This shape allows them to have a larger surface area-to-volume ratio, which can be advantageous for nutrient uptake and diffusion. Coccus bacteria can occur in various arrangements, including single cells, pairs (diplococci), chains (streptococci), or clusters (staphylococci). This classification is important in identifying and categorizing different types of bacteria based on their morphology.

Engraving is not the method of choice for marking instruments. There are other methods such as etching, laser marking, or stamping that are commonly used for marking instruments. Therefore, the statement is false.

The word "para" means "beside or near".

The statement is true because paper-plastic pouch seals are designed to be tamper-evident. When the pouch is opened, the seal should destruct in a way that makes it impossible to reseal without leaving visible signs of tampering. This ensures the integrity of the contents inside the pouch and helps to prevent any unauthorized access or contamination.

The term "superheated steam" refers to steam that has been heated to a temperature above its boiling point. This means that all of the liquid water has been converted into steam, resulting in a dry steam with no moisture content. Superheated steam is often used in industrial processes where high temperatures are required, such as in power generation or heating systems. It is important to note that superheated steam is not the same as moist steam or steam at sea level, as these terms refer to steam with varying degrees of moisture content.

Some plastics, such as spun-bonded polyolefin, are designed to withstand low temperature sterilization processes. These processes involve using lower temperatures to sterilize equipment or products without causing damage to the plastic material. Therefore, the correct answer is "low" temperature.

A prefix is a word element added to the beginning of a word to change its meaning. It modifies the root element by adding a specific meaning or indicating a different context. This alteration of meaning allows for a more precise understanding of the word. Therefore, the statement that the purpose of a prefix is to alter or modify the meaning of the root element is true.

A combining vowel in medical terminology is used to enhance pronunciation. It is inserted between word parts to make the word easier to say and understand. By adding a vowel sound, it helps to separate and clarify the individual word parts, making it easier for medical professionals to communicate and understand the meaning of the term.

The pH scale measures the acidity or alkalinity of a substance, with values ranging from 0 to 14. A pH of 7 is considered neutral, while values below 7 indicate acidity and values above 7 indicate alkalinity. Therefore, a pH of 14 suggests the most alkaline condition, as it is the highest value on the scale.

The Spaulding Classification System is a widely accepted framework used to determine the level of disinfection or sterilization required for medical devices based on their intended use. It categorizes devices into three groups: critical, semi-critical, and non-critical. Critical items, such as surgical instruments that come into contact with sterile tissues or the vascular system, require sterilization. Semi-critical items, like endoscopes that come into contact with mucous membranes but do not penetrate body surfaces, require high-level disinfection. Non-critical items, such as stethoscopes, only require low-level disinfection. Therefore, the decision to sterilize or high-level disinfect a scope is indeed based on its use according to the Spaulding Classification System.

Mechanical recording charts/printouts are designed to provide a written record of sterilizer cycle activity. These charts or printouts can include information such as the temperature, pressure, and duration of the sterilization cycle. This record helps to ensure that the sterilization process has been properly conducted and can be used for quality assurance purposes. Biological tests and Bowie Dick tests are used to assess the effectiveness of the sterilization process, but they do not provide a written record of sterilizer cycle activity.

Paper-plastic pouches should not be labeled on the paper side of the pouch. This is because the paper side of the pouch is more susceptible to damage and moisture compared to the plastic side. Labeling on the plastic side ensures better protection and durability of the label, preventing it from smudging or getting damaged during storage or transportation.

Deionization is a system used to treat the final rinse water used for cleaning. It involves removing ions from the water, resulting in purified water that is free from impurities.

This temperature range is considered optimal for preserving the sterility and integrity of stored items, such as medical supplies or laboratory samples. Temperatures outside this range can potentially compromise the effectiveness and safety of these items. Therefore, it is important to ensure that the temperature in a sterile storage area remains within the recommended range.

Both gram-positive and gram-negative bacteria can develop spores. Spore formation is a survival mechanism that certain bacteria use to protect themselves from harsh environmental conditions. Spores are highly resistant structures that can remain dormant for long periods of time until favorable conditions for growth arise. This ability to form spores is not limited to a specific type of bacteria, but rather can be observed in both gram-positive and gram-negative bacteria.

This statement is false because items must be decontaminated before they are disinfected, not sterilized. Decontamination is the process of removing or reducing contaminants, such as dirt or microorganisms, from an object. Disinfection is the process of killing or inactivating microorganisms on an object. Sterilization, on the other hand, is the process of completely eliminating all forms of life, including microorganisms, from an object. Therefore, decontamination is a necessary step before disinfection, but not before sterilization.

A current asset is an asset that is expected to be used or converted into cash within one year. This includes assets like cash, accounts receivable, and inventory. By definition, current assets are expected to be utilized or liquidated in the short term, typically within one year from the balance sheet date. Therefore, the statement "A current asset is an asset that is expected to be used within one year" is true.

A perpetual inventory system is a system that continuously tracks and updates the quantities of supplies in storage in real-time. It provides accurate and up-to-date information about the inventory levels, allowing businesses to have better control over their stock and make informed decisions regarding ordering and reordering supplies.

Coaching is the correct answer because it involves using positive reinforcement to encourage employees to follow paper work practices and negative reinforcement to discourage inappropriate work practices. Through coaching, managers or supervisors provide guidance, support, and feedback to employees, helping them improve their performance and develop their skills. This approach focuses on training and mentoring employees to achieve their full potential and align their behavior with organizational goals. By utilizing positive and negative reinforcement techniques, coaching promotes a positive work environment and fosters continuous improvement.

The given statement is false because there are actually three parts to the ear: the outer ear, the middle ear, and the inner ear. The outer ear consists of the visible part of the ear and the ear canal, while the middle ear contains the eardrum and three small bones called ossicles. The inner ear is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain.

Bacteria that are often pathogenic to humans because they grow well at body temperature are called mesophiles. Mesophiles are microorganisms that thrive in moderate temperatures, typically between 20-45°C. Since the human body temperature falls within this range, mesophiles are able to grow and cause infections in humans. Thermophiles, on the other hand, prefer high temperatures and anaerobic bacteria do not require oxygen to survive. Therefore, mesophiles are the correct answer in this case.

Only 1% of microorganisms are harmful to humans because they can grow at approximately human body temperature. This means that the majority of microorganisms are not harmful and do not thrive at human body temperature.

The black handled scissors are designed to have the sharpest cutting edge. This is because black handled scissors are typically made from high-quality materials such as stainless steel or titanium, which can be sharpened to a very fine point. Additionally, the black color of the handle may indicate a non-stick coating or a special treatment that reduces friction, allowing for smoother and more precise cutting. Therefore, the black handled scissors are likely to have the sharpest cutting edge compared to the gold or silver handled ones.

The D-Value refers to the amount of time required to kill 90% of the microorganisms on an object. It is a measure of the effectiveness of a disinfection or sterilization process. TWA (Time-Weighted Average) is a term used in occupational health to represent the average exposure to a particular substance over a specific period of time. Exposure time, on the other hand, is a general term that refers to the duration of time that an object or individual is exposed to a particular condition or substance.

The correct answer is PEL (Permissible Exposure Limit). PEL represents the maximum allowable concentration of a chemical in the air that a worker can be exposed to over a specific time period, typically eight hours. It is a standard set by regulatory agencies, such as OSHA (Occupational Safety and Health Administration), to protect workers from the harmful effects of chemical exposure. TWA (Time-Weighted Average) is a method used to calculate the average exposure level over a specific time period, while OSHA is the regulatory agency responsible for setting and enforcing workplace safety standards.

PPM stands for parts per million and is a unit of measurement commonly used to describe the concentration or amount of a substance in the air. In the context of the question, PPM is the appropriate unit to measure the amount of ethylene oxide (EtO) in the air. TWA (Time-Weighted Average) and PEL (Permissible Exposure Limit) are not units of measure, but rather guidelines or standards used to assess and regulate exposure to hazardous substances. Therefore, PPM is the correct answer in this case.

Gauze squares should not be used as wicking material when basins are sterilized one inside another. The use of gauze squares as wicking material can potentially compromise the sterility of the basins. It is important to use appropriate sterilization techniques and materials to ensure that the basins remain sterile.

The Joint Commission requires preventive maintenance standards to be established for medical equipment. The Joint Commission is an independent, non-profit organization that accredits and certifies healthcare organizations and programs in the United States. They set standards and guidelines for healthcare facilities to ensure the quality and safety of patient care. One of their requirements is to establish preventive maintenance standards for medical equipment to ensure that it is regularly inspected and maintained to prevent malfunctions or failures that could potentially harm patients. OSHA (Occupational Safety and Health Administration) focuses on workplace safety, while AORN (Association of periOperative Registered Nurses) provides guidelines for perioperative nursing practice.

Ethylene oxide is known for its excellent penetration capabilities, making it an effective sterilization method for medical devices and equipment. It can easily penetrate small crevices, lumen, and packaging materials, ensuring thorough sterilization. On the other hand, ozone and hydrogen peroxide gas plasma may have limitations in terms of their ability to penetrate certain materials or reach inaccessible areas. Therefore, ethylene oxide is indeed superior to ozone and hydrogen peroxide gas plasma in terms of penetration capabilities.

Service recovery is the best approach for handling customer complaints because it focuses on resolving the customer's issue and restoring their satisfaction. This approach involves acknowledging the problem, apologizing for any inconvenience caused, and taking appropriate actions to rectify the situation. By addressing the complaint effectively, the company can not only retain the customer but also potentially turn them into a loyal advocate. Empowerment and uniform implementation of policies are important, but service recovery specifically addresses the resolution of customer complaints.

Viruses do not have flagella. Flagella are whip-like structures that are found in some bacteria and eukaryotic cells, such as sperm cells, that help with movement. However, viruses are much smaller and simpler than cells, and they do not possess any organelles or structures for movement. Instead, viruses rely on other mechanisms, such as hijacking host cells, to reproduce and spread. Therefore, the statement that a virus can move by means of its flagella is false.

In an ABC Inventory Control system:

"A" items are those with the largest dollar value but the smallest number of items. They are the most valuable items in the inventory and require close monitoring because they have a significant impact on the business's financial health.

Legal behavior is not solely defined as behavior relating to what is right or wrong. It is specifically defined as behavior that is in accordance with the law. While there may be overlap between legal behavior and what is considered morally right or wrong, they are not synonymous. Legal behavior is determined by the laws and regulations of a particular jurisdiction, whereas moral judgments are subjective and vary among individuals and cultures.

Liquid chemical sterilants that are labeled for use as both sterilants and high-level disinfectants require a longer contact time for sterilization. This means that in order to achieve sterilization, these chemicals need to be in contact with the items being sterilized for a longer period of time compared to when they are used for high-level disinfection. This is because sterilization involves the complete elimination of all microorganisms, including highly resistant spores, whereas high-level disinfection only requires the elimination of most microorganisms. Therefore, it is true that the use of these chemical sterilants as sterilants requires a longer contact time.

During instrument manufacture, the process of milking does not help build a protective chromium oxide layer on each instrument's surface. This statement is false.

False. Not all medical terms consist of each of the following word elements: prefix, root, and suffix. While many medical terms do contain these elements, there are also medical terms that may only have a root or a root and a suffix, depending on the specific term. Additionally, some medical terms may have a combining form instead of a prefix. Therefore, it is not accurate to say that all medical terms consist of each of these word elements.

The most efficient type of dry heat sterilizer is the mechanical convection sterilizer. This type of sterilizer uses a fan to circulate hot air evenly throughout the chamber, ensuring that all items are exposed to the same temperature. This results in a more rapid and consistent sterilization process compared to gravity convection sterilizers, which rely on natural air currents for heat distribution. Dynamic air removal sterilizers, on the other hand, are designed for sterilizing liquids and are not as efficient for dry heat sterilization.

The statement suggests that single-use items and their packaging decrease the amount of combustible materials in storage areas of a Central Service department. However, this is not true. Single-use items and their packaging actually increase the level of combustible loading in storage areas, as they add to the overall amount of combustible materials present. Therefore, the correct answer is false.

Ozone does not have the longest instrument turnaround time among the 3 major low temperature sterilants.

Aeration is not required for items sterilized in ozone sterilization processes. Ozone sterilization is a process that uses ozone gas to kill bacteria, viruses, and other microorganisms on surfaces. Unlike other sterilization methods, ozone breaks down quickly and does not leave any residue or require aeration. This makes it a convenient and efficient method for sterilizing items without the need for additional steps like aeration.

Manufacturers of new Class I devices do not need to obtain pre-market approval (PMA) from the FDA by submitting PMA applications with extensive test data to demonstrate the safety/effectiveness of their products. Class I devices are considered low risk and are subject to general controls, such as adherence to good manufacturing practices and proper labeling. Therefore, the statement that manufacturers of new Class I devices must obtain PMA from the FDA is false.

A failure mode and effects analysis (FMEA) is a proactive approach that looks forward to identify potential failure modes and their effects in order to prevent them from occurring in the future. It is a systematic method used to analyze and evaluate risks associated with a process, product, or system. By identifying and prioritizing potential failure modes, FMEA helps in developing strategies to mitigate or eliminate these risks before they cause harm or lead to failures. Therefore, the given statement is false as FMEA focuses on preventing future occurrences rather than looking backward at an event.
