Which adventitious breath sound would a nurse expect to auscultate in a child admitted with an asthma exacerbation?
Expiratory wheezing.
Inspiratory crackle.
Expiratory grunting.
Inspiratory stridor.
The Correct Answer is A
Choice A rationale:
Expiratory wheezing is characteristic of asthma exacerbation. It indicates airway constriction and narrowing, leading to difficulty in exhaling and resulting in a high-pitched sound during expiration.
Choice B rationale:
Inspiratory crackle is not typically associated with asthma. Crackles are often heard in conditions involving fluid-filled airways, such as pneumonia.
Choice C rationale:
Expiratory grunting is not a common finding in asthma. Grunting sounds may be present in infants with respiratory distress, indicating the difficulty they experience while exhaling.
Choice D rationale:
Inspiratory stridor is not a usual manifestation of asthma. Stridor is more commonly related to upper airway obstruction, often seen in croup or epiglottitis.

Correct Answer is B
Explanation
Choice A rationale:
The statement about an increased risk for developing obesity is accurate. However, this does not indicate a need for further education about Down syndrome, as obesity is a common concern in the general population as well.
Choice B rationale:
The statement about an increased risk for developing diabetes would indicate a need for further education. Individuals with Down syndrome are indeed at an elevated risk of developing diabetes, often in their early adulthood.
Choice C rationale:
The statement about an increased risk for developing cataracts is accurate. However, it is not a primary concern associated with Down syndrome in infancy.
Choice D rationale:
The statement about skeletal abnormalities is accurate. While individuals with Down syndrome can have certain skeletal features, this is not a critical concern during infancy.
Correct Answer is D
Explanation
Choice A rationale:
X-linked dominant disorders are characterized by a mutation on the X chromosome that results in the expression of the trait in both males and females. Hemophilia, however, is more commonly associated with males, which is not consistent with an X-linked dominant pattern.
Choice B rationale:
Autosomal recessive disorders require the inheritance of two mutated alleles, one from each parent, to express the trait. Hemophilia does not follow this pattern, as the patient's sisters do not have the condition despite having affected parents.
Choice C rationale:
Autosomal dominant disorders only require the inheritance of one mutated allele from an affected parent to express the trait. Hemophilia does not align with an autosomal dominant pattern, as the patient's sisters would likely be affected if it were.
Choice D rationale:
Hemophilia is a classic example of an X-linked recessive disorder. The gene responsible for producing clotting factor is located on the X chromosome, and males have only one X chromosome, making them more susceptible to the disorder. Females, with two X chromosomes, usually act as carriers unless both X chromosomes carry the mutation.
