CU-IUCD 380-A is effective up to?

Appeared in: Hariyana-CHO-2021

Explanation

The CU-IUCD 380-A is a second-generation, copper-releasing intrauterine device.
The number '380' refers to the surface area of copper (380 mm²), which is a key determinant of its effectiveness and longevity.
According to national family planning guidelines and manufacturer approval, the Cu-T 380A provides effective contraception for a period of 10 years.
The copper ions released by the device create an inflammatory reaction in the uterus that is toxic to sperm and ova, preventing fertilization.

Option A: A 5-year effectiveness period is associated with other types of copper IUDs, such as the Multiload Cu-375 or Nova T, not the Cu-T 380A.
Option C: A 1-year effectiveness period is characteristic of the older, progesterone-releasing IUDs like Progestasert, which require annual replacement.
Option D: A 7-year effectiveness period is often associated with some hormone-releasing IUDs, such as the levonorgestrel-releasing IUD (Mirena), which is approved for up to 7 years in some regions.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Effective duration of Intra-Uterine Contraceptive Devices (IUCDs) as background academic context rather than a clinical decision trigger.
Accurate knowledge of IUD lifespans is critical for patient counseling and family planning services to prevent unintended pregnancies due to expired devices.
Nurses must educate patients on the specific type of IUD they have received and its correct replacement date, documenting this clearly in the patient's record.
What if? If a patient with a Cu-T 380A presents at 11 years post-insertion and is still sexually active, the nurse's priority is to rule out pregnancy and counsel the patient on immediate replacement and the potential need for emergency contraception, as the device is beyond its approved effective lifespan.

How to Approach the Question

First, identify the specific medical device mentioned in the question: 'CU-IUCD 380-A'.
Recognize that this is a question of factual recall regarding contraceptive methods.
Access your knowledge base on different types of IUDs and their approved durations of effectiveness.
Differentiate the Cu-T 380A from other IUDs like Multiload, Nova T, or hormonal IUDs (Mirena, Progestasert), which have different lifespans.
Select the option that correctly states the approved effective duration for the Cu-T 380A, which is 10 years.
