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 B
Explanation
Use an oral syringe to squirt the medication into the side of the mouth.
This is because an oral syringe allows the nurse to measure the exact dose of the medication and deliver it slowly and safely into the infant’s mouth, avoiding choking or aspiration.
The other choices are wrong for the following reasons:
• Choice A) Mixing the medication with formula in a bottle can alter the taste and effectiveness of the medication, and also make it difficult to ensure that the infant receives the full dose.
• Choice C) Placing the medication on a pacifier can cause the infant to spit out the pacifier or the medication, and also increase the risk of infection from contaminated pacifiers.
• Choice D) Dipping a cotton swab in the medication and rubbing it on the gums can irritate the oral mucosa and cause pain or bleeding, and also waste some of the medication on the swab.
Correct Answer is A
Explanation
Breasts are soft without engorgement or leakage.This indicates that lactation suppression has been successful and the woman is not experiencing any discomfort or risk of infection from milk accumulation.
Breasts are firm with mild tenderness or leakage is wrong because it suggests that lactation is still occurring and the woman may need to express some milk for comfort or use other non-pharmacological methods to suppress it.
Breasts are hard with moderate pain or leakage is wrong because it indicates that the woman is suffering from breast engorgement, which can lead to mastitis if not treated.The woman may need pharmacological intervention to suppress lactation and relieve pain.
Breasts are swollen with severe pain or leakage is wrong because it shows that the woman has developed mastitis, which is a bacterial infection of the breast tissue that requires antibiotics and analgesics.The woman may also need to drain the infected breast by expressing milk or using a pump.
Normal ranges for lactation suppression vary depending on the individual and the method used.Generally, lactation suppression can take from a few days to a few weeks.
