A nurse is reviewing laboratory results for a newborn who is breastfed.
Which of the following findings indicates adequate nutrition?
Hemoglobin level of 11 g/dL
Serum calcium level of 8 mg/dL
Serum bilirubin level of 15 mg/dL
Serum sodium level of 130 mEq/L
The Correct Answer is A
Hemoglobin level of 11 g/dL. This is within the normal range for a newborn, which is 13.4-19.9 g/dL for the first month.
Hemoglobin is the oxygen-carrying protein in red blood cells.
Choice B is wrong because serum calcium level of 8 mg/dL is below the normal range for a newborn, which is 8.5-10.6 mg/dL for the first month.
Calcium is important for bone health and muscle function.
Choice C is wrong because serum bilirubin level of 15 mg/dL is above the normal range for a newborn, which is less than 12 mg/dL for the first week.
Bilirubin is a waste product from the breakdown of red blood cells.
High levels can cause jaundice, a yellowing of the skin and eyes.
Choice D is wrong because serum sodium level of 130 mEq/L is below the normal range for a newborn, which is 135-145 mEq/L.
Sodium is an electrolyte that helps regulate fluid balance and nerve impulses.

Correct Answer is B
Explanation
“I will give my baby soft finger foods that he can pick up and eat by himself.” This statement indicates an understanding of the teaching because it shows that the mother knows how to provide appropriate complementary foods for her infant who is eight months old.Complementary feeding, also known as weaning, mixed feeding or introduction of solid foods, should begin for infants by six months of age (26 weeks) but not before 17 weeks.Breast milk or infant formula should continue during the complementary feeding period with amounts gradually reduced as the variety of foods increases.WHO and UNICEF recommend that infants start receiving complementary foods at 6 months of age in addition to breast milk.Initially, they should receive complementary foods 2–3 times a day between 6–8 months and increase to 3–4 times daily between 9–11 months and 12–24 months of age.Complementary foods should be nutritionally adequate, safe, and properly fed.
Choice A is wrong because pureed foods are not suitable for an eight-month-old infant who can handle more textured foods.
Pureed foods are recommended for infants who are just starting complementary feeding at around six
Correct Answer is B
Explanation
Cover the newborn’s eyes with a mask or shield.This is because phototherapy can cause eye damage and the mask or shield protects the newborn’s eyes from the light.
Some additional explanations are:
• Choice A is wrong because increasing fluid intake by 25% to prevent dehydration is not necessary for a newborn receiving phototherapy.The newborn should be fed on demand or according to a regular schedule and monitored for signs of dehydration such as poor skin turgor, dry mucous membranes, sunken fontanels, and decreased urine output.
• Choice C is wrong because applying lotion or oil to the newborn’s skin to prevent drying is not recommended for a newborn receiving phototherapy.Lotion or oil can increase the absorption of light and cause skin burns.
• Choice D is wrong because turning off the phototherapy lights during feedings is not advised for a newborn receiving phototherapy.The lights should be on continuously to maximize the effectiveness of the treatment and reduce the duration of exposure.
