During the active phase of labor, which of the following is a common sign that indicates progress?
Decreased maternal heart rate
Increased intensity and frequency of contractions
Decreased cervical dilation
Decreased intensity and frequency of contractions
The Correct Answer is B
A. Decreased maternal heart rate: Maternal heart rate usually stays the same or may increase slightly due to the physical exertion of labor, but it does not decrease as a sign of labor progression.
B. Increased intensity and frequency of contractions: The active phase of labor is characterized by more frequent and intense contractions that lead to continued cervical dilation and effacement.
C. Decreased cervical dilation: Cervical dilation increases during labor, particularly in the active phase. Decreased dilation is a sign of dysfunctional labor, not normal progress.
D. Decreased intensity and frequency of contractions: Decreasing contraction intensity and frequency would indicate a stall in labor or ineffective labor, not normal progress.

Correct Answer is C
Explanation
A. Duration: Duration refers to how long a single contraction lasts from start to finish, not the time between contractions.
B. Acme: Acme refers to the peak of the contraction, not the time between contractions.
C. Frequency: Frequency refers to the time from the beginning of one contraction to the beginning of the next contraction.
D. Onset: Onset refers to the start of an individual contraction, not the interval between contractions.
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.
