Final answer:
Following RUQ pain of appendicitis, the most common symptom is vomiting. Appendicitis usually starts with pain near the navel that shifts to the RLQ, and vomiting often occurs after the initial onset of pain. The cecum is the part of the large intestine to which the appendix is attached.
Step-by-step explanation:
Appendicitis is typically associated with abdominal pain, which often starts around the navel and then shifts to the right lower quadrant (RLQ) of the abdomen. The discomfort from appendicitis might be followed by other symptoms like nausea, vomiting, and anorexia (loss of appetite). These additional symptoms help healthcare professionals in diagnosing the condition.
When considering the options presented in the question, the symptom that follows the right upper quadrant (RUQ) abdominal pain of appendicitis is most typically (b) Vomiting. This is due to the fact that appendicitis can induce the gastrointestinal tract to become inflamed and irritated after the initial pain presentation. While constipation or diarrhea can sometimes be seen with appendicitis, vomiting after the onset of pain is more common and provides a clue to the diagnosis.
The part of the large intestine that attaches to the appendix is the (a) cecum. Knowing this helps in understanding where appendicitis pain and symptoms may present.
