The nurse is assessing a 12-month-old healthy infant who weighed 7 pounds at birth. The nurse should expect the infant to now weigh approximately:

21pounds

14 pounds

25 pounds

10 pounds

Answer and Explanation

The Correct Answer is A

A. 21 pounds: This is the correct answer. The general guideline is that infants tend to triple their birth weight by the age of 12 months. If the infant weighed 7 pounds at birth, tripling that weight would be 21 pounds.

B. 14 pounds: This weight would not be consistent with the expected weight gain of a healthy infant by 12 months. It's too low based on the tripling guideline.

C. 25 pounds: This weight would be higher than expected based on the tripling guideline. It's not a typical weight for a healthy 12-month-old who had a birth weight of 7 pounds.

D. 10 pounds: This weight would be lower than the expected weight gain. A 12-month-old who started at 7 pounds should have gained more weight by this age.

Correct Answer is ["46"]

Explanation

To provide adequate hydration for a toddler with dehydration, the nurse needs to calculate the daily fluid requirements based on the child's weight and then divide it by 24 hours to get the hourly rate.

For a 12 kg toddler, the daily fluid requirement is 1000 ml for the first 10 kg plus 50 ml for each additional kg, which equals 1100 ml.

Therefore, the hourly rate is 1100 ml / 24 hours, which is about 46 ml.

The nurse would set the pump at 46 ml per hour.

A. She returns the blocks to the same spot on the table. B. She looks for the toy the parents hide under the blanket. C. She bangs two cubes held in her hands. D. She recognizes that a ball of clay is the same when flattened out.

Correct Answer is B

Explanation

A. She returns the blocks to the same spot on the table.

This behavior is more related to a sense of order or routine rather than object permanence. It doesn't directly demonstrate understanding object permanence.

B. She looks for the toy the parents hide under the blanket.

This behavior is consistent with the concept of object permanence. If the child searches for a hidden toy, it indicates an understanding that the object still exists even when out of sight.

C. She bangs two cubes held in her hands.

Banging cubes is not directly related to object permanence. It might demonstrate exploration or cause-and-effect understanding, but it doesn't specifically indicate object permanence.

D. She recognizes that a ball of clay is the same when flattened out.

This behavior demonstrates an understanding of conservation, which is different from object permanence. Conservation involves recognizing that the quantity of a substance remains the same despite changes in shape.
