A nurse is caring for a client in acute respiratory failure who is receiving mechanical ventilation. Which of the following assessments is the best method to determine the effectiveness of the current treatments?

Choice A reason:

A serum blood glucose level of 128 mg/dL is slightly elevated but not immediately concerning in the context of organ donation. Blood glucose levels can be managed with insulin if necessary, and this value does not indicate an acute issue requiring immediate intervention.

Choice B reason:

A blood pressure of 83/51 mmHg is critically low and requires immediate action. Low blood pressure can compromise organ perfusion and oxygen delivery, potentially leading to organ damage. In the context of organ donation, maintaining adequate perfusion pressure is essential to ensure the viability of the organs for transplantation.

Choice C reason:

A hemoglobin level of 13 g/dL is within the normal range and does not require immediate intervention. Hemoglobin levels are important for oxygen-carrying capacity but are not the priority concern six hours before organ harvesting if the value is within normal limits.

Choice D reason:

A core body temperature of 97.8 degrees F is slightly below normal but not immediately alarming. Mild hypothermia can be addressed with warming measures, and this temperature does not indicate a critical issue that requires urgent action.

Choice A reason:

Administering Heparin to a patient who is already taking Warfarin and experiencing rectal bleeding is not appropriate. Heparin is an anticoagulant, similar to Warfarin, and would not help in reversing the anticoagulant effects of Warfarin. Instead, it could potentially exacerbate the bleeding.

Choice B reason:

Vitamin K is the correct answer because it acts as an antidote to Warfarin. Warfarin works by inhibiting the synthesis of Vitamin K-dependent clotting factors, so administering Vitamin K helps to reverse the effects of Warfarin and promote blood clotting, which is necessary to control the rectal bleeding in this patient.

Choice C reason:

Iron is not the appropriate treatment for rectal bleeding due to Warfarin. While iron supplements can help with anemia (which might result from chronic blood loss), they do not address the immediate need to reverse the anticoagulant effects of Warfarin and stop the active bleeding.

Choice D reason:

Protamine is used to reverse the effects of Heparin, not Warfarin. Therefore, administering Protamine would not be effective in addressing the Warfarin-induced rectal bleeding in this patient.
