Crackles are adventitious lung sounds that can be heard on auscultation and are commonly associated with pneumonia. They are caused by the movement of air through fluid-filled or collapsed alveoli, indicating inflammation and infection in the lungs.

Choice B rationale:

Crepitus is a different respiratory finding and is not typically associated with pneumonia. Crepitus is a crackling or grating sensation that can be felt under the skin, often caused by subcutaneous emphysema or gas trapped in the tissues, not within the lungs.

Choice C rationale:

Stridor is a harsh, high-pitched sound heard during inspiration and is usually indicative of upper airway obstruction, not pneumonia. It can be caused by conditions such as croup or anaphylaxis.

Choice D rationale:

Decreased fremitus is not a specific manifestation of pneumonia. Fremitus is the vibration felt when the patient speaks and is transmitted through the chest wall. In pneumonia, increased fremitus may be observed due to the consolidation of lung tissue with fluid or pus, not decreased fremitus.

A. "Bedside water pitchers should be covered after being filled.". B. "Dressings that get wet in the shower should be allowed to dry out.". C. "Used needles should be placed in the sharps container at the nurses' station.". D. "Drainage bottles should be emptied when they become full.".

Correct Answer is A

Explanation

Choice A rationale:

Covering bedside water pitchers after being filled helps reduce the risk of contamination and infection by preventing the entry of airborne pathogens or debris.

Choice B rationale:

Allowing dressings that get wet in the shower to dry out is not an effective infection control strategy. Wet dressings can become a breeding ground for bacteria, and it is important to change wet dressings promptly to minimize the risk of infection.

Choice C rationale:

Used needles should be immediately disposed of in sharps containers, not placed at the nurses' station. Placing used needles in the sharps container promptly helps prevent accidental needlestick injuries and potential transmission of infections.

Choice D rationale:

Drainage bottles should be emptied regularly to prevent overfilling, but they should not be allowed to become full. Regular emptying ensures proper functioning and reduces the risk of spillage or contamination in the client care area.
