Included in the definition of tachysystole is:
Contraction duration of less than 40 seconds.
Contraction frequency of greater than 5 in 10 minutes.
Contraction intensity of less than 80 mm Hg.
Resting tone of less than 18 mm Hg.
The Correct Answer is B
Choice A rationale
Contraction duration less than 40 seconds doesn't define tachysystole. Tachysystole focuses on frequency, not duration, of contractions over a specific time frame.
Choice B rationale
Contraction frequency of more than 5 in 10 minutes defines tachysystole. This frequency indicates excessive uterine activity, requiring intervention to prevent fetal distress.
Choice C rationale
Contraction intensity less than 80 mm Hg does not define tachysystole. Intensity relates to contraction strength, but tachysystole is about frequency exceeding the normal range.
Choice D rationale
Resting tone less than 18 mm Hg isn't part of tachysystole's definition. Tachysystole pertains to contraction frequency, not resting tone, which measures uterine relaxation between contractions.

Correct Answer is C
Explanation
Choice A rationale
A 15-year-old, G3 P0020, although young, doesn't have an increased risk of uterine rupture related to prior surgical deliveries or other known factors.
Choice B rationale
A 22-year-old, G1 P0000 with eclampsia requires close monitoring for complications related to eclampsia but not specifically for uterine rupture.
Choice C rationale
A 25-year-old, G4 P3003 with a previous cesarean section is at increased risk for uterine rupture due to the scar from the prior surgery which could weaken under the stress of labor.
Choice D rationale
A 32-year-old, G2 P0100's history of a prior fetal demise does not specifically increase the risk of uterine rupture unless accompanied by other risk factors. .
Correct Answer is D
Explanation
Choice A rationale
Numbness in the toes and heel might suggest nerve involvement but is not a typical sign of deep vein thrombosis (DVT), which involves the veins, not nerves.
Choice B rationale
Pain relieved by dorsiflexion (positive Homan's sign) is not reliable for diagnosing DVT. This symptom is outdated and not considered a definitive sign.
Choice C rationale
Spider-like and purple veins suggest superficial varicose veins, not deep vein thrombosis, which affects deeper veins and presents differently.
Choice D rationale
Swelling, redness, and warmth in the calf are classic signs of DVT due to the inflammation and obstruction of deep veins. These symptoms should prompt immediate medical evaluation and intervention. .
