The client has an IV of dextrose 5% in 0.45% normal saline. The physician has ordered a transfusion of one unit of packed red blood cells (PRBCs).
Before hanging the blood, the nurse will prime the blood tubing with which of the following solutions?
0.9% sodium chloride.
Lactated Ringer's.
5% dextrose.
5% dextrose in 0.45% sodium chloride.
5% dextrose in 0.45% sodium chloride.
The Correct Answer is A
This is the only solution that is isotonic and compatible with blood products. It will not cause hemolysis or clotting of the blood cells.
Choice B is wrong because lactated Ringer’s is a balanced electrolyte solution that contains calcium, which can cause clotting of the blood cells.
Choice C is wrong because 5% dextrose is a hypotonic solution that can cause hemolysis of the blood cells.
Choice D is wrong because 5% dextrose in 0.45% sodium chloride is a hypertonic solution that can cause hemolysis of the blood cells.

Correct Answer is B
Explanation
Uremia is a condition where there is an excess of urea and other nitrogenous wastes in the blood, usually excreted by the kidneys into the urine. It occurs when the kidneys stop filtering toxins out through your urine and can be a sign of end-stage renal (kidney) disease.
Choice A is wrong because azotemia is the buildup of nitrogen waste products in the blood, not urea.
Choice C is wrong because anuria is the absence or reduction of urine output.
Choice D is wrong because oliguria is the low output of urine.
Correct Answer is B
Explanation
This is because hyperkalemia is a condition where the blood potassium level is too high.
This can cause cardiac arrhythmias, muscle weakness, and paralysis. Therefore, the nurse should administer intravenous insulin and glucose to lower the blood potassium level by shifting it into the cells.
Choice A is wrong because encouraging the patient to consume a high- potassium diet would increase the blood potassium level and worsen the condition.
Choice C is wrong because administering a potassium-sparing diuretic would prevent the excretion of excess potassium and aggravate the hyperkalemia.
Choice D is wrong because encouraging the patient to limit fluid intake is not relevant to the management of hyperkalemia and may cause dehydration.
