A nurse is planning care for an adolescent who has scoliosis and requires surgical intervention.

Which of the following behaviors by the adolescent should the nurse anticipate because it is the most common reaction?

Acute lead poisoning in toddlers can cause anorexia, as well as vomiting, abdominal pain, and constipation.
These symptoms can progress to seizures, coma, and even death if not treated promptly.
Choice A, increased urinary output, is not the correct answer because lead poisoning can cause a decrease in urinary output due to the effect of lead on the kidneys.
Choice C, diarrhea, is not the correct answer because lead poisoning is more likely to cause constipation than diarrhea.
Choice D, jaundice, is not the correct answer because jaundice is not a common finding in lead poisoning.
Jaundice is a yellowing of the skin and whites of the eyes caused by an excess of bilirubin in the blood, which is not directly related to lead poisoning.

Choice A rationale: Yellow nasal discharge in a toddler with acute nephrotic syndrome signifies a potential upper respiratory tract infection, which is critically important. Children with nephrotic syndrome are highly susceptible to infections due to significant urinary loss of immunoglobulins, leading to an immunocompromised state. Furthermore, corticosteroid treatments, often prescribed for nephrotic syndrome, suppress the immune system. An infection can precipitate a relapse of the syndrome, lead to severe complications like peritonitis or sepsis, and requires prompt evaluation and potentially antibiotic therapy to prevent life-threatening outcomes.

Choice B rationale: Poor appetite is a non-specific symptom in toddlers with nephrotic syndrome and does not typically indicate an immediate, life-threatening complication. It can be attributed to generalized malaise, abdominal discomfort due to ascites, or even side effects of medications such as corticosteroids. While important to monitor for nutritional status and overall well-being, it does not carry the same urgency as signs of infection, which can rapidly lead to severe health deterioration in an immunocompromised child.

Choice C rationale: Facial edema is a cardinal clinical manifestation of acute nephrotic syndrome, resulting from profound hypoalbuminemia. Reduced plasma oncotic pressure causes fluid to shift from the intravascular space into the interstitial space, leading to generalized edema, often prominently in the face. This finding is expected and indicates the disease process itself, rather than an acute, unexpected complication requiring immediate reporting, unless there is a sudden, significant worsening or associated respiratory compromise.

Choice D rationale: Irritability in a toddler can be a manifestation of general discomfort, illness, or even a side effect of corticosteroid therapy, which can cause mood disturbances and behavioral changes. While it warrants assessment to identify the underlying cause, irritability is a non-specific symptom and does not directly indicate an urgent, life-threatening complication of nephrotic syndrome requiring immediate medical intervention, unlike the signs of an acute infection in an immunocompromised child.
