A nurse is caring for a client who is receiving intravenous magnesium sulfate for preeclampsia.
Which assessment finding would alert the nurse to suspect magnesium toxicity?
Rapid pulse.
Tingling in toes.
Cool skin temperature.
Absent deep tendon reflexes.
The Correct Answer is D
Choice A rationale
A rapid pulse is not typically associated with magnesium toxicity. Magnesium toxicity more commonly affects the nervous and muscular systems.
Choice B rationale
Tingling in toes can be a sign of early magnesium sulfate effects but not necessarily toxicity. It may indicate that the medication is starting to affect the nervous system.
Choice C rationale
Cool skin temperature is not a common sign of magnesium toxicity. Symptoms of magnesium toxicity are more related to neuromuscular and respiratory function.
Choice D rationale
Absent deep tendon reflexes are a key indicator of magnesium toxicity. This finding suggests that magnesium levels are high enough to depress neuromuscular function, requiring immediate medical intervention. .

Correct Answer is B
Explanation
Choice A rationale
Uteroplacental insufficiency typically results in late decelerations, not a sudden drop in fetal heart rate, which is more commonly caused by umbilical cord compression.
Choice B rationale
Umbilical cord compression can cause variable decelerations, which are characterized by a sudden drop in fetal heart rate. This occurs due to the umbilical cord being compressed,
leading to decreased blood flow and oxygen to the fetus.
Choice C rationale
Maternal bradycardia refers to a slow maternal heart rate and does not directly cause changes in the fetal heart rate pattern.
Choice D rationale
Fetal head compression typically causes early decelerations, which are gradual decreases in fetal heart rate that occur with contractions and are usually benign.
Correct Answer is C
Explanation
Choice A rationale
Placenta formation begins shortly after implantation, but it continues to develop throughout the first trimester and into the early second trimester, making it less precise to attribute the
first 8 weeks solely to this process.
Choice B rationale
Fertilization occurs within the first week after ovulation, marking the beginning of pregnancy, but it is a singular event that happens prior to the developmental processes vulnerable to teratogens.
Choice C rationale
Organogenesis is the critical period during which the major organs and structures of the fetus form, typically occurring between the third and eighth weeks of gestation. This is the
time when the fetus is most susceptible to the effects of teratogens, which can cause congenital anomalies.
Choice D rationale
Implantation occurs approximately 6-10 days after fertilization, embedding the blastocyst into the uterine lining. While crucial, it is not the primary period when teratogenic effects are
most significant, as this happens during organogenesis.
