Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.

The difference between different types of levers are:

1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.

 

2. The class II levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.  

3. The class III levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.  

Thus, the correct answer is Option 1.

Which type of doctor specializes in teeth and jaw alignment?
Snowcat [4.5K]
Dentists are doctors that specialize in teeth and jaw alignment. They are also doctors but their only focus is in the oral cavity. They could also perform surgeries and anesthesia in patients and are probably one of the most lucrative types of professions in society. If you want to have procedures done with your teeth you should consult with a dentist and ask for possible solutions as to how you can improve your oral cavity. Aside from the teeth they are also concerned with the proper alignment of the jaws.

JulijaS [17]
The neuron is the basic unit of the nervous system of the body. Its function is to send information to the brain (communication). Neurons help us to react to changes in our environment. Sensory neurons detect the pain the young  woman feels and send the messages from her burned skin to her brain. Interneurons integrate the information and generate instructions how to respond.

Web search: Dosage Errors Find a law case or news story on a medical error caused by a pharmaceutical dosing mistake. May not us
adell [148]

A hospital in Bend, Oregon, says it administered the wrong medication to a patient, causing her death.

Loretta Macpherson, 65, died shortly after she was given a paralyzing agent typically used during surgeries instead of an anti-seizure medication, said Dr. Michel Boileau, chief clinical officer for St. Charles Health System.

He said Macpherson stopped breathing and suffered cardiac arrest and brain damage.

Macpherson came into the ER two days earlier with medication dosage questions after a recent brain surgery.

Three employees involved in the error have been placed on paid leave. The organization is conducting an investigation, but doesn't yet know how the error occurred, Boileau said.

The investigation is looking at every step of the medication process: from how the medication was ordered from the manufacturer, to how the pharmacy mixed, packaged and labeled the drug, to how it was brought to the nurses and administered to the patient.

"We're looking for any gaps or weaknesses in the process, or to see if there has been any human error involved," Boileau said.

The hospital notified the Deschutes County district attorney, who did not immediately return a call for comment.

According to the Bend Bulletin, the doctors determined Macpherson needed an intravenous anti-seizure medication called fosphenytoin, but instead accidentally administered rocuronium, which caused Macpherson to stop breathing and go into cardiac arrest, leading to irreversible brain damage. The hospital took Macpherson off life support Wednesday morning.

The patient's son, Mark Macpherson told the newspaper he'd recently moved to closer to care for her. "We didn't get the answer for a couple of days about what had happened, but when they first told us, it was pure anger," he told the paper, adding that he wasn't sure if the family planned to pursue legal action.

Boileau told the newspaper this was the first time the hospital has dealt with a situation like this. "We are in the process of that analysis right now. Before we say exactly what happened, we're going to make sure we're accurate about. We do know there was a medication error. We acknowledge that. It's our mistake."

Studies show hundreds of thousands of people die every year in the U.S. due to hospital errors, although it's not clear how many of those cases involve drug mix-ups like this one. A report published in the Journal of Patient Safety last year says the number of deaths due to preventable hospital errors ranges from 210,000 to 400,000 people each year. Earlier this week, the Department of Health and Human Services reported that such errors declined by 17 percent between 2010 and 2013.

Research and read about the stress study conducted in Baltimore called “Shifting the Lens,” which focused on stressors in Africa
NeX [460]

Answer:

(Answers may vary)

Yes, I do agree with the findings of the Baltimore study “Shifting the Lens.” The study found that parents, family, and interpersonal relationships with school friends are the leading stressors in a teenager’s life. Most people believe that the leading causes of stress are problems with authority, peer pressure, drugs, alcohol, and so on. While this is true to some extent for many teenagers, most teenagers have a harder time coping with everyday stressors.

Some of my main stressors include family problems (disagreements with my parents about my allowance, chores, and curfew); my performance at school (I’m good at languages, but I struggle with math); my worries about the future (about what colleges will accept me); and my hectic schedule, crammed full of school and sports activities. My schedule can be hard to juggle and leaves me with very little personal time.

To cope with my stress, I have my family and my closest friends for support. When I’m upset with my parents, I talk to them about it. My friends have similar stresses, so they empathize. In addition to sharing how I feel, I’ve also found that hobbies help to take my mind off the stressors. Therefore, no matter how busy I am, I try to paint and read when I’m feeling stressed. Keeping a diary also helps me to process my thoughts and feelings. Sometimes, instead of immediately reacting to a stressor, I write down how I’m feeling. It helps me to vent as well as to calm down and rationalize my feelings.
