Which of the following solutions can be administered with a blood component?
0.9% sodium chloride
Lactated Ringers solution
5% dextrose/0.2% sodium chloride
5% dextrose/0.45% sodium chloride
The Correct Answer is A
A. 0.9% sodium chloride: Normal saline (0.9% sodium chloride) is the standard solution that can be administered with blood products. It is isotonic and does not cause hemolysis or alter the structure of red blood cells.
B. Lactated Ringers solution: Lactated Ringers solution is not used with blood products due to the potential for hemolysis when calcium is present, which can interfere with the clotting cascade and affect blood cell integrity.
C. 5% dextrose/0.2% sodium chloride: Dextrose solutions should not be used with blood components, as they can cause red blood cells to hemolyze, leading to hemolysis and complications in transfusion.
D. 5% dextrose/0.45% sodium chloride: This solution contains dextrose, which can cause red blood cell hemolysis and should not be used with blood products.

Correct Answer is C
Explanation
A. Lactulose: Lactulose is used to treat hepatic encephalopathy by reducing ammonia levels, not for hyperkalemia.
B. Acetylcysteine: Acetylcysteine is used for acetaminophen overdose or as a mucolytic agent, not for hyperkalemia.
C. Sodium polystyrene (Kayexalate): Kayexalate is used to treat hyperkalemia by exchanging sodium for potassium in the intestines, promoting the elimination of potassium through the stool. This is the correct treatment for a potassium level of 6.8 mEq/L, which is dangerously high.
D. Triamterene: Triamterene is a potassium-sparing diuretic and would worsen hyperkalemia, not treat it.
Correct Answer is A
Explanation
A. Potassium 2.5 mEq/L: This critically low potassium level can cause life-threatening cardiac dysrhythmias and requires immediate intervention.
B. Urine specific gravity 1.035: While indicative of dehydration, it is not life-threatening and can be addressed after correcting the potassium imbalance.
C. Weight loss of 3% of total body weight: Significant but not the most critical concern in the immediate term.
D. Blood glucose 150 mg/dL: Elevated but not urgent compared to the hypokalemia.
