Which food choice is most appropriate for a child who had a tonsillectomy and is now awake and tolerating fluids?

a) The infant having a higher basal metabolic rate: Basal metabolic rate doesn't directly impact urine specific gravity.

b) The infant’s kidneys being less able to concentrate urine: In fact, infants have immature kidneys that are less efficient at concentrating urine, but this is not the primary reason for lower specific gravity.

c) The infant having a greater percentage of body weight in water: Infants have a higher percentage of body weight in water, leading to more dilute urine.

d) The infant having a greater body surface area: While body surface area influences some aspects of renal function, it's not the main factor affecting urine specific gravity in infants.

a) Weight should triple by 6 months of age: Typically, a newborn's birth weight should double by around 4 to 6 months of age and triple by approximately 12 months (1 year).

b) Weight should double by 4 months of age: Doubling the birth weight by 4 months is too rapid for healthy growth.

c) Weight should double by 1 year of age: Weight doubling usually occurs by 6 months of age. By 1 year of age, a baby's weight is expected to be about three times their birth weight.

d) Weight should triple by 1 year of age: By the end of the first year, a baby’s weight typically triples from their birth weight, which is a standard growth milestone.
