Primary Dysmenorrhea Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Primary Dysmenorrhea. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Primary Dysmenorrhea Indian Medical PG Question 1: All of the following occurs because of prostaglandin use except?
- A. Increased motility of bowel
- B. Nausea
- C. Excess water retention (Correct Answer)
- D. Flushes
Primary Dysmenorrhea Explanation: ***Excess water retention***
- **Prostaglandins** generally promote **diuresis** and natriuresis, meaning they help the body excrete water and sodium, rather than retain them [2].
- While some prostaglandins can affect renal blood flow, direct causation of **excess water retention** as a primary side effect is not typical.
*Flushes*
- **Prostaglandins**, particularly **PGE1** and **PGE2**, are potent **vasodilators** and can cause cutaneous vasodilation, leading to **flushing** and a sensation of warmth [3].
- This effect is often mediated by the relaxation of vascular smooth muscle.
*Increased motility of bowel*
- Many **prostaglandins**, especially **PGE** and **PGF** series, stimulate **smooth muscle contraction**, including in the gastrointestinal tract [1].
- This increased contraction can lead to **enhanced bowel motility**, sometimes causing diarrhea or abdominal cramping [1].
*Nausea*
- **Prostaglandins** can have various systemic effects, and activation of pathways in the central nervous system or direct irritation of the GI tract can lead to symptoms like **nausea** and vomiting [1].
- This is a common side effect, especially with systemic administration.
Primary Dysmenorrhea Indian Medical PG Question 2: Which of the following is NOT a cause of metrorrhagia?
- A. Polyp
- B. CA endometrium
- C. IUD
- D. Intramural fibroid (Correct Answer)
Primary Dysmenorrhea Explanation: ***Intramural fibroid***
- **Intramural fibroids** are located within the uterine wall and are **primarily associated with menorrhagia** (heavy or prolonged menstrual bleeding during regular periods) rather than metrorrhagia.
- Their main effect is to increase the endometrial surface area and impair uterine contractility, leading to **heavy regular menstrual flow**.
- While they can occasionally cause irregular bleeding if complicated by degeneration or severe distortion, this is **not their typical presentation**, making them the **least characteristic cause** of metrorrhagia among the given options.
*Polyp*
- **Endometrial polyps** are **classic causes of metrorrhagia** because their friable surface bleeds irregularly, especially with hormonal fluctuations or minor trauma.
- They commonly present with **intermenstrual spotting** and post-coital bleeding, making them a typical cause of irregular bleeding.
*CA endometrium*
- **Endometrial carcinoma** is a **frequent cause of metrorrhagia**, particularly in postmenopausal women, due to irregular shedding of friable malignant tissue.
- The abnormal vascular supply and tissue breakdown in cancer results in **unpredictable, irregular bleeding episodes** characteristic of metrorrhagia.
*IUD*
- **Intrauterine devices** are **well-known causes of metrorrhagia**, particularly copper IUDs, which cause endometrial irritation and increased prostaglandin release.
- Both copper and hormonal IUDs frequently cause **spotting and irregular intermenstrual bleeding**, especially in the first 3-6 months after insertion.
Primary Dysmenorrhea Indian Medical PG Question 3: Primary amenorrhea is defined as:
- A. Imperforate hymen exists
- B. None of the above
- C. Menstruation does not occur even after 15 years of age (Correct Answer)
- D. Menstruation does not occur even after 18 years
Primary Dysmenorrhea Explanation: ***Menstruation does not occur even after 15 years of age***
- Primary amenorrhea is defined as the **absence of menstruation by age 15** in individuals with normal secondary sexual characteristics.
- This definition is crucial for determining when to initiate investigation for underlying causes.
*Imperforate hymen exists*
- While an imperforate hymen can cause **cryptomenorrhea** (menstruation occurring but not flowing out), it is a specific cause of primary amenorrhea, not the definition itself.
- An imperforate hymen is identified by a **bulging, bluish membrane** at the vaginal introitus.
*None of the above*
- This option is incorrect because the first option accurately defines primary amenorrhea.
- The definition of primary amenorrhea is clinically well-established and widely accepted.
*Menstruation does not occur even after 18 years*
- This age cut-off is **too late** for the definition of primary amenorrhea, as investigations should ideally begin earlier.
- Delaying evaluation until age 18 could potentially delay the diagnosis and treatment of underlying conditions affecting fertility and overall health.
Primary Dysmenorrhea Indian Medical PG Question 4: A 16-year-old girl presents with cyclical pelvic pain every month. She has not achieved menarche yet. On examination, a suprapubic bulge can be seen in the lower abdomen. PR examination reveals a bulging swelling in the anterior aspect. What is the most likely diagnosis?
- A. Transverse vaginal septum
- B. Vaginal atresia
- C. Imperforate hymen (Correct Answer)
- D. Cervical agenesis
Primary Dysmenorrhea Explanation: ***Imperforate hymen***
- The combination of **cyclical pelvic pain** without menarche (primary amenorrhea) and a **suprapubic bulge** with **bulging swelling on PR examination** strongly suggests an imperforate hymen.
- This condition leads to the **accumulation of menstrual blood (hematocolpos)**, causing the observed swelling and pain.
- Imperforate hymen is the **most distal obstruction** of the female genital tract, presenting with a characteristic **bulging membrane at the vaginal opening**.
*Transverse vaginal septum*
- This condition also causes **primary amenorrhea** and **hematocolpos** leading to cyclical pain.
- However, a transverse vaginal septum is located **higher in the vagina** (not at the introitus) and would not typically present with such an obvious **bulging swelling on examination** at the vaginal opening.
*Vaginal atresia*
- **Vaginal atresia** involves the complete or partial absence of the vagina, which would prevent menarche and cause cyclical pain.
- While it results in hematocolpos (if the uterus is present), the presentation differs from the classic **bulging membrane** seen with imperforate hymen.
*Cervical agenesis*
- **Cervical agenesis** is the congenital absence or incomplete formation of the cervix, leading to **primary amenorrhea** and severe cyclical pain due to retained menstrual blood in the uterus (**hematometra**).
- This condition would not present with a **bulging mass on PR examination** at the vaginal level, but rather with an enlarged uterus above, as the obstruction is at the cervical level, not at the vaginal outlet.
Primary Dysmenorrhea Indian Medical PG Question 5: All of the following are true regarding after pains except:
- A. They become more pronounced as parity increases
- B. Most common in multiparous females
- C. Pain worsens when infant suckles
- D. Most severe on the 7th postpartum day (Correct Answer)
Primary Dysmenorrhea Explanation: ***Most severe on the 7th postpartum day***
- This is **INCORRECT** - afterpains are most severe immediately after delivery and typically resolve within **2-3 days postpartum**, not persisting until day 7.
- Afterpains rapidly decrease in intensity as the uterus involutes, with the most noticeable pain occurring in the first 24-48 hours.
- By the 7th postpartum day, the uterus has undergone significant involution, and afterpains have usually completely subsided.
*Most common in multiparous females*
- Afterpains are indeed more common and more severe in **multiparous women** because their uterine muscle tone is reduced after multiple pregnancies.
- The uterus requires stronger contractions to achieve involution, resulting in more noticeable afterpains.
*Pain worsens when infant suckles*
- When the infant **suckles**, it stimulates the release of **oxytocin** from the posterior pituitary.
- Oxytocin causes the uterus to contract more strongly, temporarily worsening afterpain.
- This mechanism is beneficial as it promotes uterine involution and helps prevent postpartum hemorrhage.
*They become more pronounced as parity increases*
- With each subsequent pregnancy (increased parity), the uterus loses tone and elasticity.
- This requires **stronger contractions** during involution to return to pre-pregnancy size.
- Therefore, multiparous women typically experience more pronounced and painful afterpains compared to primiparous women.
Primary Dysmenorrhea Indian Medical PG Question 6: A 28-year-old woman, G2 P1, with severe PPH unresponsive to oxytocin presents with hypotension and tachycardia. She has a soft uterus and ongoing bleeding. What is the next best step in management?
- A. IM carboprost (Correct Answer)
- B. Immediate hysterectomy
- C. Expectant management
- D. IV tranexamic acid
Primary Dysmenorrhea Explanation: ***IM carboprost***
- The **soft uterus** with ongoing bleeding despite oxytocin indicates **uterine atony** as the cause of PPH
- Carboprost (PGF2α) is the **standard second-line uterotonic agent** after oxytocin failure
- Effectively stimulates strong **uterine contractions** to control hemorrhage from the placental bed
- Given intramuscularly at **0.25 mg every 15-90 minutes** (maximum 8 doses)
- Contraindicated in active cardiac, pulmonary, or hepatic disease
*Immediate hysterectomy*
- Peripartum hysterectomy is a **last-resort surgical intervention** for refractory PPH
- Should only be performed after failure of medical management (all uterotonics) and conservative surgical options (uterine tamponade, uterine artery ligation, B-Lynch suture)
- **Too aggressive** as the immediate next step when second-line uterotonics haven't been tried
*Expectant management*
- **Completely inappropriate** for severe PPH with hemodynamic instability (hypotension, tachycardia)
- Ongoing bleeding from uterine atony requires **immediate aggressive intervention**
- Delays increase risk of hypovolemic shock, DIC, maternal morbidity, and mortality
*IV tranexamic acid*
- **Antifibrinolytic agent** that inhibits plasminogen activation, promoting clot stability
- WHO recommends administration **within 3 hours** of PPH onset as an adjunct therapy
- While useful in PPH management, it does **not address uterine atony** (the primary cause indicated by soft uterus)
- Should be given **in addition to uterotonics**, not as a substitute for definitive management of atony
Primary Dysmenorrhea Indian Medical PG Question 7: A 29 year old female presented with infertility. There is history of abdominal pain, dyspareunia, dysmenorrhea, menorrhagia. Most likely cause:
- A. Adenomyosis
- B. Endometriosis (Correct Answer)
- C. Cervicitis
- D. Myomas
Primary Dysmenorrhea Explanation: ***Endometriosis***
- The classic triad of symptoms in this 29-year-old female—**dysmenorrhea**, **dyspareunia**, and **infertility**—is highly suggestive of endometriosis.
- **Ectopic endometrial tissue** can cause chronic abdominal pain, menorrhagia, and inflammation, contributing to infertility.
*Adenomyosis*
- This condition involves the presence of **endometrial tissue within the myometrium**, leading to a thickened uterine wall.
- While it can cause dysmenorrhea and menorrhagia, **infertility** is not its primary presentation, and it is less commonly associated with severe dyspareunia compared to endometriosis.
*Cervicitis*
- **Inflammation of the cervix** typically presents with vaginal discharge, post-coital bleeding, or pelvic pain.
- It is not a common cause of primary infertility, severe dysmenorrhea, or dyspareunia as described.
*Myomas*
- Uterine **fibroids (leiomyomas)** are benign tumors that can cause heavy menstrual bleeding (menorrhagia), pelvic pressure, and sometimes infertility.
- However, they are less commonly associated with the triad of severe dysmenorrhea and dyspareunia as prominently as seen in endometriosis.
Primary Dysmenorrhea Indian Medical PG Question 8: The contraceptive choice for a 38 year old woman with chronic hypertension and history of dysmenorrhea and menorrhagia (malignancy ruled out) is:
- A. Copper intrauterine device
- B. Sterilization
- C. Combined oral contraceptive pills
- D. Levonorgestrel intrauterine device (Correct Answer)
Primary Dysmenorrhea Explanation: ***Levonorgestrel intrauterine device***
- The **Levonorgestrel IUD** is an excellent choice as it provides effective contraception while also treating menorrhagia and dysmenorrhea due to its local progesterone release.
- It is safe for women with **hypertension** as it is a **non-estrogen-containing method**, avoiding the increased risk of thrombotic events associated with estrogen.
*Copper intrauterine device*
- While an effective non-hormonal contraceptive, the **copper IUD** can worsen **dysmenorrhea** and **menorrhagia**, which are existing concerns for the patient.
- It does not offer any therapeutic benefits for her heavy and painful periods.
*Sterilization*
- Although it provides permanent and highly effective contraception, **sterilization** does not address the patient's symptoms of **dysmenorrhea** and **menorrhagia**.
- It is an irreversible procedure and typically considered when no further childbearing is desired and symptomatic relief is not a primary concern for the contraceptive method itself.
*Combined oral contraceptive pills*
- **Combined oral contraceptive pills (COCs)** are generally contraindicated or used with caution in women with uncontrolled **hypertension** due to the estrogen component, which can increase the risk of cardiovascular events, including thrombosis.
- While COCs can improve dysmenorrhea and menorrhagia, the cardiovascular risks in a 38-year-old with chronic hypertension outweigh these benefits.
Primary Dysmenorrhea Indian Medical PG Question 9: A 15-year old unmarried girl comes with history of dysmenorrhea. Age of menarche is 12 years. Per abdominal and per rectum examination reveal nothing abnormal. You will treat the patient with :
- A. Reassurance and giving antispasmodics throughout the month
- B. Hormones
- C. Antibiotics
- D. Reassurance and giving antispasmodics during menses (Correct Answer)
Primary Dysmenorrhea Explanation: ***Reassurance and giving antispasmodics during menses***
- The patient presents with **primary dysmenorrhea**, indicated by the onset of symptoms with menarche and normal pelvic examination findings in an unmarried girl.
- **Antispasmodics** (e.g., NSAIDs like ibuprofen or mefenamic acid) taken during menses effectively reduce pain by inhibiting prostaglandin synthesis, which causes uterine contractions.
*Reassurance and giving antispasmodics throughout the month*
- While **reassurance** is appropriate, taking antispasmodics throughout the entire month is **unnecessary** and can lead to adverse effects, as the pain is cyclical and directly related to menstruation.
- **Antispasmodics** are most effective when taken a day or two before the onset of menstruation and continued during the painful days.
*Hormones*
- **Hormonal therapy** (e.g., combined oral contraceptives) is a valid treatment option for dysmenorrhea, especially if non-steroidal anti-inflammatory drugs (NSAIDs) are ineffective or if contraception is also desired.
- However, for a 15-year-old unmarried girl with typical primary dysmenorrhea and no other complications, **NSAIDs/antispasmodics** are generally the first-line and usually sufficient treatment.
*Antibiotics*
- **Antibiotics** are used to treat bacterial infections, and there is no indication of infection (e.g., fever, unusual discharge, pelvic inflammatory disease) in this patient's presentation.
- Using antibiotics without an identified infection is inappropriate and contributes to **antibiotic resistance**.
Primary Dysmenorrhea Indian Medical PG Question 10: Which one of the following about primary dysmenorrhea is NOT true?
- A. Most commonly seen in adolescents and young women
- B. Pain is related to uterine hypoxia
- C. Pain increases following pregnancy and delivery (Correct Answer)
- D. Always confined to ovulatory cycles
Primary Dysmenorrhea Explanation: ***Pain increases following pregnancy and delivery***
- It is a common clinical observation that primary dysmenorrhea often **improves or resolves** after pregnancy and childbirth, likely due to cervical dilatation, changes in uterine structure, or altered innervation.
- Therefore, the statement that pain *increases* following pregnancy and delivery is **NOT true** and is the correct answer.
*Most commonly seen in adolescents and young women*
- This statement is **TRUE**. Primary dysmenorrhea typically begins within **6-12 months** after menarche once ovulatory cycles are established.
- It is **most prevalent in adolescents and women in their 20s**, though it can persist into later reproductive years.
- Incidence decreases with age and often improves after childbirth.
*Pain is related to uterine hypoxia*
- This statement is **TRUE**. The pain in primary dysmenorrhea is primarily caused by **excessive prostaglandin F2α production** during endometrial breakdown.
- Prostaglandins cause **intense uterine contractions** leading to **ischemia** and reduced blood flow (hypoxia) to the myometrium.
- This **uterine hypoxia** and ischemia are significant contributors to the painful cramps experienced.
*Always confined to ovulatory cycles*
- This statement is **TRUE**. Primary dysmenorrhea is intrinsically linked to **ovulatory menstrual cycles**.
- It involves prostaglandin production in response to progesterone withdrawal and endometrial breakdown, which **only occurs in ovulatory cycles**.
- Anovulatory cycles (common immediately after menarche) are typically **painless**.
