Answer :
The trend of Gwen's temperature from the time she arrived in the emergency room until 12 hours later was from 99.4 to 101.2 degrees F, as per option A.
Therefore, the correct option is A).
1. To determine the trend of Gwen's temperature, we need to compare her initial temperature upon arrival with her temperature 12 hours later.
2. The difference between the initial and final temperatures will indicate the trend of her temperature over the specified period.
3. Given that the initial temperature was 99.4 degrees F and the temperature 12 hours later was 101.2 degrees F, we observe an increase in temperature over time, indicating a rising trend.
4. Therefore, option A, which states the temperature range from 99.4 to 101.2 degrees F, aligns with the observed trend of Gwen's temperature increasing during the specified period.
Thus, it accurately reflects the increasing trend observed in Gwen's temperature over the specified period, as indicated by option A.
Therefore, the correct option is A).
