A disadvantage of internal fetal monitoring is:
An artifact on the printout is very common
Accurate information regarding FHR variability is not possible
It cannot provide data about the uterine resting tone
It is invasive and increases the risk for uterine infection
The Correct Answer is A
A. An artifact on the printout is very common. Artifacts are more common with external fetal monitoring, not internal fetal monitoring.
B. Accurate information regarding FHR variability is not possible. Internal fetal monitoring provides more accurate information about fetal heart rate (FHR) variability compared to external monitoring.
C. It cannot provide data about the uterine resting tone. Internal monitoring can measure the uterine resting tone more accurately than external methods.
D. It is invasive and increases the risk for uterine infection. Internal fetal monitoring requires inserting a device into the uterus, making it invasive and increasing the risk of infection.

Correct Answer is D
Explanation
A. Heart rate of 55/min. A heart rate of 55/min is bradycardia, which may indicate magnesium toxicity. This is a concerning sign and does not indicate safety to continue.
B. Urine output of 50 mL in 4 hr. A urine output of only 50 mL in 4 hours is too low (less than 30 mL/hr is concerning) and may indicate toxicity, since magnesium sulfate is excreted via the kidneys.
C. Diminished deep-tendon reflexes. Diminished deep-tendon reflexes (DTRs) may indicate magnesium toxicity. DTRs are monitored to assess for toxicity.
D. Respiratory rate of 16/min. A normal respiratory rate (12-20 breaths per minute) indicates that the magnesium sulfate has not caused respiratory depression, a sign of magnesium toxicity.
Correct Answer is B
Explanation
A. Flumazenil: Flumazenil is an antidote for benzodiazepine overdose, not for magnesium toxicity.
B. Calcium gluconate. Calcium gluconate is the antidote for magnesium sulfate toxicity and should be administered when signs of toxicity, such as respiratory depression, occur.
C. Naloxone: Naloxone is an antidote for opioid overdose, not magnesium toxicity.
D. Protamine sulfate: Protamine sulfate is the antidote for heparin overdose, not magnesium toxicity.
