The major impact of the physiological changes that occur with aging is:
Reduced physiological reserve Reduced homeostatic mechanisms Impaired immunological response
Question 2.
Men have faster and more efficient biotransformation of drugs and this is thought to be due to:
Less obesity rates than women Prostate enlargement
Question 3.
The cytochrome p system involves enzymes that are generally:
Inhibited by drugs
Induced by drugs
Question 4.
Functional abilities are best assessed by:
Self-report of function
Question 5.
Iron Deficiency Anemia (IDA) is classified as a microcytic, hypochromic anemia. This classification refers to which of the following laboratory data?
Hemoglobin and Hematocrit
Question 6.
When interpreting laboratory data, you would expect to see the following in a patient with Anemia of Chronic Disease (ACD):
Hemoglobin <12 g/dl, MCV decreased, MCH decreased Hemoglobin >12 g/dl, MCV increased, MCH increased
Question 7.
The pathophysiological hallmark of ACD is:
Depleted iron stores
CORRECT Impaired ability to use iron stores
Chronic uncorrectable bleeding Reduced intestinal absorption of iron
Instructor Explanation: The pathophysiological hallmark of ACD is a disregulation of iron homeostasis, characterized by an increased uptake and retention of iron within the cells of the reticuloendothelial system (liver/spleen), resulting in decreased RBC production. Essentially, iron is present but inaccessible for use in the production of Hgb with the erythrocytes (Bross et al., 2010). A shortened RBC survival is also a contributing factor to ACD.

Question 8.
The main focus of treatment of patients with ACD is:
Replenishing iron stores
Providing for adequate nutrition high in iron CORRECT Management of the underlying disorder
Administration of monthly vitamin B12 injections
Instructor Explanation: Treatment: Treatment of ACD focuses on management of the underlying disorder. Iron supplementation is of no benefit in ACD, except in cases of coexisting IDA. A therapeutic trial of iron supplementation of no longer than 1 month may be useful in delineating between ACD and IDA. In ACD, there would be no hematological response to iron therapy (Chen & Gandhi, 2004). (Kennedy-Malone page 518)

Question 9.
In addition to the complete blood count (CBC) with differential, which of the following laboratory tests is considered to be most useful in diagnosing ACD and IDA?
