A parent of a child with acute renal failure (ARF) asks why peritoneal dialysis was chosen instead of hemodialysis. Which is the best response?

Correct Answer: C

Rationale: The controlled, gradual fluid removal with peritoneal dialysis is more suitable for pediatric patients.

Correct Answer: A

Rationale: The symptoms of fever, severe abdominal pain, and increasing confusion following a liver biopsy are indicative of a potential complication such as bleeding in the liver caused by the biopsy. Hepatic bleeding can lead to abdominal pain and can cause a change in the level of consciousness. These symptoms should prompt immediate medical attention to address the bleeding and prevent further complications. Perforation of the colon, an allergic reaction to contrast media, or normal post-procedural pain would not typically present with these specific symptoms in this context.

Correct Answer: D

Rationale: Facial erythema sparing the nasolabial folds is not a typical feature of JDM.

Correct Answer: D

Rationale: Traumatic retinoschisis is not typically associated with AHT-related retinal hemorrhages. Characteristics such as multiple layers, central location, and varying sizes are hallmarks of AHT-induced retinal damage.

Correct Answer: B

Rationale: Hepatitis A is transmitted via the fecal-oral route, commonly through contaminated food or water, and has only one serotype.
