An epidemiologic survey of roller-skating accidents in Juneau, Alaska, a city with a population of 100,000, produced the following:

Number of skaters in Juneau during any given month: 12,000
Roller-skating accidents in Juneau: 600
Total number of residents injured from roller-skating: 1,800
Total number of deaths from roller-skating: 90
Total number of deaths from all causes: 900

Required:
Calculate:
a. Crude death rate.
b. The cause-specific mortality rate from roller-skating.
c. The proportionate mortality (%).
d. The case fatality rate of roller-skating accidents.

Answers

Answer 1

Answer:

A. 900

B. 90

C. 10%

D. 15%

Explanation:

A. Calculation for Crude death rate.

Crude death rate =900/100,000 × 100,000

Crude death rate =900

Therefore the Crude death rate was 900

B. Calculation for The cause-specific mortality rate from roller-skating

Cause-specific mortality rate from roller-skating=90/100,000 × 100,000

Cause-specific mortality rate from roller-skating=90

Therefore the Cause-specific mortality rate from roller-skating was 90

C. Calculation for The proportionate mortality (%).

Proportionate mortality (%)=90/900 × 100

Proportionate mortality (%)=10%

Therefore The proportionate mortality (%) was 10%

D. Calculation for The case fatality rate of roller-skating accidents.

Case fatality rate of roller-skating accidents=90/600*100

Case fatality rate of roller-skating accidents=15%

Therefore the Case fatality rate of roller-skating accidents was 15%

It is true that Use of narcotic drugs over a long period time leads to the development of tolerance for the narcotic.

What is narcotic tolerance?Drug tolerance, also known as drug insensitivity, is a pharmacological term for a person's reduced response to a drug following repeated use. Increasing the dosage may re-amplify the drug's effects, but it also has the potential to accelerate tolerance, further reducing the drug's benefits.Heavy drinkers, for example, develop tolerance to alcohol (requiring them to consume larger amounts to achieve the same effect), yet excessive drinking can harm the liver, placing them at risk of intoxication even when only consuming small amounts.

Research shows that Piaget’s theory of cognitive development has important educational implications. Select one stage of cognitive development (according to the theory) and discuss at least three activities that would be beneficial in teaching children who are in that developmental stage.

Answers

Answer:

(Answer may vary.)

Piaget’s theory of cognitive development features four main stages, which occur at different ages: sensorimotor stage, preoperational stage, concrete operational stage, and formal operational stage. These developmental stages can have significant implications on a child’s ability to learn. Some activities and strategies that can be beneficial for teaching children who are in the third stage of Piaget’s theory of cognitive development (the concrete operational stage, between seven and eleven years of age) include the following:

Children’s cognitive skills and problem-solving abilities reach a higher level at this stage. A good of way of refining these skills is to have children solve simple puzzles (such as jigsaw puzzles) that make them think of various alternatives with respect to the shapes and sizes of the pieces. Children at this age have developed a high level of object permanence, and they are able to learn while they have fun solving such puzzles.

In order to enhance children’s problem-solving skills during this stage, teachers should give them mathematical (numerical) problems to solve. For instance, simple problems involving addition, subtraction, multiplication, division, etc., can help children use and develop their cognitive skills in an optimal manner.

At this stage, teachers can enhance children’s reasoning skills through comparison activities. For example, they can ask children to compare two similar (but not identical) pictures and point out the differences between them. Similarly, children could compare two objects and list specific comparative properties, such as which is taller, broader, heavier, lighter, etc.

Explanation:

PLATO

The one stage of cognitive development according to Piaget is the Concrete operational stage which is implicated in the children of age groups 7-11 years.

What is Cognitive development?

Cognitive development may be defined as a field of study that involves the growth of a child's ability to think and reason and behave in response to the external or internal stimuli.

The three activities that would be beneficial in teaching children who are in that developmental stage are logical operations, logical reasoning, and classification.

Therefore, it is well described above.

What are the four questions a consumer should consider in determining is nutrition information found on the Internet is reliable?

Answers

Answer:

The four questions a consumer should consider in determining is nutrition information found on the Internet is reliable are:

1- Is the source of information reliable? Well, if it is not, nothing that is said there can be taken as true without a prior evaluation, comparing the information with other available sources.

2- Does the information contain checkable data? For if it did not have them, and were based on empty statements, it could not be shown that what is stated is true.

3- Was it written by a nutrition professional? Well, even if it has data and it comes from a reliable source, if it was not written by a qualified professional in the field, such information should be considered as doubtful.

4- Is it supported by formal academic research? Well, if this is so, there will be no doubt that the information is correct and serious.

You are caring for ER, a 28 year old female. She and her husband were having breakfast when she suddenly stopped responding to him. Her husband states, "She just stared into space and kept saying, ‘It’s like this, it’s like this, it’s like this.’" When her husband put his hand on her arm, she hit him. He called 911 and they are now in the emergency department and she is being evaluated for seizure disorder.

Required:
a. What kind of seizure might ER have had? Explain your answer.
b. What assessments and diagnostics will be used to rule seizure disorder in or out?
c. ER’s husband says, "It can’t be seizures. She didn’t fall on the ground and bite her tongue." How will you explain seizure disorder to ER and her husband?
d. If ER is diagnosed with seizures, what will you teach ER and her husband about managing her seizure disorder?

Answers

Explanation:

1. what ER is experiencing can be regarded as simple partial seizure. This is why, in this type of seizure she still maintained awareness. This kind of seizure can cause someone to act the way she did by staring into space and continuously repeating the same thing.

2. The assessments and diagnostics are:

neurological assessmentEEG test to see if there are changes in her brain activity, this test helps to diagnose brain conditions especially in people that suffer from seizures.other assessments and diagnostics are CT scan and MRI scan.

3. Her husband clearly thinks that all kinds o seizures are the same. because she did not fall fall or bite her tongue he doesn't think she had a seizure. He has to be educated to know that seizures are of different types and each of these types have different symptoms. He should know that people can lose consciousness in one type and not lose consciousness in  the other, they may even be able to talk, and remember things during the attack.

4. If she is diagnosed to have seizures, I am going to teach her  and her husband to manage the condition by;

encouraging her on how necessary it is for her to always take her medications as the doctor prescribed.i would tell her to make sure that she avoids whatever can trigger stress, anxiety and emotional disorder.They should do away with sharp objects in  the house during such episodes.Whenever symptoms present themselves, they should report immediately.
