(Weight = Height – 100) denotes which formula/ index-
**Core Concept**
The question is referring to a formula used to calculate the ideal body weight (IBW) in adults. This formula is essential in clinical settings for determining appropriate doses of medications, especially in the context of anesthesia, surgery, and critical care.
**Why the Correct Answer is Right**
The formula (Weight = Height - 100) is a simplified version of the Devine formula, which is used to estimate the ideal body weight. This formula takes into account the patient's height and age to calculate the ideal weight, which is then used to calculate the ideal body surface area (IBSA). The Devine formula is widely used in clinical practice, particularly in the United States and Canada.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a recognized formula for calculating ideal body weight.
**Option B:** This option is not a valid formula for calculating ideal body weight.
**Option C:** This option is not a recognized formula for calculating ideal body weight.
**Clinical Pearl / High-Yield Fact**
The Devine formula is a useful tool for estimating ideal body weight, especially in patients with obesity or other conditions where body weight may not accurately reflect body composition. However, it's essential to note that this formula is not suitable for all populations, and other formulas may be more accurate in certain situations.
**Correct Answer: C. Body Mass Index (BMI).**
