The function of an incentive spirometer is to encourage deep breathing. This device is commonly used in healthcare settings, especially for patients recovering from surgery or respiratory conditions. It helps patients take slow, deep breaths, which can aid in expanding the lungs and preventing complications like atelectasis (collapse of a part of the lung). By visualizing their progress on the spirometer, patients are motivated to reach specific goals, enhancing lung capacity and promoting better oxygenation.

In contrast, administering medications involves different devices or methods entirely, such as inhalers or injections. Measuring blood pressure typically requires a sphygmomanometer rather than a spirometer. Assessing heart rate is done with instruments like a pulse oximeter or a stethoscope, neither of which relate to the purposes of an incentive spirometer. Thus, the correct answer reflects the specialized role of the incentive spirometer in promoting lung health through guided breathing exercises.
