A nurse is analyzing the arterial blood gas (ABG) results of a patient.


The patient’s ABGs are: pH:7.6, PaCO2:40 mm Hg, HCO3:32 mEq/L. Which of the following acid-base conditions should the nurse identify the patient is experiencing?

Choice A rationale:

Bilateral flank pain is not a typical sign of an allergic blood transfusion reaction. It can be associated with other conditions, such as kidney problems, musculoskeletal issues, or abdominal aortic aneurysm. While it's important to assess flank pain, it doesn't directly suggest an allergic reaction to the transfusion.

Choice B Rationale:

Distended jugular veins can indicate fluid overload, which could potentially occur during a transfusion. However, it's not a specific sign of an allergic reaction. Fluid overload can result from various causes, including heart failure, kidney problems, or excessive fluid intake. It's crucial to monitor for fluid overload during transfusions, but it doesn't definitively point to an allergic reaction.

Choice C Rationale:

Generalized urticaria, or hives, is a hallmark sign of an allergic reaction. It's characterized by raised, red, itchy welts that can appear on various parts of the body. Hives can develop rapidly and spread extensively. During a blood transfusion, generalized urticaria strongly suggests that the patient's immune system is reacting to a component of the transfused blood, such as proteins or antibodies.

Choice D Rationale:

Blood pressure 184/92 mm Hg is elevated and could be concerning, but it's not specific to allergic reactions. High blood pressure can have various causes, including stress, pain, anxiety, or underlying hypertension. While monitoring blood pressure during transfusions is essential, it doesn't directly indicate an allergic reaction.

Choice A rationale:

Serosanguineous drainage is a mixture of blood serum and blood. It is typically thin and watery, with a pinkish or reddish hue.

It is common in the early stages of wound healing, as small blood vessels are injured and release their contents. However, it's not consistent with the yellow and thick drainage described in the question, making it an unlikely choice.

Choice B Rationale:

Serous drainage is clear and watery, composed primarily of blood plasma.

It's also common in the early stages of wound healing and is considered a normal part of the process. However, the clear and watery nature of serous drainage doesn't match the thick, yellow drainage described in the question, ruling out this option.

Choice C Rationale:

Sanguineous drainage is composed primarily of fresh blood.

It's often bright red and may be thick or thin, depending on the amount of bleeding. While sanguineous drainage can indicate a problem, it's typically associated with active bleeding or recent trauma. The yellow color of the drainage in the question makes this choice less likely.

Choice D Rationale:

Purulent drainage is a thick, yellow, green, or brown fluid that often has a foul odor.

It's a sign of infection, as it contains dead white blood cells, bacteria, and debris. The yellow and thick consistency of the drainage described in the question strongly suggests purulent drainage, making it the most likely answer.

Key Points:

The color, consistency, and odor of wound drainage can provide valuable clues about the healing process and potential complications.

Purulent drainage is a hallmark of infection and requires prompt attention.

Nurses play a crucial role in assessing wound drainage and reporting any concerns to the healthcare team.
