A client with suspected congestive heart failure undergoes a chest X-ray. The nurse should anticipate which finding that may be indicative of CHF?

A) This choice is incorrect because loop diuretics can lead to increased sodium excretion, potentially causing hypernatremia (high sodium levels) rather than hyponatremia (low sodium levels).

B) This choice is incorrect because loop diuretics do not typically cause hypocalcemia (low calcium levels). They primarily affect sodium, potassium, and water excretion.

C) This choice is incorrect because loop diuretics are more likely to cause hypokalemia (low potassium levels) rather than hyperkalemia (high potassium levels). Loop diuretics can increase potassium excretion, leading to a potential deficiency.

D) This choice is correct. Loop diuretics are potent potassium-wasting diuretics, meaning they increase potassium excretion in the urine, potentially causing hypokalemia. The nurse should closely monitor the client's potassium levels and provide potassium supplementation if necessary.

A) This choice is correct. Alcohol abuse can lead to dilated cardiomyopathy, a condition in which the heart becomes enlarged and weakened, contributing to congestive heart failure. Chronic alcohol consumption can cause toxic effects on the heart muscle, leading to impaired pumping function.

B) This choice is incorrect because malnutrition, while it can impact overall health, is not a direct precipitating cause of congestive heart failure. However, malnutrition can exacerbate heart failure symptoms and weaken the heart further.

C) This choice is incorrect because a sedentary lifestyle can be a risk factor for heart disease, including congestive heart failure, but it is not a direct precipitating cause of the client's condition in this scenario.

D) This choice is incorrect because occupational exposure to toxins can have health implications, but it is not directly related to the client's signs and symptoms of congestive heart failure in this case.
