A nurse is assisting with the care of a client who is placed on supplemental oxygen for hypoxia. The nurse should identify that which of the following findings indicate the intervention was effective?

Choice A reason: Rigid abdomen is not a sign of diarrhea, but rather a sign of peritonitis, which is an inflammation of the abdominal lining. Peritonitis can be caused by a perforated ulcer, appendicitis, or diverticulitis.

Choice B reason: Dehydration is a sign of diarrhea, as it indicates a loss of fluid and electrolytes from the body. Dehydration can cause symptoms such as dry mouth, thirst, decreased urine output, sunken eyes, and low blood pressure.

Choice C reason: Hypothermia is not a sign of diarrhea, but rather a sign of low body temperature. Hypothermia can be caused by exposure to cold, shock, or infection.

Choice D reason: Decreased bowel sounds are not a sign of diarrhea, but rather a sign of ileus, which is a lack of intestinal activity. Ileus can be caused by surgery, medication, or obstruction.

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.
