A nurse is caring for an infant who has inadequate motility of part of the intestine resulting in a mechanical obstruction. The nurse should identify this finding as a manifestation of which of the following disorders?
Hirschsprung’s disease.
Encopresis.
Pyloric stenosis.
Enterocolitis.
The Correct Answer is A
Choice A rationale
Hirschsprung’s disease is characterized by inadequate motility of part of the intestine, resulting in a mechanical obstruction. This condition is caused by the absence of ganglion cells in the affected segment of the intestine, leading to a lack of peristalsis and subsequent obstruction.
Choice B rationale
Encopresis is a condition characterized by the repeated passage of feces into inappropriate places, such as clothing or the floor. It is not associated with inadequate motility of the intestine or mechanical obstruction.
Choice C rationale
Pyloric stenosis is a condition characterized by the narrowing of the pylorus, which leads to obstruction of the passage of food from the stomach to the small intestine. It is not associated with inadequate motility of the intestine.
Choice D rationale
Enterocolitis is an inflammation of the intestine and colon. It is not associated with inadequate motility of the intestine or mechanical obstruction.

Correct Answer is C
Explanation
Choice A rationale
Budesonide via dry-powder inhaler is a corticosteroid used for long-term control of asthma. It is not effective for immediate relief of acute asthma exacerbations.
Choice B rationale
Cromolyn via metered-dose inhaler is a mast cell stabilizer used for long-term control of asthma. It is not effective for immediate relief of acute asthma exacerbations.
Choice C rationale
Albuterol via jet nebulizer is a short-acting beta-adrenergic agonist that provides rapid bronchodilation. It is the medication of choice for immediate relief of acute asthma exacerbations.
Choice D rationale
Montelukast orally is a leukotriene receptor antagonist used for long-term control of asthma. It is not effective for immediate relief of acute asthma exacerbations.
Correct Answer is A
Explanation
Choice A rationale
A 13% weight loss indicates severe dehydration. Dehydration is classified based on the percentage of body weight lost, with severe dehydration being more than 10%6.
Choice B rationale
A bulging anterior fontanel is a sign of increased intracranial pressure, not dehydration. In dehydration, the fontanel is typically sunken due to fluid loss.
Choice C rationale
Bradypnea, or slow breathing, is not a common sign of dehydration. Dehydration often leads to tachypnea, or rapid breathing, as the body tries to compensate for fluid loss.
Choice D rationale
A capillary refill time of 3 seconds is within normal limits. In severe dehydration, capillary refill time is usually prolonged, indicating poor perfusion.
