A nurse is monitoring a patient who is receiving a blood transfusion.


Which of the following symptoms should the nurse report to the charge nurse as a sign of an allergic blood transfusion reaction?

Choice A rationale:

Irreversible shock is the final stage of shock, where the body's compensatory mechanisms have failed, and damage to vital organs is irreversible. This stage is characterized by:

Profound hypotension (systolic blood pressure persistently below 60 mmHg) Severely altered mental status (unresponsiveness or coma)

Widespread organ failure (kidney failure, liver failure, respiratory failure) Lack of response to aggressive fluid resuscitation and vasopressor therapy

The patient in the question does not exhibit all of these signs and symptoms, particularly the profound hypotension and irreversible organ failure. Therefore, irreversible shock is not the most likely stage.

Choice B rationale:

End-organ dysfunction is a stage of shock where inadequate tissue perfusion has begun to cause damage to vital organs. This stage is characterized by:

Hypotension that may respond to fluid resuscitation

Signs of organ dysfunction, such as decreased urine output, altered mental status, or respiratory distress

The patient in the question does have some signs of organ dysfunction, such as confusion and crackles on lung auscultation. However, the hypotension is not as severe as typically seen in end-organ dysfunction shock, and there is no mention of other organ dysfunction like decreased urine output. Therefore, end-organ dysfunction is not the most likely stage.

Choice C rationale:

Early reversible shock is the initial stage of shock, where the body's compensatory mechanisms are still able to maintain blood pressure and organ perfusion. This stage is characterized by:

Mild to moderate hypotension Tachycardia

Cool, clammy skin Narrowed pulse pressure Restlessness or anxiety

The patient in the question presents with all of these signs and symptoms, making early reversible shock the most likely stage.

Choice D rationale:

Preshock is a state of impending shock, where the body's compensatory mechanisms are activated but not yet fully effective. This stage is characterized by:

Normal or slightly low blood pressure Tachycardia

Cool, clammy skin Restlessness or anxiety

The patient in the question has hypotension, which is not consistent with preshock. Therefore, preshock is not the correct stage.

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.
