A child has a chronic, nonproductive cough and diffuse wheezing during the expiratory phase of respiration. This suggests which respiratory condition?
Foreign body in the trachea.
Bronchiolitis.
Asthma.
Pneumonia.
The Correct Answer is C
The correct answer is choice C. Asthma.
Choice A rationale:
A foreign body in the trachea can cause acute respiratory distress and a sudden cough, but it is unlikely to cause chronic nonproductive cough and diffuse wheezing during the expiratory phase of respiration. The symptoms in the scenario are more suggestive of a chronic condition.
Choice B rationale:
Bronchiolitis primarily affects infants and young children, causing symptoms such as fever, rhinorrhea, and wheezing. While wheezing can be present, the diffuse wheezing during the expiratory phase described in the scenario is more characteristic of asthma.
Choice C rationale:
Asthma is characterized by chronic inflammation of the airways, leading to episodes of bronchoconstriction and increased airway reactivity. The chronic, nonproductive cough and diffuse wheezing during the expiratory phase are classic signs of asthma. Expiratory phase wheezing occurs due to the narrowing of the smaller airways during expiration.
Choice D rationale:
Pneumonia is an infection of the lung tissue and can cause productive cough, fever, and crackles on auscultation. While wheezing might occur in pneumonia due to inflammation and narrowing of the airways, it's not the most likely cause of the symptoms described in the scenario.

Correct Answer is A
Explanation
The correct answer is choice A. Meconium ileus.
Choice A rationale:
Meconium ileus. This is the earliest recognizable clinical manifestation of cystic fibrosis (CF). Meconium ileus refers to the blockage of the small intestine by thick, sticky meconium, the earliest stool of a newborn. It occurs in the first 24-48 hours of life and can be a sign of underlying cystic fibrosis.
Choice B rationale:
Foul-smelling, frothy, greasy stools. Foul-smelling, frothy, greasy stools are characteristic of malabsorption, which can occur in cystic fibrosis. However, this manifestation typically appears after meconium ileus and is not the earliest recognizable clinical sign.
Choice C rationale:
History of poor intestinal absorption. While poor intestinal absorption is a common consequence of cystic fibrosis, it is not one of the earliest recognizable clinical manifestations. Meconium ileus takes precedence as the primary early sign.
Choice D rationale:
Recurrent pneumonia and lung infections. Recurrent pneumonia and lung infections are common in later stages of cystic fibrosis due to the buildup of thick mucus in the respiratory tract. However, they are not among the earliest recognizable clinical manifestations of the disease. Meconium ileus is the earliest indicator in this context.
Correct Answer is ["C","D"]
Explanation
The correct answers are choices C. Novolin R, and D. NovoLog.
Choice A rationale:
Novolin N is an intermediate-acting insulin, not rapid or short acting. It has a slower onset and longer duration of action, making it unsuitable for rapid blood sugar control.
Choice B rationale:
Lantus is a long-acting insulin that provides basal insulin coverage and has a relatively steady effect over 24 hours. It is not rapid or short acting and is used to provide a baseline level of insulin, not for immediate blood sugar control.
Choice C rationale:
Novolin R, also known as regular insulin, is a short-acting insulin with an onset of about 30 minutes and a peak effect around 2 to 3 hours. It is often used to cover mealtime blood sugar elevations and is suitable for short-term blood sugar control.
Choice D rationale:
NovoLog is a rapid-acting insulin analog with an onset of about 15 minutes and a peak effect within 1 to 2 hours. It is designed to mimic the body's rapid insulin release after meals, making it effective for controlling postprandial blood sugar levels.
