What can be the cause of weakened muscle and kidney functioning? A. Too little potassium B. Too much potassium C. Too little calcium D. Too much calcium Please select the best answer from the choices provided.
The Correct Answer and Explanation is :
The best answer is A. Too little potassium.
Explanation:
Potassium is an essential mineral and electrolyte that plays a critical role in various bodily functions, including muscle contraction, nerve transmission, and maintaining fluid balance. It is particularly important for the proper functioning of muscle cells, including those in the heart, and for maintaining kidney health.
- Weakened Muscles: A deficiency in potassium (hypokalemia) can lead to muscle weakness and cramps. This is because potassium is crucial for transmitting electrical signals in muscle cells. When potassium levels are low, the ability of muscles to contract effectively is impaired, leading to symptoms such as weakness, fatigue, and cramping. In severe cases, hypokalemia can cause paralysis.
- Kidney Function: The kidneys play a vital role in regulating potassium levels in the body. They filter excess potassium from the blood and excrete it in urine. If potassium levels are too low, it can affect kidney function as well. The kidneys also require an adequate amount of potassium to help maintain the body’s electrolyte balance and support the filtering processes. Chronic low potassium can lead to kidney issues over time, as the kidneys may struggle to maintain homeostasis.
- Comparison to Other Options:
- B. Too much potassium (hyperkalemia) can also weaken muscles and lead to serious heart issues, but the immediate concern in the context of muscle weakness and kidney function primarily stems from low potassium levels.
- C. Too little calcium can affect muscle contraction and bone health but is less directly tied to kidney function compared to potassium.
- D. Too much calcium (hypercalcemia) can cause muscle weakness and other issues, but again, it does not directly relate to the immediate concern of muscle and kidney function as clearly as low potassium does.
In conclusion, maintaining adequate potassium levels is essential for muscle strength and optimal kidney function, making option A the most appropriate choice.
