A nurse is collecting data on a client who has respiratory acidosis. Which of the following findings should the nurse expect?

The correct answer is c. Muscle weakness.

Choice A: Hypertension

Reason: Hypertension, or high blood pressure, is not a typical manifestation of hypokalemia. Hypokalemia primarily affects muscle function and the nervous system. While potassium imbalances can influence blood pressure, hypertension is more commonly associated with hyperkalemia (high potassium levels) rather than hypokalemia.

Choice B: Cerebral Edema

Reason: Cerebral edema, which is swelling of the brain, is not a known manifestation of hypokalemia. Hypokalemia affects muscle and nerve function, but it does not directly cause cerebral edema. This condition is more related to severe head injuries, infections, or other medical conditions.

Choice C: Muscle Weakness

Reason: Muscle weakness is a common and significant manifestation of hypokalemia. Potassium is crucial for muscle function, and low levels can lead to muscle weakness, cramps, and even paralysis in severe cases. This is because potassium helps in the transmission of nerve signals to muscles, and a deficiency disrupts this process.

Choice D: Hyperactive Bowel Sounds

Reason: Hyperactive bowel sounds are not typically associated with hypokalemia. In fact, hypokalemia can lead to decreased bowel motility, resulting in symptoms like constipation or ileus (a condition where the intestines do not move properly). This is due to the role of potassium in muscle contractions, including those in the digestive tract.

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.
