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

Answer and Explanation

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.

A. Breast milk does not contain enough vitamin D for bone health B. Breast milk interferes with vitamin D absorption from sunlight C. Breast milk increases vitamin D excretion in urine D. Breast milk inhibits vitamin D synthesis in the liver

Correct Answer is A

Explanation

Breast milk does not contain enough vitamin D for bone health.Vitamin D is needed to support healthy bone development and to prevent rickets, a condition that causes weak or deformed bones.Breast milk alone does not provide infants with an adequate amount of vitamin D.The Dietary Guidelines for Americans and American Academy of Pediatrics recommend breastfed and partially breastfed infants be supplemented with 400 IU per day of vitamin D beginning in the first few days of life.

Choice B is wrong because breast milk does not interfere with vitamin D absorption from sunlight.However, reducing sun exposure is important for preventing skin cancer, and other factors such as clothing, air pollution, and skin type can also decrease the amount of vitamin D a person can make from sunlight.

Choice C is wrong because breast milk does not increase vitamin D excretion in urine.

Vitamin D is a fat-soluble vitamin that is stored in the body and not easily lost in urine.

Choice D is wrong because breast milk does not inhibit vitamin D synthesis in the liver.Vitamin D is synthesized in the skin from exposure to sunlight, and then activated in the liver and kidneys to its active form.

Breast milk does not affect this process.
