Order: Magnesium Sulfate 1 gram in 100mLs 0.09% NaCl over 2 hours. IV tubing has a drop factor of 30 gtt/mL. How many drops per minute will you give?
25 gtt/min
1500 gtt/min
50 gtt/min
83 gtt/min
The Correct Answer is C
A. 25 gtt/min: Calculating the correct rate reveals that this is not the correct answer.
B. 1500 gtt/min: This rate is too high; the calculation does not support this answer.
C. 50 gtt/min: To calculate: (100 mL / 120 min) × 30 gtt/mL = 50 gtt/min.
D. 83 gtt/min: This is too high based on the calculation.

Correct Answer is C
Explanation
A. Calcium 10 mg/dL: This calcium level is within the normal range (8.6-10.2 mg/dL) and does not require intervention.
B. Sodium 136 mEq/L: This sodium level is within the normal range (135-145 mEq/L).
C. Potassium 2.3 mEq/L: This potassium level is critically low; bumetanide is a loop diuretic that can cause hypokalemia, which can lead to dangerous cardiac dysrhythmias.
D. Magnesium 1.4 mEq/L: While slightly low, this magnesium level is only mildly decreased and not as immediately concerning as the potassium level.
Correct Answer is D
Explanation
A. "I will avoid crossing my legs at the knees." Crossing the legs can restrict blood flow and should be avoided in PVD.
B. "I will use a thermometer to check the temperature of my bath water." Due to reduced sensation, checking the water temperature can prevent burns.
C. "I will not go barefoot." Going barefoot increases the risk of injury or infection, especially with impaired circulation.
D. "I will wear stockings with elastic tops." Stockings with tight elastic tops can restrict blood flow, worsening symptoms in PVD.
