State the reason why some drugs are considered drugs of abuse.

You have bandaged a victim's lacerated elbow. Blood is still soaking through the dressing and bandage. What should you do?

morpeh [17]

Answer: The correct answer to the question is option D

APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

Explanation: To answer the question effectively,let's look at the options critically and the effects it will have on a bandaged lacerated elbow that still has blood soaking through the dressing and bandage.

A) Remove the dressing and bandage and start over again with a tighter bandage.

This is a big NO when it comes to wound dressing and care because removing the dressing and bandage will impair the blood clots that must have formed in the lacerated site,this blood clots helps to control the bleeding so when the bandage and dressing is removed,the blood clot will be distorted which will make the wound to start bleeding again.

B) Apply a tourniquet around the wrist.

Application of tourniquet is the last resort in control of bleeding,it is only employed when other measures to control the bleeding has been applied but proved abortive so application of tourniquet is not the right and appropriate measure to be taken at this time.

C) There is nothing else you can do.

This can be termed an act of negligence and its not expected of a healthcare provider,leaving the victims lacerated elbow to be soaking of blood through the dressing and bandage will cause the victim to loose much blood and this might result to shock.(hypovolemic shock)

D) APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

This is the right and most appropriate measure to be taken in the case of a laceration or wound that has blood still soaking through the wound and dressing. The goal is to apply more pressure inorder to maintain homeostasis (control the bleeding).

The arm should also be lifted above the heart to decrease the flow of blood,improve venous return and prevent obstruction of a blood vessel as a result of a blood clot. (thromboembolism).

After the measures has been ensured,the victim should be closely monitored for any skin discoloration (blueish discoloration especially of the extremities),signs indicative of shock,faster breathing or slower breathing and restlessness.

Which processes need to increase (for Glucose, more toward Glucagon) in order to achieve normality and which need to move down (

AfilCa [17]

Answer:

Gluconeogenesis is needed to increase the blood glucose level and glycolysis is need to decrease or to move down the blood glucose level

Explanation:

Gluconeogenesis and glycolysis occur inside our body in response the blood glucose level.

When blood glucose level is low at that time gluconeogenesis is triggered by hormone glucagon released from alpha cells of pancreas by the same way when the glucose level is high at that time glycolysis is triggered by the insulin hormone.

The two processes gluconeogenesis and glycolysis occur in oue body to maintain homeostasis of blood glucose level.

Adenine, thymine, cytosine and guanine are ___________________ instructions to cells.

const2013 [10]

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.

How does transcription proceed?

Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.
