Q: A patient presents with a burn that affects the epidermis and part of the dermis, causing blisters and pain. According to the rule of nines, which formula would you use to estimate the percentage of body surface area affected?

$$\text{Total Burn Area} = \text{Sum of affected regions percentages}$$

Q: Which equation best represents the relationship between stress and bone remodeling?

$$\text{Bone Remodeling Rate} = k \times \text{Mechanical Stress}$$

Q: Which formula would you use to calculate the percentage of organic material in bone if you know the total mass and the mass of organic components?

$$\text{Percentage Organic} = \frac{\text{Mass of organic components}}{\text{Total bone mass}} \times 100\%$$

Q: Which equation would you use to determine the rate of tissue repair if you know the number of new cells formed per day and the total area to be repaired?

$$\text{Repair Rate} = \frac{\text{Number of new cells per day}}{\text{Total area to be repaired}}$$
