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?

A.

Rapid pulse.

B.

Tingling in toes.

C.

Cool skin temperature.

D.

Absent deep tendon reflexes.

Answer and Explanation

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 ["A","B","C","F"]

Explanation

Choice A rationale:

A postpartum temperature of 100.4°F (38.0°C) or higher may indicate an infection. Infections can occur after delivery, particularly if there was a manual extraction of the placenta, as in

this case. Close monitoring and further assessment are necessary to ensure the client does not develop sepsis or other complications.

Choice B rationale:

Fundal tone should be firm and well-contracted to prevent excessive bleeding postpartum. A boggy, midline fundus suggests that the uterus is not contracting effectively, increasing the

risk for postpartum hemorrhage. This requires immediate attention and intervention to ensure adequate uterine tone and control bleeding.

Choice C rationale:

Lochia should be monitored for quantity, color, and the presence of clots. Heavy lochia with small clots indicates that the client may be experiencing postpartum hemorrhage, which is a

significant concern. This can be related to uterine atony, retained placental fragments, or coagulopathies and warrants prompt evaluation and intervention.

Choice D rationale:

A respiratory rate of 17/min is within the normal adult range (12-20/min) and does not require follow-up. There are no signs of respiratory distress or abnormalities in this case, indicating

that the client's respiratory status is stable and does not necessitate further evaluation.

Choice E rationale:

A white blood cell count of 12,000/mm³ is within the expected range for postpartum women, where normal values can be elevated due to physiological stress and inflammation from

delivery. This level does not indicate infection or pathology and does not require follow-up in the context provided.

Choice F rationale:

Blood pressure of 144/92 mmHg is elevated and concerning, particularly in a postpartum client with a history of chronic hypertension and gestational diabetes. This could signal

postpartum preeclampsia or other hypertensive disorders, requiring careful monitoring and management to prevent complications like seizures, stroke, or organ damage.

Correct Answer is B

Explanation

Choice A rationale

The fetal heartbeat cannot typically be heard via Doppler as early as 4 weeks of pregnancy. At this stage, the heart is still developing, and it is too soon for external detection with a Doppler device.

Choice B rationale

The fetal heartbeat is generally detectable by an external Doppler device around 10-12 weeks of pregnancy. This is the period when the heartbeat is strong enough to be picked up by the device.

Choice C rationale

Feeling the baby move, known as "quickening," typically occurs around 18-24 weeks of pregnancy, not 6 weeks. This sensation is different from hearing the heartbeat.

Choice D rationale

While the heart begins to form around week 5, it is not detectable by Doppler at 6 weeks. The technology does not have the sensitivity to detect such an early heartbeat externally.
