A nurse is caring for a patient who has been prescribed a stool guaiac test.

The patient inquires about the purpose of the test.

How should the nurse respond?

Choice A rationale:

Crackles are a common symptom of pleural effusion. They are abnormal lung sounds that are heard when a patient with pleural effusion breathes in. The sound is caused by the opening of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration.

Choice B rationale:

Crepitus is not typically associated with pleural effusion. Crepitus is a crackling or grating sound or feeling produced by air in subcutaneous tissue or by the rubbing together of fragments of broken bone. In the context of respiratory health, crepitus might be felt if there is subcutaneous emphysema, where air gets into tissues under the skin covering the chest wall or neck.

Choice C rationale:

Substernal retractions are not a typical symptom of pleural effusion. Retractions are a sign of respiratory distress, but they are more commonly associated with conditions that cause upper airway obstruction or severe lung disease, such as asthma or pneumonia. Choice D rationale:

Dullness upon percussion is a classic sign of pleural effusion. When there is fluid in the pleural space, it prevents the normal resonant sound produced by the air-filled lungs from being heard. Instead, a dull sound is heard when the chest is percussed.

Choice A rationale:

Taking the patient to the bathroom every 2 hours while the patient is awake is not the most effective strategy for a bowel training program. This approach does not take into account the natural rhythms of the body and the patient’s personal comfort. It may lead to unnecessary trips to the bathroom, which can be physically and emotionally draining for the patient.

Choice B rationale:

This is the correct answer. A bowel training program aims to help the patient regain control over their bowel movements. Taking the patient to the bathroom when they have the urge to defecate aligns with this goal. It allows the patient to respond to their body’s signals, which can help improve their confidence and independence over time.

Choice C rationale:

Taking the patient to the bathroom immediately before meals is not the most effective strategy for a bowel training program. While it’s true that eating can stimulate bowel movements due to the gastrocolic reflex, this approach does not consider the patient’s comfort or individual needs. It may also disrupt the patient’s enjoyment of their meals.

Choice D rationale:

Waiting until the patient feels abdominal cramping is not the most effective strategy for a bowel training program. Abdominal cramping can be a sign of constipation or other digestive issues. It’s important to address these issues separately and not rely on them as indicators for when to take the patient to the bathroom.
