Correct Answer: A

Rationale: Right lower quadrant pain is a classic symptom of appendicitis. The appendix is typically located in the right lower quadrant of the abdomen, so pain in this area is commonly associated with appendicitis. Choices B, C, and D are incorrect because left lower quadrant pain, rebound tenderness, and epigastric pain are not typical manifestations of appendicitis. Left lower quadrant pain is not associated with appendicitis since the appendix is situated in the right lower quadrant. Rebound tenderness is more commonly linked with peritonitis rather than appendicitis. Epigastric pain is not a typical presentation of appendicitis as the pain is usually localized to the right lower quadrant.

Correct Answer: A

Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.

Correct Answer: B

Rationale: In a situation where a limb is protruding from the vagina during active labor, the correct management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord and improves oxygenation to the fetus. Administering oxygen is important to ensure adequate oxygen supply to both the mother and the baby. Providing transport is necessary for prompt transfer to a medical facility for further management. Applying gentle traction to the protruding limb is not recommended as it can cause harm to the baby and should be avoided. Giving 100% oxygen and attempting to manipulate the protruding limb is not the correct approach and can potentially lead to further complications.

Correct Answer: C

Rationale: The correct answer is C. Moving a child to a regular bed by the age of three can increase the risk of falls as young toddlers may not have the motor skills to safely navigate a larger bed. This indicates a need for more teaching on safety measures. Choices A, B, and D are all appropriate safety measures that can help prevent accidents and injuries in young children. Keeping medications in a medicine cabinet, having secured gates at entrances to staircases, and choosing shoes that fasten with Velcro instead of laces are all good practices to ensure a safe environment for toddlers.

Correct Answer: A

Rationale: Seizures in children most often result from an abrupt rise in body temperature, leading to febrile seizures. Febrile seizures are common in young children and are typically triggered by a rapid increase in body temperature, often due to infections or other causes. An inflammatory process in the brain (Choice B) is less common as a cause of seizures in children and is usually associated with specific conditions like encephalitis or meningitis. While a temperature greater than 102°F (Choice C) may trigger a febrile seizure, it is the abrupt rise in temperature that is the primary cause. Choice D, a life-threatening infection, is a broad and less specific cause compared to the direct trigger of an abrupt rise in body temperature.
