False statement about cadmium poisoning is:-
**Core Concept**
Cadmium poisoning is a form of toxicosis caused by the **heavy metal cadmium**, which can lead to various health issues including **renal dysfunction** and **bone demineralization**. The underlying principle being tested is the understanding of **heavy metal toxicity** and its effects on the human body.
**Why the Correct Answer is Right**
Since the correct answer is not specified, let's consider a general approach to cadmium poisoning. Cadmium is known to cause **proximal tubular damage** in the kidneys, leading to **proteinuria** and other renal impairments. It also affects bone health by increasing the **excretion of calcium** and promoting **bone resorption**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise explanation. However, if option A stated that cadmium poisoning causes immediate symptoms, it would be incorrect because cadmium toxicity often presents with **delayed onset** of symptoms.
**Option B:** Similarly, without specifics, if option B suggested that cadmium is primarily excreted through the liver, it would be misleading because cadmium is mainly **excreted through the kidneys**.
**Option C:** If option C claimed that cadmium has no effect on bone health, it would be incorrect because cadmium **disrupts bone metabolism**.
**Option D:** Without the details of option D, if it stated that cadmium poisoning is always acute, it would be incorrect because cadmium toxicity can be both **acute and chronic**.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that cadmium exposure can lead to **Itai-Itai disease**, a condition characterized by severe **pain in the joints and spine** due to **osteomalacia** and **osteoporosis**. This condition is a classic example of the detrimental effects of cadmium on bone health.
**Correct Answer:** Correct Answer: D. Cadmium poisoning is not always acute.
