Providone- iodine

Which of the following infections, agents relies solely on donor questioning to avoid transmission from transfused blood products ?

Plasmodium falciparum

There is no current test to detect the presence of plasmodium Parasites in Blood donors. Protection from transfusion, transmitted malaria rely solely on ascertaining the travel history of prospective donors

Which of the following practices at the time of blood collections helps minimize bacterial contamination of platelet products

diversion pouch

Diversion of the first 10 to 40 ML of Donor blood that may contain contaminated skin into a separate pouch help prevent bacterial contamination and blood products particularly true platelet products as a storage of 2O-24 Celsius can facilitate bacteria growth

If a unit of autologous Red blood cells is collected and transfers in the same facility which of the following is not required

Infections disease screening

If the collecting in interest using facilities are the same infection or disease screening is not required ABO and RH testing must be done for each autoglous Donation. A physicians order and evaluation for potential infection, and the autologous are also required

According to the AABB standards what is the minimum hemoglobin level for an autologous Donor

11.O g /gl

Which of the following must include on the label of the unit red blood cells leukocytes reduced

Unique collection facility identifier

The label on any blood products must include the unique facility identifier, such as the FDA registration number and facility name

Allblood donor testing must include

Serological test for Syphilis

Testing for syphilis Was the first mandated Donor screening test for infection disease and is still part of infection disease testing

Which of the following is not a useful strategy to reduce bacterial contamination and platelet components

Using green soap scrub to disinfect venipuncture site

Which of the following practices has been useful and reducing the incident of transfusion related acute lung injury

Use of fresh frozen plasma from male donors

In allogeneic blood donation, which of the following infectious agents must also include a nuclear acid test (NAT) assay

HBV

What is the primary reason that infection is agents can be transmitted following blood transfusions

Donor in the window period of early infection.

Apheresis platelets that will undergo pathogen reduction technology do not require

Culture base testing for bacteria

Which of the following courses of action must be performed immediately if a sample from an apheresis completely undergoing culture based testing indicates bacteria growth?

Retrieve the unit if issued for transfusion

Platelets components undergo culture based testing for detection of bacteria are usually released to inventory as incubation of those cultural continues if a culture becomes positive. The first action is to retrieve products issue from the inventory as they may not have been transfused this retrieval can prevent an adverse reaction in a blood recipient

A sample of blood from each donation is tested for which of the following infection diseases

HIV ½ , HTLV-l/ll, WNV, HCV

1-10 c

The transport temperature for apheresis Platelets is

20-24 c

A unit of red blood cells Expiring in 35 days is split Into 5 Small aliquots Using a sterile, pediatric quad set and a sterile connecting device. Each aliquot must be labeled as expiring in

35 days

Sterile connecting devices, allow entry and donor units without affecting the expiration date of the product

When platelets are stored on a rotator set on an open bench top that ambient air temperature must be recorded

Every 4 hours

Which of the following is a correct storage temperature for the component listed?

Fresh frozen plasma is stored at -18 c For 12 months

Six units of red blood cells are issued to the OR at 9 AM in a cooler validated to maintain a temperature of 1-10 For 2 hours. The cooler containing the units of blood is returned to the blood bank 40 minutes later because surgery is canceled. What should be done with these units?.

Inspect the units and established the appropriate temperature has been maintained.

** Blood may be returned to the blood bank after issue provided that the container closure has not been distribute at least once sealed segment is attached to the container. Visual inspection of the unit is satisfactory and documented, and the unit has been maintained at appropriate storage or transport temperature.

If the seal is entered or broken on a unit of a red blood cell stored at 1-6 c What is the maximum allowable storage period in hours?
