Correct Answer is C
Explanation
A. Threatening the child with a shot may create anxiety and fear, making cooperation even more challenging.
B. Hiding medication in food without the child's knowledge can lead to mistrust and may not be safe, as the child may not consume the entire dose.
C. Telling the child that the medication is candy is a strategy that may increase the likelihood of the child taking the medication willingly. However, it is important to ensure that the child understands the importance of taking the medication and that it is not actually candy.
D. Offering a choice of taking the medication with juice or water provides some control to the child, but it may not address the resistance to taking the medication itself. The child may still refuse regardless of the choice.
Correct Answer is D
Explanation
A. Rovsing's sign is a rebound tenderness felt in the right lower quadrant when the left lower quadrant is palpated. It may be positive in acute appendicitis but is not indicative of perforation.
B. A low-grade fever is common in acute appendicitis but may not necessarily indicate perforation.
C. A sudden decrease in abdominal pain may indicate perforation, but it is not a definitive sign.
Perforation can lead to a temporary relief of pain as the irritants spread throughout the peritoneum.
D. A flaccid abdomen (soft and lacking muscular tension) can be a sign of peritonitis, which may occur due to perforation of the appendix. It suggests irritation of the peritoneum and is a more significant concern than a localized infection.
