A nurse is teaching the mother of an infant about the importance of immunizations. The nurse should teach her that active immunity:

Correct response:

Question 2 See full question

A nurse is conducting an assessment of a neonate born 3 hours ago. Which finding makes the nurse suspect a congenital hip dislocation?

Correct response:

• Unequal gluteal folds

Explanation:

Unequal gluteal folds are a sign of congenital hip dislocation. Other signs include unequal thighs, limited adduction of the affected side, and shortening of the limb on the affected side. Crepitus of the affected hip isn't felt, but an audible click may be heard when the hip on the affected side is adducted.

Remediation:

Question 3 See full question

Twenty-four hours after cesarean birth, a neonate at 30 weeks’ gestation is diagnosed with respiratory distress syndrome (RDS). When explaining to the parents about the cause of this syndrome, the nurse should include a discussion about an alteration in the body’s secretion of which substance?

• surfactant

Explanation:

RDS, previously called hyaline membrane disease, is a developmental condition involving a decrease in lung surfactant leading to improper expansion of the lung alveoli. Surfactant contains a group of surface-active phospholipids, of which one component—lecithin—is the most critical for alveolar stability. Surfactant production peaks at about 35 weeks’ gestation. This syndrome primarily attacks preterm neonates, although it can also affect term and postterm neonates. Altered somatotropin secretion is associated with growth disorders such as gigantism or dwarfism. Altered testosterone secretion is associated with masculinization. Altered progesterone secretion is associated with spontaneous abortion during pregnancy.
