A medication used to relax the airways in the lungs to increase air flow is:

Bronchodilator

Doxycycline

Ace inhibitor

Anti-androgen therapy

Answer and Explanation

The Correct Answer is A

A. Bronchodilators are medications specifically designed to relax the muscles around the airways, making it easier to breathe by increasing airflow. They are commonly used in conditions like asthma and chronic obstructive pulmonary disease (COPD).
B. Doxycycline is an antibiotic used to treat bacterial infections. It has no direct effect on airway muscles or airflow.
C. ACE inhibitors are used primarily to treat high blood pressure and heart failure. They do not act on the airways and are not used to improve airflow.
D. Anti-androgen therapy is used to reduce levels of male hormones, typically in the treatment of prostate cancer or hormone-sensitive conditions. It has no role in bronchodilation or respiratory therapy.

Correct Answer is A

Explanation

A. The epiglottis is a flap of cartilage located at the base of the tongue that covers the trachea (windpipe) during swallowing. This directs food and liquids into the esophagus and prevents them from entering the airway.
B. The conchae (or turbinates) are structures inside the nasal cavity that help warm and humidify air, not related to swallowing food or liquids.
C. The glottis is the opening between the vocal cords that leads to the trachea, but it is not responsible for directing food into the esophagus.
D. The Adam's apple is part of the larynx and is primarily related to voice production, not swallowing.

A. When on bedrest, the patient is more prone to develop asthma, which can lead to pneumonia. B. Mucus pools in the lungs, providing a favorable environment for bacterial growth. C. The need for supplemental oxygen increases with bedrest, which then increases the risk of developing pneumonia. D. Many bacteria and viruses are present in the hospital that could lead to pneumonia.

Correct Answer is B

Explanation

A. Asthma is not typically linked to bedrest. Bedrest can lead to decreased lung expansion and impaired mucus clearance, which may increase the risk of infections like pneumonia, but it does not specifically increase the risk of asthma.
B. When a patient is immobile and unable to get out of bed, mucus can accumulate in the lungs, as normal coughing and deep breathing are reduced. This pooling of mucus provides an ideal environment for bacteria to grow, leading to pneumonia.
C. While supplemental oxygen might be needed for patients with certain respiratory conditions, it is not the primary risk factor for pneumonia in bedrest. In fact, oxygen therapy might be used to treat pneumonia.
D. Hospital-acquired infections, including pneumonia, are a concern, but the primary risk from bedrest is the inability to clear mucus effectively, not the presence of pathogens alone.
