Step-by-step explanation:
Given the information, we cannot definitively answer whether Rita's intake of caffeine is below the recommended upper limit for pregnant women, because the details of her consumption were not provided. However, it is generally advised that caffeine consumption during pregnancy should be moderated. Health guidelines typically recommend that pregnant women limit their caffeine intake due to potential risks, despite the fact that no conclusive evidence of negative effects has been established. Tolerance and even physical and mental addiction to caffeine can develop in individuals who consume it regularly, which can lead to increased consumption over time. High levels of caffeine in the bloodstream can have a range of negative health effects, as exemplified by the case study of a woman who developed health issues from excessive caffeine intake that mimicked symptoms of cardiovascular disease and diabetes.
