1. Make a ppt about first aid, environmental protection, common sense and chemicals, and divide it into several pieces.

Well, for primary school students, your content should be simple, and the examples should be obvious and easy to distinguish. As for first aid, it can be divided into some accidental injuries such as burns, abrasions, bumps and bites, as well as emergencies, earthquakes and fires.

; Common sense of life can be divided into outdoor and indoor parts.

; Environmental protection, this.

Tell them common sense, what to do, what not to do and how to do it. Tell them that they are not environmentally friendly, such as El Ni? o phenomenon. They don't understand and waste their emotions. Environmental protection is manifested in details. It is very important to establish awareness.

; For chemicals, this involves too much. It is enough to know about common cold medicines in daily life, but you can't remember too much. If it is an experimental class, it is enough to remember some commonly used drugs. Actually, remember that these drugs are secondary. The key is to let them remember how to deal with the accidental injury of drugs in an emergency, which is related to first aid. It seems a little messy.

Ha ha.

I see, that's all I can think of.

2. What matters should be paid attention to in drug safety?

Drugs should be stored in sealed and dark containers to maintain the maximum curative effect. Special labels should be attached to the medicine boxes/bottles to explain the storage conditions, such as "cold storage", "do not freeze", "dark" and "dark".

All medicines should not be stored in too humid places, let alone in the bathroom. No matter which doctor you go to see, you should inform yourself of the drugs you often use, including prescription drugs, over-the-counter drugs and traditional Chinese medicine.

Any adverse reactions caused by drug use should be carefully recorded. As long as you prescribe drugs, you must take them.

If you don't take medicine, you must let the doctor know about it. Prescription drugs, try to buy at the original pharmacy every time.

Pharmacists usually record every prescription and over-the-counter medicine. This record sheet is called "patient medication file", which is convenient for checking potential problems in the future.

Patients can also make similar records themselves, and they should inform the pharmacist every time they add new drugs. Always consult a doctor or pharmacist before using other drugs.

Take the medicine strictly according to the instructions. If in doubt, please consult a doctor or pharmacist.

If you have any abnormal symptoms after taking the medicine, you should inform your doctor or pharmacist immediately. Be sure to read the label before taking medicine, and don't trust your memory.

Don't share your medicine with others. The prescription is for you, and you can only use it yourself.

Don't use any medicine given to you by others, unless it is a prescription medicine specially prescribed for yourself. Always keep the label on the medicine bottle. If it is used up, throw it away with the bottle.

When pouring medicine from the bottle, the label must face up to prevent the liquid medicine from flowing onto the label. ? For liquid medicine, unless otherwise specified, shake the bottle before taking it.

If you move to another city, remember to ask the pharmacist to hand over the prescription drug records to the local pharmacist. Put the most important medical information in the bag, such as which drugs you are allergic to, which chronic diseases (such as diabetes) and special requirements.

No matter where you travel, you should put prescription drugs in the original medicine box/bottle.

3. What should I pay attention to before taking the medicine?

Pay attention to the following problems when using disinfectants.

(1) Drug concentration and action time Generally speaking, the higher the drug concentration, the longer the action time, the better the disinfection effect, but the greater the * * * to the tissue. If the concentration is too low and the contact time is too short, it is difficult to achieve the purpose of disinfection. Therefore, it is necessary to properly master the drug concentration and action time according to the characteristics of disinfectants and disinfection targets.

(2) The temperature of the disinfectant and the temperature and humidity of the disinfected articles are within an appropriate range. The higher the temperature, the better the disinfection effect. It is reported that the disinfection effect is enhanced with the increase of temperature 10℃ 1 ~ 1.

5 times, so disinfection is generally carried out at 15~25℃. (3) the content of organic matter in the environment. The disinfection effect of disinfectants is inversely proportional to the content of organic matter in the environment. If there are many organic pollutants in the disinfection environment, it will also affect the disinfection effect.

Because on the one hand, organic matter can cover up pathogens and play a protective role, on the other hand, it can reduce the combination of disinfection drugs and pathogens and reduce the role of disinfection drugs. (4) pH in the environment. The pH value in the environment has obvious influence on the efficacy of disinfection drugs. For example, the disinfection effect of acidic disinfectants in alkaline environment is obviously reduced.

The bactericidal effect of quaternary ammonium salt disinfectant containing surfactant is obviously enhanced with the increase of pH; Benzoic acid weakens in alkaline environment; Glutaraldehyde is stable in acidic environment, but its bactericidal ability is weak. 3% sodium bicarbonate, so that the pH value of its solution is 7.

5 ~8。 At 5 o'clock, the bactericidal activity is obviously enhanced, which can not only kill a variety of reproductive bacteria, but also kill bacteria with spores; The optimum pH value of gas-containing disinfectant is 5.

0 ~6。 0; Phenol, benzoic acid, etc. Those that act in molecular form will weaken or even disappear when the environmental pH value rises; However, the bactericidal effect of quaternary ammonium salt, chlorhexidine and dye drug methyl violet increased with the increase of pH.

(5) Antagonism of Disinfectants When two disinfectants are used together, their efficacy may decrease, which is determined by the physical and chemical properties of disinfectants. Therefore, farmers should try not to use two disinfectants at the same time, and two disinfectants with different properties should be used at intervals. Oxidants such as peracetic acid and potassium permanganate can react with reductants such as iodine tincture, which will not only weaken the disinfection effect, but also increase the toxicity to skin and mucosa.
