A nurse is caring for a client who has COPD. The nurse should identify that the client is at risk for which of the following acid-base imbalances?

Choice A reason: Requesting that the provider prescribe a stool softener is not the best action for the nurse to take, as it may cause dependency, dehydration, or electrolyte imbalance. The nurse should try non-pharmacological interventions first, such as increasing fluid and fiber intake, promoting physical activity, and establishing a regular bowel routine.

Choice B reason: Adding fluid and fiber to the diet is the best action for the nurse to take, as it helps to soften the stool, increase the bulk, and stimulate peristalsis. The nurse should encourage the client to drink at least 2 liters of water per day and eat foods rich in fiber, such as fruits, vegetables, and whole grains.

Choice C reason: Promoting active range-of-motion activities is a good action for the nurse to take, as it helps to improve circulation, muscle tone, and bowel motility. The nurse should assist the client to perform exercises that are appropriate for their level of mobility and endurance.

Choice D reason: Avoiding gas-producing foods is not a necessary action for the nurse to take, as it does not directly affect constipation. Gas-producing foods, such as beans, cabbage, and broccoli, may cause bloating and discomfort, but they do not cause or worsen constipation.

Choice A reason: Dry skin is not a sign of respiratory alkalosis. Respiratory alkalosis is a condition where the blood pH is too high due to excessive loss of carbon dioxide through rapid breathing. Dry skin can be caused by dehydration, cold weather, or skin conditions.

Choice B reason: Diarrhea is not a sign of respiratory alkalosis. Diarrhea is a condition where the stool is loose and watery due to increased intestinal motility or infection. Diarrhea can cause metabolic acidosis, which is a condition where the blood pH is too low due to excessive loss of bicarbonate.

Choice C reason: Abdominal pain is not a sign of respiratory alkalosis. Abdominal pain is a symptom that can have many causes, such as gastritis, appendicitis, or irritable bowel syndrome. Abdominal pain can also cause hyperventilation due to anxiety or discomfort, but it is not a direct result of respiratory alkalosis.

Choice D reason: Hyperventilation is a sign of respiratory alkalosis. Hyperventilation is a condition where the breathing rate is faster than normal, causing excess carbon dioxide to be expelled from the lungs. This lowers the partial pressure of carbon dioxide in the blood, which increases the blood pH and causes alkalosis. Hyperventilation can be caused by anxiety, fever, pain, or lung diseases.
