Answer: a. use of refrigerated clotted blood samples in which complement components coat RBCs in vitro
Explanation:
DAT is direct antiglobulin test. It is also called as Coombs test. It is primarily used for determining the cause of hemolytic anemia. This test looks for the attachment of the antibodies that break apart the red blood cells causing hemolysis.
A false positive DAT result signifies that the eluted antibody cannot bind to the red blood cells. But binding do occur in true positive test.
Thus the result may reflect that it has been conducted on the refrigerated and clotted blood samples yielding a false result in inappropriate results.

Answer:
Shortness of breath at the least effort
Explanation:
Left heart failure causes fluid to accumulate in the lungs and consequently shortness of breath. Initially, shortness of breath occurs only during exertion, but as heart failure progresses, shortness of breath begins to occur with less effort and finally even at rest. People with severe left heart failure may feel short of breath when lying down as gravity causes more fluid to enter the lungs. These people often wake up panting or wheezing (a clinical condition called paroxysmal nocturnal dyspnea). When sitting, some of the fluid is drained to the lower lungs, which makes breathing easier. People with left heart failure feel tired and weak during physical activity because their muscles are not getting enough blood.
A client diagnosed with left-sided heart failure should be taught to recognize this sign and receive guidance on postures to be taken to improve the condition and in case of no improvement seek a hospital.
