A client has a serum calcium level of 12.0 mg/dL. The nurse suspects that the client is experiencing a pathophysiological process such as:
 
  1. osteomalacia.
  2. metastatic bone tumor.
  3. hypoparathyroidism.
  4. chronic renal disease.

Question 2

The recommended dietary allowance for calcium in the normal healthy adult is:
 
  1. 1,6002,000 mg per day.
  2. 1,0001,200 mg per day.
  3. 200600 mg per day.
  4. 2,4002,800 mg per day.

Answer to Question 1

Correct Answer: 2
Rationale 1: Osteomalacia is a deficiency of vitamin D, and it would contribute to lower-than-normal serum calcium levels.
Rationale 2: The bone destruction that occurs with metastatic bone tumors releases calcium into the bloodstream and elevates the serum calcium level.
Rationale 3: Hypoparathyroidism would result in lower-than-normal serum calcium levels.
Rationale 4: Chronic renal disease is associated with lower-than-normal levels of calcium.
Global Rationale: The bone destruction that occurs with metastatic bone tumors releases calcium into the bloodstream and elevates the serum calcium level. Osteomalacia is a deficiency of vitamin D, and it would contribute to lower-than-normal serum calcium levels. Hypoparathyroidism would result in lower-than-normal serum calcium levels. Chronic renal disease is associated with lower-than-normal levels of calcium.

Answer to Question 2

Correct Answer: 2
Rationale 1: This amount (1,6002,000 mg per day) is excessive.
Rationale 2: The normal healthy adult should consume 1,0001,200 mg of calcium per day.
Rationale 3: This amount (200600 mg per day) is insufficient to meet the needs of healthy adults.
Rationale 4: This amount (2,4002,800 mg per day) is excessive.
Global Rationale: The normal healthy adult should consume 1,0001,200 mg of calcium per day.
