In a patient with liver cirrhosis, which of the following lab results would be expected?

Correct Answer: A

Rationale: In a patient with liver cirrhosis, increased bilirubin levels would be expected. Liver cirrhosis leads to impaired liver function, causing a decrease in the liver's ability to process bilirubin, leading to its accumulation in the blood. This results in elevated bilirubin levels. Decreased albumin levels (choice B) may occur in liver cirrhosis due to impaired liver synthesis of proteins, but it is not as specific as increased bilirubin levels. Increased liver enzymes (choice C) can be seen in liver damage but are not as characteristic as elevated bilirubin levels. Decreased platelet count (choice D) can occur in liver cirrhosis due to hypersplenism, but it is not as specific as increased bilirubin levels in this context.

Correct Answer: A

Rationale: Smoking is the correct answer as it is a well-established common cause of chronic obstructive pulmonary disease (COPD). Smoking leads to long-term damage to the lungs, contributing to the development of COPD. Choice B, asthma, is not a cause but a separate respiratory condition characterized by airway inflammation and hyperresponsiveness. Allergies, choice C, are not a direct cause of COPD but can exacerbate symptoms in individuals with existing COPD. Chronic bronchitis, choice D, is a type of COPD, not a cause of COPD itself, making it an incorrect choice in this context.

Correct Answer: B

Rationale: Administering oxygen is a priority intervention in heart failure because it helps improve oxygenation, alleviate hypoxemia, and reduce the workload on the heart. Oxygen therapy is crucial in managing acute heart failure exacerbations. While diuretics (Choice A) are commonly used in heart failure to reduce fluid overload, administering oxygen takes precedence due to its immediate impact on oxygen delivery. Beta-blockers (Choice C) and vasodilators (Choice D) are also important in heart failure management, but in the acute setting, ensuring adequate oxygen supply is the priority.

Correct Answer: C

Rationale: The primary goal in the treatment of asthma is to improve airflow. Asthma is characterized by airway inflammation, constriction, and increased mucus production, leading to airflow limitation. Improving airflow helps ensure adequate oxygenation and reduces symptoms. While reducing inflammation and airway constriction are important aspects of asthma management, the primary goal is to optimize airflow to improve respiratory function and quality of life.
