- How does hydroxyurea therapy alleviate the symptoms of sickle cell anemia? (Select all that apply.) HbS dilutes HbF and thus somewhat relieves the symptoms of the disease. HbF dilutes HbS and thus somewhat relieves the symptoms of the disease. HbF, because of its amino acid sequence, does not sickle and clog capillaries. O Hydroxyurea enhances the production of sickle-cell hemoglobin (HbS) in the bone marrow. Hydroxyurea enhances the production of fetal hemoglobin (HbF) in the bone marrow. O HbS, because of its amino acid sequence, does not sickle and clog capillaries.F2 over the arrow connecting these variables. The slope of this relationship is 0.225 mmHg/(L/min). In the absence of the drug, Xor's blood pressure would drop as low as 70 mmHg. As the blood pressure falls to 70 mm Hg, how much drug should we administer to restore the blood pressure to 105 mmH? To answer this question, assume the following conditions: 1. the drug directly affects the rate of blood flow from the heart (L/min), 2. the drug has no effect at dosages below 41 g and has a linear effect on the rate of blood flow at dosages above 41 g. The slope of this linear effect is 2.91 (L/min) / g of drug, and 3. the drug must increase the rate of blood flow enough to increase the blood pressure from 70 mm Hg to 105 mmHg, and 4. the slope of the linear relationship between the rate of blood flow from the heart and the blood pressure in megaraffes is 0.225 mmHg/(L/min). Our goal is to determine the dosage of the drug needed to increase the blood pressure by 35 mmHg. We'll work backwards…The instructions for the azithromycin state to reconstitute the 600 mg vial with 3.6 mL until dissolved, to yield a strength of 150 mg/mL, and then to add it to 270 mL of D5W and administer over at least 60 minutes.
