A nurse is caring for a client with severe anemia. The provider placed an order for one unit of packed red blood cells (PRBCs) x 1 now. The nurse should anticipate the blood will be completely infused after how much time?
8 hr
4 hr
6 hr
2 hr
The Correct Answer is D
A. 8 hr - Infusing one unit of packed red blood cells (PRBCs) over 8 hours is too long. Typically, PRBCs are infused over a shorter period to avoid complications.
B. 4 hr - Infusing PRBCs over 4 hours is still within acceptable limits, but the standard time for PRBC transfusion is usually shorter.
C. 6 hr - Infusing PRBCs over 6 hours is longer than usual. The recommended duration for infusing one unit of PRBCs is generally shorter.
D. 2 hr - The standard time to infuse one unit of PRBCs is typically between 1.5 to 2 hours. This duration helps ensure the effective delivery of red blood cells while minimizing the risk of transfusion reactions.

Correct Answer is D
Explanation
A) Isotonic solution: Isotonic solutions, such as 0.9% sodium chloride, maintain the current sodium levels and fluid balance but do not correct hypernatremia. They are not suitable for lowering elevated sodium levels.
B) Total Parenteral Nutrition (TPN): TPN is used for providing comprehensive nutritional support and does not address electrolyte imbalances such as hypernatremia. It is not used to manage sodium levels directly.
C) Hypertonic solution: Hypertonic solutions, such as 3% sodium chloride, increase sodium levels and are used for treating hyponatremia or specific conditions requiring higher sodium concentrations. They would worsen hypernatremia.
D) Hypotonic solution: Hypotonic solutions, like 0.45% sodium chloride (half-normal saline) or Dextrose 5% in water (D5W), are appropriate for treating hypernatremia. They help dilute the sodium concentration in the blood and aid in correcting the elevated sodium levels
