Sodium Phosphate and Topical Compounds

Which of the following metals is contraindicated in certain poisonings due to higher renal toxicities of their complexes?

It is safe to use certain treatments in cases of cadmium poisoning.

Name one metal that should not be treated with certain therapies due to the formation of more toxic complexes.

In poisoning cases involving __________, it is contraindicated to use certain treatments due to the increased renal toxicity of the resulting complexes.

Match the following metals with their contraindicated treatment consequences:

Sodium Phosphate

Contraindications: Sodium Phosphate is contraindicated in poisonings from iron, cadmium, or selenium due to the increased renal toxicity of the resulting complexes compared to the free metals.
Absorption: Poorly absorbed from the gastrointestinal tract.
Administration: Intravenous administration is typically conducted through slow infusion with isotonic sodium chloride or other electrolyte solutions.
Physical Properties: Colorless or white granular salt that effervesces in warm, dry air.
Solution Properties: Solutions are alkaline, with a 0.1 M solution exhibiting a pH of approximately 9.5. Freely soluble in water and very slightly soluble in alcohol.

Topical Compounds

Categorization: Classified based on actions:
- Protective agents
- Antimicrobial agents
- Astringent compounds
Action: Primarily target small blood vessels (smooth muscle) and are applied topically.
Astringent Action: Limited penetration, causing a mild antimicrobial effect and restricting blood flow without causing cell death.

This quiz covers the properties, contraindications, and administration routes of Sodium Phosphate, alongside the categorization and action of topical compounds. Key focus areas include absorption characteristics, physical properties, and specific uses of these compounds in therapy.
