Why do onions cure bee stings?
Onions contain enzymes that break down proteins in bee venom, which can help reduce swelling and pain from a bee sting. Applying onion juice to a bee sting can also have a soothing and anti-inflammatory effect on the skin. However, individual experiences may vary and it's always best to seek medical advice if a bee sting reaction is severe.
What happens when you mix bleach and pepsi?
Mixing bleach and Pepsi can produce toxic fumes such as chlorine gas. This reaction can be dangerous and should be avoided as it can lead to respiratory problems, eye irritation, and other health issues. It's important to never mix bleach with any other household cleaner or product as it can result in hazardous chemical reactions.
Can a person breathe without having a pulse?
It is possible to have a pulse but no breathing as in asphyxiation, but the reverse is impossible, without a pulse you basically aren't alive, that pulse is a symbol of blood pumping through your body. Good answer above. I should add that, in some subjects, that pulse may be there but not be palpable.
Why anions and cations are important in the body?
Anions and cations are important in the body for maintaining balance and carrying out essential biological functions. Anions, such as chloride and bicarbonate, help regulate pH levels and facilitate nerve transmission. Cations, like sodium, potassium, and calcium, play critical roles in muscle contractions, nerve signaling, and fluid balance.
Exactly what your nose responds to as a scent I cannot say, but the reason that some things seem to smell more or further away has much to do with how much of the substance is in the air that you are breathing. Everything has a vapor pressure at any temperature above absolute zero. Vapor pressure is a way of stating how quicklya substance will become a vapor and thereby become airborne. Alcohol has a relatively high vapor pressure at any "normal" temperature and therefore is relatively quickly added to the air when a container of it is opened. Its molecules also are movingrelativelyfast (which is what causes a higher vapor pressure in the first place)and that means that its smell will travel quickly throughout an area.
What do you do for the prevention treatment or removal of burns?
If it is minor burn, treat the affected area by running tap for 10-20 minutes. Don't use ice as it could cause more damage to the skin. Take off the clothing, jewellery or watches near the burnt area. Don't cover the burnt area with anything sticky. Don't burst any blisters. If the burn is white, see a doctor straight away. Those are called deep burns.
Can fresh water immersion rehydrate a person through the skin?
No, fresh water immersion does not effectively rehydrate a person through the skin. Hydration typically occurs by drinking water to replenish the body's internal water stores. While soaking in water can soften skin and may provide some temporary relief from dryness, it is not a primary method of hydration.
What is a poisonous gas found in bleach?
Chlorine gas is a poisonous gas that can be released from bleach when it reacts with other chemicals, such as ammonia. Inhaling chlorine gas can cause coughing, chest tightness, and difficulty breathing, and can be extremely harmful to health. It is important to use bleach in a well-ventilated area and never mix it with other cleaning products.
What should people put in a survival kit for volcanoes?
Here are a few things you should have in your volcano eruption survival kit.
You should have several N 95 dust mask, a couple pair of safety goggles, a compass, water, water bottle with filter, food bar, and some emergency blankets.
You should also have a good flashlight and a emergency radio.
No, cactus thorns do not cause warts. Warts are caused by the human papillomavirus (HPV) infection, while cactus thorns are plant structures designed for defense and protection. If a cactus thorn pierces the skin, it may cause irritation or infection, but it will not lead to the development of warts.
A heat wave is an extended time interval of abnormally and uncomfortably hot and unusually humid weather. To be a "heat wave" such a period should last at least one day, but conventionally it lasts from several days to several weeks.
It is when the temperature becomes abnormally high, usually above 100 degrees.
Cocci bacteria are a type of bacteria that are commonly found on the skin and in various parts of the body. To effectively kill cocci bacteria, antibiotics prescribed by a healthcare professional are usually required. It is important to follow the prescribed treatment regimen to ensure complete eradication of the bacteria.
Dorsi flexion is the movement of bringing your foot up towards your knee. The opposite movement is planter flexion which is moving your foot away from your knee as if standing on your tip toes.
How do you find out the square centimeter for 5 x 4?
To find the area of a rectangle, multiply the length by the width. In the case of a 5 cm by 4 cm rectangle, the area would be 20 square centimeters.
If it is dimming the light, yes. A dimmer switch is nothing but a potentiometer, better explained as a variable resistor. It will lower the voltage going to the light bulb, but the excess energy must go someplace, and is released as heat. The lower the brightness, the warmer it will get (until it is turned all the way off).
There are newer dimmer switches that work in different manners, but I don't believe that is what you are referring to.
Indian Potato (Hedysarum alpinum, H. hedysaroides) Bear Root (Hedysarum mackenzii) Other Names: Eskimo potato, masru, Alaska carrot, licorice root (H. alpinum; H. hedysaroides); Wild sweetpea (Hedysarum mackenzii). Pea Family: (Leguminosae). Bear Root Physical Description: Hedysarum mackenzii (PICTURED ABOVE) a: grows to 2 1/2 feet; b: showy reddish-purple flowers that are arranged in clusters (racemes); c: pods (loments) are hairy, cross-veined, and have 3 to 8 joints; d: undersides of leaves are whitish and felty. Veins are hidden. Roots are inedible and can cause severe digestive upset. This species is regarded as poisonous. Indian Potato Physical Description: Hedysarum alpinum (PICTURED ABOVE) e: grows up to 2 1/2 feet; f: flower clusters are tapered and narrow at the top; g: pods are smooth and net-veined. H. alpinum pods have 1 to 3 joints; h: leaves are smooth; veins on underside are obvious. Roots are edible. Habitat and Range: Indian potato and bear root share similar habitats, namely gravel river bars, roadsides, rocky hillsides, and meadows. H. hedysaroides and H. alpinum are noted as edibles in the Hedysarum genus. Collectively they range from northern Alaska and the Yukon to British Columbia. Their range frequently overlaps with H. mackenzii, a species reported to be toxic. Species of unknown edibility, such as H. boreale(the Yukon to Oregon) and H. sulphurescens (British Columbia to Washington) also occur. Hedysarum: Genus to Be-A-Ware: Unlike many genera where some species are more tasty than others but all are harmless, the Hedysarums have distinct differences in safety. To harvest, you must be aware, noting subtle variations in leaf and flower structure between species. Foragers careless in identification are risking digestive disturbances. Though H. mackenzii isn't apt to be lethal, it is unsuited for human consumption. Athabascans refer to mackenzii as 'brown bear food.' Alaska's other Hedysarum species (alpinum/hedysaroides), however, are highly regarded for human use. Both H. alpinum and H. hedysaroides have smooth leaves with obvious veins on the underside of their leaves. H. hedysaroides has a shorter and darker colored flower cluster than alpinum. The top of the clusters in both are tapered, and narrower in appearance than H. mackenzii. Pods are smooth and net-veined. Harvest Calendar: Early spring or fall after frost for roots. The time of the harvest creates a problem for foragers. The plants are most easily and positively identified during the summer, precisely when the roots are dry and stringy. Foragers should mark a patch carefully, taking note as to whether any toxic bear root is present. In fall, when the foliage has died back and the roots are sweet, the forager can return and safely harvest. Natives, who rely heavily on this food source, can identify Hedysarum species simply by the appearance of the root. The 'bear food' tends to have shorter, less branched taproots. Food Use: Like garden parsnips, the roots of Indian potato are sweetened by frost. The plump fall or spring roots can be washed and eaten raw like carrots, grated into coleslaw, sliced and stir-fried, steamed as a dinner vegetable, simmered in stews, or added to boiled dinners. Try tatercakes when camping, serve them as a breakfast pancake, or as a supper potato substitute. Dena'ina Athabascans feed the softened roots to infants who lack mother's milk. The food is an important staple, which is stored in quantity in underground food caches. The Dena'ina refer to H. alpinum as k'tl'ila meaning "rope," an apt description of the root that grows to two feet long. H. mackenzii is ggagga k'tl'ina, which translates as "good food for bears." Interior Athabascans gather Indian potato in fall and store the roots, mixed wish fish oil and Rubus chamaemorus berries in cellars for winter use. Flora Kokrine, an Athabascan born in Tanana, Alaska, favors roots fried in oil. Elder Howard Luke of Nenana says he adds the roots to moose soup. Kobuk River Eskimos crush H. alpinum root, called 'masru' and use as butter. Roots are often taken from mouse holes and replaced with fish or other food. According to Inupiat teachings, masru should always be eaten with oil. Eating the root plain can cause constipation. del.icio.us Tags: indian_potato hedysarum_alpinumhedysarum_hedysaroides eskimo_potato_masrualaska_carrot licorice_root Hedysrum_alpinumwild_sweetpea hedysrum_mackenzii pea_familyleguminosae

What iv solution do you use to rehydrate an unconcious person?
Normal saline is usually used when the reason of unconsciousness is unknown. The use of fluids is limited to normal saline and ringers lactate, or lactated ringers is used for fluid replacement in the case of blood loss as it acts as a volume replacement, keeping the blood pressure up.
Why would you have hot water from all faucets except the bathtub faucet?
Are the lines to this bathroom connected? Follow the cold & hot water plumbing lines to the pipes which go to this bathroom. See if they are connected or if there are shutoffs on them and that they are turned on. If they are old galvanizd lines they could be plugged.
Can bathing in rubbing alcohol be the cause of acidosis?
Bathing in rubbing alcohol can lead to skin irritation, but it is unlikely to cause acidosis unless a significant amount is absorbed through the skin or ingested. Acidosis is usually caused by factors such as kidney disease, diabetes, or respiratory problems. If you are concerned about acidosis, it is important to consult a healthcare professional for a proper diagnosis and treatment.
Why is heat stroke primarily dangerous to people?
Heat stroke is primarily dangerous to people because it occurs when the body's temperature regulation system is overwhelmed, leading to a rapid increase in body temperature. This can result in organ damage and potentially be fatal if not treated promptly. People are more susceptible to heat stroke due to factors like age, underlying health conditions, and certain medications that can impair the body's ability to cool down effectively.
What is a secondary survey in first aid?
Secondary survey also known as secondary assessment is the process of discovering what has actually happened to the casualty and what injuries they have.
Secondary assessment is undergone after the primary assessments have been completed: (DR ABC- danger, response, airways, breathing and circulation) once it is clear that the casualty is breathing and whether they are conscious or not the secondary assessment can be underway.
from the head to the toes each part of the body is examined for bleeding, lumps and bumps, broken bones and deformities. As well as finding out about the physical injuries you should also look out for any medical alert bracelets which may state whether that person has an illness such as epilepsy; which in turn could be the reason for their collapse for example.
What are the primary survey of first aid?
'Can you hear me?', 'Open your eyes'
and gently shaking their shoulders.
If there is a response:
- If there is no further danger, leave the casualty in the position found and summon help if needed.
- Treat any condition found and monitor vital signs - level of response, pulse and breathing.
- Continue monitoring the casualty either until help arrives or he recovers.
If there is no response:
- Shout for help.
- If possible, leave the casualty in the position found and open the airway.
- If this is not possible, turn the casualty onto their back and open the airway.
This will move the casualty's tongue away from the back of the mouth.
Breathing- Look, listen and feel for no more than 10 seconds to see if the casualty is breathing normally.
- Look to see if the chest is rising and falling. Listen for breathing.
- Feel for breath against your cheek.
If the casualty is breathing normally, place them in the recovery position.
- Check for other life-threatening conditions such as severe bleeding and treat as necessary.
If the casualty is not breathing normallyor if you have any doubt whether breathing is normal begin CPR:
- CPR for adults
- If you have someone with you, send them to Dial 999 (or 112) for an ambulanceimmediately.
- If you are alone Dial 999 (or 112) for an ambulance immediately and then return to help the casualty.
- CPR for child/infant (one year to puberty)
- If you have someone with you, send them to Dial 999 (or 112) for an ambulanceimmediately.
- If you are on your own carry out CPR for 1 minbefore dialling 999 (or 112) for an ambulance.
- CPR for babies (birth to one year)
- If you have someone with you, send them to Dial 999 (or 112) for an ambulanceimmediately.
- If you are on your own carry out CPR for one min before dialling 999 (or 112) for an ambulance.
Why should you lie on your left side when unconscious and vomiting?
Lying on your left side helps prevent choking if you are unconscious and vomiting by allowing the vomit to flow out of your mouth, rather than block your airway. This position also helps reduce the risk of aspiration, where vomit enters your lungs.
