A nurse is assisting with teaching a client who is preoperative for a sigmoid colostomy. Which of the following statements should the nurse include?

Choice A: Taking the client to the bathroom every 2 hours while awake is not an effective strategy for bowel training. This may disrupt the client's natural bowel rhythm and cause unnecessary stress and frustration. Bowel training aims to establish a regular and predictable time for elimination, not a frequent and arbitrary one¹².
Choice B: Taking the client to the bathroom when they have the urge to defecate is the best option for bowel training. This helps the client to respond to their body's signals and avoid suppressing or delaying the urge. It also reinforces the association between the urge and the act of defecation, which can improve bowel control and prevent constipation¹².
Choice C: Taking the client to the bathroom immediately before meals is not a good idea for bowel training. This may interfere with the client's appetite and digestion, as well as their social and emotional well-being. Bowel training should not be associated with negative or unpleasant feelings. Moreover, eating stimulates the gastrocolic reflex, which increases the motility of the colon and the likelihood of having a bowel movement after a meal¹³.
Choice D: Taking the client to the bathroom after they feel abdominal cramping is not a reliable method for bowel training. Abdominal cramping may indicate various conditions, such as irritable bowel syndrome, food intolerance, infection, or inflammation. It may not always be related to the need to defecate. Waiting for cramping to occur may also delay the evacuation and worsen the symptoms¹³.

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.
