3.

A 40-year-old man is seen as a new patient to establish care. He has no complaints. His past medical history is negative. Baseline laboratory studies are significant for serum calcium of 11.5 mg/dL. Physical examination is normal. This patient's phosphate level would be:
- A.
  
  High
- B.
  
  Normal
- C.
  
  Low
4.

A 60-year-old man presents with complaints of fatigue and weakness for over 1 month. His past medical history is negative. His physical exam is significant for memory and cognitive defects. His labs are calcium 15.0 mg/dL and phosphate of 2.3 mg/dL. Predict the parathyroid hormone values if this patient's hyercalcemia were due to Primary hyperparathyroidism.

A 60-year-old man presents with complaints of fatigue and weakness for over 1 month. His past medical history is negative. His physical exam is significant for memory and cognitive defects. His labs are calcium 15.0 mg/dL and phosphate of 2.3 mg/dL. Predict the parathyroid hormone values if this patient's hypercalcemia were due to malignancy.
6.

A 60-year-old man presents with complaints of fatigue and weakness for over 1 month. His past medical history is negative. His physical exam is significant for memory and cognitive defects. His labs are calcium 15.0 mg/dL and phosphate of 2.3 mg/dL. Predict the parathyroid hormone values if this patient's hypercalcemia were due to vitamin D intoxication.

  Increased glomerular filtration
- B.
  
  Reduced absorption in the proximal tubule
- C.
  
  Increased secretion in the distal tubules
- D.
  
  Increased reabsorption in distal tubule
13.
