Treatment of hypercalcemia includes, all, excepta) Gallium nitrateb) Plicamycin c) Etidronated) Rizol
**Core Concept**
Hypercalcemia is a condition characterized by elevated calcium levels in the blood, often resulting from excessive bone resorption, vitamin D intoxication, or malignancy. Treatment aims to reduce calcium levels and manage symptoms.
**Why the Correct Answer is Right**
Gallium nitrate (a) is a calcimimetic agent that inhibits osteoclast activity, reducing bone resorption. Plicamycin (b), also known as Mithramycin, inhibits bone resorption by binding to bone matrix. Etidronate (c) is a bisphosphonate that inhibits osteoclast activity, reducing bone resorption. These agents are all used to treat hypercalcemia.
**Why Each Wrong Option is Incorrect**
**Option A:** Rizol (d) is not a recognized treatment for hypercalcemia. It is possible that this option is a distractor or a non-standard abbreviation.
**Clinical Pearl / High-Yield Fact**
When treating hypercalcemia, it is essential to consider the underlying cause and choose the appropriate treatment. Bisphosphonates like etidronate are often the first line of treatment for malignancy-related hypercalcemia.
**Correct Answer: D. Rizol**
