Sit in the dark for a few minutes to let your eyes adjust. In near darkness, stare

directly at an object and attempt to make out the details. Now look at it using your peripheral

vision (from the side). Can you make it out more clearly? How does this relate to rods and cones?

Answers

Answer 1

Answer and Explanation:

By observing an object in an almost dark place and then observing the same object in a bright environment through peripheral vision, it is possible to understand more clearly the functions of rods and cones.

Cones and rods are two types of cells present in the retina and very important for vision. The rods allow us to be able to see in low light environments. Therefore, when we look at an object in an almost dark place, we are able to define the shape and what the object is, even if we cannot see the details of the object. This happens thanks to the rods, however, as the environment does not have much light, we do not see the colors of the object with much definition.

On the other hand, the cones are responsible for the visualization of colors and it is because of the cones that we are able to observe the colors of objects that are outside our focus of vision, that is, that are being observed by our peripheral vision, as long as there is light in the environment to reflect the colors.

Answer 2

By looking at the object in the near darkness and attempt to make out the details, one can understand rods and cones.

The peripheral vision refers to the side vision of the eye. It is vital for people to see the objects that are around them without the person needing to turn his or her head.

The cones and rods are the cells that are present in the retina and are vital for vision. It should be noted that while the rods allow us to be able to see in low light environments. The cones are responsible for the visualization of colors.

SBAR report is as follows:

Explanation:

S – Hi doctor, I am Ben, RN on AMU this side. I am currently caring for your patient Mr. O. I am concerned  because his vitals have changed and he has sudden abdominal pain with distention.  

B – Patient was admitted for syncope. Has a history of CHF and acute MI. Only medications patient  reports to take is the occasional NSAID for chronic back pain.  

A – The PCA reported to me that Mr. O is having black, tarry stools. He is having abdominal pain that he  rates as a 6 out of 10 and there is distention present. BP 94/66, pulse 114, and RR of 24, O2 is 97%. He   says he cannot get comfortable and is feeling unwell.  

R – I recommend that you come see the patient immediately, and that we remove any orders for NSAID   use and instead switch to a non NSAID such as acetaminophen.

Answer:

Answer:

6 The four of the early signals of a heart attack is:

1. Fatigue

2. Cold sweat

3. Shortness of breath

4. Lightheadedness or sudden dizziness

7 The two surgical procedures performed to treat heart disease are:

1. Thrombolytic therapy

Thrombolytic therapy is a treatment in which you are given medicines through a drip to dissolve a blood clot that is narrowing or blocking a coronary artery.

This improves blood flow to your heart muscle and around your body.

2. Defibrillation

rhythm when your heart stops beating properly during cardiac arrest. It may also be used to treat other heart rhythm problems (like if your heart beats too slowly or too fast).

Paddles or pads are put on your chest. A regulated electrical current is applied to your heart to make it start beating regularly again.

You may be given an implantable cardiac defibrillator (ICD). This small device is put into your chest and connected to your heart by one or more wire leads. It monitors your heart rhythm and corrects it if it beats too slowly, too fast or stops beating.

8 The two major types of strokes are:

1. Thrombotic stroke

2. Embolic stroke

Thrombotic stroke are strokes caused by a thrombus (blood clot) that develops in the arteries supplying blood to the brain. This type of stroke is usually seen in older persons, especially those with high cholesterol and atherosclerosis (a buildup of fat and lipids inside the walls of blood vessels) or diabetes.

Sometimes, symptoms of a thrombotic stroke can occur suddenly and often during sleep or in the early morning. At other times, it may occur gradually over a period of hours or even days.

Thrombotic strokes may be preceded by one or more "mini-strokes," called transient ischemic attacks, or TIAs. TIAs may last for a few minutes or up to 24 hours, and are often a warning sign that a stroke may occur. Although usually mild and transient, the symptoms caused by a TIA are similar to those caused by a stroke.

Another type of stroke that occurs in the small blood vessels in the brain is called a lacunar infarct. The word lacunar comes from the Latin word meaning "hole" or "cavity." Lacunar infarctions are often found in people who have diabetes or high blood pressure.

2. Embolic strokes are usually caused by a blood clot that forms elsewhere in the body (embolus) and travels through the bloodstream to the brain. Embolic strokes often result from heart disease or heart surgery and occur rapidly and without any warning signs. About 15% of embolic strokes occur in people with atrial fibrillation, a type of abnormal heart rhythm in which the upper chambers of the heart do not beat effectively.

9 four of the warning signs of a stroke are:

1. Dizziness

2. Difficulty speaking

3. Trouble seeing with one or both eyes

4. Severe headache that comes on for no reason

10 the three things you can do now to lower your risk of developing cardiovascular disease are:

1. Eat a healthy diet

2. Get regular exercise

3. Stay at a healthy weight

How important do you think it is to believe in your own argument when giving a persuasive speech? Explain your answer.

Answers

Answer:

Here's a sample response:

Persuasion is the process that is aimed at changing a person’s or a group’s attitude or behavior. A persuasive speech such as sales pitches, debates, and legal proceedings, typically use ethos, pathos and/or logos. When delivering this type of speech, your aim is to change or help develop your audience's point of view on a subject. The only real way to authentically gain a response, is if you truly believe what you are speaking about. There is no point in delivering a persuasive speech unless one has an argument to make. Usually we deliver a persuasive speech because we believe in the subject and that the subject has importance. All in all, to effectively give a persuasive speech, yes, you do need some level of belief in your argument.

Persuasion changes an individual or group's behaviour or attitude. Sales pitches, arguments, and legal processes employ ethos, pathos, and logos. This style of speech aims to modify your audience's perspective.

What is a persuasive speech?

A persuasive speech tends to educate, motivate, and persuade the audience to accept the author's specific point of view. This style of speech reflects a key topic with the highest degree of conceptual clarity, stimulating the readers' minds. In order to elicit an emotional or anticipated reaction from the audience, persuasive communication constantly prioritises the interest of the audience as its main focus.

Thus, a speech given to an audience "sells" one's ideas because it appeals to the readers' emotions, which produces the intended result since, in the end, the audience is persuaded and believes the particular notion.
