Answer to Question 1

A
African Americans do have the highest incidence of sickle cell disease. Iatrogenic blood disord-ers are brought on by medical treatment, such as bone marrow suppression. Iron, rather than folic acid, is directly related to hemoglobin synthesis; folic acid is related to RBC maturation. The older adult tends to bruise more due to the thinning of the skin and the increased fragility of the vessels; therefore, it is expected to see some bruising with these patients. Excessive bruising, however, in the older adult patient should be investigated.

Answer to Question 2

C
The patient with ataxia has experienced a loss of balance or poor coordination; therefore, placing the call light on this patient's right side and reminding her to call for help will best address her high risk for falling. Pureed foods and thickened liquids are necessary for the patient with dys-phagia, and a communication board would assist a patient with dysarthria or aphasia.
