The nurse explains to the parents of a 2-day-old newborn that decreased life span of neonatal red blood cells has contributed to which complication?
Hyperbilirubinemia.
Respiratory distress syndrome.
Polycythemia.
Transient tachypnea.
The Correct Answer is A
The correct answer is: a. Hyperbilirubinemia.
Choice A: Hyperbilirubinemia
Reason: Hyperbilirubinemia in newborns is often caused by the increased breakdown of red blood cells, which have a shorter lifespan in neonates. This breakdown produces bilirubin, a yellow pigment that can accumulate in the blood, leading to jaundice. The liver of a newborn is not fully mature and may not be able to process and excrete bilirubin efficiently, resulting in hyperbilirubinemia.
Choice B: Respiratory Distress Syndrome
Reason: Respiratory Distress Syndrome (RDS) is primarily caused by a deficiency of surfactant in the lungs, which is more common in premature infants. It is not directly related to the lifespan of red blood cells. Symptoms include rapid, shallow breathing and a bluish color due to lack of oxygen.
Choice C: Polycythemia
Reason: Polycythemia is characterized by an abnormally high concentration of red blood cells. It is often due to factors like delayed cord clamping or maternal diabetes, rather than the decreased lifespan of red blood cells. Polycythemia can lead to increased blood viscosity and complications such as sluggish blood flow.
Choice D: Transient Tachypnea
Reason: Transient Tachypnea of the Newborn (TTN) is a respiratory condition caused by delayed clearance of fetal lung fluid. It typically resolves within a few days and is not related to the lifespan of red blood cells. Symptoms include rapid breathing and grunting.

Correct Answer is A
Explanation
Choice A reason:
Choice A is the correct answer because the number of wet diapers a newborn has per day is a reliable indicator of effective breastfeeding. When a baby is breastfeeding well and getting enough milk, they will have an adequate number of wet diapers, typically at least six to eight per day. The frequent wet diapers indicate that the baby is adequately hydrated, and their body is eliminating waste products as expected.
Choice B reason:
Choice B, having at least one breast milk stool every 24 hours, is not the most reliable indicator of effective breastfeeding, although it is an important consideration. The frequency of bowel movements can vary among breastfed infants, and some babies may have several bowel movements a day, while others may have fewer, even skipping a day. The number of wet diapers is a more consistent measure of sufficient milk intake.
Choice C reason:
Choice C, sleeping for 6 hours at a time between feedings, is not an accurate indicator of effective breastfeeding in a 4-day-old newborn. Newborns typically feed frequently, at least 8-12 times in 24 hours, and they may not sleep for extended periods between feedings at this age. Frequent feeding is essential for establishing a good milk supply and ensuring the baby receives enough nutrients.
Choice D reason:
Choice D, gaining 1 to 2 ounces per week, is also not the most reliable indicator of effective breastfeeding in the early days after birth. Weight gain can vary significantly in newborns, and a 4-day-old baby might not show the expected 1 to 2 ounces per week gain yet. Moreover, weight gain can be affected by factors other than breastfeeding, such as birth weight, initial fluid loss, and individual growth patterns.
Correct Answer is B
Explanation
Choice A reason:
Inspecting if the urethral opening appears circular. This is a correct action for the nurse to do, as it helps to identify any abnormalities in the urethral opening, such as hypospadias or epispadias, which are congenital defects where the opening is located on the underside or the top of the penis, respectively. • Choice B reason:
Retracting the foreskin over the glans to assess for secretions. This is an incorrect action for the nurse to avoid, as it can cause pain, bleeding, and infection in the newborn. The foreskin is usually adhered to the glans in newborns and should not be forcibly retracted. It will gradually loosen over time and can be retracted by the child himself when he is older. •
Choice C reason:
Palpating if testes are descended into the scrotal sac. This is a correct action for the nurse to do, as it helps to detect any undescended testes, which are more common in preterm infants and can increase the risk of infertility and testicular cancer later in life. • Choice D reason:
Inspecting the genital area for irritated skin. This is a correct action for the nurse to do, as it helps to identify any signs of diaper rash, fungal infection, or allergic reaction in the newborn's skin.
