A child arrives at the emergency room experiencing nausea, vomiting, headache and photophobia and is diagnosed with bacterial meningitis. Other findings include a decrease in urine output, hyponatremia and water intoxication. Which pituitary gland disorder would be considered?

A. This is a form of regression is incorrect because regression involves reverting to behaviors from an earlier developmental stage (e.g., bedwetting or thumb-sucking) often triggered by stress or illness. Having an imaginary friend is a normal developmental behavior in preschoolers and is not considered regression.

B. Preschool-aged children (ages 3–6) are in Piaget’s preoperational stage and Erikson’s initiative vs. guilt stage, during which imaginative and symbolic play is typical. Imaginary friends are a common expression of magical thinking and creativity, allowing children to explore social roles, practice problem-solving, and express emotions in a safe, controlled way. This behavior is developmentally appropriate and usually does not indicate a psychological problem.

C. Inclusion of imaginary friends may indicate lack of parental attention is incorrect because the presence of imaginary friends is not a sign of neglect or lack of attention. It is a normal aspect of imaginative play, even in children who receive adequate parental interaction and support.

D. She needs to seek psychiatric help for her daughter is incorrect because the presence of an imaginary friend in a preschooler is not pathological. Unless accompanied by other concerning behaviors (e.g., social withdrawal, aggression, developmental regression), it is considered a normal developmental phenomenon.

A. This is ineffective. Waiting until nausea occurs reduces the effectiveness of antiemetics because CINV is often more difficult to control once established. Nonpharmacologic methods (e.g., relaxation, acupressure) can help, but they are usually adjuncts, not first-line preventive therapy.

B. PRN administration is reactive rather than proactive. Chemotherapy often induces anticipatory or acute nausea, which may not respond fully to medication given after symptoms begin. This approach increases discomfort and the risk of dehydration and electrolyte imbalance.

C. Prophylactic administration ensures that the medication is at therapeutic levels in the bloodstream before chemotherapy begins, preventing or reducing the severity of nausea and vomiting. This approach is supported by clinical guidelines and improves patient comfort and treatment adherence.

D. Delaying scheduled dosing until nausea starts is less effective. Nausea prevention is more effective than treatment after it occurs. Scheduled dosing should begin before or at the start of chemotherapy, not after symptoms develop.
