A 40-year-old patient had an annual physical exam with routine lab tests. The patient's lab values include the following:
 
  Hgb
 
  13.8 g/dL
 
  Hct
 
  40
 
  BG fasting
 
  146 mg/dL
 
  Triglycerides
 
  200 mg/dL
 
  Total cholesterol
 
  231 mg/dL
 
  LDL
 
  175 mg/dL
 
  HDL
 
  30 mg/dL
 
  The client was counseled to begin an exercise and diet regime for his health. After implementing healthy lifestyle changes 6 months ago, follow-up lab tests were drawn. Which of the following lab values indicate that the changes have been effective?
  A)
  Triglycerides elevated to 210 mg/dL
  B)
  LDL level decreased to 120 mg/dL
  C)
  Hgb decreased to 12.3 g/dL
  D)
  HDL increased to 35 mg/dL

Question 2

The medical team is assessing a newly admitted patient who is hypothermic following a night spent lost on a ski slope.
 
  The health care professionals would recognize that which of the following phenomena most likely contributed to minimizing the client's heat loss in a cold environment?
  A)
  The high heat conductivity of subcutaneous tissue protected against core heat loss.
  B)
  Increased blood flow to the outer shell prevented superficial freezing and loss of heat.
  C)
  The tissue thickness of the outer shell increased and preserved heat.
  D)
  Shell temperature dropped, minimizing the temperature variance between the core temperature and environmental temperature.

Answer to Question 1

Ans:
B

Feedback:

Physical activity and exercise can help maintain weight control and CV fitness. Physical activity and exercise can lower LDL and increase HDL in persons with hyperlipidemia and have better regulation of blood glucose.

Answer to Question 2

Ans:
C

Feedback:

The thickness of the outer shell is modifiable in response to the environmental temperature and can be increased through decreased blood flow. Subcutaneous tissue provides protection due to its low, not high, conductivity. Blood flow decreases to the outer shell in low temperatures, and the lowering of the shell temperature does not necessarily minimize heat loss.

Astigmatism is the most common vision problem. It may accompany nearsightedness or farsightedness. It is usually caused by an irregularly shaped cornea, but sometimes it is the result of an irregularly shaped lens. Either type can be corrected by eyeglasses, contact lenses, or refractive surgery.
