A nurse is assessing a client following an esophagogastroduodenoscopy.
Which of the following findings should the nurse report to the provider?

The correct answer is D. Use a solution of 0.9% sodium chloride to flush the transfusion tubing.

Choice A reason: Storing a unit of blood at room temperature for 1 hour prior to the infusion is not recommended. Blood products should be kept refrigerated until just before the transfusion to minimize the risk of bacterial contamination. The recommended storage temperature for packed RBCs is 1-6°C. If blood is left at room temperature, it should be infused within 30 minutes to ensure safety.

Choice B reason: Ensuring that the transfusion is completed within 6 hours is not correct. The standard practice is to complete a blood transfusion over 2 to 4 hours, depending on the volume and the patient’s condition. This is to reduce the risk of bacterial growth and transfusion reactions. Prolonging the transfusion time beyond 4 hours increases the risk of bacterial contamination and can compromise the efficacy of the transfused red blood cells.

Choice C reason: Obtaining venous access using a 22-gauge needle is not ideal for a transfusion of packed RBCs. A larger bore needle, typically an 18-gauge or 20-gauge, is preferred to ensure adequate flow of the viscous packed RBCs and to prevent hemolysis. The smaller the gauge number, the larger the needle diameter, so a 22-gauge needle might be too small and could damage the red blood cells during the transfusion.

Choice D reason: Using a solution of 0.9% sodium chloride to flush the transfusion tubing is the correct action. Normal saline is isotonic and is the only fluid compatible with packed RBCs. It is used to prime the transfusion set and to flush the line before and after the transfusion to prevent hemolysis and clotting within the tubing.

Choice A rationale:

Sitting in high-Fowler's position during the feeding is actually a preventive measure against aspiration. High-Fowler's position, which involves sitting the patient upright at a 90-degree angle, reduces the risk of aspiration by promoting proper digestion and preventing the regurgitation of gastric contents into the lungs.

Choice B rationale:

A history of gastroesophageal reflux disease (GERD) puts the client at risk for aspiration. GERD is a chronic condition in which stomach acid frequently flows back into the esophagus, potentially reaching the throat and lungs, increasing the risk of aspiration during enteral feedings. Aspiration pneumonia, a serious complication, can develop if stomach contents enter the lungs.

Choice C rationale:

A residual of 65 mL 1 hr postprandial indicates that a significant amount of the feeding solution has not been absorbed, raising concerns about delayed gastric emptying. While this situation might require monitoring and adjustments to the feeding regimen, it does not directly increase the risk of aspiration. Aspiration risk is more related to the reflux of stomach contents into the airways.

Choice D rationale:

Receiving a high-osmolarity formula alone does not directly increase the risk of aspiration. High-osmolarity formulas might require careful administration and monitoring to prevent complications, but aspiration risk is more closely associated with the client's underlying conditions, such as GERD.
