A 4-year-old child diagnosed with iron deficiency anemia is prescribed oral ferrous sulfate. The child's parents report difficulty administering the medication due to gastrointestinal side effects and poor adherence. Which nursing action is most appropriate to enhance the effectiveness of treatment and minimize complications?

A. Massive proteinuria and generalized edema is correct because nephrotic syndrome results from increased permeability of the glomerular membrane. This allows large amounts of protein, especially albumin, to be lost in the urine (proteinuria). The loss of albumin leads to hypoalbuminemia, which reduces plasma oncotic pressure. As a result, fluid shifts from the intravascular space into the interstitial tissues, causing generalized edema. Edema is often most noticeable around the eyes (periorbital edema), abdomen (ascites), and lower extremities. Additional associated findings may include hyperlipidemia and lipiduria due to the liver’s increased production of lipids in response to protein loss.

B. Hematuria and flank pain is incorrect because these findings are more characteristic of nephritic syndromes such as acute poststreptococcal glomerulonephritis. Nephrotic syndrome typically does not present with significant hematuria or flank pain; instead, protein loss and edema are the dominant features.

C. Polyuria and polydipsia is incorrect because these symptoms are commonly associated with endocrine disorders such as diabetes mellitus or diabetes insipidus. In nephrotic syndrome, urine output may actually decrease due to fluid shifting into tissues and activation of fluid-retaining mechanisms.

D. Hyperactive reflexes and muscle spasms is incorrect because these signs are indicative of electrolyte imbalances such as hypocalcemia. While electrolyte disturbances can occur in kidney disorders, they are not defining or expected hallmark findings of nephrotic syndrome.

A. Encouraging the child to drink fluids to stay hydrated is incorrect because while hydration is important, the priority is identifying and managing potential increased intracranial pressure (ICP). Giving fluids before assessing neurological status may delay recognition of a serious complication.

B. Positioning the child in a flat supine position is incorrect because a flat supine position can actually increase ICP. Postoperative positioning for brain surgery typically involves head elevation (30 degrees) to promote venous drainage and reduce ICP, unless contraindicated.

C. Administering an antiemetic to control vomiting is incorrect as controlling vomiting is secondary. Vomiting can be a sign of increased ICP, so addressing the underlying cause is more important than treating symptoms alone.

D. Assessing the child's neurological status and checking for signs of increased intracranial pressure is correct. Vomiting and headache after brain surgery are red flags for increased ICP, which can lead to life-threatening complications such as brain herniation. Priority nursing actions include frequent neurological assessments (level of consciousness, pupil size and reactivity, motor function), monitoring vital signs for changes in blood pressure, pulse, and respiration (Cushing’s triad), notifying the healthcare provider immediately if ICP is suspected, and implementing interventions to reduce ICP, such as proper positioning, oxygenation, and minimizing stimuli.
