A school nurse is completing routine health evaluations for school-age children. Which of the following manifestation should alert the nurse to the possibility of pediculosis capitis?

A. Gross hematuria: Gross hematuria refers to visible blood in the urine, which can present as pink, red, or cola-colored urine. While hematuria can be associated with various kidney conditions, including Wilms' tumor, it is not a consistent or defining symptom of this specific tumor. Additionally, because the tumor is typically confined within the kidney and does not usually invade the urinary tract, gross hematuria might not always be present.

B. Dysuria: Dysuria is the medical term for painful or difficult urination. It is not a typical symptom of Wilms' tumor, as this tumor primarily affects the kidney and may not directly affect the urinary tract in a way that causes painful urination.

C. An abdominal mass: This is the correct answer. Wilms' tumor often presents as a palpable abdominal mass, which may be felt during physical examination. The mass is usually firm, non-tender, and confined to one side of the abdomen. Detection of an abdominal mass should prompt further diagnostic evaluation to confirm the diagnosis and plan appropriate treatment.

D. Nausea and vomiting: While some children with Wilms' tumor may experience nausea and vomiting, these symptoms are nonspecific and can be caused by various conditions. They are not considered characteristic or defining features of Wilms' tumor. The presence of nausea and vomiting would prompt further assessment to determine the underlying cause

A. "There are a few causes of this condition and they tell me my child has crossed eyes because of a muscle imbalance.": This statement demonstrates the mother's comprehension of the cause of strabismus, which can indeed result from a muscle imbalance affecting the alignment of the eyes. Understanding the cause is essential for the mother to grasp the rationale behind treatment interventions.

B. "I will have my child wear an eye patch over the good eye to help strengthen the weak eye.": Patching the stronger eye is a common treatment approach for strabismus to encourage the weaker eye to become stronger and improve alignment. The mother's statement indicates her awareness of this treatment modality.

C. "My child will outgrow this by the time he is 2 years old and be able to see just fine.": While some cases of strabismus may improve as a child grows, not all cases resolve spontaneously. This statement suggests the mother's belief in the possibility of spontaneous resolution, which may be accurate in some instances but not guaranteed for all cases of strabismus.

D. "If this eye patch does not work I know we will have to do surgery to correct my child's crossed eyes.": Surgery is indeed an option for correcting strabismus, especially if conservative measures like patching do not yield satisfactory results. The mother's understanding of this potential treatment escalation reflects her grasp of the condition's management plan.
