A nurse is reinforcing teaching with a client who reports constipation. Which of the following should the nurse discuss as causes of constipation? (Select all that apply.)

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.

The correct answer is B. Decreased deep tendon reflexes. Hyperkalemia can lead to muscle weakness and decreased reflexes, which is a common manifestation in patients with chronic kidney disease.

Choice A reason:

Wheezing is typically associated with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not hyperkalemia. Hyperkalemia affects the muscular function and cardiac conduction rather than causing respiratory symptoms.

Choice B reason:

Decreased deep tendon reflexes occur due to the effect of hyperkalemia on the neuromuscular junction and muscle excitability. In hyperkalemia, the resting membrane potential of muscle cells is less negative, which makes them less responsive to stimuli.

Choice C reason:

Hypoactive bowel sounds are generally associated with gastrointestinal issues and are not a direct manifestation of hyperkalemia. While severe hyperkalemia can affect smooth muscle function, it is not typically characterized by changes in bowel sounds.

Choice D reason:

Cerebral edema is not a manifestation of hyperkalemia. It is usually caused by traumatic brain injury, infections, or other neurological conditions. Hyperkalemia primarily affects muscular function and cardiac conduction.

Normal serum potassium levels range from about 3.5 to 5.0 mmol/L. Hyperkalemia is defined as serum potassium levels above 5.0 mmol/L.
