A client in skeletal traction has a nursing diagnosis of Impaired Tissue Integrity: Related to puncture wound; pins.

VladimirAG [237]

Answer:

The client traction weights are resting on the floor.

Explanation:

The immediate action of the nurse should be to reapply the weights to give traction to the fracture. The health care provider must be notified that the weights were lying on the floor, and the client should be realigned in bed. The client's blood pressure is slightly elevated; this could be related to pain and muscle spasms resulting from lack of pressure to reduce the fracture. Oozing of clear fluid is normal, as is the capillary refill time.

1. Suppose the synthesis of an amino acid was accomplished by four enzymes encoded by four genes that formed an operon. Draw a m

vivado [14]

I have attached lac operon model having 4 genes. See attachment for better understanding.

Answer:

The Lac operon is controlled by two signals.

Initiation

Glucose and lactose concentrations control the initiation of transcription of the Lac operon through their effects on the Lac repressor protein and Cap.

Lactose absent (Repression)

When lactose is absent, the Lac repressor binds the Lac operator and shuts off expression of the operon.

Lactose present (Transcription)

Addition of lactose increases the intracellular concentration of a related compound, allolactose. allolactose binds to the Lac repressor, causing it to undergo a conformational change that releases its grip on the operator DNa.

Glucose absent (Repression)

When glucose is absent, cyclic aMp (red triangle) is produced by the cell and Cap binds to DNA.

Glucose present (Transcription)

LacZ, the first gene of the operon, encodes the enzyme b-galactosidase, which breaks down lactose to galactose and glucose.

Compare a natural meadow with a cornfield in terms of biodiversity. in your answer, be sure to address the: • number of species

Mademuasel [1]

In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.

In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.
