Answer to Question 1

ANS: D
Other abnormal hemoglobins migrate with Hb S on alkaline hemoglobin electrophoresis; Hb D is an example. However, these hemoglobins are not sickling hemoglobins. Therefore a positive tube solubility test would confirm that the hemoglobin in the S position is Hb S.

Answer to Question 2

ANS: D
Hb S forms insoluble polymers when the oxygen saturation is low. Thus this would precipitate sickling, not improve the outcome of sickle cell anemia. All the other therapies mentioned have been shown to be clinically helpful.

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
