-term management or mild cases, but for severe hyperemesis gravidarum requiring hospitalization, oral intake is usually withheld initially.
D. Nothing by mouth (NPO) is correct. In severe hyperemesis gravidarum, the client is often kept NPO to rest the gastrointestinal tract and prevent further vomiting. Intravenous (IV) fluids, electrolytes, and sometimes antiemetic medications are administered to manage dehydration and nutritional deficits before gradually resuming oral intake.

Correct Answer is B
Explanation
A. 50mg/hr is not the correct unit for volume, it’s the dose in milligrams.
B. 50 mL/hr is the correct volume to administer to achieve the ordered dose of 2g/hr. Determine the concentration of the solution: The supply is 10g in 250mL. This means the concentration is 10g / 250mL, or 0.04g/mL (since 10g = 10,000mg, this is equivalent to 40mg/mL). Convert the ordered dose to match the concentration: The order is for 2g/hr (which is 2,000mg/hr). Calculate the volume to be infused to deliver the desired dose: Dose = Ordered/concentration= 2000/40= 50 mL/hr
C. 5mg/mL refers to the concentration, not the rate of infusion.
D. 5 mL/hr would administer only 200mg/hr, which is much lower than the ordered dose of 2g/hr.
Correct Answer is B
Explanation
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.
