ПЕРЕВОД ПОЖАЛУЙСТА
If we catch a cold, have a splitting headache, have a clogged nose, cough, are running high temperature, we must go to the policlinic. First we come to the registry. The registry clerk on a duty asks our name, address, age and occupation He writes out several slips because several specialists will examine us. Some of them will listen to our heart and lungs, some will check up our kidneys, liver, stomach, eyesight, and hearing. The others will make our blood analysis, take our blood pressure and x-ray us. In case of sudden and severe illness or an accident calls are made to the first aid station. There the doctors are on duty all day long. There are many ambulances there. The ambulances are equipped with everything necessary to give the first aid. The patient can be transported to hospital. There he is taken to the reception ward first. After questioning and examination the doctor fills in the patient’s case history. Then the patient is given special clothes and is put to some ward for treatment. There are different departments in the hospital. They are: the surgical department, the therapy, and the department of infectious diseases. The doctors make their daily round there. They examine patients and prescribe different medicines and treatments. When a patient is completely cured, he is discharged from the hospital. Our district doctor sees his patients in consulting room 4. A nurse gives us a thermometer to take our temperature. We must keep it under an armpit. Last time my temperature was 37,9. The doctor asked what my trouble was. He offered me to sit down in a chair and strip to the waist. He felt my pulse. It was faint and accelerated. Then I had to lay on the examination couch and the doctor palpated my abdomen. He asked me from what diseases I suffered in my childhood. I suffered from scarlet fever. Now I felt dizzy and my body was damp with sweat. The doctor filled in my card and diagnosed the case as the flu. Then he wrote out a prescription for some medicines: pills, powders, drops, and mixture. He also advised me to take a scalding footbath, to put a hot water bottle to my feet, to have hot tea with raspberry jam. That would keep my fever down. The result of my x-ray examination and blood analysis was normal. I had the prescription made at the chemist’s. I followed the prescribed treatment to avoid complications. Every day I took a tablespoonful of mixture 3 times a day and some pills.
In two days I was better and in a week I recovered from my illness. I began to take care of myself. Now I go in for sports because sports make me strong, healthy and cheerful. Every day I do my morning exercises and have a cold rubdown to prevent myself from catching cold. There is a good proverb: An apple a day keeps the doctor away. That’s why I eat a lot of fruit and vegetables.
