A nurse is caring for a pregnant patient who is at 36 weeks gestation and reports that her baby has not moved as much as usual. What should the nurse instruct the patient to do first?
- A. Lie on her left side and drink a cold beverage to stimulate movement.
- B. Rest for a few hours and count fetal movements.
- C. Call the healthcare provider immediately to report the lack of movement.
- D. Monitor fetal movement over the next 24 hours and report if the pattern continues.
Correct Answer: A
Rationale: The correct answer is A: Lie on her left side and drink a cold beverage to stimulate movement. This is because changing positions can encourage fetal movement due to the change in gravity and blood flow. Additionally, the cold beverage may stimulate the baby to move. Option B suggests resting without actively trying to stimulate movement, which may delay necessary action. Option C advises immediate contact with the healthcare provider, which could be an overreaction at this stage. Option D delays action and may not address the immediate concern of decreased fetal movement.
