In which clinical situation would the nurse most likely anticipate a fetal bradycardia?
Drug consumed by the mother like cocaine.
Prolonged umbilical cord compression.
Fetal anemia.
Tocolytic treatment using terbutaline.
The Correct Answer is B
Choice A rationale
Cocaine is a stimulant that typically causes fetal tachycardia (an elevated fetal heart rate) due to its sympathomimetic effects, increasing maternal and subsequently fetal heart rate and blood pressure. It does not usually lead to fetal bradycardia.
Choice B rationale
Prolonged umbilical cord compression can lead to fetal bradycardia because it restricts oxygenated blood flow to the fetus. The baroreceptors in the fetus respond to decreased oxygen by slowing the heart rate in an attempt to conserve oxygen and maintain perfusion to vital organs.
Choice C rationale
Fetal anemia, a decrease in red blood cell count, can lead to fetal tachycardia as the heart attempts to compensate for reduced oxygen-carrying capacity by increasing cardiac output. Bradycardia is not a typical initial response to fetal anemia.
Choice D rationale
Terbutaline is a tocolytic medication used to relax the smooth muscle of the uterus and prevent preterm labor. Its side effects often include maternal and fetal tachycardia due to its beta-adrenergic agonist activity.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A"},"F":{"answers":"A"}}
Explanation
- White blood cell count: Expected—mild leukocytosis is normal postpartum due to physiological stress.
- Blood clot size: Expected—small clots, like a pea-sized clot, are common and not concerning unless excessive bleeding occurs.
- Uterine findings: Expected—firm and midline uterus indicating effective involution.
- Lochia findings: Expected—progressing normally without signs of infection (no foul odor).
- Calf findings: Expected—a single varicose vein without tenderness or swelling is not concerning.
- Blood pressure: Expected—within normal postpartum range.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"D"}
Explanation
The nurse should first address the client’s calf findings followed by their stress about discharge.
Rationale for correct answers
Calf findings must be addressed first due to the risk of deep vein thrombosis (DVT), which is a known complication of cesarean delivery and postpartum immobility. The presence of unilateral calf edema (3 cm greater than the right) and tenderness, combined with an elevated D-dimer, strongly suggests a thrombotic process requiring urgent evaluation. If DVT is confirmed, anticoagulation therapy should be initiated promptly to prevent progression to pulmonary embolism.
Stress about discharge should be the second priority, as emotional concerns can affect adherence to postpartum care instructions. Addressing anxiety about recovery, follow-up visits, and newborn care can improve the client’s overall well-being and readiness for discharge.
Rationale for incorrect Response 1 options
- Breast engorgement: Although uncomfortable, this is a transient issue that can be managed with cold compresses and supportive bras. It does not pose an immediate health risk.
- Constipation: Postpartum bowel irregularities are expected after cesarean delivery; stool softeners and hydration can alleviate symptoms without urgency.
- Surgical incision pain: Rated only 2/10, indicating mild pain that does not require immediate intervention beyond routine analgesia.
