A physiotherapist (PT) at an assisted living facility for older adults is leading an exercise class for the residents.
 
  Part of the PT's introductory class is an explanation of the health problems that can be mitigated by physical activity and those that are considered inevitabilities of the aging process. Which of the following phenomena would the PT most justifiably characterize as modifiable?
  A)
  Reduction in density of the trabecular bone
  B)
  Gradual decline in physical reaction time
  C)
  Overall reduction in muscle strength
  D)
  Decline in height

Question 2

A physician is providing care for a number of patients on a medical unit of a large, university hospital.
 
  The physician is discussing with a colleague the differentiation between diseases that are caused by abnormal molecules and diseases that cause disease. Which of the following patients most clearly demonstrates the consequences of molecules that cause disease?
  A)
  A 31-year-old woman with sickle cell anemia who is receiving a transfusion of packed red blood cells
  B)
  A 91-year-old woman who has experienced an ischemic stroke resulting from familial hypercholesterolemi a
  C)

Answer to Question 1

Ans:
C

Feedback:

While a general reduction in muscle strength is a normal, age-related change, this can be slowed significantly by regular physical activity. Loss of bone density in the trabecular bone, decreases in reaction time, and loss of height are less modifiable.

Answer to Question 2

Ans:
D

Feedback:

PCP is an example of the effect of a molecule that directly contributes to disease. Sickle cell anemia, familial hypercholesterolemi a, and cystic fibrosis are all examples of the effects of abnormal molecules.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
