Tumor lysis syndrome is a common complication during treatment of pediatric malignancies. Which malignancy is more likely to manifest such complication?

Correct Answer: D

Rationale: Burkitt lymphoma is highly proliferative and sensitive to chemotherapy, leading to rapid cell death and tumor lysis syndrome.

Correct Answer: C

Rationale: Chronic respiratory acidosis is a condition where there is an excess of carbon dioxide (CO2) in the blood due to inadequate exhalation of CO2. This typically occurs as a result of hypoventilation, which is characterized by breathing at an abnormally slow rate or shallow depth. In patients with long-standing lung disease, the ability to effectively exchange gases in the lungs is compromised, leading to a buildup of CO2 in the bloodstream and subsequent respiratory acidosis. Hyperventilation, on the other hand, would result in a decrease in CO2 levels in the blood, while the loss of acid or base by the kidneys is related to metabolic acidosis or alkalosis, not respiratory acidosis. Therefore, in this case, the primary problem causing chronic respiratory acidosis is hypoventilation.

Correct Answer: B

Rationale: Spastic cerebral palsy is the most common type.

Correct Answer: C

Rationale: The erythrocyte sedimentation rate (ESR) is an important diagnostic test that can help identify inflammation in the body, including inflammation in the heart. Elevated ESR levels may indicate the presence of an underlying condition that could potentially lead to cardiac complications if left untreated. Regular monitoring of ESR levels can help in the early detection and prevention of cardiac issues. The other options (A. Chest x-ray examination, B. Throat culture, and D. White blood cell count) are not specific diagnostic tests for assessing cardiac complications.

Correct Answer: C

Rationale: Swelling and discoloration after hydrocele repair are typically normal postoperative findings and do not require immediate intervention unless excessive or worsening.
