Aclient has an above-the-knee amputation of the left leg because of arterial insufficiency. to prevent a hip flexion contracture, in what position should the nurse periodically place this client?

The nurse should put the client at prone position a couple of times in a day for about 20 minutes to prevent hip flexion contracture. The client can be position in supine but the stump must be elevated for the first 24 hours by uplifting the foot of the bed instead of using pillow. The elevation of residual limb after surgery helps lessen edema and pain by increasing venous return and decreasing venous pooling at the distal portion of the extremity.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
