Answer:

Answer: The answer to the question is

19.6 ml

Explanation:

Patient of weight = 180 pounds

converting to Kg;

= 180/2.2= 81.81 kg approximately

The ordered dose= 12 mg /kg

In mg, it will be;

= 12mg× 81.81 kg= 981.72mg

The available dose= 50mg

and

The available volume= 1 ml

The required dose = ( the ordered dose/ the available dose) × the available volume

Imputing the values given,we have;

=( 981.72mg/50mg)× 1ml

which is;

Montelukast is a medication that works by blocking leukotrienes, which are chemicals produced by the body's immune system that cause inflammation and narrowing of airways in conditions such as asthma and allergies.

By blocking leukotrienes, montelukast can help reduce symptoms such as wheezing, coughing, and difficulty breathing.

It is typically used as a long-term control medication to help prevent asthma attacks and manage allergic rhinitis.

Montelukast is available in tablet form and is usually taken orally once a day.

As with all medications, it is important to follow the physician's instructions and report any side effects or concerns.

Which of the following is a good example of visual encoding?

Answers

A good example of visual encoding is thinking about a dog you want to adopt and having the image of the dog appear in your mind. The correct option is D.

What is visual encoding?

Visual encoding is remembering what you have seen. This is like you see a bird on the street, and you passed by it. Then you remember it in the home, the color of the bird, the type of bird, etc.

The first option, the lyric of a song, that you have not seen, will not come under visual coding. The second option is dreaming, which is different from visual coding.

The third one is remembering other things by seeing a thing similar to it, which is not visual encoding. Only the last option is correct because it shows seeing a dog and then remembering it afterward.

Thus, the correct option is  D. Thinking about a dog you want to adopt and having the image of the dog appear in your mind.

How does sleep deprivation affect your ability to drive? A recent study measured the effects on 19 professional drivers. Each driver participated in two experimental sessions: one after normal sleep and one after 27 hours of total sleep deprivation. The treatments were assigned in random order. In each session, performance was measured on a variety of tasks including a driving simulation.

Answers

Answer:

Sleep deprivation in general, is a very serious situation because it will affect the entire human system, and it can lead to severe health conditions, and even death.

In performing activities that require high levels of focus and coordination, like driving, a person requires all of his senses to be on keen alert, and all his reflexes and movements must be under control and coordinated.

However, sleep deprivation is considered today as serious as consuming alcohol when driving, because this situation deprives the brain, and the body at large, from that much needed coordination and control that it would have if it were rested. As such, when a person is sleep deprived, depending on the severity of the deprivation, they can loose coordination, loose control of their reflexes, lose focus, have memory and judgement impairment and even go so far as to suffer from narcolepsy, a condition in which the person literally loses all control of his body due to sleep deprivation. Basically, they fall asleep in the car. This can cause accidents that lead to death.

Answer:

Due to sleep deprivation drivers are seen to be drowsy while driving.

Explanation:

According to the experiment on the drivers, it has been seen that drowsy driving is the reason behind several tragic accidents in U.S.A. Drowsy driving has the reason of sleep deprivation behind it.

If a driver drives without having sufficient sleep, it is quite obvious for him to fall asleep while driving.  This hampers the concentration of the driver while driving and make him unable to drive properly. So, getting enough sleep is important for driving.

Describe the process of emulsification. Name the substance which performs this job. Name the organ that synthesizes this substance. Name the organ which stores and concentrates this substance. How does this substance get into the duodenum of the small intestine? g

Answers

Answer:

Emulsification is a process where two liquids that do not mix are mixed, in digestion, it is the breaking down of fat globules in the duodenum into tiny droplets

Explanation:

The substance which performs emulsification is called bile

Bile is synthesized in the liver

Bile is stored and concentrated in the gallbladder

Once bile has been synthesized, it moves out of the liver through the hepatic ducts, the ducts (left and right) join to form the common hepatic duct which joins the duct from the gallbladder called the cystic duct. This bile duct enters the small intestine through a sphinter (Oddi) below the stomach.
