Question

A newborn weighs 3,874 grams at birth and 3,465 grams just prior to discharge from the hospital 2 days later. Knowing that newborns may lose 5-10% of their body weight in the first few days of life, what is the newborns current percent of weight loss?

Answer 1

The newborn's current percent of weight loss is approximately 10.57%.

Step-by-step explanation:

According to the information provided, newborns may lose 5-10% of their body weight in the first few days of life. To calculate the current percent of weight loss for this newborn, we need to find the difference between the birth weight (3,874 grams) and the weight prior to discharge (3,465 grams). Next, we divide this difference by the birth weight and multiply it by 100 to get the percentage.

Weight loss = (Birth weight - Weight prior to discharge) / Birth weight * 100

Weight loss = (3874 - 3465) / 3874 * 100 = 409 / 3874 * 100 ≈ 10.57%

Therefore, the newborn's current percent of weight loss is approximately 10.57%.

Answer 2

10.55%

Step-by-step explanation:

Given:

Initial weight of the new born baby = 3,874 grams

final weight of the baby = 3,465 grams

Now,

the current percentage of the weight loss will be calculated as:

Weight loss percentage =
`\frac{\textup{Loss in the weight}}{\textup{Initial weight of the baby}}*100`%

on substituting the respective values, we get

Weight loss percentage =
`((3874-3465))/(3874)*100`%

or

Weight loss percentage = 10.55%
