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 A
Explanation
Choice A reason: Weight bearing exercises, such as walking, jogging, and dancing, are beneficial for building and maintaining bone density. These activities force the body to work against gravity, stimulating bone formation and slowing bone loss.
Choice B reason: While bone density scans are useful for diagnosing osteoporosis, they are not typically used as a preventive measure but rather as a diagnostic tool to assess bone health.
Choice C reason: Drinking coffee in moderation is not directly related to preventing osteoporosis. Excessive caffeine intake can interfere with calcium absorption, but a single cup is unlikely to have a significant impact.
Choice D reason: Increasing sodium intake is not recommended as it can lead to calcium loss through urine, which is counterproductive for bone health.
Correct Answer is C
Explanation
Choice A reason: Acute pain is expected with a fracture but does not specifically indicate impaired venous return.
Choice B reason: Ecchymosis, or bruising, can occur with a fracture due to bleeding into the tissue but is not a direct indicator of venous return issues.
Choice C reason: Increasing edema is a sign of impaired venous return as it indicates a buildup of fluid in the tissues, which can occur if the veins are not effectively returning blood to the heart.
Choice D reason: A diminishing distal pulse could indicate arterial impairment rather than venous return issues.
