The nurse monitoring patients eating in the dining room of a skilled nursing facility notes that a patient begins choking. As the nurse prepares to deliver the Heimlich maneuver, the fist should be positioned:

A) In the morning immediately after breakfast. Performing postural drainage after eating may induce nausea and vomiting.
B) Shortly after the patient arises in the morning, before breakfast. This timing allows mucus to drain more effectively since the patient has been lying down overnight, and an empty stomach minimizes the risk of vomiting.
C) 30 minutes after lunch. Postural drainage should be performed at least 1 to 2 hours after meals to prevent gastrointestinal discomfort.
D) 1 hour after supper. While this timing is better than immediately after eating, morning sessions are generally more effective.

A. Sitting upright and forward with arms supported on an over-the-bed table: This tripod position allows for maximum lung expansion by reducing pressure on the diaphragm and improving airflow, especially for patients with chronic obstructive pulmonary disease (COPD).
B. Semi-Fowler's position with a single pillow behind the head: This position does not optimize lung expansion as well as the tripod position.
C. High Fowler's position without a pillow behind the head: Although better than lying flat, this position lacks arm support, which helps in leveraging accessory muscles for breathing.
D. Right lateral with the head of the bed elevated 45 degrees: This position is not beneficial for promoting effective lung expansion in patients with emphysema.
