Q: A primigravida is in labor. Her per-vaginal examination revealed a posterior cervix with 5 cm cervical length, 1 cm dilatation, soft consistency, and head at -1 station. Calculate the Bishop score.

5. ***5*** - The Bishop score calculation: **cervical position** (posterior = 0), **cervical effacement** (5 cm length = 0), **dilation** (1 cm = 1), **consistency** (soft = 2), and **station** (-1 = 1). - According to standard **Dutta textbook** references, this totals to 5 points (0 + 0 + 1 + 2 + 1), with soft consistency correctly scoring 2 points. *3* - This score incorrectly assigns only **1 point for soft consistency** instead of the standard 2 points. - The miscalculation underestimates the **cervical readiness** for labor induction. *0* - A score of 0 would require all parameters to be at their **minimum values** (firm consistency, closed cervix, high station). - The given parameters show **1 cm dilation**, **soft consistency**, and **-1 station**, each contributing positive points. *8* - A high score of 8 indicates a **very favorable cervix** with significant effacement, anterior position, and greater dilation. - The current findings show **minimal effacement** (5 cm length), **posterior position**, and only **1 cm dilation**, inconsistent with such a high score.

Q: Identify the instrument given below.

Cusco's speculum. ***Cusco's speculum*** - This is a **bivalved, self-retaining speculum** with two articulated blades that open and close using a **thumbscrew/locking mechanism** at the handle. - Commonly used for **per speculum examination** to visualize the **cervix and vaginal walls** during gynecological procedures. *Sims' speculum* - A **single-bladed (univalve) speculum** that requires an **assistant to hold** during examination, unlike the self-retaining instrument shown. - Used to retract the **posterior vaginal wall** but lacks the dual-blade design visible in the image. *Graves' speculum* - Similar bivalved design to Cusco's but features **longer and wider blades** for better visualization in larger patients. - More commonly used in the **United States**, with a bulkier appearance than the instrument pictured. *Auvard's speculum* - A **weighted, self-retaining single-blade speculum** used as a **posterior vaginal retractor**. - Completely different design from the bivalved instrument shown, with only **one blade** and no locking mechanism.

Q: The following set of instruments are used for which procedure?

Pap smear. ***Pap smear*** - The image displays a complete set of instruments used for a **Pap smear**, including **glass slides** for sample collection, a **cervical brush**, a **spatula** (cytobrush and Ayre spatula), and a **speculum** to visualize the cervix. - These tools are specifically designed for collecting cervical cells to screen for **cervical cancer** and **precancerous changes**. *Biopsy* - A biopsy typically involves specialized instruments like **punch biopsy tools**, **forceps**, or needles to extract tissue samples, which are not depicted here. - While glass slides might be used for processing biopsy samples, the primary collection tools are absent. *Dilatation and curettage* - This procedure requires instruments such as **dilators** to open the cervix and **curetters** to scrape the uterine lining, which are not shown in the image. - The instruments shown are for surface cell collection, not for uterine cavity procedures. *Hysteroscopy* - Hysteroscopy uses a **hysteroscope**—a thin, lighted tube with a camera—to visualize the inside of the uterus. - The instruments in the image are for external examination and cervical cell collection, not for direct visualization of the uterine cavity.

Q: Which of the following is not a long-acting reversible contraceptive method?

Combined oral contraceptives. ***Combined oral contraceptives*** - While effective, **combined oral contraceptives** require daily adherence and are not typically classified as long-acting due to their need for frequent, consistent administration. - Their mechanism involves **exogenous hormones** that suppress ovulation and thicken cervical mucus, but their contraceptive effect relies on continuous daily intake. *Implanon* - **Implanon** (etonogestrel implant) is a **subdermal contraceptive implant** that provides effective contraception for up to three years. - It works by slowly releasing progestin, making it a **long-acting reversible contraceptive (LARC)**. *Copper T* - The **Copper T intrauterine device (IUD)** is a non-hormonal LARC that can prevent pregnancy for **up to 10 years**. - It acts by creating an inflammatory reaction in the uterus that is toxic to sperm and eggs, preventing fertilization. *Depo-Provera injection* - The **Depo-Provera injection** (medroxyprogesterone acetate) is a progestin-only contraceptive given every **3 months**. - While it offers extended protection, it is **not universally classified as a LARC** by major guidelines (WHO, ACOG, CDC), which typically reserve this designation for IUDs and implants that do not require regular clinic visits.
