The mother of a 4-year-old client tells the pediatric nurse that the child's abdomen seems to be swollen. During further assessment, the mother tells the nurse that their child is eating well and that their activity level is unchanged. The nurse, suspecting the possibility of Wilms tumor, should avoid which action during the physical assessment?

A. Monitoring the temperature for fever is appropriate as part of a general assessment and could help identify signs of infection. B. Monitoring blood pressure is important because hypertension can be associated with Wilms tumor. C. Assessing the urine for hematuria is appropriate, as hematuria can be a symptom of Wilms tumor. D. Palpating the abdomen is contraindicated in suspected Wilms tumor cases because it could cause the tumor to rupture, potentially spreading cancerous cells. Therefore, palpating the abdomen should be avoided until further diagnostic procedures are performed.
