Which newborn is at the lowest risk for elevated unconjugated bilirubin levels?

The newborn with significant bruising from a face presentation.

The premature newborn.

The baby born at 41 weeks' gestation.

The newborn with O+ blood type, born to a mother with O- blood type.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

(Incorrect) The newborn with significant bruising from a face presentation is at an increased risk of elevated unconjugated bilirubin levels. Bruising can lead to the breakdown of red blood cells, increasing bilirubin production.

Choice B rationale:

(Incorrect) The premature newborn is at a higher risk of elevated unconjugated bilirubin levels. Premature infants often have an underdeveloped liver, which can lead to reduced bilirubin processing and clearance.

Choice C rationale:

(Correct) The baby born at 41 weeks' gestation is at the lowest risk for elevated unconjugated bilirubin levels. By this stage, the baby's liver is more mature, allowing for efficient processing and clearance of bilirubin.

Choice D rationale:

(Incorrect) The newborn with O+ blood type, born to a mother with O- blood type, is at an increased risk of elevated unconjugated bilirubin levels if the baby's blood type is Rh-positive and the mother's is Rh-negative. This situation can lead to Rh incompatibility and hemolytic disease of the newborn, causing higher bilirubin levels.

Correct Answer is B

Explanation

Choice A rationale:

A white blood cell count of 15,000 does not necessarily indicate a severe infection. In newborns, WBC counts are typically higher than in adults, and they gradually decrease over the first few days after birth. A value of 15,000 falls within the normal range for a newborn and is not indicative of a severe infection.

Choice B rationale:

A white blood cell count of 15,000 is considered a normal range for a newborn. Newborns have higher WBC counts as a natural response to the stress of birth and exposure to the outside environment. The immune system is still developing, and elevated WBC counts are normal during this period.

Choice C rationale:

Assuming there are no other indications of lab error, such as abnormal results in other tests, it would be premature to label the WBC count as a lab error. Additionally, healthcare professionals should always consider the overall clinical picture before assuming a lab error based on a single result.

Choice D rationale:

There is no immediate need to call the doctor based solely on the WBC count of 15,000. Medical decisions should be made in the context of the newborn's overall clinical condition, and a single lab result does not warrant an immediate call to the doctor.

A. Warm the bottle in the microwave. B. Store prepared bottles in the refrigerator. C. Discard unused formula in used bottle after 2 hours. D. Never prop a bottle. E. Formula is available in three forms.

Correct Answer is ["B","C","D"]

Explanation

Choice A: Warm the bottle in the microwave.

Rationale: Warming bottles in the microwave is not recommended. Microwaving can cause uneven heating, creating hot spots in the milk or formula that can burn the baby's mouth. Instead, bottles should be warmed by placing them in a container of warm water or using a bottle warmer.

Choice B: Store prepared bottles in the refrigerator.

Correct
Rationale: Prepared bottles of formula should be stored in the refrigerator to prevent bacterial growth. Formula should be used within 24 hours of preparation when properly stored in the refrigerator.

Choice C: Discard unused formula in used bottle after 2 hours.

Correct
Rationale: Any unused formula that has been in contact with the baby’s mouth should be discarded after 2 hours due to the risk of bacterial contamination. Bacteria from the baby's saliva can grow in the leftover formula.

Choice D: Never prop a bottle.

Correct
Rationale: Bottles should never be propped up and left in the baby’s mouth. This practice increases the risk of choking, ear infections, and tooth decay. Caregivers should always hold the bottle and the baby during feedings.

Choice E: Formula is available in three forms.

Correct
Rationale: Formula is available in three forms: powdered, concentrated liquid, and ready-to-feed. Parents should be informed of these options so they can choose the most convenient or appropriate form based on their needs.
