Situation tasks for verification of eventual level of knowledge.

1. A patient with ulcerous illness of 12-falling bowel which was complicated by bleeding acted in the surgical separation. A deficit VCB makes 35%. With the purpose of renewal of blood loss the shown blood transfusion. Which is needed minimum of laboratory researches and tests which hemotransfusion is impossible without?

2. Under surveillance of doctor in a manipulation cabinet the two trained nurses determine the blood types of four patients. For this purpose they on the white plates made of delft the ware with the proper marks inflicted on 2 series of standard wheys. The explored blood was well mixed up with the drops of standard wheys. Plates rocked and left min on 1-2, then rocked again. Not early than 3 min, in places, where agglutination was brought in on 1 drops of 0.9% solution sodium of chloride. Through 5 min from the beginning of research a doctor conducted estimation of results, writing down them in a hospital chart. What a doctor did not paid attention on, violating the same the requirements „Instructions on determination of blood types on the system ABO”?

3. Patient with the massive internal bleeding on to the vital shows is taken in an operating-room. Under endotracheal anesthesia the operative interference directed on the eventual stop of bleeding is executed. With the purpose of renewal of blood loss during the operation there was a necessity in blood transfusion. How to conduct a biological test on compatibility to the patient, that is found under anesthesia?

4. During conducting of test on group compatibility the got agglutination. What must be executed and what this reaction indicates on?

5. At a recipient Rh-factor was determined by an express-method. During conducting of test on Rh-compatibility the got agglutination. What this reaction indicates on and that it is necessary to execute?

6. To the patient with the massive gastric bleeding (Hb 48 g/l, red corpuscles 1,8*10¹²/l, Ht 20% transfusion of red corpuscles mass is shown. Same blood red corpuscles mass is delivered from the station of transfusion to the blood. During conducting of test on compatibility on the system ABO there was agglutination. What this reaction indicates on? What must be done by a doctor?

7. To the patient that prepares to operative interference concerning the gastro-intestinal bleeding the trained nurse defined a blood type by the wheys of one series and showed to the doctor. Agglutination arose up with the whey of the first and third group. What blood type at a patient and whether a medical sister assumed an error?

8. Determination of blood type by standard wheys was conducted in plate at a temperature 14 ^oC. At determination of result there was agglutination with all wheys. How possible to interpret a research result?

9. Determination of blood type by standard wheys was conducted in plate at a temperature 35 ^oC. At determination of result agglutination in wheys did not arise up. Is it possible to interpret a research result as the first blood type?

10. At a patient with the internal peritoneum bleeding the trained nurse determines a blood type by means Coliclon. Agglutination arose up with Coliclon anti A also anti B. Is it possible to interpret result as blood type AB (ІV)?

11. At research of blood type by two series of standard wheys agglutination did not arise up through 3 min. A result interprets by a doctor, how the first blood type is. How right interpreting result?

12. At research of blood types by two series of standard wheys a research result was estimated by a doctor through 10 min. Agglutination happened in wheys O (І), A (ІІ), B (ІІІ). A result interprets, how a fourth blood type is. How is research correctly conducted?

13. During conducting of test on group compatibility on the system ABO to mix up the whey of donor with the red corpuscles of recipient. Estimated a research result it is not exposed through 5 min agglutinations. Does mean it, that blood of donor and recipient compatible on the system ABO?

14. During conducting of test on Rh-compatibility in a test tube a 1 drop of red corpuscles of donor, which before it washed 0.9% NaCl solution, was placed, 2 drops 10 were added % solution of gelatin and 2-3 drops of whey of recipient. The table of contents of test tube was mixed up. Estimated the result of test through 10 min, added in the test tube of a 5-8 ml 0.9% NaCl solution. Agglutination in a test tube is not exposed. Does testify it to that blood compatible on Rh-factor?

15. To the patient with the knife wound in a stomach and bleeding before the operation a blood type was determined by two series of standard wheys with the title of antibodies 1:32, with the term of good, that ended a 1 month ago. At estimation of agglutination it is not exposed in wheys O (І), A (ІІ), B (ІІІ) blood types. Does testify it to that at a patient the first blood type?
