Correct Answer is A
Explanation
A. Decreased potassium level
NG tube drainage can lead to hypokalemia (low potassium levels) due to the loss of gastric fluids, which contain significant amounts of potassium. This choice is correct.
B. Decreased calcium level
Calcium levels are not directly affected by NG tube drainage.
C. Elevated magnesium level
NG tube drainage does not typically lead to elevated magnesium levels.
D. Elevated sodium level
NG tube drainage can result in hyponatremia (low sodium levels) due to the loss of gastric fluids. Elevated sodium levels are not expected in this situation.
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.
