A nurse is instructing a newly licensed nurse on how to obtain a fecal occult blood test from a patient.
What information should the nurse include?

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:

Hypertension is not typically a sign of hypokalemia. Hypokalemia, or low potassium levels, can cause symptoms like fatigue, muscle weakness, digestive problems, and frequent urination. Hypertension, or high blood pressure, is not commonly associated with hypokalemia.

Choice B rationale:

Cerebral edema, or swelling in the brain, is not a common symptom of hypokalemia. Hypokalemia is more likely to cause symptoms related to muscle function and digestion, as potassium is an essential mineral that helps regulate muscle contractions, maintain healthy nerve function, and regulate fluid balance.

Choice C rationale:

Muscle weakness is a common symptom of hypokalemia. Potassium helps regulate muscle contractions. When blood potassium levels are low, your muscles produce weaker contractions. This can result in symptoms like muscle weakness and fatigue.

Choice D rationale:

Hyperactive bowel sounds are not typically associated with hypokalemia. Hypokalemia can cause digestive problems, but these are more likely to be issues like constipation rather than increased bowel sounds.
