A nurse is caring for a client who has heart failure.
Which of the following manifestations should the nurse expect?

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:

Taking ibuprofen during pregnancy is generally not recommended, especially in high doses or for an extended period, as it can increase the risk of complications, including heart defects in the baby. Therefore, advising the client to take 600 milligrams of ibuprofen every 8 hours is not appropriate and potentially harmful during pregnancy.

Choice B rationale:

Having a cesarean birth (C-section) is recommended if there are visible lesions of genital herpes during labor and delivery. This precautionary measure helps prevent the transmission of the herpes simplex virus (HSV) from the mother to the baby, reducing the risk of neonatal herpes infection, which can be severe or even life-threatening.

Choice C rationale:

Testing the baby's cord blood for HSV is not a standard practice. Instead, if there are visible lesions or symptoms of herpes during labor, a C-section is often performed to minimize the risk of transmission. Testing the baby after birth may be done if there are concerns about potential exposure.

Choice D rationale:

Applying a cortisone cream to the lesions is not recommended without medical supervision during pregnancy. Topical corticosteroids, such as cortisone creams, can be absorbed through the skin and may have adverse effects on both the mother and the baby. It is essential to consult a healthcare provider before using any medications or creams during pregnancy to ensure safety for both the mother and the baby.
