Trivia Flashcards

What could expose employees to bloodborne pathogens?

Answer: Needlestick and other sharps-related injuries

Bloodborne pathogens are infectious microorganisms found in human blood that can cause disease. Needlestick and other sharps-related injuries, such as accidental punctures from contaminated needles, scalpels, or broken glass, are the most common and direct routes of occupational exposure to these pathogens. These injuries create a pathway for infected blood to enter the bloodstream, posing a significant health risk.

For the majority of physically active persons, what is the suggested ratio of total calories from protein, fat, and carbohydrates?

Answer: no more than 30% fat, 10-15% protein, 55-60% carbohydrates

For most physically active individuals, a balanced macronutrient distribution is crucial for optimal energy, performance, and recovery. The suggested ratio emphasizes carbohydrates (55-60%) as the primary fuel source, moderate protein (10-15%) for muscle repair and growth, and limited fat (no more than 30%) for essential bodily functions and energy storage. This balance supports sustained activity and overall health.

What typical symptom aids in the diagnosis of an ACL injury?

Answer: A popping sound made at the time of injury

A distinct "popping" or "snapping" sound heard or felt at the exact moment of injury is a very common and significant symptom indicative of an Anterior Cruciate Ligament (ACL) tear. This auditory cue, often accompanied by immediate pain, swelling, and instability, serves as a strong diagnostic indicator that helps differentiate an ACL injury from other knee problems.

What are the normal consequences of an ACL injury?

Answer: a hit to the side of the knee, landing from a jump, hyper extending the knee, pivoting the knee, or a quick change in direction when running

ACL injuries commonly result from specific mechanisms that place excessive stress on the knee joint. These include a direct hit to the side of the knee (valgus stress), hyperextending the knee, landing awkwardly from a jump, or rapid pivoting and cutting movements during sports. Such actions can cause the ACL to tear, leading to instability and pain.

What kind of injuries do needles that unintentionally pierce the skin cause?

Answer: Needlestick injury

A needlestick injury specifically refers to an unintentional percutaneous (through the skin) puncture by a hypodermic needle. These injuries are a significant concern in healthcare settings due to the high risk of transmitting bloodborne pathogens. While "sharps injury" is a broader term, "needlestick injury" precisely describes the consequence of needles unintentionally piercing the skin.

How many extra calories should an athlete consume each day in order to gain weight?

Answer: 500

To achieve healthy weight gain, particularly for athletes aiming to build muscle mass, it is generally recommended to consume a caloric surplus. Adding approximately 500 extra calories per day to one's diet is a common guideline. This consistent surplus typically results in a gradual weight gain of about 1 pound per week.

Is the hepatitis B virus contagious when it comes into direct touch with bodily fluids like blood from an infected person?

Answer: True

True. The Hepatitis B virus (HBV) is highly contagious and can be transmitted through direct contact with infected bodily fluids, including blood, semen, and vaginal fluids. This makes activities like sharing needles, unprotected sexual contact, or accidental needlesticks significant routes of transmission. HBV is a resilient virus that can survive outside the body for at least seven days and still cause infection.
