A nurse is caring for four clients who have various types of drainage tubes.
Which of the following clients should the nurse identify as being at risk for hypokalemia?
The client who has an indwelling urinary catheter to gravity drainage
The client who has a chest tube to water seal
The client who has a nasogastric (NG) tube to suction
The client who has a tracheostomy tube attached to humidified oxygen
The Correct Answer is C
Choice A rationale
The client who has an indwelling urinary catheter to gravity drainage is not at risk for hypokalemia. The kidneys regulate the balance of potassium by removing excess potassium into the urine. The use of a urinary catheter would not affect this process.
Choice B rationale
The client who has a chest tube to water seal is not at risk for hypokalemia. Chest tubes are used to treat conditions that can cause the lung to collapse, such as pneumothorax, hemothorax, or pleural effusion. They do not affect the body’s potassium levels.
Choice C rationale
The client who has a nasogastric (NG) tube to suction is at risk for hypokalemia. Hypokalemia, or low potassium levels, can occur with loss of gastric fluids because these fluids contain potassium. With an NG tube to suction, these fluids are being removed from the body, which can lead to a decrease in potassium levels.
Choice D rationale
The client who has a tracheostomy tube attached to humidified oxygen is not at risk for hypokalemia. A tracheostomy tube allows air to enter the lungs. It does not affect the body’s potassium levels.

Choice B rationale
Fluid volume deficit can occur in patients with Crohn’s disease due to diarrhea, a common symptom of the disease. However, it is not typically the primary nursing assessment.
Choice C rationale
Nutrition should be prioritized in the nursing assessment for a patient diagnosed with Crohn’s disease. Malnutrition can occur due to decreased appetite, malabsorption of nutrients, and increased nutritional needs due to inflammation.
Choice D rationale
While skin integrity can be a concern in patients with Crohn’s disease, particularly those with fistulas, it is not typically the primary nursing assessment.
