The Gloves and the Lion from Treasure Chest- other set of questions for class 10 poem the gloves and the lions by leigh hunt 7.03 Patients with Infectious Disease The center adheres to infection control policies to ensure the safety of patients, physicians, and staff members. Patients who are currently being treated for an infectious disease or condition that is transmitted via the contact route may not be treated at the center. Patients with disease spread via droplet (e.g. influenza) or airborne (e.g. tuberculosis, measles) routes will reschedule their procedures in consultation with their physicians. The infection control nurse, in consultation with the infection control consultant, will determine whether the patient requires isolation or other additional precautions. If a patient with current Clostridium difficile-associated diarrhea is treated at the center, all rooms where the patient was housed, even briefly, should be cleaned by housekeeping under supervision of the staff at the center. Physicians must document relevant information in their pre-admission documentation. Standard Precautions will be followed in the care of all patients. Cigarroa Interventional Institute establishes policies to ensure compliance with infection control policies for the care of patients with drug-resistant organisms. The physician will screen patients through the medical history review prior to scheduling a patient at the center. During the pre-operative (pre-op) phone call or interview, a pre-op screening of the patient will be conducted. Strict isolation policies are required to treat patients with active MRSA, VRSA, or tuberculosis. Since this facility has no provisions for strict isolation, those patients with active infections will be referred elsewhere for treatment. Patients who are undergoing or completed a course of antibiotic therapy, are colonized and/or are not actively infected may be treated at the center. Patients with active infections requiring transmission-based precautions are not appropriate candidates for this facility and will be referred to another facility or rescheduled. Procedures cannot be scheduled for patients currently undergoing an infection with transmission based precautions. The patient must finish the course, and they will be rescheduled. Definitions and Standards: The following definitions and standards are provided for informational purposes only: Airborne Transmission and Precautions: This mode of transmission occurs by the spreading of either airborne droplet nuclei (small particle residue of 5 microns or smaller), of evaporated droplets which contain microorganisms that remain suspended in the air for long periods of time) or dust particles containing microorganisms. Patients must be isolated in private rooms with special air handling and ventilation, and the door must remain closed. Patient transport should be restricted to essential transport only. Respiratory precautions must be taken when in the presence of patients with active tuberculosis, including respiratory masks. Droplet Transmission and Precautions: Droplets are transmitted from the host source by coughing, sneezing, talking, or during procedures such as suctioning or bronchoscopy. Patients must be isolated, and a distance of 3 feet maintained between the infected patient and others. Caregivers within 3 feet of the patient should wear a mask. Patient transport should be minimized. Contact Transmission and Precautions: Direct contact transmission involves direct body surface to body surface contact with physical transfer of microorganisms between a susceptible host and an infected person. Indirect contact transmission involves contact with an intermediate object (usually inanimate) and a susceptible host. Patients should be isolated as much as possible. Gloves and hand washing are essential for all contact with the patient and contact with objects, which come in contact with the patient. Gloves should be changed after each contact. Reportable Condition If the patient is determined to have a reportable condition at any time during pre-admission, the Director of Operations/Nurse Manager will be notified. The procedural physician will be contacted and the case will be canceled. The Department of Health will also be notified the same day following state regulations regarding Reportable Communicable Diseases. To report a disease or condition, contact: The City of Laredo Epidemiology 24/7 Reporting Line: (956) 763-2915, if unable to report locally, call The Texas Departmrent of Health Services epidemiology program: 24/7Number for Immediately Reportable – 1-800-705-8868Yard Scenery Gladwin is sitting in the yard. She wears a pair of gloves and grey glasses. There are grapes and green grass around her. She is glad to enjoy the beautiful scenery. A solution is composed of a solute dissolved in a solvent. In the sugar water described in Figure 5-1, the solute was sugar and the solvent was water, and the solute molecules diffused through the solvent. It is also possible for solvent molecules to diffuse. In the case of cells, the solutes are organic and inorganic compounds, and the solvent is water. The process by which water molecules diffuse across a cell membrane from an area of higher concentration to an area of lower concentration is called osmosis (ahs-MOH-sis). Because water is moving from a higher to lower concentration, osmosis does not require cells to expend energy. Therefore, osmosis is the passive transport of water. Direction of Osmosis The net direction of osmosis depends on the relative concentra- tion of solutes on the two sides of the membrane. Examine Table 5-1. When the concentration of solute molecules outside the cell is lower than the concentration in the cytosol, the solution outside is hypotonic to the cytosol. In this situation, water diffuses into the cell until equilibrium is established. When the concentration of solute molecules outside the cell is higher than the concentration in the cytosol, the solution outside is hypertonic to the cytosol. In this situation, water diffuses out of the cell until equilibrium is established. Observing Diffusion Materials 600 mL beaker, 25 cm dialysis tubing, funnel, 15 mL starch solution (10 percent), 20 drops Lugol’s solution, 300 mL water, 100 mL graduated cylinder, 20 cm piece of string (2) Procedure 1. Put on your disposable gloves, lab apron, and safety goggles. 2. Pour 300 mL of water in the 600 mL beaker. 3. Add 20 drops of Lugol’s solution to the water. CAUTION: Lugol’s solution is a poison and eye and skin irritant. 4. Open the dialysis tubing, and tie one end tightly with a piece of string. 5. Using the funnel, pour 15 mL of 10 percent starch solution into the dialysis tubing. 6. Tie the other end of the dialysis tubing tightly with the second piece of string, forming a sealed bag around the starch solution. 7. Place the bag into the solution in the beaker, and observe the setup for a color change. Analysis What happened to the color in the bag? What happened to the color of the water around the bag? Explain your observations.

Under these conditions, water diffuses into and out of the cell at equal rates, so there is no net movement of water. Notice that the prefixes hypo-, hyper-, and iso- refer to the relative solute concentrations of two solutions. Thus, if the solution outside the cell is hypotonic to the cytosol, then the cytosol must be hyper- tonic to that solution. Conversely, if the solution outside is hypertonic to the cytosol, then the cytosol must be hypotonic to the solution. Water tends to diffuse from hypo- tonic solutions to hypertonic solutions. How Cells Deal with Osmosis Cells that are exposed to an isotonic external environment usually have no difficulty keeping the movement of water across the cell membrane in balance. This is the case with the cells of ver- tebrate animals on land and of most other organ- isms living in the sea. In contrast, many cells function in a hypotonic environment. Such is the case for unicellular freshwater organisms. Water constantly diffuses into these organisms. Because they require a relatively lower concentration of water in the cytosol to function normally, unicel- lular organisms must rid themselves of the excess water that enters by osmosis. Some of them, such as the paramecia shown in Figure 5-2, do this with contractile vacuoles (kon-TRAK-til VAK-y ̄ ̄o ̄ ̄o-OL), which are organelles that remove water. Contractile vacuoles collect the excess water and then contract, pumping the water out of the cell. Unlike diffusion and osmosis, this pumping action is not a form of passive trans- port because it requires the cell to expend energy. Copyright © by Holt, Rinehart and Winston. All rights reserved.

This lowers the solute concentration in the cytosol, bring- ing it closer to the solute concentration in the environment. As a result, water molecules are less likely to diffuse into the cell. Most plant cells, like animal cells, live in a hypotonic environ- ment. In fact, the cells that make up plant roots may be surrounded by water. This water moves into plant cells by osmosis. These cells swell as they fill with water until the cell membrane is pressed against the inside of the cell wall, as Figure 5-3a shows. The cell wall is strong enough to resist the pressure exerted by the water inside the expanding cell. The pressure that water molecules exert against the cell wall is called turgor pressure (TER-GOR PRESH-er). In a hypertonic environment, water leaves the cells through osmosis. As shown in Figure 5-3b, the cells shrink away from the cell walls, and turgor pressure is lost. This condition is called plasmolysis (plaz-MAHL-uh-sis), and is the reason that plants wilt if they don’t receive enough water. Some cells cannot compensate for changes in the solute con-Let's Play Ball! Baseball is an exciting game that is played all around the world. Players hit a ball with a bat. When you learn the rules, you can play the game. What Is Baseball? Baseball is a game with two teams. A team has nine players. Baseball teams play in an open field. Players use a bat, a ball, gloves, and four bases. A pitcher on one team throws the ball to a catcher on the same team. A batter on the other team hits the ball with the bat. The batter runs to first base, second base, and third base. The runner scores one point if he or she reaches the fourth base– home plate. The Story of Baseball. People have played baseball for hundreds of years. Long ago, people from England brought ball games to America. The games were like baseball in many ways. Over time, people made new rules and the games became one game-baseball. Famous Fields. Baseball fans love the fields where their teams play. In Boston, the team plays at Fenway Park. It is the oldest ballpark in America. Wrigley Field is an old ballpark in Chicago. Teams played there over one hundred years ago. They still play there today. Famous Players. Many people think Babe Ruth was the best baseball player ever. He hit 659 home runs with one team. He played for twenty-one years. Jackie Robinson is a hero. He was the first black baseball player to play on teams with white players. People look up to him for being a great athlete. Roberto Clemente played baseball with his team for eighteen years. He was really good at hitting the baseball. He scored 240 home runs for his team. Derek Jeter played baseball for twenty years. He scored 260 home runs for his team. People will always remember him as a great player. Everybody's Sport. Baseball time begins in the spring and goes until fall. Boys, girls, and grown-ups like to play and watch baseball. Many people think it is the best game in the world. Food and other form of poisoning - some substances when consumed can be dangerous to the health of human beings and can even cause death. Some substances are called poisons or toxins. Poisons can get into the body by swallowing, inhaling, by injection or via absorption through skin. Management of Food and Other Form of Poisoning • Ensure safety • If possible, find poison consumed • Avoid contact with the poison • Do not give drink or eatables • Do not induce vomiting • Arrange urgent transport to nearest healthcare facility Choking - Foreign body airway obstruction (FBAO) is one of the more common life-threatening emergencies that is seen and can be treated by the lay public. Management of Choking • Encourage to cough • Bend forward and give up to 5 back blows • Give 5 abdominal thrusts if still choking • Call for medical help Wounds are injuries that cause a break in the skin such as cuts, scrapes, or punctures. Management of Wounds • Wash hands or wear gloves if available. • Stop the bleeding by applying gentle pressure with a clean cloth or bandage. • Clean the wound using clean running water to remove dirt. • Apply antiseptic or antibiotic ointment if available. • Cover the wound with a clean bandage or gauze. • Observe for signs of infection such as redness, swelling, pain, or pus. • Seek medical help for deep, large, or heavily bleeding wounds. Hyperventilation is rapid or deep breathing often caused by anxiety, fear, or stress. Management of Hyperventilation • Stay calm and reassure the person. • Encourage slow, deep breathing through the nose and out through the mouth. • Ask the person to sit or lie down in a comfortable position. • Move the person to a quiet and well-ventilated area. • Loosen tight clothing around the neck or chest. • Do not give food or drinks during the episode. • Seek medical help if symptoms persist or the person becomes unconscious. Heat-related conditions include heat cramps, heat exhaustion, and heat stroke caused by exposure to high temperatures. Management of Heat-Related Conditions Move the person to a cool, shaded, or air-conditioned place. Loosen or remove tight clothing. Cool the body by fanning or applying cold compresses. Give cool water to drink if the person is conscious. Let the person rest in a lying position. Seek immediate medical help if there is confusion, fainting, vomiting, or very high body temperature.1.
