C. Longitudinal studies
D. Case control studies
3.
All of the following statements are true about laboratory values in older adults except:
A. Reference ranges are preferable
B. Abnormal findings are often due to physiological aging
C. Normal ranges may not be applicable for older adults
D. Reference values are not necessarily acceptable values
4.
Biochemical individuality is best described as:
A. Each individual’s variation is often much greater than that of a larger group
B. The unique biochemical profile of a selected population
C. The truly “normal” individual—falling within average range
D. Each individual’s variation is often much smaller than that of a larger group
5.
Polypharmacy is best described as taking:
A. More than nine medications per day
B. More than five medications per day
C. Even a single medication if there is not a clear indication for its use
D. When a drug is given to treat the side effect of another drug
6.
Pharmacokinetic changes with aging is reflective of:

B. What the body does to the drug
C. The effect at the site of action and the time and intensity of the drug
D. The side effects commonly associated with the drug
7.
All the following statements are false about drug absorption except:
A. Antacids increase the bioavailability of digitalis
B. Gastric acidity decreases with age

8.
All of the following statements are true about drug distribution in the elderly except:
A. Drugs distributed in water have lower concentration
B. Drugs distributed in fat have less intense, more prolonged effect
C. Drugs highly protein bound have greater potential to cause an adverse drug reaction
D. The fastest way to deliver a drug to the action site is by inhalation
9.
