Pediatric ATI Proctored Test

Correct Answer: A

Rationale: Beta-adrenergic agonists like albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.

Correct Answer: C

Rationale: Inability to lie supine is a specific sign of lower respiratory infection. This condition can cause discomfort or difficulty in breathing when lying flat, leading to a preference for an upright or semi-upright position. While cough and fever are common symptoms of respiratory infections, the inability to lie supine is more indicative of lower respiratory involvement.

Correct Answer: A

Rationale: Beta-adrenergic agonists like albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.

Correct Answer: D

Rationale: Coryza, also known as the common cold, is a viral infection that primarily affects the upper respiratory tract and is not typically associated with lower respiratory tract infections. Pneumonia, asthma, and bronchiolitis are conditions that commonly affect the lower respiratory tract, causing symptoms like cough, difficulty breathing, and chest pain.

Correct Answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.
