Final answer:
The expected weight gain for an infant after 2 weeks is an average of about 392 g, gaining roughly 28 g per day. Infants usually double their birth weight by six months, not two weeks. The closest correct answer is that an infant should maintain and slightly exceed the birth weight after two weeks.
Step-by-step explanation:
The question asks how much weight an infant should gain after 2 weeks of life. According to health and growth standards, after the initial weight loss right after birth, an infant gains an average of about 28 g (1 oz) per day during the first two months. Therefore, over a period of 2 weeks, the expected weight gain would be approximately 392 g (28 g/day × 14 days), which is not close to even doubling the birth weight. Infants usually double their birth weight by six months and triple it by 12 months.
The correct answer is:
d) Maintain the birth weight
However, this is not strictly accurate as infants typically regain their birth weight within the first two weeks and might exceed it slightly by the end of the second week. The answer choice that assumed maintaining the birth weight would imply no weight gain, which contradicts the average daily weight gain that is expected. Therefore, none of the options perfectly match the expected weight gain, but the closest would be to expect the infant to regain and slightly exceed the original birth weight after two weeks.
