Question : The major impact of the physiological changes that occur with aging is: Student Answer: Reduced physiological reserve Reduced homeostatic mechanisms Impaired immunological response ... All of the above Instructor Explanation: The major impact of all of these physiological changes can be highlighted with three primary points. First, there is a reduced physiological reserve of most body systems, particularly cardiac, respiratory, and renal. Second, there are reduced homeostatic mechanisms that fail to adjust regulatory systems such as temperature control and fluid and electrolyte balance. Third, there is impaired immunological function: infection risk is greater, and autoimmune diseases are more prevalent.

Points Received: 2 of 2 Comments: Question 2 . Question : Men have faster and more efficient biotransformation of drugs and this is thought to be due to: Student Answer: Less obesity rates than women Prostate enlargement Testosterone -582355588 MultipleChoice 1 True 0 -582355588 MultipleChoice 1 Less estrogen than women Instructor Explanation: Men have faster and more efficient biotransformation, presumably because of serum testosterone. Conditions of increased or decreased liver perfusion alter the overall level of the drug that is absorbed and how it is metabolized.

Points Received: 2 of 2 Comments: Question 3 . Question : The cytochrome p system involves enzymes that are generally: Student Answer: Inhibited by drugs Induced by drugs Inhibited or induced by drugs Associated with decreased liver perfusion Instructor Explanation: Biotransformation occurs in all body tissues but primarily in the liver, where enzymatic activity (cytochrome P [CYP] system) alters and detoxifies the drug and prepares it for excretion.

Question : Functional abilities are best assessed by: Student Answer: Self-report of function Observed assessment of function A comprehensive head-to-toe examination Family report of function Instructor Explanation: Two well-established tools used to evaluate function in older adults are the Katz Activities of Daily Living Scale (Katz et al., 1963) and the Lawton and Brody scale for Instrumental Activities of Daily Living (Lawton & Brody, 1969). It is important to be cautious about self-report of function (rather than direct observation of function) and to ask, “Do you …?” instead of “Can you …?” in order to determine if patients actually perform the activity.

Points Received: 2 of 2 Comments: Question 5 . Question : Iron Deficiency Anemia (IDA) is classified as a microcytic, hypochromic anemia. This classification refers to which of the following laboratory data? Student Answer: Hemoglobin and Hematocrit Mean Corpuscular Volume (MCV) and Mean Corpuscular Hemoglobin (MCH) 0 -582355586 MultipleChoice 3 -582355585 MultipleChoice 4 True 0 -582355585 MultipleChoice 4 Serum ferritin and serum iron Total iron binding capacity and transferrin saturation Instructor Explanation: RBC indices reveal an MCV (mean corpuscular volume/RBC size) that will be decreased to <80 fL in adults; MCH (mean corpuscular hemoglobin/RBC color) will show hypochromia or pale cells; RBC distribution width (RDW)/volume variation will be increased.

Points Received: 0 of 2 Comments: Question 6 . Question : When interpreting laboratory data, you would expect to see the following in a patient with Anemia of Chronic Disease (ACD): Student Answer: Hemoglobin <12 g/dl, MCV decreased, MCH decreased Hemoglobin >12 g/dl, MCV increased, MCH increased Hemoglobin <12 g/dl, MCV normal, MCH normal Hemoglobin >12 g/dl, MCV decreased, MCH increased Instructor Explanation: Hemoglobin (Hgb): <12 g/dL (120 g/L) women <13 g/dL (130 g/L) men Rarely <10 g/dL (100 g/L) Mean corpuscular volume: 80–96 mcm3 (normocytic) Mean corpuscular hemoglobin Normochromic (normal color) RBC distribution width: normal (Kennedy-Malone page 517) Kennedy-Malone, Laurie, Kathleen Fletcher, Lori Martin-Plank.

Question : The pathophysiological hallmark of ACD is: Student Answer: Depleted iron stores 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.
