ATI Custom OB Exam 1 Summer 2023 Questions
Extract:
Client in labor, oxytocin (Pitocin) infusing at 15 mu/minute, has 20 units of Pitocin in 1000 mL of Normal Saline IV solution
Question 1 of 5
If this client is receiving 15 mu/min, then how many mL/hr would her IV infusion pump be set at? Be sure to enter the number AND the unit of measurement (mL).
Correct Answer: 45 mL/hr
Rationale:
To find the infusion rate, convert the dose to mL/hr. The solution has 20 units (20,000 milliunits) in 1000 mL, so the concentration is 20,000 mu / 1000 mL = 20 mu/mL. The dose is 15 mu/min, so per hour: 15 mu/min × 60 min/hr = 900 mu/hr. Volume per hour: 900 mu/hr ÷ 20 mu/mL = 45 mL/hr.
Extract:
Client pregnant, BMI of 26.5
Question 2 of 5
Which of the following statements is an appropriate response by the nurse?
Correct Answer: B
Rationale: For a BMI of 26.5 (overweight), 15-25 pounds is the recommended weight gain to support healthy maternal and fetal outcomes, minimizing complications like gestational diabetes.
Extract:
Client regarding how to reduce the risk of giving birth to a newborn who has a neural tube defect
Question 3 of 5
Which of the following instructions by the nurse is appropriate?
Correct Answer: B
Rationale: Folic acid is critical for neural tube development, and adequate intake (at least 400 mcg daily) before and during early pregnancy reduces the risk of neural tube defects like spina bifida. Iron is unrelated to neural tube defects, aspirin doesn’t cause them, and while alcohol avoidance is important, it’s not linked to neural tube defects.
Extract:
Client at 34 weeks of gestation, suspected placenta previa
Question 4 of 5
Which of the following actions should the nurse take?
Correct Answer: B
Rationale: An external fetal monitor assesses fetal well-being and contractions without risking placental disruption. Rectal/vaginal exams or ice could exacerbate bleeding in placenta previa.
Extract:
Client possible ectopic pregnancy at 8 weeks of gestation
Question 5 of 5
Which of the following findings should the nurse expect?
Correct Answer: A
Rationale: Pelvic pain is the hallmark of ectopic pregnancy due to tubal stretching or rupture. Severe nausea, copious bleeding, or excessive uterine enlargement are not typical.
