Donation of patient's own blood prior to his scheduled surgery is?

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2016

Explanation

Autologous donation refers to the process where a patient donates their own blood for their own future use.
The prefix 'auto-' means 'self', making 'autologous' the correct term for self-donation.
This method is commonly used before elective surgeries with a high potential for blood loss, known as Preoperative Autologous Donation (PAD).
It is the safest transfusion option as it eliminates the risk of transfusion-transmitted infections and immune reactions from donor blood.

Option B: Homologous (or allogeneic) donation involves blood from a different person of the same species, not the patient's own blood.
Option C: Monologous is not a recognized term in transfusion medicine. It is included as a distractor.
Option D: Heterologous (or xenogeneic) donation refers to transplantation between different species (e.g., animal to human), not blood transfusion within the same person. The option is also misspelled.

Clinical Relevance

Nursing practice connection: Use the key finding related to Terminology of Blood Transfusion to guide bedside assessment, documentation, and the next nursing action.
Nurses play a crucial role in managing autologous blood donations, including patient education about the process, scheduling donations, and administering iron supplements.
A critical nursing responsibility is ensuring meticulous labeling and identification of autologous blood units to prevent administration errors. The unit must be clearly marked for the specific patient and never enter the general blood supply.
What if? If a patient who planned for an autologous donation has an unexpected drop in hemoglobin below 11 g/dL before the final donation? The donation would be cancelled, and the surgical plan might be re-evaluated. The patient may still use the units already collected or require allogeneic blood if transfusion is necessary.

How to Approach the Question

First, identify the key phrase in the question: 'patient's own blood'.
Recognize that this implies a process of self-donation.
Analyze the prefixes of the options. 'Auto-' means self, 'homo-' means same (but implies another of the same species), and 'hetero-' means different.
Based on the prefix 'auto-', 'Autologous' is the most logical answer for self-donation.
Eliminate 'Homologous' as it refers to donation from another person.
Eliminate 'Heterologous' as it refers to donation from a different species.
