Question 1 of 5
A client in active labor receives a prescription for oxytocin 6 milliunits/minute intravenously (IV). The IV bag contains oxytocin 10 units in lactated Ringer's 1,000 mL. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)
Correct Answer: 36
Rationale: Calculated as: (6 milliunits/min ÷ 10,000 milliunits) × 1,000 mL = 0.6 mL/min; 0.6 mL/min × 60 min/hour = 36 mL/hour.
Question 2 of 5
A woman in her third trimester of pregnancy has been in active labor for the past 8 hours and has dilated 3 cm. The nurse's assessment findings and electronic fetal monitoring (EFM) are consistent with hypotonic dystocia, and the healthcare provider (HCP) prescribes an oxytocin drip. Which data is most important for the nurse to monitor?
Correct Answer: B
Rationale: Monitoring contraction patterns ensures oxytocin efficacy and prevents hyperstimulation in hypotonic dystocia, critical for labor progression.
Question 3 of 5
A client who is 38 weeks pregnant is concerned her baby might get a communicable disease before any immunizations are given. Which physiological mechanism should the nurse use when responding to the mother's concerns?
Correct Answer: A
Rationale: Passive immunity from maternal antibodies provides newborns with initial protection against communicable diseases, lasting several months until their immune system matures.
Question 4 of 5
A woman who is trying to get pregnant tells the nurse that she was very disappointed several months ago when she was informed that her positive pregnancy test was a false positive. Which method of determining pregnancy provides the greatest degree of accuracy?
Correct Answer: A
Rationale: Vaginal ultrasound directly visualizes the implanted embryo, providing the highest accuracy compared to biochemical tests or subjective symptoms, which can be misleading.
Question 5 of 5
A primipara presents to the perinatal unit describing rupture of the membranes (ROM) occurring 12 hours prior to coming to the hospital. An oxytocin infusion is begun, and 8 hours later the client's contractions are irregular and mild. Based on this data, the nurse plans to monitor which sign more frequently than for the average laboring client?
Correct Answer: B
Rationale: Prolonged ROM increases infection risk, necessitating frequent maternal temperature monitoring to detect chorioamnionitis early.
