PKD is abbreviated for which phrase?

• A. Polycystic kidney syndrome
• B. Polycystic kidney disorder
• C. Polycystic cystic kidney disease
• D. Polycystic kidney disease

Answer: (D)

PKD stands for Polycystic Kidney Disease. Abbreviations use the main nouns of a condition, so P comes from Polycystic, K from Kidney, and D from Disease. The other phrases don’t fit because they change the final term or add descriptors that don’t align with the PKD acronym (for example, using syndrome or disorder would point to different last letters, and adding cystic would not map to D). In medical practice, Polycystic Kidney Disease is the standard term, describing a hereditary condition where many cysts form in the kidneys.
