Semen analysis can be performed to:
- A.
Detect bladder infection.
- B.
Evaluate fertility status.
- C.
Identify cancerous cells.
- D.
Monitor prostate growth.
Correct Answer
B. Evaluate fertility status.Explanation
Semen analysis is a test that examines the quality and quantity of sperm in a man's semen. It is commonly used to evaluate fertility status by assessing various parameters such as sperm count, motility, and morphology. By analyzing these factors, doctors can determine if a man has any fertility issues that may be affecting his ability to conceive a child. The other options mentioned in the question, such as detecting bladder infection, identifying cancerous cells, or monitoring prostate growth, are not directly related to semen analysis and are not the primary purposes of this test.Rate this question:

A semen specimen is unlikely to be accepted for testing if it is:
- A.
Collected in a condom.
- B.
Collected on site.
- C.
In a sterile container.
- D.
Kept at 37C.
Correct Answer
A. Collected in a condom.Explanation
A semen specimen collected in a condom is unlikely to be accepted for testing because condoms are typically made of materials that can interfere with the analysis of the specimen. The latex or other materials used in condoms can release substances that may affect the accuracy of the test results or even cause damage to the sperm cells. Therefore, it is recommended to collect semen specimens in sterile containers specifically designed for this purpose to ensure the integrity of the sample and obtain reliable test results.Rate this question:

Which of the following fluids is obtained through lumbar puncture?
- A.
Amniotic
- B.
Gastric
- C.
Pleural
- D.
Spinal
Correct Answer
D. SpinalExplanation
Spinal fluid is obtained through a procedure called lumbar puncture, also known as a spinal tap. During this procedure, a needle is inserted into the lower back, into the spinal canal, to collect a sample of the cerebrospinal fluid (CSF). This fluid surrounds the brain and spinal cord, providing protection and nutrients. Lumbar puncture is commonly done to diagnose various conditions affecting the central nervous system, such as infections, bleeding, or certain neurological disorders. It can also be used to measure CSF pressure or administer medications directly into the spinal canal.Rate this question:

Which of the following is a type of serous fluid?
- A.
Gastric
- B.
Pleural
- C.
Seminal
- D.
Synovial
Correct Answer
B. PleuralExplanation
Pleural fluid is a type of serous fluid that is found in the pleural cavity, which surrounds the lungs. It helps to lubricate the surfaces of the pleura, reducing friction during breathing. Pleural fluid also plays a role in maintaining the pressure balance within the pleural cavity, allowing the lungs to expand and contract properly. The other options listed, gastric, seminal, and synovial, are not types of serous fluid.Rate this question:

Peritoneal fluid comes from the:
- A.
Abdominal cavity.
- B.
Lung cavities.
- C.
Pericardial sac.
- D.
Spinal cavity.
Correct Answer
A. Abdominal cavity.Explanation
Peritoneal fluid is a clear, watery fluid that fills the peritoneal cavity, which is located in the abdominal cavity. This fluid serves several important functions, including lubricating the organs and allowing them to move smoothly against each other. It also helps to protect the organs from friction and provides a medium for nutrient and waste exchange. The other options, such as lung cavities, pericardial sac, and spinal cavity, do not produce peritoneal fluid.Rate this question:

Fluid from joint cavities is called:
- A.
Pericardial fluid
- B.
Peritoneal fluid.
- C.
Pleural fluid.
- D.
Synovial fluid.
Correct Answer
D. Synovial fluid.Explanation
Synovial fluid is the correct answer because it is the fluid found in joint cavities. It acts as a lubricant and shock absorber, reducing friction between the bones and allowing smooth movement of the joints. Pericardial fluid is found in the pericardial cavity surrounding the heart, peritoneal fluid is found in the peritoneal cavity in the abdomen, and pleural fluid is found in the pleural cavity surrounding the lungs. None of these fluids are specifically related to joint cavities.Rate this question:
