How can you creat Vitamin D in skin cells?
- A.
Influence of sunlight
- B.
Influence of activity
- C.
During sleeping
- D.
During eating
Correct Answer
A. Influence of sunlightExplanation
Exposure to sunlight is responsible for the creation of Vitamin D in skin cells. When the skin is exposed to sunlight, it triggers a reaction that converts a substance in the skin called 7-dehydrocholesterol into Vitamin D3. This inactive form of Vitamin D is then converted into its active form by the liver and kidneys. Therefore, the influence of sunlight is crucial for the production of Vitamin D in skin cells.Rate this question:

Calcitonin is a hormone that is responsible for inhibiting the release of calcium from the bone. It also reduces the activity of osteoclasts, which are cells that break down bone tissue. Additionally, calcitonin inhibits the activation of vitamin D in the kidney, which is necessary for the absorption of calcium. Finally, it also inhibits the reabsorption of calcium by the kidney.Rate this question:

Correct Answer
A. Sudden injuryExplanation
The most common fractures are those resulting from sudden injury. This means that fractures are most commonly caused by accidents or trauma that occur suddenly, such as falls, car accidents, or sports injuries. Fractures caused by sudden injury are more common than those caused by fatigue or pathologic conditions.Rate this question:

Identify the steps in the treatment and recovery process of a fracture.
- A.
Reduction
- B.
Immobilization
- C.
Restore function/rehab
Correct Answer
A. ReductionExplanation
Reduction is the first step in the treatment and recovery process of a fracture. It involves realigning the broken bones to their normal position. This can be done through manual manipulation or surgical intervention. Once the bones are properly aligned, the next step is immobilization. This is done by applying casts, splints, or other devices to keep the bones in place and prevent further movement. Immobilization helps in the healing process. Lastly, after the fracture has healed, the focus shifts to restoring function and rehabilitating the affected area. This may involve physical therapy, exercises, and other interventions to regain strength, flexibility, and mobility.Rate this question:

Where is the most common site of gout?
- A.
Big toe
- B.
Ankle
- C.
Knee
- D.
Heel
Correct Answer
A. Big toeExplanation
Gout is a form of arthritis that occurs when there is a build-up of uric acid crystals in the joints. The most common site for gout to occur is in the big toe joint. This is because the big toe joint is often subjected to more stress and pressure, making it more susceptible to inflammation and the deposition of uric acid crystals. Additionally, the temperature of the big toe joint is slightly lower than other joints, which further promotes the formation of crystals. Therefore, the big toe is the most common site of gout.Rate this question:
-
- 33.
The pathogenesis of gout resides in an elevation of _____ levels.
- A.
Serum uric acid
- B.
Purine
- C.
Salvage
- D.
Nucleic acids
Correct Answer
A. Serum uric acidExplanation
Gout is a form of arthritis caused by the buildup of uric acid crystals in the joints. The pathogenesis, or development, of gout is linked to elevated levels of serum uric acid. When there is an excess of uric acid in the blood, it can form crystals in the joints, leading to inflammation and pain. Therefore, maintaining normal levels of serum uric acid is crucial in preventing and managing gout.Rate this question:
