Which of the following actions are effective in reducing friction when repositioning a patient in bed? (Select all that apply.)
 
  a. Lifting rather than pushing
  b. Pushing the patient up in bed
  c. Asking the patient to bend his or her knees and lift the hips when moving up in bed
  d. Asking the patient to lie still as you repo-sition him or her; even when the patient offers to help
  e. The use of a draw sheet
  f. The use of a transfer board

Question 2

Two nursing students were having pizza one evening as they were studying. One student remarked that whenever she ate pizza, she was incredibly thirsty. The second student explained that this thirst was caused by:
 
  a. colloid osmotic pressure.
  b. osmoreceptors.
  c. oncotic pressure.
  d. hydrostatic pressure.

Answer to Question 1

A, C, E, F
You reduce friction by lifting rather than pushing a patient. Lifting has an upward component and decreases the pressure between the patient and the bed or chair. The use of a draw sheet re-duces friction because you are able to move the patient more easily along the bed's surface. However, there are several commercially available products to assist in the task of positioning and moving patients in bed such as transfer boards and Maxi Slides. Pushing the patient up in bed is incorrect because pushing increases the friction between the patient and the bed. Asking the patient to lie still is incorrect because a passive or immobilized patient produces greater fric-tion to movement.

Answer to Question 2

B
Thirst, a conscious desire for water, regulates fluid intake when plasma osmolality increases (osmoreceptor-mediated thirst) or the blood volume decreases (baroreceptor-mediated thirst and angiotensin IImediated thirst). The thirst-control mechanism is in the hypothalamus of the brain. Osmoreceptors there continually monitor plasma osmolality; when osmolality increases, the hy-pothalamus stimulates thirst. Colloid osmotic pressure (oncotic pressure) is an inward-pulling force caused by the presence of protein molecules. Hydrostatic pressure is the force of a fluid pressing outward against the walls of its container. Thus capillary hydrostatic pressure is an out-ward-pushing force.
