What Do You Know About Clinical Biochemistry? Trivia Quiz - Quiz

Clinical Biochemistry is the division of laboratory medicine which is involved with the measurement of both natural and unnatural chemicals in blood, urine as well as several other fluids which are found in the body. The test results are very useful for diagnosing health problems, determining prognosis and properly guiding the therapy of a patient. This quiz is designed to test your knowledge regarding this division of medicine.

Questions and Answers

1.

Laboratory diagnostic process to obtain a result can be divided into how many phases?
- A.
  
  4
- B.
  
  5
- C.
  
  3
- D.
  
  2
Correct Answer
C. 3

Explanation
The laboratory diagnostic process can be divided into three phases. These phases include pre-analytical, analytical, and post-analytical phases. The pre-analytical phase involves specimen collection, transportation, and preparation. The analytical phase involves the actual testing and analysis of the specimen. The post-analytical phase involves result interpretation, reporting, and communication. These three phases are essential in ensuring accurate and reliable laboratory results.

2.

Which phase involves an individual's preparation for collection of the biological material?
- A.
  
  Second phase
- B.
  
  First phase
- C.
  
  Last phase
- D.
  
  Third phase
Correct Answer
B. First phase

Explanation
The first phase involves an individual's preparation for the collection of the biological material. This suggests that before any collection can take place, there needs to be a phase dedicated to preparing the individual for the process. Without this preparation phase, the collection of the biological material may not be successful or accurate.

3.

In other to prevent errors, when should blood be collected?
- A.
  
  After a fasting period
- B.
  
  In the evening
- C.
  
  During the day
- D.
  
  At dawn
Correct Answer
A. After a fasting period

Explanation
Blood should be collected after a fasting period in order to prevent errors. Fasting before a blood test helps to ensure accurate results by eliminating any potential interference from food or drink. When a person fasts, it allows the healthcare provider to measure certain substances in the blood without any external factors affecting the results. This is particularly important for tests that measure glucose, cholesterol, or triglyceride levels, as these can be influenced by recent meals. Therefore, collecting blood after a fasting period is crucial for obtaining reliable and accurate test results.

People whose food is rich in fats will have which of the following?
- A.
  
  Elevated serum triacylglycerol concentration
- B.
  
  Increased serum nitrogen substance concentration
- C.
  
  Reduced triacylglycerol concentration
- D.
  
  A & B
- E.
  
  B & C
- F.
  
  A & C
Correct Answer
A. Elevated serum triacylglycerol concentration

Explanation
People whose food is rich in fats will have an elevated serum triacylglycerol concentration. Triacylglycerols, also known as triglycerides, are a type of fat found in the bloodstream. When a person consumes a diet high in fats, their body will produce more triacylglycerols, leading to an increased concentration of these fats in the blood. This can be measured through a blood test, and elevated levels of serum triacylglycerols are often associated with conditions such as obesity, diabetes, and heart disease.

Protein-rich food leads to which of the following?
- A.
  
  Increased ammonia levels
- B.
  
  Decreased urea levels
- C.
  
  Increased insulin levels
- D.
  
  Increased phosphate levels
Correct Answer
A. Increased ammonia levels

Explanation
Protein-rich food leads to increased ammonia levels. When proteins are broken down in the body, ammonia is produced as a waste product. The liver normally converts ammonia into urea, which is then excreted in the urine. However, if there is an excessive intake of protein or if the liver is not functioning properly, ammonia levels can rise. This can be a sign of liver disease or kidney dysfunction. High ammonia levels can be toxic to the brain and can cause symptoms such as confusion, fatigue, and even coma.

6.

Which of the following makes the urine more alkaline?
- A.
  
  Meat
- B.
  
  Fat
- C.
  
  Protein-rich foods
- D.
  
  Fruits
Correct Answer
D. Fruits

Explanation
Fruits make the urine more alkaline because they contain citric acid, which is metabolized into bicarbonate ions in the body. Bicarbonate ions help to neutralize the acidity in the urine, making it more alkaline. This is beneficial for individuals who have urinary tract infections or kidney stones, as alkaline urine can help prevent the formation and growth of these conditions.

7.

Medium physical exertion increases which of the following?
- A.
  
  Insulin
- B.
  
  Fat
- C.
  
  Glucose
- D.
  
  Nitrogen
Correct Answer
C. Glucose

Explanation
During medium physical exertion, the body requires more energy to fuel the muscles. Glucose, a type of sugar, is the primary source of energy for the body. Therefore, during physical exertion, the body increases the production and release of glucose to meet the increased energy demand. This allows the muscles to work efficiently and perform the required tasks.

Rate this question:
8.

Which of the following is very difficult to control?
- A.
  
  Physical exertion
- B.
  
  Mechanical trauma
- C.
  
  Effect of drugs
- D.
  
  Effect of food
Correct Answer
C. Effect of drugs

Explanation
The effect of drugs can be very difficult to control because it depends on various factors such as the individual's metabolism, tolerance, and the specific drug being used. Different people may have different reactions to the same drug, and it can be challenging to predict or control these reactions. Additionally, drugs can interact with other medications or substances, further complicating their effects. Therefore, effectively managing and controlling the effects of drugs requires careful monitoring and individualized approaches.

Which of the following has strong reduction properties?
- A.
  
  Vitamin C
- B.
  
  Vitamin D
- C.
  
  Vitamin A
- D.
  
  Vitamin B
Correct Answer
A. Vitamin C

Explanation
Vitamin C has strong reduction properties because it is an antioxidant, meaning it has the ability to donate electrons to neutralize or reduce free radicals. Free radicals are unstable molecules that can cause damage to cells and DNA. Vitamin C helps to protect the body from oxidative stress by neutralizing these free radicals and preventing cellular damage. It also plays a crucial role in the regeneration of other antioxidants in the body, such as vitamin E.

10.

Which of the following is an uncontrollable factor before the biological material collection?
- A.
  
  Stress
- B.
  
  Food
- C.
  
  Biological rhythms
- D.
  
  Mechanical trauma
Correct Answer
C. Biological rhythms

Explanation
Biological rhythms refer to the natural cycles that occur in living organisms, such as sleep-wake cycles, hormone production, and body temperature fluctuations. These rhythms are internal and are controlled by the body's biological clock. Since they are a natural process and cannot be controlled by external factors, biological rhythms can be considered as uncontrollable factors before the collection of biological material.
