A nurse is caring for a toddler whose parent states that while bathing the child, she noticed a mass in his abdominal area and that his urine is a pink color. Which of the following actions is the nurse's priority?

Choice A reason: Hemorrhage is a potential issue for a child who has leukemia, as it is a condition that causes excessive bleeding, which can be caused by thrombocytopenia, coagulopathy, or bone marrow suppression. Leukemia can cause a low platelet count, which impairs the blood clotting process and increases the risk of bleeding from minor injuries, mucous membranes, or internal organs.

Choice B reason: Peripheral neuropathy is a potential issue for a child who has leukemia, as it is a condition that affects the nerves, which can be caused by chemotherapy, radiation, infection, or compression. Leukemia can cause nerve damage, which can result in numbness, tingling, pain, or weakness in the extremities, face, or trunk.

Choice C reason: Priapism is not a potential issue for a child who has leukemia, as it is a condition that causes a prolonged and painful erection of the penis, which can be caused by sickle cell disease, medication, trauma, or spinal cord injury. Leukemia does not affect the penis, but it can cause testicular pain, swelling, or masses due to leukemic infiltration.

Choice D reason: Tumor lysis syndrome is a potential issue for a child who has leukemia, as it is a condition that causes a rapid release of cellular contents into the bloodstream, which can be caused by chemotherapy, radiation, or spontaneous tumor breakdown. Tumor lysis syndrome can cause electrolyte imbalance, metabolic acidosis, renal failure, or cardiac arrhythmias.

Choice A reason: Ridged abdomen is not an expected finding for an infant who has pyloric stenosis, as it indicates abdominal rigidity or guarding, which can be a sign of peritonitis or bowel obstruction. Pyloric stenosis is a narrowing of the pyloric sphincter, which causes gastric outlet obstruction and delayed gastric emptying.

Choice B reason: Red currant jelly stools are not an expected finding for an infant who has pyloric stenosis, as they indicate blood and mucus in the stools, which can be a sign of intussusception or necrotizing enterocolitis. Pyloric stenosis does not affect the lower gastrointestinal tract, and the infant may have constipation or dehydration due to vomiting.

Choice C reason: Projectile vomiting is an expected finding for an infant who has pyloric stenosis, as it occurs after feeding due to the increased pressure in the stomach and the inability to pass food into the duodenum. Projectile vomiting can cause weight loss, dehydration, electrolyte imbalance, and metabolic alkalosis.

Choice D reason: Distended neck veins are not an expected finding for an infant who has pyloric stenosis, as they indicate increased central venous pressure, which can be a sign of heart failure or superior vena cava syndrome. Pyloric stenosis does not affect the cardiovascular system, and the infant may have sunken fontanels or poor skin turgor due to dehydration.
