Which structural defects constitute tetralogy of Fallot?

The correct answer is choice A. Meconium ileus.

Choice A rationale:

Meconium ileus. This is the earliest recognizable clinical manifestation of cystic fibrosis (CF). Meconium ileus refers to the blockage of the small intestine by thick, sticky meconium, the earliest stool of a newborn. It occurs in the first 24-48 hours of life and can be a sign of underlying cystic fibrosis.

Choice B rationale:

Foul-smelling, frothy, greasy stools. Foul-smelling, frothy, greasy stools are characteristic of malabsorption, which can occur in cystic fibrosis. However, this manifestation typically appears after meconium ileus and is not the earliest recognizable clinical sign.

Choice C rationale:

History of poor intestinal absorption. While poor intestinal absorption is a common consequence of cystic fibrosis, it is not one of the earliest recognizable clinical manifestations. Meconium ileus takes precedence as the primary early sign.

Choice D rationale:

Recurrent pneumonia and lung infections. Recurrent pneumonia and lung infections are common in later stages of cystic fibrosis due to the buildup of thick mucus in the respiratory tract. However, they are not among the earliest recognizable clinical manifestations of the disease. Meconium ileus is the earliest indicator in this context.

The correct answers are choices A and E: Institute cluster care to encourage adequate rest and Place on noninvasive oxygen monitoring.

Choice A rationale:

Institute cluster care to encourage adequate rest. This is a correct choice. Cluster care involves grouping nursing interventions together to minimize disruptions to the child's rest. Adequate rest is crucial for the healing process in infants with respiratory syncytial virus (RSV) bronchiolitis.

Choice B rationale:

Administer cough syrup. This choice is incorrect for RSV bronchiolitis. Cough syrup is not recommended for infants with bronchiolitis. RSV primarily affects the lower respiratory tract and can cause airway inflammation, making cough syrup potentially ineffective and unnecessary.

Choice C rationale:

Administer antibiotics. This choice is incorrect for RSV bronchiolitis. RSV is a viral infection, and antibiotics are ineffective against viruses. Antibiotics should only be used when there is a bacterial infection or a clear indication.

Choice D rationale:

Encourage infant to drink 8 ounces of formula every 4 hours. This choice is not the best approach for managing RSV bronchiolitis. Infants with RSV may experience decreased appetite due to respiratory distress. Smaller, more frequent feedings are often recommended to prevent overfeeding and aspiration.

Choice E rationale:

Place on noninvasive oxygen monitoring. This is a correct choice. RSV bronchiolitis can cause respiratory distress and compromise oxygenation. Noninvasive oxygen monitoring helps assess the child's oxygen levels and aids in determining the need for supplemental oxygen therapy.
