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.

Correct Answer is C
Explanation
Choice A rationale
Waiting until the next appointment could potentially put both the mother and the baby at risk. Leakage of vaginal fluid could indicate premature rupture of membranes, which can lead to infection or premature labor.
Choice B rationale
While fetal movement is a good sign, it does not rule out potential complications associated with leakage of vaginal fluid. Therefore, this advice could lead to a delay in necessary medical intervention.
Choice C rationale
This is the most appropriate response. Leakage of vaginal fluid in a pregnant woman could be a sign of premature rupture of membranes, which can lead to complications such as infection or premature labor. Immediate medical attention is necessary to assess the situation and take appropriate action.
Choice D rationale
Asking the client to wait and see if the leakage changes could potentially delay necessary medical intervention. It’s important to seek immediate medical attention to assess the situation and take appropriate action.
Correct Answer is C
Explanation
Choice A rationale
It is not recommended to increase weight-bearing exercises during pregnancy. Weight-bearing exercises can put additional stress on the joints, which are already under strain due to the increased weight and changes in body shape during pregnancy.
Choice B rationale
It is not necessary to refrain from exercises that include stretching during pregnancy. In fact, gentle stretching can be beneficial to help alleviate some common discomforts of pregnancy such as backache and leg cramps.
Choice C rationale
Moderate exercise does improve circulation. Improved circulation can help reduce swelling, varicose veins, and feelings of fatigue, which are common during pregnancy.
Choice D rationale
It is not necessary to rest for 30 minutes before each new exercise. However, pregnant women should listen to their bodies and rest if they feel tired.
