ATI RN
ATI Custom OB Exam 1 Summer 2023 Questions
Extract:
Client in second trimester
Question 1 of 5
The nurse should recognize which of the following findings as an expected physiologic change during pregnancy?
Correct Answer: C
Rationale: Increased lordosis occurs as the growing uterus shifts the center of gravity, compensating for posture. Abdominal muscles stretch, pelvic joints loosen, and neck flexion is not typical.
Extract:
Client at 18 weeks of gestation, felt light fluttering in stomach the previous day
Question 2 of 5
The nurse should use which of the following terms to document this finding?
Correct Answer: D
Rationale: Quickening describes the first maternal perception of fetal movement, typically felt at 16-20 weeks, matching the client’s description of light fluttering.
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 3 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 at 38 weeks of gestation, heavy red vaginal bleeding without contractions, no distress, can feel baby moving
Question 4 of 5
The client should undergo an ultrasound to determine which of the following findings?
Correct Answer: C
Rationale: The symptoms suggest placenta previa, where the placenta covers the cervical opening, causing painless bleeding. An ultrasound confirms the placenta’s location. Fetal lung maturity is not a concern at 38 weeks, no contractions are present, and Rh incompatibility is assessed via blood tests.
Extract:
Client 4 hours postpartum, vaginal birth, saturated perineal pad within 10 minutes
Question 5 of 5
Which of the following is the nurse's first action?
Correct Answer: D
Rationale: Massaging the fundus is the first action to address uterine atony, the most likely cause of rapid postpartum bleeding, by promoting uterine contraction to control hemorrhage.
