**Core Concept**
In snake envenomation, antivenom administration is a crucial step in managing the condition. Antivenom is a type of hyperimmune globulin that contains antibodies specific to the venom of the snake. The administration of antivenom is guided by the principle of neutralizing the venom and preventing further envenoming.

**Why the Correct Answer is Right**
The correct dose of antivenom for snake envenomation is typically a dose of 1 vial (or 10 mL) per 10 kg of body weight. This dose is based on the amount of venom that the patient has been exposed to and the severity of the envenoming. The antivenom works by binding to the venom and preventing it from interacting with the body's tissues, thereby reducing the severity of the symptoms and preventing further damage.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the dose of antivenom is not based on the patient's age or sex, but rather on their weight and the severity of the envenoming.
**Option B:** This option is incorrect because the dose of antivenom is not based on the type of snake that envenomed the patient, but rather on the amount of venom that was administered.
**Option C:** This option is incorrect because the dose of antivenom is not based on the patient's vital signs, such as heart rate or blood pressure, but rather on their weight and the severity of the envenoming.

**Clinical Pearl / High-Yield Fact**
It is essential to note that antivenom should be administered as soon as possible after envenoming, as delay in treatment can lead to severe consequences.

**Correct Answer:** C. 10 mL per 10 kg body weight.
