The 30-Second Exam Hall Shortcut: ⚡ IUD Category Master Match

⏱️ Save ~25 seconds

Non-medicated = Lippes loop (III); Cu-releasing = Multiload 375 (I); Hormone-releasing = LNG-20 (IV); Implants = Progestogens under skin (II)! Match: A-III, B-I, C-IV, D-II!

1 A. Non-medicated IUD: Lippes loop (III).
2 B. Copper releasing IUD: CuT, Cu7, Multiload 375 (I).
3 C. Hormone releasing IUD: Progestasert, LNG-20 (IV).
4 D. Implants: Progestogens alone or in combination with estrogen placed subcutaneously (II).
5 Matching order: A-III, B-I, C-IV, D-II -> Option (2) / B.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Classify Intrauterine Devices (IUDs)

IUDs are classified into three distinct functional categories: 1. Non-medicated IUDs: e.g., Lippes loop (A -> III). 2. Copper releasing IUDs: e.g., CuT, Cu7, Multiload 375 (B -> I). 3. Hormone releasing IUDs: e.g., Progestasert, LNG-20 (C -> IV).

Step 2

Classify Subcutaneous Implants

Progestogens alone or in combination with estrogen can also be used by females as injections or implants under the skin (D -> II). Their mode of action is similar to that of pills and their effective periods are much longer.

Step 3

Assemble Combination

A-III, B-I, C-IV, D-II matches Option (2).

Verdict & Scientific Reason:

Mismatches Hormone releasing IUD with Progestogens and Implants with LNG-20.

⚠️
Student Fallacy (Why candidates pick this trap): Mismatches Hormone releasing IUD with Progestogens and Implants with LNG-20.
4 (4)
✗ Incorrect
Verdict & Scientific Reason:

Mismatches Non-medicated IUD with Multiload 375.

⚠️

NTA Trap Alert: Multiload 375 vs LNG-20 Category

Confusing copper-releasing Multiload 375 with hormone-releasing LNG-20.

🛡️ How to avoid the -1 mark: Multiload has copper wires; LNG-20 releases levonorgestrel (a synthetic progestogen).

Core Scientific Principle Tested:

"These Intra Uterine Devices (IUDs) are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20)... Progestogens alone or in combination with estrogen can also be used as implants under the skin."
