The parents of a child with acid-base imbalance ask the nurse about mechanisms that regulate acid-base balance. Which statement by the nurse accurately explains the mechanisms regulating acid-base balance in children?

When caring for a neonate with a suspected tracheoesophageal fistula (TEF), nursing care should include elevating the head but giving nothing by mouth. Tracheoesophageal fistula is a condition where an abnormal connection exists between the trachea and oesophagus, leading to the passage of air and secretions between these structures. Feeding the infant orally can result in aspiration of feedings into the lungs, which can cause respiratory distress and complications. Therefore, it is important to keep the neonate in an upright position to reduce the risk of aspiration until a definitive diagnosis and treatment plan are established.

elevating the head for feedings in (option B), is not appropriate in this case as oral feedings should be avoided until the tracheoesophageal fistula is addressed.

avoiding suction unless the infant is cyanotic in (option C), is not correct. Suctioning may be necessary in neonates with suspected tracheoesophageal fistula to clear secretions and maintain a patent airway.

feeding glucose water only in (option D), is not an appropriate intervention for a neonate with a suspected tracheoesophageal fistula. In this situation, all oral feedings should be withheld until further evaluation and management.

Juvenile arthritis should be suspected in a child who exhibits joint swelling and pain lasting
longer than 6 weeks. Juvenile arthritis refers to a group of chronic inflammatory conditions
that affect the joints in children and adolescents. Persistent joint swelling and pain are
common symptoms of juvenile arthritis and are often accompanied by other signs such as
morning stiffness, limited range of motion, and joint warmth.
, frequent fractures in (option A) is not correct because it, is not typically associated with
juvenile arthritis. Fractures are more commonly associated with conditions affecting bone
strength, such as osteoporosis or certain genetic disorders.

lurching and abnormal gait with limited abduction in (option A) is not correct because it,
may be seen in certain musculoskeletal conditions or hip joint abnormalities, but it is not
specific to juvenile arthritis.
increased joint mobility in (option D) is incorrect because it, is not typically associated with
juvenile arthritis. In fact, joint stiffness and limited range of motion are more characteristic of
this condition.
