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 A
Explanation
A. Urine specific gravity 1.034: High urine specific gravity (greater than 1.030) indicates concentrated urine, which is a sign of dehydration. This suggests the kidneys are conserving water due to a lack of fluid.
B. Distended neck veins: Distended neck veins usually indicate fluid overload or hypervolemia, not dehydration.
C. BP 146/94 mm Hg: While elevated blood pressure could be a sign of various conditions, it is not a typical indicator of dehydration. Dehydration often leads to low blood pressure.
D. Bounding pulse: A bounding pulse is often associated with fluid overload or fever and does not indicate dehydration. In dehydration, the pulse may be weak or thready.
Correct Answer is B
Explanation
A. Dextrose 10% in water: Dextrose solutions provide calories but do not restore volume or replace electrolytes. They are not typically used in hypovolemic shock.
B. Lactated Ringer's: Lactated Ringer’s solution is an isotonic solution containing sodium, potassium, calcium, and lactate, which helps restore both fluid volume and electrolytes in the case of hypovolemic shock. It is commonly used while awaiting blood transfusions.
C. 0.33% sodium chloride: This is a hypotonic solution that can cause fluid to shift into cells and is not appropriate for fluid resuscitation in hypovolemia, which requires an isotonic solution.
D. 0.45% sodium chloride: This is a hypotonic solution as well, and it could worsen hypotension by causing fluid shifts into the cells, which is not ideal for treating hypovolemic shock.
