A nurse is planning care for a client who is to receive packed RBCs. The nurse should plan for the total infusion time to not exceed which of the following?
1 hour
2 hours
3 hours
4 hours
The Correct Answer is D
Choice A reason: Infusing packed RBCs over 1 hour is typically too rapid for most patients and can increase the risk of adverse reactions, especially in those with cardiovascular compromise.
Choice B reason: A 2hour infusion may be appropriate in certain emergency situations where rapid correction of anemia is required, but it is not the standard practice for routine transfusions.
Choice C reason: A 3hour infusion is less commonly used and does not provide any specific advantage over the standard 4hour infusion time.
Choice D reason: The standard practice is to complete the transfusion of packed RBCs within 4 hours. This duration minimizes the risk of bacterial growth and transfusion reactions, as recommended by the American Society of Hematology and other clinical guidelines.

Correct Answer is C
Explanation
Choice A reason: This is incorrect. While gentle hair care is important, it is not as critical as sun protection for SLE patients.
Choice B reason: This is incorrect. Powder can be drying, and SLE patients often need to keep their skin moisturized.
Choice C reason: This is correct. SLE patients are often photosensitive and need to protect their skin from UV rays.
Choice D reason: This is incorrect. SLE patients should keep their skin well moisturized to prevent dryness.
Correct Answer is B
Explanation
Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.
Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.
Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.
Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.
