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.

Correct Answer is B
Explanation
Rationale:
A. Refitting the diaphragm is recommended after significant weight change, not when changing partners.
B. Leaving the diaphragm in place for at least 6 hours after intercourse ensures effective contraception.
C. Lubricant is not placed inside the diaphragm but on the rim or used with spermicide.
D. Leaving the diaphragm in during menstruation increases the risk of toxic shock syndrome.
Correct Answer is ["A","C"]
Explanation
A. Maternal hypotension is a common side effect of epidural anesthesia, which can reduce uteroplacental blood flow and lead to late decelerations in the fetal heart rate.
B. Maternal tachycardia is not typically associated with late decelerations; it is more often seen with early decelerations or fetal distress.
C. An IV bolus prior to the epidural helps maintain blood volume and prevent hypotension. Without it, the risk of hypotension and subsequent late decelerations increases.
D. Placenta previa typically causes painless vaginal bleeding and may lead to abnormal FHR patterns, but it is not a direct cause of late decelerations post-epidural.
