TLE Practice Test

This question assesses understanding of plumbing system design and maintenance practices. Fixture shutoffs, also known as stop valves, allow for isolation of individual fixtures for maintenance or repairs without shutting off water to the entire building. Recognizing the importance of these components is crucial for efficient plumbing system management.

Excessive water consumption is not a good plumbing practice as it leads to wastage of water resources. Good plumbing practices involve efficient water use and include methods like gray water recycling, water conservation, and rainwater harvesting, which help in managing water sustainably.

Plumbing ventilation is designed to carry sewer gas out of the system and relieve pressure within the drainage pipes. This helps prevent harmful gases from entering the living spaces and ensures proper flow and functioning of the drainage system. The other options describe other functions or benefits of plumbing systems but not the primary purpose of ventilation.

A backflow preventer is a device that stops sewer gases and other contaminants from flowing back into the building. A trap is also used to create a water seal, but in this context, the backflow preventer specifically addresses the need to stop gases from entering. Unions connect pipes, and pumps move liquids, neither of which provide a seal against sewer gases.

An angle valve is often used in plumbing fixtures such as lavatories, sinks, and water closets to shut off water supply easily. It is placed near the fixture and allows for quick access to control water flow, making it ideal for stopping leaks. Globe valves are used for regulating flow, check valves prevent backflow, and gate valves are used for main water shut-offs.

PVC pipes commonly come in standard lengths of 10 feet, which is equivalent to about 3 meters. This standard length facilitates easier handling, installation, and fitting during plumbing projects.

The standard length for G.I. (galvanized iron) pipes is typically 6 feet. Knowing this length helps in estimating the number of pipes needed to cover a certain distance from a house to the main supply line.

Rouge, also known as blush, is specifically applied to the cheeks to add color and highlight the face's natural contours. Mascara is used for the eyelashes, lipstick for the lips, and eye shadow for the eyelids.

Implements are tools used in the manicure and pedicure process that are durable and need to be sanitized after each use. These include items like cuticle pushers, nail brushes, cuticle nippers, nail files, and orange wood sticks. Items like cotton, hand towels, and nail polish are not considered implements but materials or cosmetics.

Equipment refers to larger or more permanent items used in the manicure or pedicure process, such as a manicure pillow, chair, and finger bowl. Other items listed are implements or materials.

Nail art is the creative and artistic process of decorating and enhancing nails with various designs and techniques. It requires skill and expertise to achieve aesthetically pleasing results.

Adult fingernails generally grow at an average rate of about 1/8 inch per month. Nail growth rates can vary based on several factors, but they do not typically change drastically with the seasons.

Massage is generally contraindicated for individuals with high blood pressure or heart conditions as it can exacerbate these issues. It is important to consult with a physician before providing massage services to individuals with these or other medical conditions.

SPF lotion provides essential protection from the sun's harmful UV rays, which is important for someone frequently exposed to sunlight. Other products may offer different benefits but are not specifically designed for sun protection.

Face cream helps to moisturize and hydrate the skin, which can reduce the appearance of aging signs. Anti-aging creams are more specialized, but general face creams also provide essential hydration.

Tempo is crucial in facial manipulations as it helps create a relaxing experience for the client. Consistent and appropriate tempo contributes to the overall effectiveness of the relaxation process.

A beveled cut involves holding the shears at an angle to create a sloped, angled effect on the hair. This technique differs from other cutting styles like blunt or graduated cuts.

Starting at the nape of the neck is effective for removing tangles as it allows for a systematic approach to detangling, ensuring all hair is evenly and thoroughly addressed.

Circuit breakers for convenience outlets or general-purpose circuits typically have an ampacity rating of 20 amperes to provide adequate protection for household electrical systems.

A three-way switch is used to control an electrical circuit from two different locations, providing convenience in controlling lighting and other devices.

Compact fluorescent lamps (CFLs) are more energy-efficient compared to incandescent lamps and other types of lighting, making them ideal for energy conservation.

Connecting one line of the source to Terminal 1 of the load is a common practice in simple electrical connections.

In a parallel connection, the total resistance is reduced, resulting in the least amount of equivalent resistance compared to series connections.

A solar cell produces electric current when exposed to light.

The photoelectric effect refers to the emission of electrons from a substance when exposed to electromagnetic radiation.

Converting kilowatts to horsepower using the formula 1 kW = 1.341 Hp, the horsepower rating is 1.75 kW x 1.341 = 2.34 Hp.

Energy consumed is 100 W x 20 hours = 2,000 Wh or 2 kW. The cost is 2 kW x P3.00 = P6.00.

A surface type device extends beyond the wall surface and is visible.

Electrical plans for residential houses do not typically include a substation plan.

Lighting loads are typically protected by 15 A fuses, and appliance loads by 20 A fuses.

Margarine is often avoided in low-cholesterol diets due to its high trans fat content.

Planning meals to be expensive and entail high costs is not a principle of meal planning.

Ginataang mongo with dilis is considered a low-cost but nutritious dish.

Fat does not repair body tissues; this is a function of proteins.

Vitamins regulate physiological processes in the body.

A table d’hote menu offers a fixed price for a complete meal including multiple courses.

The step of removing the entrails from poultry is called evisceration.

Blanching involves briefly boiling vegetables and then plunging them into ice water to preserve color and texture.

CHON stands for carbon, hydrogen, oxygen, and nitrogen, which are the elements found in proteins.

Iron deficiency commonly causes anemia.

A plumber’s snake is a tool used to clear clogs in pipes, often with a hook or corkscrew end.

A plunger is used to unblock toilets by creating a seal and applying pressure.

A yoke vise securely holds pipes in place while they are being cut.

Excessive water consumption is not considered a good plumbing practice.

A septic tank receives and treats waste located below the gravity system's normal grade.

Toxic substances are those hazardous to human health.

Plumbing ventilation is designed to carry sewer gas out and relieve pressure from the drainage system.

A globe valve can be used to shut off water flow with a 90-degree turn, though an angle valve is more common for this purpose.

A coupling is used to join two lengths of pipes together.
