A nurse is planning care for a client who is to receive one unit of packed RBCs. Within which of the following time spans must the nurse complete the infusion?
2 hr
8 hr
6 hr
4 hr
The Correct Answer is D
A. 2 hr: While some patients may tolerate faster infusion rates, the maximum safe time is 4 hours, and there is no requirement to complete it in 2 hours.
B. 8 hr: Blood cannot be left out for 8 hours due to the increased risk of bacterial growth and contamination.
C. 6 hr: Infusing blood over 6 hours exceeds the safe time limit and poses a risk of bacterial contamination.
D. 4 hr: To reduce the risk of bacterial contamination, a unit of packed RBCs must be transfused within 4 hours of starting the infusion. This time frame ensures that the blood remains safe for the patient while minimizing exposure to room temperature.

Correct Answer is B
Explanation
A. Initiate a 2 L/day fluid restriction: Hydration is crucial in sickle cell crisis to prevent further sickling and reduce blood viscosity. A fluid restriction would worsen the crisis.
B. Assist with administering a blood transfusion: Blood transfusions are commonly given during sickle cell crisis to manage anemia and reduce the concentration of sickled cells, which can improve oxygen delivery and relieve pain.
C. Withhold opioids to avoid dependence: Pain management, including opioids if needed, is essential during a sickle cell crisis. The risk of dependence is secondary to controlling acute pain.
D. Encourage exercise: Rest is recommended during a crisis to reduce oxygen demand and prevent further sickling. Exercise would increase oxygen needs, worsening the crisis.
Correct Answer is D
Explanation
A. Pulmonary congestion: Pulmonary congestion is associated more with fluid overload or transfusion-associated circulatory overload (TACO), not an acute hemolytic reaction.
B. Urticaria: Urticaria (hives) is more typical of a mild allergic reaction rather than an acute hemolytic reaction.
C. Vomiting: Although nausea and vomiting may occur in various transfusion reactions, it is not specific to an acute hemolytic reaction like low back pain is.
D. Low back pain: Low back pain, often around the kidneys, is a classic sign of an acute hemolytic reaction due to the breakdown of RBCs and the release of hemoglobin into the bloodstream, which can lead to renal damage. This reaction is a medical emergency requiring immediate intervention.
