At what age is the first dose of the hepatitis A vaccine recommended to be started?

Correct Answer: A

Rationale: The correct answer is A: 1 year. The hepatitis A vaccine is now recommended for all children starting at age 1 year (i.e., 12 to 23 months). This is due to the recognition of hepatitis A as a significant child health problem, especially in areas with high infection rates. The virus is primarily spread through fecal-oral transmission, person-to-person contact, ingestion of contaminated food or water, and rarely through blood transfusion. Administering the first dose at 1 year helps protect children from this infection. Choices B and C are incorrect as the vaccine is not recommended at 1 month or 12 years. Choice D is also incorrect as the hepatitis A vaccine is recommended at a specific age to prevent the infection.

Correct Answer: C

Rationale: The NCAST Feeding Scale is the most suitable tool to evaluate maternal and newborn attachment behaviors during feedings. It focuses on observing the interaction between the parent and infant, providing insights into their bonding. The Apgar score is used to assess a neonate's immediate transition to life outside the womb, not specifically maternal and newborn attachment behaviors. The Ballard scale is used to estimate gestational age, not to assess attachment behaviors. The Brazelton Neonatal Behavioral Assessment Scale is designed to evaluate a newborn's responses to various stimuli, not specifically maternal and newborn attachment behaviors.

Correct Answer: B

Rationale: The correct consideration when using a bulb syringe to suction a neonate after delivery is to clear the mouth and pharynx before the nasal passages to prevent aspiration of amniotic fluid. Compressing the bulb syringe before insertion is important to create suction. Using two bulb syringes is unnecessary, as one is sufficient for both the mouth/pharynx and nasal passages. It is not recommended to continue using a bulb syringe until all secretions are removed; instead, mechanical suction can be employed if more forceful removal of secretions is required.

Correct Answer: B

Rationale: Hydrocephalus is the most commonly associated problem with myelomeningocele, present in 80% to 90% of affected children. Biliary atresia and tracheoesophageal fistula are not typically associated with myelomeningocele. Craniostenosis refers to the premature closing of cranial sutures and is not a common issue seen with myelomeningocele.

Correct Answer: C

Rationale: Preventing heat loss in a low birth weight (LBW) infant is crucial in maintaining a neutral thermal environment. The use of cotton blankets is recommended over wool blankets. Avoiding disposable diapers is not directly related to maintaining a neutral thermal environment. While monitoring temperatures is important, the key intervention is preventing heat loss to ensure the infant's survival.
