A total of 850 insulation workers employed between 1940 and 1945 was identified from the personnel records of three large insulation manufacturing plants in the Midwestern U.S. in 1980. During the period 1940-1980, 28 deaths from lung cancer were discovered among the workers. Only eight lung cancer deaths, however, were reported among a comparable group of 800 coworkers who did not work with insulation during the same time period. The investigators had hypothesized that exposure to the insulation material increases the risk of lung cancer.

The mechanism by which energy is produced for our ability to do work is known as energy systems

1. The correct option that fills the gaps for the type of predominant energy system being used are;

Phosphagen systemGlycolytic systemOxidative systemOxidative system

2. The macronutrients utilized are;

Carbohydrates, fats and proteinsPhosphocreatineGlycogen

The reason the above energy systems and macronutrients are correct are as follows:

The three energy systems used boxing are;

The phosphagen system; 10 to 30 seconds of intense activities, and replenishes in 3 to 5 minutes

The glycolytic system; Intense activity that lasts from 30 seconds to 3 minutes

The oxidative system; Low intensity activities that last for long duration

The first punch within 3 seconds of starting makes use of the

phosphagen system. The body makes use of the store of ATP to create an

explosive effect of throwing first punch

During the continuous flurry of jabs and fast moves that lasts up to 30

seconds after 1.5 minutes into the round, the body makes use of glycolytic

system

The oxidative system is used for the moderate activity of moving

around in the ring that last 30 seconds out of the 3 minutes round

The oxidative system is used when resting such as sitting on the stool

in the corner of the ring during the 1-minute rest between rounds

2. The micronutrients being utilized are;

Carbohydrates, fats and proteins are the micronutrients used when sitting on the stool in the corner of the ring during the 1-minute rest between rounds when the oxidative system is being usedPhosphocreatine and the store of ATP is used within 3 seconds of starting the round when the phosphagen system is being usedGlycogen is used as the macronutrient during the 30 seconds of 3 minute round while moderately moving around the ring

The intercondylar fossa of femur (intercondyloid fossa of femur, intercondylar notch of femur) is a deep notch between the rear surfaces of the medial and lateral epicondyle of the femur, two protrusions on the distal end of the femur (thigh bone) that joins the knee. On the front of the femur, the condyles are but much less prominent and are separated from one another by a smooth shallow articular depression called the patellar surface because it articulates with the posterior surface of the patella (kneecap).

The intercondylar fossa of femur and/or the patellar surface may also be referred to as the patellar groove, patellar sulcus, patellofemoral groove, femoropatellar groove, femoral groove, femoral sulcus, trochlear groove of femur, trochlear sulcus of femur, trochlear surface of femur, or trochlea of femur.

Farrah hasn't been feeling well for several days . She knows her boss isn't super understanding when it comes to calling in sick , and it's a really busy time at work , but she's in rough shape . What should she do? a) Go to work but wear a mask to cover her mouth b) Stay home for at least a day to keep from spreading germs c) Go in but try to avoid coming into contact with others d) Plan to go in but come home after lunch if she doesn't feel better

Answers

Obviously from reason as of right now, Farrah should consider staying home just to make sure she doesn’t spread germs.

Option A, wearing a mask would help if she was conditional (semi-healthy) but because you mentioned that Farrah is in a rough shape, the mask really won’t do too good as it cannot completely filter the air.

Option C, avoiding contact is a finer solution but for how long can you stay away from interactions? You would have to interact with the materials such as desks, chairs, pens, etc. Others are most likely to use those same material which would cause unwanted spreading through indirect contact.

Option D, coming back home after lunch is also a reasonable answer but their is no mask/avoidance of contact induced, your just working normally as you would on a regular day. This can cause several health issues to rise as you aren’t taking the precautions you should. And even if you are, there is no guarantee you would be able to do your job as you are in a position where your health is at risk.

Even if your options are limited, or your situation isn’t ideal, you should never put your own health and other’s health at risk.

Staying at home is doing the favour for both you and those around you.

A vial of streptomycin sulfate is to be reconstituted for IM injection in

instructions say to add 9 mL of sterile water; this results in a
concentration of 400 mg/mL. What is the volume of the dose in mL
needed to fill a doctor's order for 500 mg daily?
1.25 mg
1.25 L
1.25 mL
1.25 mg/ml

Answers

Answer:

Explanation:

9 mL contains 400 mg/ mL

If you want a dose of 500 mg you would need to take 1.25 mL of the dilute solution.

This problem couldn't be more deceptively worded. The only fact you can rely on is the concentration becoming 400 mg / mL

You come to the answer by figuring out how to get 500 mg.

400 mg / mL * x = 500 mg      Divide by 400 mg / mL. Watch the units.

x = 500 mg// 400 mg / mL      The mg cancel out.

x = 1.25 mL

A patient is given an initial dose of 200 mg of quinidine sulfate, followed later in the day by two 200-mg doses. The daily dosage is then increased by 200 mg/day until a daily dose of 3000 mg is reached. How many 200-mg quinidine sulfate tablets will be needed for this regimen?

Answers

The number of 200-mg quinidine sulfate tablets that will be needed for this regimen is 15 tablets.

Since the patient is given an initial dose of 200 mg of quinidine sulfate, followed later in the day by two 200-mg doses. And since the daily dosage is then increased by 200 mg/day until a daily dose of 3000 mg is reached.

His daily dosage is thus 3000 mg per day.

Since we have 200-mg quinidine sulfate tablets, we require the number of 200-mg quinidine sulfate tablets that would give a dose of 3000 mg.

so, number of tablets required, n = dose/dose per tablet.

The dose = 3000 mg and the dose per tablet = 200 mg

n = dose/dose per tablet.

n = 3000 mg/200 mg

n = 15 tablets

So, the number of 200-mg quinidine sulfate tablets that will be needed for this regimen is 15 tablets.

John fell to the ground and experienced significant pain when putting weight on his right leg. John tried to walk but had to be carried off the field and was taken to the emergency department.
