A nurse is caring for a patient with hypoxia due to anemia and is exploring treatment options to improve oxygen-carrying capacity.
What therapy can the nurse recommend?
"I suggest volume expanders like lactated Ringer's to increase your blood volume and circulation.”
"You may benefit from hemostatic agents such as protamine sulfate to stop bleeding.”
"Consider oxygen therapy delivered through a nasal cannula or mask to enhance your oxygen-carrying capacity.”
"Erythropoietin injections can stimulate the production of red blood cells and help alleviate your hypoxia.”
The Correct Answer is D
Choice A rationale:
Lactated Ringer's solution is a volume expander, not a therapy for improving oxygen-carrying capacity.
It can increase blood volume but does not address the underlying cause of anemia or hypoxia.
Choice B rationale:
Hemostatic agents like protamine sulfate are used to reverse the anticoagulant effects of heparin.
They are not indicated for improving oxygen-carrying capacity in anemic patients.
Choice C rationale:
Oxygen therapy delivered through a nasal cannula or mask is indeed a therapy to enhance oxygen-carrying capacity.
It provides supplemental oxygen to improve oxygen saturation in the blood, which can alleviate hypoxia in anemic patients.
Choice D rationale:
Erythropoietin injections can stimulate the production of red blood cells in the bone marrow.
This therapy can increase the patient's hemoglobin levels and improve oxygen-carrying capacity, making it a suitable recommendation for a patient with hypoxia due to anemia.
For , choices A, C, and D are correct as they are examples of volume expanders that can increase blood volume and circulation without adding blood cells.
For , choice C is correct as hemostatic agents like vitamin K or tranexamic acid can promote clotting and stop bleeding in a patient with a bleeding disorder.
For , choice D is correct as erythropoietin injections can stimulate the production of red blood cells and help alleviate hypoxia in a patient with anemia.

Correct Answer is A
Explanation
Choice A rationale:
Whole blood.
Rationale: Whole blood contains all blood components, including red blood cells, plasma, platelets, and clotting factors.
It is used for patients with symptomatic anemia and ongoing bleeding, as it can address both the anemia and provide clotting factors to assist in hemostasis.
Choice B rationale:
Packed red blood cells (PRBCs)
Rationale: Packed red blood cells are primarily used to increase the oxygen-carrying capacity in patients with anemia or significant blood loss.
While they can address the anemia component of the patient's condition, they do not provide clotting factors.
Therefore, they may not be the best choice for patients with ongoing bleeding.
Choice C rationale:
Fresh frozen plasma (FFP)
Rationale: Fresh frozen plasma is rich in clotting factors and is used to treat bleeding disorders or clotting factor deficiencies.
It can be beneficial for patients with bleeding issues but does not address the anemia component of the patient's condition.
Choice D rationale:
Platelets.
Rationale: Platelets are responsible for clot formation and are primarily used to treat thrombocytopenia or clotting disorders.
They do not address the anemia component of the patient's condition and are not typically considered an alternative to blood transfusion for anemic patients with ongoing bleeding.
ABO and Rh Blood Group Systems:
Correct Answer is A
Explanation
Choice A rationale:
Autologous transfusion involves collecting and storing the patient's blood before a planned surgery or procedure, eliminating the risk of incompatibility, infection, and immunologic reactions associated with allogeneic (donor) blood transfusions.
This option aligns with the patient's religious beliefs and offers a safe alternative.
Choice B rationale:
Erythropoietin therapy stimulates red blood cell production but does not eliminate the need for transfusion entirely.
It may not align with the patient's refusal of blood products due to religious beliefs.
Choice C rationale:
Iron therapy can increase hemoglobin levels but may not completely eliminate the need for transfusion.
It also may not be a suitable alternative for the patient's specific condition.
Choice D rationale:
Hemostatic agents are not a substitute for blood transfusion.
They are used to control bleeding but do not address anemia or increase hemoglobin levels.
