A nurse is caring for a pregnant client with severe preeclampsia who is receiving IV magnesium sulfate.
Select all nursing interventions that apply in the care for the client.
Monitor deep tendon reflexes hourly.
Notify the physician if urinary output is less than 30 ml per hour.
Keep calcium gluconate on hand in case of a magnesium sulfate overdose.
Monitor maternal vital signs every 6 hours.
Monitor intake and output hourly.
Monitor renal function and cardiac function closely.
Correct Answer : A,B,C,E,F
Choice A rationale
Hourly monitoring of deep tendon reflexes is crucial in clients receiving magnesium sulfate for severe preeclampsia. Magnesium sulfate acts as a central nervous system depressant, and diminished or absent deep tendon reflexes (normal range: 2+ to 4+) can indicate magnesium toxicity, necessitating immediate intervention to prevent serious complications like respiratory depression.
Choice B rationale
A urinary output of less than 30 mL per hour signals potential renal hypoperfusion, which can be exacerbated by severe preeclampsia and magnesium sulfate administration. Reduced kidney function can lead to the accumulation of magnesium, increasing the risk of toxicity. Prompt notification of the physician allows for timely adjustments in the treatment plan.
Choice C rationale
Calcium gluconate is the antidote for magnesium sulfate overdose. Having it readily available is essential in case the client exhibits signs of magnesium toxicity, such as respiratory depression, severe hypotension, or loss of reflexes. Prompt administration of calcium gluconate can reverse the effects of magnesium and prevent life-threatening complications.
Choice E rationale
Hourly monitoring of intake and output is vital to assess fluid balance and renal function in pregnant clients with severe preeclampsia receiving magnesium sulfate. Accurate measurement helps in detecting oliguria, a sign of worsening preeclampsia or magnesium toxicity, allowing for timely interventions to maintain adequate hydration and prevent complications.
Choice F rationale
Severe preeclampsia significantly impacts both renal and cardiac function due to widespread vasoconstriction and endothelial dysfunction. Close monitoring of these systems through laboratory tests (e.g., serum creatinine, BUN, electrolytes, ECG) and clinical assessments is essential to detect and manage potential complications such as acute kidney injury, heart failure, and arrhythmias.

Correct Answer is D
Explanation
Choice A rationale
Fetal hypoxemia, a deficiency in oxygen reaching the fetal tissues, typically manifests as late decelerations in the fetal heart rate tracing, which reflect uteroplacental insufficiency. While severe hypoxemia can lead to various FHR patterns, variable decelerations are more directly associated with mechanical factors affecting the umbilical cord.
Choice B rationale
Altered fetal cerebral blood flow can be a consequence of various factors, including hypoxemia and cord compression, and can influence the fetal heart rate. However, variable decelerations are specifically caused by events that directly impede blood flow through the umbilical vessels rather than a generalized alteration in cerebral circulation.
Choice C rationale
Uteroplacental insufficiency, a condition where the placenta is unable to deliver an adequate supply of oxygen and nutrients to the fetus, typically results in late decelerations, indicating fetal distress due to chronic hypoxia. Variable decelerations, in contrast, have a more abrupt onset and recovery, reflecting acute changes in umbilical cord blood flow.
Choice D rationale
Umbilical cord compression occurs when the umbilical cord, which carries oxygen and nutrients to the fetus, is squeezed or constricted. This compression leads to a transient decrease in fetal blood flow and oxygenation, resulting in a rapid drop and subsequent return of the fetal heart rate, which is characteristic of variable decelerations. The shape, timing, and abrupt nature of variable decelerations directly correlate with the intermittent pressure on the umbilical cord.
Correct Answer is B
Explanation
Choice A rationale
Thoroughly cooking meat to an internal temperature of 160°F (71°C) kills the Toxoplasma gondii parasite, thus preventing transmission through ingestion of contaminated meat. This is a crucial preventive measure recommended for pregnant women.
Choice B rationale
Drinking unpasteurized milk poses a risk of toxoplasmosis, as well as other foodborne illnesses like listeriosis and brucellosis. Pasteurization is a process that heats milk to a specific temperature for a set time, killing harmful bacteria and parasites, including Toxoplasma gondii. Therefore, this statement indicates a need for further instruction, as pregnant women should consume only pasteurized dairy products.
Choice C rationale
Cat feces can contain oocysts of Toxoplasma gondii, which can become infectious after a period of sporulation. Avoiding contact with materials possibly contaminated with cat feces, such as litter boxes and garden soil, is an important measure to prevent toxoplasmosis.
Choice D rationale
Handling raw meat can expose a person to Toxoplasma gondii cysts. Avoiding touching mucous membranes of the mouth or eyes after handling raw meat and washing hands thoroughly reduces the risk of self-inoculation with the parasite.
