In which of the following situations should a nurse report a possible deep vein thrombosis (DVT)?
The woman complains of numbness in the toes and heel of one foot.
The woman has cramping pain in a calf that is relieved when the foot is dorsiflexed.
The veins in the ankle of one of the woman's legs are spider-like and purple.
The calf of one of the woman's legs is swollen, red, and warm to touch.
The Correct Answer is D
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 This symptom is outdated and not considered a definitive sign.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. .

Correct Answer is A
Explanation
Choice A rationale
Massaging the fundus can help contract the uterus and reduce bleeding. Ensuring IV access is crucial for administering medications rapidly. Methylergonovine (Methergine) and oxytocin help stimulate uterine contractions and reduce postpartum hemorrhage, which can be life-threatening.
Choice B rationale
Administering pain medication might be necessary, but it doesn't address the immediate issue of uterine atony and hemorrhage. Surgical intervention is a last resort and should be prepared for only if medical management fails.
Choice C rationale
Reassessing vital signs and monitoring is important, but it doesn't provide an immediate solution to the bleeding and uterine atony. Immediate action to contract the uterus is crucial.
Choice D rationale
Contacting the attending physician is important, but immediate intervention to stop the bleeding and address uterine atony is critical to prevent further complications.
Correct Answer is A
Explanation
Choice A rationale
History of preterm birth is the principal risk factor for predicting preterm birth. Previous preterm births significantly increase the likelihood of subsequent preterm deliveries due to
underlying etiological factors.
Choice B rationale
Low prepregnancy weight is a risk factor but not as significant as a history of preterm birth. It can contribute to complications in pregnancy but does not have the same predictive value.
Choice C rationale
Smoking during pregnancy increases the risk of preterm birth but is not the principal risk factor. It is a modifiable behavior that contributes to poor pregnancy outcomes.
Choice D rationale
Obesity can impact pregnancy outcomes but is not the principal risk factor for preterm birth. It is associated with other complications rather than directly predicting preterm delivery.
