Extract:
Question 1 of 5
The nurse knows that children are more susceptible to respiratory tract infections owing to physiological differences. These childhood differences, adverts an adult, include:
Correct Answer: D
Rationale: Although a child has fewer alveoli than an adult, the child's respiratory rate is faster. Although a child may use diaphragmatic breathing, the adult exchanges a larger volume of air. The adult has a larger number of alveoli than a child. The child's chest is rounded whereas the adult chest is more of an oval shape, and the child does exchange a smaller volume of air than an adult.
Question 2 of 5
The client at 34 weeks gestation is admitted with a diagnosis of gestational hypertension. Which assessment finding requires immediate intervention?
Correct Answer: C
Rationale: Absence of deep tendon reflexes in gestational hypertension suggests magnesium toxicity (if receiving magnesium sulfate) or severe neurological complications requiring immediate intervention. The other findings while concerning are less urgent.
Question 3 of 5
A five-month-old infant is admitted to the ER with a temperature of 103.6°F and irritability. The mother states that the child has been listless for the past several hours and that he had a seizure on the way to the hospital. A lumbar puncture confirms a diagnosis of bacterial meningitis. The nurse should assess the infant for:
Correct Answer: B
Rationale: Tenseness of the anterior fontanel indicates increased intracranial pressure in bacterial meningitis due to inflammation. The other findings are not specific to meningitis in infants.
Question 4 of 5
Which of the following statements describes Piaget's stage of concrete operations?
Correct Answer: C

Question 5 of 5
The mother of a one-year-old with sickle cell anemia wants to know why the condition didn't show up in the nursery. The nurse's response is based on the knowledge that:
Correct Answer: D
Rationale: Fetal hemoglobin (HbF), predominant in newborns, inhibits sickling in sickle cell anemia, delaying symptoms until HbF decreases around 6 months. Newborn screening exists, and infections can trigger crises later.
