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:

Tachycardia, or a rapid heart rate, is not typically an adverse effect of oxygen therapy. Oxygen therapy is often used to help people with conditions like COPD, COVID-19, emphysema, and sleep apnea get enough oxygen to function and stay well. While tachycardia can be a symptom of these conditions, it is not directly caused by the oxygen therapy itself.

Choice B rationale:

Cracks in the oral mucous membranes can indeed be an adverse effect of oxygen therapy. Oxygen therapy involves the delivery of highly concentrated oxygen, which can cause irritation and dryness in the airways, including the oral mucous membranes. This can lead to cracks and discomfort in the mouth. Therefore, it’s important for healthcare providers to monitor patients receiving oxygen therapy for signs of this adverse effect.

Excessive pulmonary secretions are not typically a direct adverse effect of oxygen therapy. While conditions that often require oxygen therapy, such as pneumonia and COPD, can lead to increased pulmonary secretions, these are symptoms of the underlying disease rather than the oxygen therapy itself.

Choice D rationale:

Poor skin turgor is not typically an adverse effect of oxygen therapy. Skin turgor refers to the elasticity of the skin, and poor skin turgor is often a sign of dehydration. While oxygen therapy can cause dryness of the mucous membranes, it does not typically affect the hydration status of the skin.

Choice A rationale:

Caffeinated beverages are known to cause diarrhea. Caffeine naturally occurs in many foods and drinks, including coffee and chocolate. It speeds up the digestive system and can cause loose stools. In addition, caffeine can irritate the stomach lining during digestion. Therefore, it’s important for the nurse to educate the patient about the potential effects of caffeinated beverages on their digestive system.

Choice B rationale:

Low-fiber cereal is not typically associated with triggering diarrhea. In fact, foods that are low in fiber can actually help firm up stools and are often recommended for individuals experiencing diarrhea. Therefore, while it’s not harmful, it’s not a primary concern for patients with diarrhea.

Choice C rationale:

White rice is another food that does not typically cause diarrhea. Similar to low-fiber cereal, white rice can help firm up stools and is often recommended for individuals experiencing diarrhea. It’s not a primary concern for patients with diarrhea.

Choice D rationale:

Ripe bananas do not typically cause diarrhea. They are actually part of the BRAT diet (Bananas, Rice, Applesauce, Toast), which is often recommended for individuals experiencing diarrhea. Therefore, it’s not a primary concern for patients with diarrhea.

In conclusion, when educating a patient about food and drinks that can trigger diarrhea, the nurse should include caffeinated beverages as they can potentially cause diarrhea. However, low-fiber cereal, white rice, and ripe bananas are not typically associated with triggering diarrhea.
