What type of cells secrete glucagon?

C. Pursed lip breathing is a technique that can help patients with acute dyspnea by improving ventilation, prolonging exhalation, and reducing the work of breathing. It helps to keep the airways open longer and makes it easier to get rid of excess carbon dioxide, which can provide quick relief from acute shortness of breath.
A. Teaching the patient about using accessory muscles for breathing can be beneficial in managing chronic respiratory issues, but it is not an immediate intervention.
B. Understanding the cause of dyspnea is important for treatment planning but it is not the first action to take when the patient is experiencing acute shortness of breath.
D. The Sims position, where the patient lies on their side with the lower arm behind the back and the upper leg flexed, is not typically used for relieving acute respiratory distress.

B. Morning is considered the ideal time for collecting a sputum specimen. Overnight, mucus accumulates in the respiratory tract because the patient is less active and not clearing their throat or coughing as much. This means that the mucus is more concentrated and has had time to build up, providing a more substantial and representative sample of what is in the lungs.
A. Collecting a sputum specimen at bedtime is generally not ideal. By the end of the day, the patient’s respiratory tract might have cleared some of the accumulated mucus naturally through coughing or other activities.
C. Collecting a sputum specimen after meals is not recommended. Eating can introduce food particles and bacteria from the mouth into the sputum, contaminating the sample.
D. Starting antibiotics before collecting a sputum specimen can alter the bacterial flora present in the respiratory tract. This can lead to a false-negative result or an inaccurate representation of the pathogens causing the infection.
