A nurse is gathering information from a patient who has been experiencing diarrhea for several days.
What symptoms should the nurse anticipate?

Choice A rationale:

Numbness in the fingers is not typically a symptom of respiratory acidosis. This condition is characterized by an excess of carbon dioxide (CO2) in the body, which leads to a decrease in the pH of your blood, making it too acidic. Numbness in the fingers could be a symptom of other conditions, such as peripheral neuropathy or Raynaud’s disease.

Choice B rationale:

Abdominal pain is also not a common symptom of respiratory acidosis. While abdominal discomfort can occur in a variety of conditions, it is not directly associated with the acid-base balance disturbance that characterizes respiratory acidosis.

Conditions that commonly cause abdominal pain include gastrointestinal issues like gastritis, appendicitis, or gallstones.

Choice C rationale:

Dry skin is not a symptom of respiratory acidosis. The skin’s condition can be influenced by many factors, including hydration, environmental conditions, and certain skin conditions like eczema or psoriasis. Respiratory acidosis, on the other hand, is a condition that affects the acid-base balance in the body due to alveolar hypoventilation.

Choice D rationale:

Lethargy is indeed a symptom of respiratory acidosis. This condition occurs when the lungs can’t remove enough CO2, leading to an increase in the acidity of the blood. Symptoms of respiratory acidosis vary according to how long you’ve had the condition and its severity. Initial symptoms can include anxiety, blurred vision, and shortness of breath. If left untreated or in severe cases, symptoms may include fatigue, lethargy, delirium, or confusion. Therefore, a nurse assessing a patient with respiratory acidosis should anticipate lethargy among other symptoms.

Choice A rationale:

The stool guaiac test does not check for bacteria in the feces. This test is used to detect hidden (occult) blood in a stool sample. It is the most common type of fecal occult blood test (FOBT)1.

Choice B rationale:

The stool guaiac test does not check for fat in the feces. The presence of fat in the feces is usually checked by a different test called a fecal fat test. The stool guaiac test is specifically designed to detect the presence of hidden blood in the stool.

Choice C rationale:

The stool guaiac test does not check for parasites in the feces. Parasites are typically detected using a stool ova and parasites (O&P) test. The stool guaiac test is used to detect hidden blood in the stool, which could be an indication of various conditions, including colon cancer or polyps in the colon or rectum.

Choice D rationale:

The stool guaiac test checks for hidden blood in the feces. This is the correct answer. The test can find blood even if you cannot see it yourself. Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum, though not all cancers or polyps bleed. If blood is detected through a fecal occult blood test, additional tests may be needed to determine the source of the bleeding. The stool guaiac test can only detect the presence or absence of blood — it can’t determine what’s causing the bleeding.
