Nurses' Notes
0900:
Client who is at 38 weeks of gestation presents to the antepartum unit with uterine contractions, dark red vaginal bleeding, and abdominal pain that started approximately 45 min prior to arrival. Rates abdominal pain a 7 on a scale of 0 to 10. Client reports, "My blood pressure has been high during the pregnancy."
Home Medications: prenatal multivitamin, methyldopa 250 mg PO twice daily Physical Exam:
General: tearful, anxious
Cardiovascular: S1, S2, no murmur
Respiratory: bilateral breath sounds clear
Abdomen: Uterine hypertonicity with a board-like abdomen, tenderness noted upon palpation of left upper quadrant
FHR: 116/min, minimal variability noted
Rationale:
Dark red vaginal bleeding: This could indicate a serious complication such as placental abruption, which can lead to fetal and maternal distress. Dark red bleeding is often associated with this condition and requires immediate follow-up to determine the source and to prevent further complications.
Uterine hypertonicity with a board-like abdomen: Uterine hypertonicity and a "board-like" abdomen may suggest uterine contractions that are intense or sustained, which could be associated with placental abruption or other serious obstetric complications. This finding needs follow-up to assess for uterine rupture, abruption, or other causes of uterine distress.
Pain score of 7/10: The client's moderate-to-severe pain (rated 7/10) requires follow-up to manage pain and evaluate for its cause. Pain related to placental abruption or other complications may be severe and should be managed appropriately.
FHR of 116/min with minimal variability: A fetal heart rate (FHR) of 116/min is within the normal range, but minimal variability could suggest fetal distress or compromise. Follow-up is needed to continuously monitor fetal well-being and assess for any changes in FHR patterns.
Correct Answer is ["6"]
Explanation
Step 1: Calculate the desired dose per minute.
Desired dose = 4 mcg/kg/min * 80 kg = 320 mcg/min
Step 2: Convert mcg/min to mg/hr.
320 mcg/min * 60 min/hr = 19200 mcg/hr = 19.2 mg/hr
Step 3: Calculate the concentration of dopamine in the solution.
Concentration = 800 mg / 250 mL = 3.2 mg/mL
Step 4: Calculate the volume to be infused per hour.
Volume/hr = Dose rate (mg/hr) / Concentration (mg/mL)
Volume/hr = 19.2 mg/hr / 3.2 mg/mL = 6 mL/hr
Therefore, the nurse should set the IV infusion to deliver 6 mL/hr.
