Question

the nurse reviews a clients laboratory report and notes that the clients serum phosphorus (phosphate) level is 1.8 mg/dl (0.45 mmol/l). which condition most likely caused this serum phosphorus level?
answer options
1 malnutrition
2 renal insufficiency
3 hypoparathyroidism
4 tumor lysis syndrome

Explanation:

Malnutrition can lead to low serum phosphorus levels as the body may not be getting adequate nutrients. Renal insufficiency usually causes high phosphorus levels (as kidneys can't excrete it well). Hypoparathyroidism leads to high phosphorus (due to decreased parathyroid hormone which regulates phosphorus). Tumor lysis syndrome causes high phosphorus (from cell breakdown).

Answer:

1. Malnutrition
