A nurse is caring for a newborn who was born at 38 weeks of gestation, weighs 3 kg (6 lb 10 oz), and is receiving formula feedings every 3 hr.
The nurse should expect that at each feeding this newborn will consume how many mL?
30 mL
60 mL
90 mL
120 mL
The Correct Answer is C
90 mL. According to the CDC, babies who are only getting infant formula and no breast milk need about 2.5 ounces (75 mL) of formula per pound of body weight each day.
A newborn who weighs 3 kg (6 lb 10 oz) would need about 15 ounces (450 mL) of formula per day, divided into 8 to 12 feedings.
This means that at each feeding, the newborn would consume about 90 mL of formula.
Choice A is wrong because 30 mL is too little for a newborn who weighs 3 kg.
This would only provide about 10 ounces (300 mL) of formula per day, which is not enough for adequate growth and development.
Choice B is wrong because 60 mL is also too little for a newborn who weighs 3 kg.
This would only provide about 20 ounces (600 mL) of formula per day, which is still below the recommended amount.
Choice D is wrong because 120 mL is too much for a newborn who weighs 3 kg. This would provide about 40 ounces (1200 mL) of formula per day, which is more than the maximum amount of 32 ounces that most babies need before they start solids.
Overfeeding can cause problems such as spitting up, gas, and obesity.

Correct Answer is ["A","B"]
Explanation
The nurse should assess for proper latch-on technique and encourage skin-to-skin contact between mother and infant.
These actions promote successful breastfeeding and bonding.
Choice C is wrong because limiting feeding time to 10 min per breast can interfere with the infant’s intake of hindmilk, which is rich in fat and calories.The infant should be allowed to nurse until satisfied, which may take longer than 10 min per breast.
Choice D is wrong because instructing the client to offer both breasts at each feeding can lead to nipple soreness and engorgement.The client should offer one breast until it is emptied, then switch to the other breast if the infant is still hungry.
Choice E is wrong because advising the client to feed the infant every 2 to 3 hr can disrupt the infant’s natural feeding cues and rhythms.The client should feed the infant on demand, which may be more or less frequent than every 2 to 3 hr.
Correct Answer is D
Explanation
Growth and development evaluation should be done annually until adulthood, plotted on appropriate growth charts and compared with expected norms for age and sex, and used to identify any deviations from normal or expected patterns of growth and development.
Choice A is wrong because growth and development evaluation should not be done only annually, but also at specific ages recommended by the American Academy of Pediatrics (AAP), such as 9 months, 18 months, 24 months, and 30 months.
Choice B is wrong because growth and development evaluation should not only be plotted on appropriate growth charts and compared with expected norms for age and sex, but also include developmental milestones in playing, learning, speaking, behaving, and moving.
Choice C is wrong because growth and development evaluation should not only be used to identify any deviations from normal or expected patterns of growth and development, but also to monitor the child’s progress and provide early intervention if needed.
