What does SHOT stand for? Serious Hazards of TRALI Serious Hazards of Transfusion Serious Harms of Transfusion Some Hotels Offer Training

Where do the majority of errors occur? In the laboratory Removing blood from the blood fridge At the bedside In the ward manager’s fridge

What minimum identifiers are required on a transfusion sample? Full Name, date of birth and hospital number/NHS number Name and date of birthHospital number, date of birth and address Date of birth and hospital number

Transfusion samples have to be: Collected by the Doctor and labelled by the Nurse at the site of collection Collected and labelled by the same person at the site of collection Collected and labelled by the same person from the case notes Collected and labelled by the same person at the Nursing station

“Labelling of sample” errors usually happen because: The request form was not checked correctly The patient identification was not checked The patient was awkward The patient had somebody else’s wristband on

For routine transfusions, how many units can be sent from the Blood Bank fridge at one time? 3 units 2 units As many as you want 1 unit

Indications codes are used in transfusion to: Prescribe blood Order blood Request a group and save test Collect blood

Platelet concentrates should be ordered for bone marrow failure, in the absence of bleeding, when the platelet count falls below: < 50 x 10 9 /L < 10 x 10 9 /L < 30 x 10 9 /L >20 x 10 9 /L

In bone marrow failure, to prevent bleeding associated with invasive procedures “eg insertion of intravenous lines”, the platelet count should be raised to: > 20 x 10 9 /L > 50 x 10 9 /L > 100 x 10 9 /L > 30 x 10 9 /L

What are the minimum blood observations necessary when transfusing a patient? Start (Baseline), finish and 15 minutes into the transfusion Hourly Every 30 minutes Start (baseline), finish and 45 minutes into the transfusion

In bone marrow failure to prevent bleeding associated with surgery to brain or eyes the platelet count should be raised to: > 50 x 10 9/L > 100 x 10 9 /L > 30 x 10 9 /L >20 x 10 9/L

In massive transfusion the aim is to maintain the platelet count: > 20 x 10 9 /L > 50 x 10 9/L > 100 x 10 9 /L > 30 x 10 9 /L

In Neonatal Allo-Immune Thrombocytopenia for bleeding or as prophylaxis treatment the platelet count should be: > 20 x 10 9 /L > 50 x 10 9/L > 100 x 10 9 /L > 30 x 10 9 /L

One therapeutic dose of platelets is equivalent to: 10 ml/kg body weight 25 ml/kg body weight 5 ml/kg body weight 15 ml/kg body weight

FFP should be used for the immediate reversal of the Warfarin effect: When the INR is 1.3 When the INR is slightly raised When the INR is 6.0 In the presence of life threatening bleeding

To determine how much FFP is required for your patient you should: Calculate the amount required using the formula 15 ml/kg body weight Order 2 packs of FFP Order 4 packs of FFP Calculate the amount required using the formula 10 ml/kg body weight

Cryoprecipitate is indicated in: DIC where there is bleeding and a fibrinogen level >2.1g/L DIC where there is bleeding and a fibrinogen level >1g/L DIC where there is bleeding and a fibrinogen level <1g/L DIC where there is bleeding and a fibrinogen level <0.1g/L

Cryoprecipitate is now supplied by the NBS in single units and in: Double units Pools of 10 units Pools of 15 units Pools of 5 units

In adults, 2 pools of Cryoprecipitate are generally equivalent to: A therapeutic dose 2x a therapeutic dose Insufficient FVIII requirement Half a therapeutic dose

1 day post surgery, Hb of 7.5, patient not symptomatic, no significant risk factors: how many units of blood should be given? 3 units 2 Units None 1 unit

In chronic anaemia the patient should be transfused to: Maintain the Hb above 10.0 Maintain the Hb just above the concentration which is not associated with symptoms of anaemia Maintain the Hb above 12.0 Maintain the Hb above 9.0
