## **Core Concept**
The patient's symptoms of amenorrhea, infertility, and galactorrhea suggest hyperprolactinemia, a condition characterized by elevated levels of prolactin in the blood. This condition can disrupt normal menstrual function and fertility. The treatment often involves medications that reduce prolactin levels.

## **Why the Correct Answer is Right**
The correct answer, **C. Cabergoline**, is a dopamine agonist that is commonly used to treat hyperprolactinemia. It works by stimulating dopamine receptors in the pituitary gland, which inhibits the secretion of prolactin. Cabergoline is preferred over other dopamine agonists like bromocriptine due to its longer half-life, which allows for less frequent dosing and better patient compliance. It is effective in restoring ovulation and menstruation in women with hyperprolactinemia.

## **Why Each Wrong Option is Incorrect**
- **Option A:** is incorrect because, although it could be a treatment for hyperprolactinemia, it is not specified and less commonly referenced in this context compared to Cabergoline or Bromocriptine.
- **Option B:** is incorrect because, while Clomiphene citrate is used to induce ovulation, it does not directly treat hyperprolactinemia and would not be the first-line treatment for a patient with elevated prolactin levels.
- **Option D:** is incorrect because, without a specified drug, it's hard to directly refute, but given the context, Cabergoline is a more direct and commonly used treatment for hyperprolactinemia.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that before starting dopamine agonists like Cabergoline, patients should be carefully questioned about a history of mental health problems, as these drugs can potentially exacerbate or trigger psychiatric conditions such as depression, anxiety, or psychosis.

## **Correct Answer:** C. Cabergoline.
