Infection Control: Precautions and Risks! Trivia Quiz

Hand hygiene is the single most important way of preventing the spread of infection because our hands come into contact with various surfaces and objects throughout the day, picking up germs and bacteria. By practicing good hand hygiene, such as washing hands with soap and water or using hand sanitizer, we can effectively remove these harmful microorganisms and reduce the risk of transmitting them to ourselves or others. Hand hygiene is a simple yet effective measure that can significantly contribute to preventing the spread of infections.

Healthcare workers who use or may be exposed to needles are indeed at an increased risk of needlestick injuries. This is because they handle needles regularly during procedures such as injections or blood draws, which can accidentally puncture their skin and cause injury. These injuries can lead to the transmission of bloodborne pathogens such as HIV, hepatitis B, and hepatitis C. Therefore, healthcare workers must follow strict safety protocols and use protective measures like gloves and safety devices to minimize the risk of needlestick injuries.

When a procedure requires the use of goggles to protect the eyes from potential splattering, it is necessary to also wear a mask to prevent splattering into the mouth and nose. A mask acts as a barrier, preventing any particles or substances from entering the respiratory system through the nose and mouth. This ensures overall protection and safety during the procedure.

The statement is true because the number of organisms on a surface can impact the effectiveness of decontamination methods. If there are a large number of organisms present, it can be more difficult for the decontamination process to completely eliminate them. Therefore, it is necessary to thoroughly clean surfaces before decontamination to minimize the number of organisms and increase the efficacy of the decontamination methods.

Wearing glasses alone does not provide sufficient protection for healthcare workers. Goggles or face-shields are necessary as additional personal protective equipment (PPE) to protect the eyes from potential exposure to infectious droplets or splashes. Glasses alone do not provide a complete seal around the eyes, leaving potential entry points for contaminants. Therefore, healthcare workers should wear goggles or face-shields in addition to glasses to ensure proper eye protection.

The three reasons why phlebotomists should wear gloves are: 1) Sterile gloves prevent healthcare workers from transmitting their own flora to the patient or patient specimen, reducing the risk of contamination. 2) Gloves prevent the transmission of microorganisms from one patient to another, helping to maintain a sterile environment. 3) Gloves also protect the phlebotomist from becoming infected with any pathogens that may be present in the patient's blood or bodily fluids. Wearing gloves is not just a part of the uniform, but a crucial safety measure in the healthcare setting.

Waterless hand antiseptics have the advantage of not requiring a sink because they are designed to be used without water. These products are typically alcohol-based and contain ingredients that kill germs and bacteria on the hands. They are convenient and can be used in situations where access to a sink is limited or not available, such as when traveling, camping, or in healthcare settings. Therefore, the statement is true.

The correct answer suggests that employers should take several steps to implement a program for needlestick prevention in the workplace. These steps include using improved engineering controls, analyzing injuries to identify hazards, ensuring proper training for workers, establishing reporting procedures, evaluating prevention methods, modifying hazardous work practices, and promoting safety awareness. The answer does not include firing employees right away after a needlestick, as this would not be an effective prevention measure.

The first step to take after an exposure incident is to flood the exposed area with water and clean any wound with antiseptic and water. This is important to remove any potential contaminants and reduce the risk of infection. Reporting the incident to a supervisor or appropriate safety officer should be done after the initial cleaning and treatment. Seeking immediate medical attention is also crucial, but it should be done after the initial cleaning and reporting of the incident.

The presence of organic and inorganic matter on surfaces prevents effective decontamination because it forms a barrier that hinders the disinfectant or sterilant from reaching and killing the microorganisms underneath. Additionally, the matter can react with the disinfectants or sterilants, forming new compounds that are now less effective at decontaminating. This reduces the potency of the disinfectant or sterilant and compromises its ability to eliminate harmful pathogens.

After an exposure incident, seeking immediate medical attention is crucial. This step is important because it allows for prompt evaluation and treatment of any potential injuries or infections resulting from the exposure. It is essential to prioritize one's health and well-being and address any potential risks or complications as soon as possible. Reporting the incident to a supervisor or appropriate safety officer is important but should be done after seeking medical attention. Flooding the exposed area with water and cleaning any wound with antiseptic and water is also important, but seeking medical attention takes priority to ensure proper care and assessment.

After an exposure incident, it is important to report the incident to a supervisor or appropriate safety officer. This step is crucial as it ensures that the incident is documented and appropriate actions can be taken to prevent any further harm or exposure. Reporting the incident also allows for a thorough investigation to take place, identifying any potential risks or hazards that need to be addressed. By promptly reporting the incident, necessary measures can be implemented to protect the individual and prevent similar incidents from occurring in the future.

Gowns used for isolation rooms should be fluid resistant to protect the wearer from any potential contamination. They should only be used once and then disposed of to prevent the spread of any infectious agents. The removal of gowns should be done inside out to minimize the risk of contamination. Airborne isolation rooms are not the only ones that require these precautions, as any isolation room has the potential for transmission of infectious agents.

The given answer lists a series of steps that health care workers should take to protect themselves and their fellow workers from needlestick injuries. These steps include avoiding the use of needles where safe and effective alternatives are available, helping employers select and evaluate devices with safety features, using devices with safety features provided by employers, avoiding recapping needles, planning for safe handling and disposal before beginning any procedure using needles, disposing of used needles promptly in appropriate sharps disposal containers, reporting all needlestick and other sharps-related injuries promptly, informing employers about hazards from needles observed in the work environment, participating in bloodborne pathogen training, and following recommended infection prevention practices, including hepatitis B vaccination.

The patient in protective isolation wears a mask during transport because it is not feasible or practical to have everyone in the hospital hallways wear a mask to protect the patient. This answer highlights the logistical challenges of ensuring everyone's compliance with wearing masks and acknowledges the limitations of implementing such a measure.

The given answer provides a comprehensive list of standard precautions that should be followed during the delivery of healthcare. These precautions include avoiding unnecessary touching of surfaces, washing hands with soap and water when visibly dirty or contaminated, using hand antiseptic when hands are not visibly soiled, decontaminating hands before and after direct contact with patients, decontaminating hands after contact with blood or body fluids, decontaminating hands after contact with a patient's intact skin, decontaminating hands when moving from a contaminated-body site to a clean-body site, decontaminating hands after contact with inanimate objects in the patient's vicinity, reviewing the efficacy of disinfectants, not wearing artificial fingernails, washing hands with soap and water if contact with spores is likely, removing gloves before decontaminating hands, using EPA-registered disinfectants, cleaning and disinfecting surfaces, wearing appropriate PPE, removing organic material from instruments/devices, placing high-risk patients in single-patient rooms, and offering masks to coughing patients during periods of increased respiratory infections.

Face-shields as PPE are necessary in situations where there is a risk of splattering blood or body fluids. They should be designed in a way that provides protection to the eyes and mouth. Additionally, they should cover the entire face to prevent any splattering from entering through the sides or bottom of the shield. Face-shields can also be used as a substitute for free-standing or movable shields that are placed between the worker and the work surface. However, they are not worn for recreational purposes or for aesthetic reasons.

Masks should be worn once and then discarded because they can become contaminated with particles from the environment or the wearer's respiratory secretions. The maximum time they can be worn for is 15-20 minutes due to moisture from breathing that can make the mask less effective. This moisture can create a breeding ground for bacteria and viruses, increasing the risk of infection. Therefore, it is necessary to change masks regularly to ensure proper protection.

The active ingredients in disinfectants are substances that have antimicrobial properties and can kill or inhibit the growth of microorganisms. Sodium hypochlorite, alcohol, phenols, iodophors, and quaternary ammonium compounds are all known to have disinfectant properties and are commonly used as active ingredients in disinfectants. Alcohols, in general, are effective disinfectants, so they can also be considered as active ingredients. However, citrus flavored products and honey are not typically used as active ingredients in disinfectants and do not have known antimicrobial properties.

Needlestick injuries can occur due to certain work practices such as recapping, transferring body fluids between containers, and failing to properly dispose of used needles in puncture-resistant sharps containers. Recapping a needle increases the risk of accidental needlestick injuries, as does transferring body fluids between containers without proper precautions. Failing to dispose of used needles in puncture-resistant sharps containers can also lead to injuries. Additionally, placing the needle into sharps intact immediately after a blood draw can increase the risk of accidental injuries.

The active ingredients in antiseptics are substances that have antimicrobial properties, meaning they can kill or inhibit the growth of microorganisms such as bacteria, viruses, and fungi. Alcohol is a commonly used active ingredient in antiseptics, as it can effectively kill a wide range of microorganisms. Iodine is another active ingredient that is effective against bacteria, viruses, and fungi. Benzalkonium chloride and chlorhexidine are both antiseptic agents that are effective against a broad spectrum of microorganisms. Hydrogen peroxide is a mild antiseptic that can help clean wounds and prevent infection. Sodium hypochlorite, also known as bleach, is a strong disinfectant but is not commonly used as an active ingredient in antiseptics.

The effectiveness of hand hygiene techniques depends on various factors such as the amount of antiseptic used, the frequency of hand hygiene, the duration of the hand cleaning procedure, the type of product used, the concentration and potency of the antiseptic, the number of microorganisms present, the presence of organic and inorganic material, the temperature, pH levels, bio-film formation, and the number of organisms. These factors collectively determine the ability of hand hygiene techniques to effectively eliminate or reduce the presence of harmful microorganisms on the hands.
