Mrs. Jones blood typing results showed agglutination with the plasma containing anti - B antibodies only. What is her blood type
MakcuM [25]

Answer:

Mrs Jones Blood type= B type.

Safe transfusion from: B and O blood type.

Explanation:

In the given example, the anti-B antibodies are present in the donor plasma.  Since anti-B antibodies react with B antigen present on the RBCs of blood, Mrs. Jones should have B antigen on the surface of her RBCs. The blood type with only B-antigen on the RBC's surface is blood type "B".  

Hence, her blood type is "B" type which has B antigens that react with anti B antibodies of the donor plasma causing agglutination and hemolysis of RBCs.  

She can get the blood of B and O blood types. Blood type O is a universal blood type as it does not have B or A antigens on the surface of its RBCs to initiate the agglutination.

Oxana [17]

Answer:

The options

"The delegatee should report the findings back to the delegator."

"The delegatee should understand the assigned task completely."

"The delegator should trust the delegatee to accomplish the task."

"The delegator should recheck and redo the work of the delegatee."

The CORRECT ANSWER IS

"The delegator should recheck and redo the work of the delegatee.

Explanation:

An effective leader must learn to effectively delegate tasks by appropriating the tasks based on skill and talent of his/her members in order to increase productivity and accuracy.

"The delegator should recheck and redo the work of the delegatee."✔

Time management is a necessary factor in delegation processes. If the delegator needs to rechecks and redoes the task assigned to the delegatee, it consumes time needed for other tasks and slows the process of achieving the task and results due to inappropriate delegation.

"The delegatee should report the findings back to the delegator."❌

Reporting the results after it's being carried out to the delegator would give the delegator a clear view on how the process of the task is going.

"The delegatee should understand the assigned task completely."❌

The delegatee needs to comprehend the task completely to perform to details as instructed by the delegator.

"The delegator should trust the delegatee to accomplish the task."❌

Trusting the delegatee decrease the time to get it done and promote a healthy working atmosphere.
