The nurse reviews the client's serum calcium level and notes that the level is 7.9 mg/dL. The nurse understands that which condition would cause this serum calcium level?
Correct answer
D
Rationale
The correct answer is D: Excessive ingestion of vitamin D. Vitamin D promotes calcium absorption in the intestines, leading to increased serum calcium levels. Prolonged bed rest (A) can lead to bone demineralization, decreasing serum calcium. Too much butter consumption (B) does not directly affect serum calcium levels. Hyperparathyroidism (C) causes increased calcium release from bones, leading to high serum calcium. Excessive ingestion of vitamin D (D) directly increases serum calcium levels.
