Correct Answer is C

Explanation

A. Examining the character of the sputum: While monitoring secretions is important, it does not necessarily indicate the need for immediate suctioning.
B. Monitoring the rate of respirations: An increased respiratory rate can indicate distress but is not a definitive cue for suctioning.
C. Auscultating the breath sounds: This helps identify the presence of secretions or airway obstruction and is a primary indicator for suctioning.
D. Determining the last time the patient was suctioned: Suctioning should be based on clinical need rather than a routine schedule.

A. sitting upright and forward with arms supported on an over the bed table B. semi-Fowler's position with a single pillow behind the head C. high Fowler's position without a pillow behind the head D. right lateral with the head of the bed elevated 45 degrees.

Correct Answer is A

Explanation

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.
