A nurse is planning care for a client who is scheduled to receive a transfusion of packed RBCs.
Which of the following actions should the nurse plan to take?
Store the unit of blood at room temperature for 1 hr prior to the infusion.
Ensure that the transfusion is completed within 6 hr.
Obtain venous access using a 22-gauge needle.
Use a solution of 0.9% sodium chloride to flush the transfusion tubing.
The Correct Answer is D
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.

Correct Answer is A
Explanation
Choice A rationale:
The described cardiac rhythm with a wavy baseline, no distinguishable P waves, and an increased heart rate is consistent with atrial fibrillation. In atrial fibrillation, the atria quiver instead of contracting effectively, leading to an irregular and often rapid heart rate. This rhythm is characterized by the absence of distinct P waves on the ECG.
Choice B rationale:
Ventricular asystole is a flatline on the ECG, indicating the absence of electrical activity in the heart. It is a life-threatening arrhythmia and requires immediate intervention with cardiopulmonary resuscitation (CPR) and advanced cardiac life support (ACLS) protocols.
Choice C rationale:
Second-degree heart block is characterized by intermittent failure of atrial electrical impulses to conduct to the ventricles. This results in occasional dropped beats and a varying heart rate. It is not consistent with the described ECG findings in the question.
Choice D rationale:
Sinus tachycardia is a regular, fast heart rate originating from the sinoatrial (SA) node. In sinus tachycardia, P waves are present, indicating that the electrical impulses originate in the SA node. The described ECG findings do not match the characteristics of sinus tachycardia.
Correct Answer is A
Explanation
Choice A rationale:
"Since I retired, I have entered many gardening competitions." This statement indicates compensation as a defense mechanism. Compensation involves emphasizing personal strengths in one area to shift focus from failure or weakness in another. In this case, the client is finding fulfillment and recognition in gardening competitions after retiring, compensating for the loss of work-related identity.
Choice B rationale:
Expressing relief about retirement due to negative work experiences doesn’t necessarily indicate compensation. It could be a coping mechanism, but it doesn't align with the compensation defense mechanism, which involves overachieving in one area to compensate for deficiencies in another.
Choice C rationale:
Choice D rationale:
Journaling about career accomplishments after layoffs indicates sublimation, not compensation. Sublimation is a defense mechanism where unacceptable impulses or behaviors are transformed into socially acceptable actions or pursuits, like channeling frustration or disappointment into creative or productive activities such as journaling.
