In which of the following situations would blood most likely rapidly relocate from central circulation to the lower extremities?
 
  A)
  A client undergoes a stress test on a treadmill.
  B)
  A client does isotonic exercises in a wheelchair.
  C)
  A client is helped out of bed and stands up.
  D)
  A client reclines from a sitting to supine position.

Question 2

A 74-year-old man is being assessed by a nurse as part of a weekly, basic health assessment at the long-term care facility where he resides.
 
  His blood pressure at the time is 148/97 mm Hg, with a consequent pulse pressure of 51 mm Hg. The nurse would recognize that which of the following is the most significant determinant of the resident's pulse pressure?
  A)
  Blood volume, resistance, and flow
  B)
  The cardiac reserve or possible increase in cardiac output over normal resting level
  C)
  The amount of blood that his heart ejects from the left ventricle during each beat
  D)
  The relationship between total blood volume and resting heart rate

Answer to Question 1

Ans:
C

Feedback:

During a change in body position, blood is rapidly relocated from the central circulation (when the patient is recumbent) to the lower extremities (when the patient stands up). This results in a temporary drop in blood pressure known as postural hypotension and reflects the redistribution of blood in the body.

Answer to Question 2

Ans:
C

Feedback:

Pulse pressure is a reflection of the amount of blood that the heart ejects from the left ventricle during each beat combined with the distensibility of the atrial tree. Other factors such as blood flow characteristics, cardiac reserve, heart rate, and blood volume are less directly associated with pulse pressure.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).
