After an open reduction and internal fixation of a fractured hip, the nurse is helping a client to get out of bed into a chair.
PIT_PIT [208]
<span>I think the answer would be: instruct the client to bear most of the weight on the unaffected leg and pivot to the chair.
</span>
Hip is a complex and thin bone. Repairing it will be harder than big bones and it will be easier to break again. The client should try to not burden the fractured bone to reduce the risk. At least you need to give the bone time to heal themselves.

When vesicles of the cardiac sarcoplasmic reticulum (CSR) are incubated with ATP Mg^2+ and Ca^2+, they take up Ca^2+ and reach a
abruzzese [7]

Answer

I added 4 and 5 as an attachment due to time constraint.

Explanation:

1. at a steady state ca2+ taken by vesicle = 40n/mol

enclosed volume of CSR = 5μ/mg

concentration of ca2+ in vesicle =

40*10⁻⁶/5x10⁻⁶

= 0.008

= 8x10⁻⁹mol/L

2. radius of circle =75nM

volume = 150nm

volume of vesicle = 4/3 x pi x r³

= 1.33 x 3.14 x (75x10⁻⁹)³

= 1.77 x 10⁻²¹

when we convert this we get

1.77x10⁻¹⁸L since 1m³ is equal to 100oL

surface area =4x3.14x(75x10⁻⁹)²

= 12.56x5.625⁻¹⁵

= 7.065x10⁻¹⁴m²

this is 7.065x10⁻¹⁰cm²

3. number of vesicle/CSR

= 5x10⁻⁶/1.77x10⁻¹⁸

= 2.824x10¹²

surface are = 2.824x10¹² x7.06x10⁻¹⁰

= 19.95x10²

The enzyme DNA polymerase works only in the 5′ to 3′ direction. How does this affect the leading strand and the lagging strand?
aliina [53]

Answer:

B

Explanation:

DNA replication is semiconservative- meaning the old template strand will form a double helix with the newly synthesized strand. The DNA polymerase can only replicate DNA in the 5’ -> 3’ direction on a DNA strand. However, because the two strands of a DNA double helix run antiparallel (and they are replicated together), then during replication, one strand will be oriented in the opposite direction (i.e 3’ -> 5’ direction).

Because DNA polymerase requires a primer to begin replication, the leading strand will require one primer, because replication on this strand occurs continuously. On the lagging strand, many primers are required because replication is done piecemeal forming fragments called Okazaki fragments. The fragments are later joined by DNA ligases.

what do you need to do to be sure turnip peroxidase is responsible for the color change of guaiacol and not some other turnip en
nika2105 [10]

Answer:

Purify peroxidase through metal affinity chromatography

Explanation:

In order to make sure the turnip peroxidase is responsible for the color change of guaiacol and not some other turnip enzyme it would be necessary to purify peroxidase through metal affinity chromatography. For the change of color some factors need to be appreciated too, pH, enzyme concentration and temperature will influence the reaction. Peroxidase is a heme, an enzyme encouraged of the catalyze reaction of hydrogen peroxide.
