A nurse is gathering data on a patient who has diarrhea.
Which of the following findings is a sign of hypokalemia?
Hypertension.
Cerebral edema.
Muscle weakness.
Hyperactive bowel sounds.
The Correct Answer is C
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.

Correct Answer is B
Explanation
Choice A rationale:
Administering insulin to a client who is hyperventilating due to respiratory alkalosis would not be the appropriate action. Insulin is used to lower blood glucose levels in clients with hyperglycemia, such as those with diabetes mellitus. It does not directly address the issues of hyperventilation or respiratory alkalosis.
Choice B rationale:
Having the client breathe into a paper bag is the correct action in this case. When a person hyperventilates, they exhale more carbon dioxide (CO2) than they produce. This can lead to a state of respiratory alkalosis, where the blood becomes too alkaline due to the low levels of CO2. By breathing into a paper bag, the client re-inhales some of the exhaled CO2, helping to restore the balance of gases in the blood and alleviate the symptoms of respiratory alkalosis.
Choice C rationale:
Administering sodium bicarbonate to a client who is hyperventilating and has respiratory alkalosis would not be the appropriate action. Sodium bicarbonate is an alkalinizing agent used to treat conditions where there is too much acid in the body, such as metabolic acidosis. In this case, the client’s body is too alkaline due to the respiratory alkalosis, so administering an alkalinizing agent would exacerbate the condition.
Choice D rationale:
Having the client place their head between their knees would not be the appropriate action for a client who is hyperventilating due to respiratory alkalosis. This position is often used to help alleviate symptoms of dizziness or fainting, but it does not address the underlying issue of the imbalance of gases in the blood due to hyperventilation.
Correct Answer is B
Explanation
Choice A rationale:
Metabolic alkalosis Metabolic alkalosis is a condition that occurs when your body has too many bases. It can occur due to prolonged vomiting, use of diuretics, or an overuse of antacids. In the context of Chronic Obstructive Pulmonary Disease (COPD), metabolic alkalosis is not typically a direct result of the disease. COPD primarily affects the respiratory system and does not directly cause an imbalance of bases in the body.
Choice B rationale:
Respiratory acidosis Respiratory acidosis is a condition that occurs when the lungs can’t remove enough carbon dioxide (CO2). This leads to a buildup of CO2 in the body, causing the pH of the blood to decrease and become more acidic. This is the most common acid-base imbalance seen in patients with COPD1. COPD can cause an alteration in respiratory exchanges, leading to retention of CO21. The consequence of hypercapnia due to alteration of gas exchange in COPD patients mainly consists in an increase of H+ concentration and development of respiratory acidosis.
Respiratory alkalosis Respiratory alkalosis is a condition that occurs when there is too little carbon dioxide in the body, often due to hyperventilation. In the context of COPD, this is less likely because COPD patients often have difficulty expelling carbon dioxide, not an excess of it being expelled.
Choice D rationale:
Metabolic Acidosis Metabolic acidosis occurs when the body produces too much acid, or when the kidneys are not removing enough acid from the body. This can occur due to conditions such as kidney disease, lactic acidosis, or ketoacidosis. While COPD can have wide-ranging effects on the body, it does not typically cause metabolic acidosis directly.
