A 3-month-old is admitted with severe diarrhea. Yesterday, the infant weighed 11 pounds (5 kg). Today, this infant weighs 9 pounds, 8 ounces (4.3 kg). Based on this information, the nurse documents that the infant has:
Failure to thrive.
Malabsorption syndrome.
Severe dehydration.
Risk for fluid volume deficit.
The Correct Answer is C
Choice A rationale
Failure to thrive is a condition where a child does not gain weight or grow as expected. While severe diarrhea can contribute to failure to thrive, the immediate concern in this scenario is the significant weight loss indicating severe dehydration.
Choice B rationale
Malabsorption syndrome involves the inability to absorb nutrients properly, leading to malnutrition and weight loss. However, the acute weight loss in this case is more indicative of severe dehydration.
Choice C rationale
Severe dehydration is characterized by significant fluid loss, which can be life-threatening in infants. The weight loss from 11 pounds to 9 pounds, 8 ounces indicates a substantial fluid loss, pointing to severe dehydration.
Choice D rationale
Risk for fluid volume deficit is a potential diagnosis, but the significant weight loss and clinical presentation indicate that the infant is already experiencing severe dehydration.

Correct Answer is D
Explanation
Choice A rationale
A sputum culture can help identify respiratory infections but is not definitive for diagnosing cystic fibrosis.
Choice B rationale
Stool fat content analysis can indicate malabsorption issues but is not specific to cystic fibrosis.
Choice C rationale
Pulmonary function tests assess lung function but do not confirm a diagnosis of cystic fibrosis.
Choice D rationale
The sweat chloride test is the gold standard for diagnosing cystic fibrosis. It measures the concentration of chloride in sweat, which is elevated in individuals with cystic fibrosis due to defective chloride transport in sweat glands.
Correct Answer is B
Explanation
Choice A rationale
Montelukast is a leukotriene receptor antagonist used for long-term control and prevention of asthma symptoms. It is not a rescue medication and does not provide immediate relief during an acute asthma attack. Montelukast works by reducing inflammation and preventing bronchoconstriction, but its effects are not rapid enough to address the immediate needs of a patient experiencing an acute asthma attack.
Choice B rationale
Albuterol is a short-acting beta-agonist (SABA) that provides rapid bronchodilation and is the first-line treatment for acute asthma attacks. It works by relaxing the smooth muscles in the airways, leading to quick relief of bronchospasm and improved airflow. Administering albuterol promptly can help alleviate symptoms and prevent the progression of an asthma attack, making it the priority medication in this scenario.
Choice C rationale
Fluticasone is an inhaled corticosteroid used for long-term control of asthma. It helps reduce inflammation in the airways and prevent asthma symptoms but is not effective as a rescue medication during an acute asthma attack. Inhaled corticosteroids are typically used as part of a daily maintenance regimen to manage chronic asthma and prevent exacerbations.
Choice D rationale
Budesonide is another inhaled corticosteroid used for long-term asthma control. Like fluticasone, it helps reduce airway inflammation and prevent asthma symptoms but is not suitable for immediate relief during an acute asthma attack. Inhaled corticosteroids are important for managing chronic asthma but do not provide the rapid bronchodilation needed in an emergency situation.
