A 24-year-old G2P1 presents to labor and delivery in latent labor at 37 weeks. Her contractions are every 5-6 minutes, and her cervix is 2 cm/80% effaced/-1 station. She is Group B Strep positive and is receiving penicillin IV for prophylaxis. 

Her pregnancy has been complicated by gestational hypertension, and her blood pressure at admission is 140/90 mm Hg. Fetal heart rate (FHR) tracing initially shows a baseline of 140 bpm with moderate variability and accelerations. No decelerations are noted. 

She requests medication for pain relief and is given morphine 10 mg IV x 1 dose. Shortly thereafter, the FHR tracing shows decreased variability and very few accelerations.

Which of the following is most likely responsible for the change in FHR tracing?

- Group B Strep positive
- IV morphine
- gestational hypertension
- IV penicillin
- 37 weeks’ gestational age
