Final answer:
To calculate the amount of fluid replacement required for a 20-kg dog that is 5% dehydrated, multiply the estimated blood volume by the degree of dehydration.
Step-by-step explanation:
To calculate the amount of fluid replacement required for a 20-kg dog that is 5% dehydrated, we need to consider the estimated blood volume of a dog and the degree of dehydration. Dogs are estimated to have approximately 80-90 mL of blood per kg body weight. So, for a 20-kg dog, the blood volume would be around 1600-1800 mL.
If the dog is 5% dehydrated, it means it is missing 5% of its total body water. To calculate the fluid replacement, we multiply the blood volume by the degree of dehydration: 1600-1800 mL x 5% = 80-90 mL.
Therefore, a 20-kg dog that is 5% dehydrated would require approximately 80-90 mL of fluid replacement.
