A breastfed newborn has just been diagnosed with galactosemia. The therapeutic management for this newborn is to:
A. Stop breastfeeding
This is the correct answer because newborns and infants with galactosemia cannot metabolize galactose, a sugar found in milk and lactose-containing formulas, including breast milk. Galactose can build up in their blood and cause serious complications such as liver damage, cataracts, brain damage, and even death. Therefore, the therapeutic management for this newborn is to stop breastfeeding and switch to a soy or elemental formula that contains no galactose.
B. Add amino acids to the breast milk
This is incorrect because adding amino acids to breast milk will not prevent the accumulation of galactose in the newborn's blood. Amino acids are the building blocks of proteins, not sugars. Adding amino acids to breast milk will not change its galactose content or help the newborn metabolize it.
C. Substitute a lactose-containing formula for breast milk
This is incorrect because lactose is a disaccharide composed of glucose and galactose. Lactose-containing formulas will also expose the newborn to galactose, which they cannot break down. Lactose-containing formulas should be avoided in newborns and infants with galactosemia.
D. Give the appropriate enzyme along with breast milk.
Give the appropriate enzyme along with breast milk. This is incorrect because there is no enzyme therapy available for galactosemia. Galactosemia is caused by a genetic defect in one of the enzymes involved in the breakdown of galactose, such as galactose-1-phosphate uridylyltransferase (GALT), galactokinase (GALK), or uridine diphosphate galactose-4-epimerase (GALE). Giving an enzyme along with breast milk will not correct this defect or prevent the harmful effects of galactose accumulation.

Full Explanation
Choice A reason:
Stop breastfeeding. This is the correct answer because newborns and infants with galactosemia cannot metabolize galactose, a sugar found in milk and lactose-containing formulas, including breast milk. Galactose can build up in their blood and cause serious complications such as liver damage, cataracts, brain damage, and even death. Therefore, the therapeutic management for this newborn is to stop breastfeeding and switch to a soy or elemental formula that contains no galactose.
Choice B reason:
Add amino acids to the breast milk. This is incorrect because adding amino acids to breast milk will not prevent the accumulation of galactose in the newborn's blood. Amino acids are the building blocks of proteins, not sugars. Adding amino acids to breast milk will not change its galactose content or help the newborn metabolize it.
Choice C reason:
Substitute a lactose-containing formula for breast milk. This is incorrect because lactose is a disaccharide composed of glucose and galactose. Lactose-containing formulas will also expose the newborn to galactose, which they cannot break down. Lactose-containing formulas should be avoided in newborns and infants with galactosemia.
Choice D reason:
Give the appropriate enzyme along with breast milk. This is incorrect because there is no enzyme therapy available for galactosemia. Galactosemia is caused by a genetic defect in one of the enzymes involved in the breakdown of galactose, such as galactose-1-phosphate uridyltransferase (GALT), galactokinase (GALK), or uridine diphosphate galactose-4-epimerase (GALE).

A nurse is collecting data about reflexes from a newborn. Which of the following actions should the nurse take to elicit the newborn's Moro reflex?
A. Hold the newborn vertically, allowing one foot to touch the crib surface.
Holding the newborn vertically, allowing one foot to touch the crib surface, will elicit the stepping reflex, not the Moro reflex. The stepping reflex is when the newborn makes stepping movements when held upright with one foot touching a flat surface.
B. Turn the newborn's head quickly to one side.
Turning the newborn's head quickly to one side will elicit the tonic neck reflex, not the Moro reflex. The tonic neck reflex is when the newborn assumes a "fencing”. position, with the arm and leg extended on the side to which the head is turned and the opposite arm and leg flexed.
C. Perform a sharp hand clap near the infant.
Performing a sharp hand clap near the infant will elicit the Moro reflex, also known as the startle reflex. The Moro reflex is when the newborn responds to a sudden loss of support or a loud noise by extending and abducting the arms, spreading the fingers, and then bringing the arms together and crying.
D. Place a finger at the base of the newborn's toes.
Placing a finger at the base of the newborn's toes will elicit the Babinski reflex, not the Moro reflex. The Babinski reflex is when the newborn fans out the toes and dorsiflexes the big toe when the sole of the foot is stroked.

A nurse is updating the plan of care for a newborn who is undergoing phototherapy. Which of the following actions should the nurse include in the plan?
A. Monitor the newborn's blood glucose level hourly.
Monitoring the newborn's blood glucose level hourly is not necessary for a newborn undergoing phototherapy. Phototherapy does not affect blood glucose levels, and hourly monitoring would be too invasive and stressful for the newborn.
B. Apply lotion to the newborn's skin twice per day.
Applying lotion to the newborn's skin twice per day is not recommended for a newborn undergoing phototherapy. Lotion can interfere with the effectiveness of the phototherapy and increase the risk of skin irritation or infection.
C. Maintain the newborn in a prone position
Maintaining the newborn in a prone position is not advisable for a newborn undergoing phototherapy. The newborn should be positioned on alternate sides to expose as much skin surface as possible to the light source.
D. Encourage the newborn to breastfeed every 2 hr.
Encouraging the newborn to breastfeed every 2 hr is an appropriate action for a newborn undergoing phototherapy. Frequent feeding helps to promote hydration and the elimination of bilirubin from the body.

A nurse is reinforcing discharging teaching with a client who is 2 days postpartum. Which of the following statements should the nurse include in the teaching?
A. "If you give formula to your newborn, expect at least one stool every 3 days.".
This is incorrect because formula-fed newborns typically have one or more stools per day, not every 3 days. Stooling less frequently than once a day may indicate constipation.
B. "If you breastfeed your newborn, expect two to three stools per day.".
This is correct because breastfed newborns usually have two to three stools per day, which are soft and yellow. Breastfed babies may also have stools less frequently, even once every 10-14 days, as long as the stool is soft.
C. "You should feed your newborn formula every 2 hours.".
This is incorrect because newborns should be fed formula on demand, not on a strict schedule. The average feeding interval for formula-fed newborns is about 3 to 4 hours.
D. "You should breastfeed your newborn five to seven times each day.".
This is incorrect because newborns should be breastfed eight to 12 times per day, not five to seven times. Breastfeeding more frequently helps to establish milk supply and prevent engorgement. - Stanford Medicine.
