In one sentence, describe what the following article is about: After the injured person is stabilized, it's time to immobilize the broken bone if you anticipate a wait of an hour or longer for emergency medical personnel. Immobilizing it can help reduce the pain and protect the broken bone from further injury caused by inadvertent movement. If you don't have proper training, don't try to realign the bone. Attempting to align broken bones improperly can lead to further damage to blood vessels and nerves, leading to potential bleeding and potential paralysis. Keep in mind that splints only work for limb bones, not those of the pelvis or torso. The best method of immobilization is to make a simple splint. Place a piece of stiff cardboard or plastic, a branch or stick, a metal rod, or rolled up newspaper/magazine on either side of the injury to support the bone. Tie these supports together firmly with tape, string, rope, cord, rubber tubing, leather belt, necktie, scarf, etc. When splinting a fractured bone, try to allow movement in the adjacent joints and don't secure it too tight allow appropriate blood circulation. Splinting may not be necessary if emergency services are coming right away. In this case, splinting may cause more harm than good if you don't have the appropriate training. Once the broken bone is immobilized, apply something cold (preferably ice) to it as soon as you can while you wait for the ambulance. Cold therapy has many benefits, including numbing the pain, reducing inflammation / swelling and reducing bleeding by causing the arteries to constrict. If you don't have ice handy, consider using frozen gel packs or bags of vegetables, but make sure to wrap anything cold in a thin cloth in order to avoid ice burn or frostbite. Apply ice for about 20 minutes or until the area is completely numb before removing it. Compressing it against the injury may help reduce swelling even more as long as it doesn't increase the pain. While applying the ice, make sure the broken bone is elevated in order to combat swelling and slow down bleeding (if applicable). Breaking a bone is very traumatic and painful. Fear, panic, and shock are all common reactions, but they can have negative consequences for the body, so they must be controlled. As such, calm yourself and/or the injured person by reassuring him that help is on the way and the situation is under control. As you wait for help, cover the person to keep him warm and hydrate him if they are thirsty. Keep talking to him to distract him from focusing on his injury. Signs of shock include: feeling faint / dizzy, pale complexion, cold sweats, rapid breathing, increased heart rate, confusion, irrational panic. If it looks like the person is in shock, lay him down with his head supported and elevate his legs. Keep him covered with a blanket or jacket, or even a table cloth if those things are not available. Shock is dangerous because blood and oxygen are routed away from vital organs. This physiological state, if left untreated, can ultimately cause organ damage. If the wait for emergency medical personnel is longer than an hour (or you anticipate it being a long wait), then consider taking / giving some medication, if you have any, to control the pain and make the wait more tolerable. Acetaminophen (Tylenol) is the painkiller most appropriate for broken bones and other internal injuries because it doesn't "thin" the blood and promote more bleeding. Over-the-counter anti-inflammatories such as aspirin and ibuprofen (Advil) are helpful for pain and inflammation, but they inhibit blood clotting, so they aren't a good idea for internal injuries such as broken bones. In addition, aspirin and ibuprofen should not be given to young children, because they may cause dangerous side effects.
Summary: Immobilize the broken bone. Apply ice to the injury. Keep calm and watch for signs of shock. Consider pain medication.

In one sentence, describe what the following article is about: The needle will have a cap on it when you push it onto the end of the syringe, or should if it's a fresh, clean needle. Push the needle down on the syringe so the needle stays on and won't come off. Take the cap off the needle and have it ready to draw fluid into the syringe. You won't be able to get medication into the syringe if you have the cap still placed over the needle. The aluminum cap protects the opening of the bottle and keeps the liquid from leaking out, such as if the bottle is tipped on its side or upside down. Use your fingernails to remove the cap. Never use a knife or sharp object because you will compromise the rubber cap and invite contamination. Before you do so, draw the same amount of air into the syringe as you want to draw from the bottle. This makes it easier for you to draw in the contents. Then, you can poke the needle into the rubber cap. The rubber cap will act as a vacuum to keep air out of the bottle, and when the needle is pushed through, this vacuum will not be disrupted. After you have pushed the air in your syringe into the bottle, raise the bottle up so that it is almost vertical above the syringe, and slowly pull back on the plunger. Draw the fluid into the syringe up to the desired amount. It's important to raise the bottle above the syringe to allow gravity to draw the fluid in, and so that you're not drawing in air instead. Lowering the bottle moves the liquid to the bottom (via gravity) and introduces the "air" component of the bottle. Removing the needle then ensures that liquid won't drip out. Store the bottle in a place where it's cool and dry and won't get damaged, like in a cooler or toolbox meant for storing your cattle medicating equipment. Flick your finger against the barrel for any bubbles that don't automatically float up. Slowly and carefully push the plunger to eject the air bubbles. This especially important if you are going to administer IM or IV injections.
Summary: Take a syringe and cap it with a needle. Remove the needle cap. Take a new bottle and remove the aluminum cap. Poke the needle through the rubber cap. Draw the medication into the syringe. Lower the bottle and slowly remove the needle. Place the bottle upright in a safe place for future use. Point the needle upwards to allow any air bubbles present to float to the top.

In one sentence, describe what the following article is about: The datum is an arbitrary starting point placed on one end of the see-saw. You can place the datum on one end of the see-saw or the other. Let's say the see-saw is 16 feet long. Let's place the datum on the left side of the see-saw, close to the first child. Let's say the children are each sitting 1 foot away from each end of the see-saw. The center of the see-saw is the midpoint of the see-saw, or at 8 feet, since 16 feet divided by 2 is 8. Here are the distances from the center of the main object and the two additional weights form the datum: Center of see-saw = 8 feet away from datum. Child 1 = 1 foot away from datum Child 2 = 15 feet away from datum
Summary:
Choose a datum. Measure the datum's distance from the center of the main object as well as from the two additional weights.
