A pregnant patient at 30 weeks gestation is complaining of severe heartburn. What should the nurse recommend?
- A. Lie down after meals to improve digestion.
- B. Drink a large amount of water after eating.
- C. Eat smaller meals more frequently and avoid lying down after meals.
- D. Take antacids regularly to relieve heartburn.
Correct Answer: C
Rationale: The correct answer is C: Eat smaller meals more frequently and avoid lying down after meals. This is the best recommendation for the pregnant patient experiencing severe heartburn at 30 weeks gestation. Eating smaller meals more frequently can help reduce the amount of stomach acid produced, thus decreasing the likelihood of heartburn. Avoiding lying down after meals can prevent stomach acid from flowing back into the esophagus, further reducing heartburn symptoms.
Rationale for why other choices are incorrect:
A: Lying down after meals can worsen heartburn by allowing stomach acid to flow back into the esophagus.
B: Drinking a large amount of water after eating may worsen heartburn by increasing stomach pressure and pushing stomach acid back up.
D: Taking antacids regularly may provide temporary relief but is not addressing the root cause of the heartburn and may not be safe for long-term use during pregnancy.
