Select the four criteria below that would indicate a category 3 fetal monitor strip.
Tachysystole
Tachycardia with minimal variability
Late decelerations with absent variability
Sinusoidal Pattern
Absent variability with no periodic changes
Bradycardia with absent variability
Late decelerations with moderate variability
Variable decelerations with absent variability
Correct Answer : A,C,D,F
A. Tachysystole refers to excessive uterine contractions, which can cause fetal distress and indicates a category 3 strip.
B. Tachycardia with minimal variability does not qualify as a category 3 pattern; it is concerning but not as severe as category 3.
C. Late decelerations with absent variability are highly concerning for fetal compromise, making the strip category 3.
D. A sinusoidal pattern indicates severe fetal distress and categorizes the strip as category 3.
E. Absent variability with no periodic changes may suggest a non-reassuring pattern but is not categorized as a category 3 strip unless other signs of fetal distress are present.
F. Bradycardia with absent variability is another critical pattern, indicating poor fetal oxygenation and requiring intervention, categorizing it as a category 3 strip.
G. Late decelerations with moderate variability indicate a category 2 strip, not category 3.
H. Variable decelerations with absent variability can be concerning, but it doesn't automatically classify as category 3 without further complications.

C. Uterine contractions (UCs) every 10 minutes do not indicate any immediate concern or contraindication for Terbutaline.
D. A category 1 FHR is reassuring and would not contraindicate the use of Terbutaline.
