Multiple choice

What is the primary cause of neonatal jaundice?

  1. Increased red blood cell production

  2. Decreased red blood cell destruction

  3. Impaired bilirubin conjugation

  4. Obstruction of bile flow
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In neonates, the immature liver is unable to efficiently conjugate bilirubin, leading to its accumulation in the blood.

  2. Low birth weight

  3. Cephalohematoma

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Prematurity, low birth weight, and cephalohematoma are all risk factors for developing severe neonatal jaundice.

Multiple choice

  1. Physiologic jaundice

  2. Breast milk jaundice

  3. Pathologic jaundice

  4. Cholestatic jaundice
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Physiologic jaundice is the most common type of neonatal jaundice, affecting up to 80% of newborns.

Multiple choice

When is phototherapy indicated for the treatment of neonatal jaundice?

  1. Total serum bilirubin level >15 mg/dL

  2. Direct serum bilirubin level >2 mg/dL

  3. Jaundice persisting beyond 2 weeks of life

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multiple choice

What is the role of breastfeeding in the management of neonatal jaundice?

  1. Breastfeeding should be discontinued if the infant has jaundice

  2. Breastfeeding should be encouraged as it helps to prevent jaundice

  3. Breastfeeding should be limited to 8-10 feedings per day

  4. Breastfeeding should be supplemented with formula if the infant has jaundice
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Breastfeeding should be encouraged as it helps to prevent jaundice by promoting the passage of bilirubin from the infant's gut.

Multiple choice

What is the recommended management of breast milk jaundice?

  1. Discontinue breastfeeding for 24-48 hours

  2. Supplement breastfeeding with formula

  3. Continue breastfeeding and monitor the infant's bilirubin levels

  4. Phototherapy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Breast milk jaundice is a benign condition that typically resolves on its own. Breastfeeding should be continued and the infant's bilirubin levels should be monitored closely.

Multiple choice

  1. To remove bilirubin from the infant's blood

  2. To replace the infant's blood with donor blood

  3. To correct the underlying cause of jaundice

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The goal of exchange transfusion in the treatment of neonatal jaundice is to remove bilirubin from the infant's blood.
