A nurse is caring for four clients who have drainage tubes. The nurse should identify the client who has which of the following tubes as being at risk for hypokalemia?
A nephrostomy tube to a drainage bag
An NG tube to suction
An indwelling urinary catheter to gravity drainage
A chest tube to water-seal drainage
The Correct Answer is B
A. A nephrostomy tube to a drainage bag:
A nephrostomy tube drains urine from the kidney to a drainage bag. While it's essential for urinary drainage, it doesn't lead to significant potassium loss, as potassium is primarily excreted through the urine.
B. An NG tube to suction:
An NG tube (Nasogastric tube) is inserted through the nose into the stomach. When connected to suction, it can remove stomach contents, including gastric acid and potassium. Excessive suctioning can lead to significant potassium loss, potentially causing hypokalemia.
C. An indwelling urinary catheter to gravity drainage:
An indwelling urinary catheter drains urine from the bladder into a drainage bag by gravity. While potassium can be found in urine, the drainage through a catheter does not cause significant potassium loss unless there are underlying kidney issues, which are not specified in this scenario.
D. A chest tube to water-seal drainage:
A chest tube removes air or fluid from the pleural space around the lungs. While chest tubes are vital for lung expansion, they don't result in significant potassium loss as they are not connected to body fluids rich in potassium, like gastric acid or urine.

Correct Answer is ["10"]
Explanation
To calculate the number of milliliters (mL) of the hydroxyzine oral suspension to administer, you can use the following formula:
Dose (mL) = Ordered Dose (mg)/ Stock Concentration (mg/mL)
In this case:
- Ordered Dose = 50 mg
- Stock Concentration = 25 mg/5 mL
First, calculate the mg per mL from the stock concentration:
mg per mL = 25 mg/ 5 mL= 5 mg/mL
Now, use the formula to find the mL to administer:
Dose (mL) = 50 mg/ 5 mg/mL = 10 mL
So, the nurse should administer 10 mL of hydroxyzine oral suspension.
