Which action should the nurse take when providing postoperative nursing care to a child after insertion of ventriculoperitone (VP) shunt?

A. Thrombocytopenia: Thrombocytopenia is a condition characterized by a low platelet count, and it is not a typical feature of iron-deficiency anemia.

B. Increased Total Iron-binding Capacity: In iron-deficiency anemia, the Total Iron-binding Capacity (TIBC) is typically increased as the body attempts to compensate for the low iron levels by increasing its capacity to bind and transport iron.

C. Decreased Folate Levels: While iron-deficiency anemia and folate-deficiency anemia are both forms of anemia, decreased folate levels are more characteristic of folate-deficiency anemia, which is a separate condition.

D. Microcytic Red Blood Cells.

Iron-deficiency anemia is characterized by a decrease in the body's iron stores, which in turn affects the production of hemoglobin and red blood cells. This results in the formation of microcytic (smaller than normal) red blood cells. These smaller red blood cells are a typical finding in iron-deficiency anemia.

A. Hypernatremia and Diabetes Insipidus.

The symptoms described, including dry mucous membranes, high urinary output, and seizures, are consistent with hypernatremia, which is an elevated level of sodium in the blood, and Diabetes Insipidus (DI).

Diabetes Insipidus is a condition where the body is unable to properly regulate water balance, leading to excessive thirst and urination. In the presence of DI, water loss is excessive, leading to dehydration, increased sodium levels, and potentially seizures.

B. Hyponatremia and Diabetes Insipidus: This option doesn't align with the symptom of hypernatremia (elevated sodium levels) but suggests low sodium levels (hyponatremia), which would have different symptoms.

C. Hyponatremia and Syndrome of Inappropriate Antidiuretic Hormone (SIADH): This option also suggests low sodium levels (hyponatremia) and a different condition (SIADH) characterized by water retention and dilution of the blood, which is not consistent with the described symptoms.

D. Hypernatremia and Syndrome of Inappropriate Antidiuretic Hormone (SIADH): This option suggests high sodium levels (hypernatremia) but includes SIADH, which would not result in high urinary output. SIADH is characterized by excessive retention of water, leading to low urinary output and concentrated urine.
