Question

1. Which of the following pulmonary measurements will be most affected in an individual with COPD?

a.) SVC

b.) Percentage of the FVC that can be exhaled in 1 sec (FEV1/FVC)

c.) Total lung capacity

d.) Tidal Volume

2. The Biodex Balance System may be used to assess

a.) Two of the choices listed

b.) All the the choices listed

c.) balance deficits associated with a head injury.

d.) risk of falling.

e.) unilateral postural stability on an unstable surface.

3. If your client fails to fully exhale while being weighed underwater, what effect will this have on the calculated body fat percentage?

a.) Body fat percentage will be underestimated.

b.) Body fat percentage will be overestimated.

c.) No effect on body fat percentage

d.) Body fat percentage will be overestimated in women and underestimated in men.

4. Which of the following balance assessments include activities of daily living?

a.) Berg Balance Scale

b.) Limits of stability assessment on the Biodex Balance System

c.) Balance Error Scoring System

d.) Y-balance test

Answer 1

1.b.) Percentage of the FVC that can be exhaled in 1 sec (FEV1/FVC)

The ratio of FVC and FEV1 can help doctors diagnose the COPD. If FEV1 value is less than 80 percent of an FVC, it indicates COPD.Tidal volume,svc and total lung capacity will tell you the variations but cant be used to diagnose COPD precisely.

2.b.) All the the choices listed

The Biodex Balance System is used to assess balance deficits associated with a head injury,risk of falling and unilateral postural stability on an unstable surface.Therefore the option b is best answer.

3.a) Body fat percentage will be underestimated.

If the person fails to exhale fully it increases the Residual volume in calculation and thereby increasing the denominator in the formula and thus cause a reduction in the BF value .As the foumula is same for both gender,the best answer is option A.

4.b)Limits of stability assessment on the Biodex Balance System

Limits of stability assessment on the biodex balance system assess the stability issues with ADL activities in comparison with the other given option.
