Review Question - QID 213633

A 38-year-old female is brought in to the emergency room by her husband for fever and right upper quadrant pain. She states that 2 days ago she noticed a 7/10 sharp, stabbing pain that was intermittent. She took ibuprofen at that time, which provided some relief. However, the pain got progressively worse the next day and she developed a fever of 100.8°F (38.2°C). Her temperature is 101.3°F (38.5°C), blood pressure is 150/84mmHg, pulse is 104/min, and respirations are 15/min.
