The nurse is prioritizing the day's interventions. Which client should be the first to be taught about the hazards of straining when having a bowel movement?

The correct answer is B: 60-year-old recovering from a heart attack. This client should be the first to be taught about the hazards of straining during a bowel movement due to the increased risk of causing strain on the heart, which is still in the recovery phase. Straining during bowel movements can lead to increased intra-abdominal pressure and potentially worsen the heart condition. The other choices are not the priority for this teaching intervention. A: The 17-year-old with an ankle cast does not have a direct correlation to the hazards of straining during bowel movements. C: The 80-year-old admitted for an infected tooth would not be the priority as the dental issue does not impact the heart directly. D: The 28-year-old new mother of twins is not the priority for this teaching intervention as there are no indications that her situation requires immediate education on this topic.
