Prenatal Care Practice Questions

Q: A pregnant woman presents with an IUD in place, and the thread is clearly visible. She wishes to continue the pregnancy. What is the most appropriate next step?

Remove gently. ***Remove gently*** - When the **IUD thread is visible**, gentle removal is recommended if the woman wishes to **continue the pregnancy**, as this significantly reduces the risk of miscarriage and infection. - Leaving an **IUD in situ** during pregnancy increases risks of **septic miscarriage**, **preterm delivery**, and **chorioamnionitis**. *Leave the IUD inside* - Leaving an **IUD in place** during pregnancy increases the risks of **septic miscarriage**, **chorioamnionitis**, and **preterm labor**. - The presence of the IUD can also lead to **placental complications** and difficulties with fetal development. *MTP (Medical Termination of Pregnancy)* - MTP is an option for unintended pregnancies but is not the most appropriate first step when the patient explicitly **wishes to continue the pregnancy**. - MTP would be considered if the patient chose to terminate, but the question states she wants to continue. *Cesarean section* - **Cesarean section** is a mode of delivery and is not an appropriate initial intervention for an early pregnancy with an **IUD in situ**. - The removal of an IUD from an early pregnancy does not necessitate a cesarean section.

Q: A woman has been using oral contraceptive pills (OCP) for 5 months and has had amenorrhea for the last 6 weeks. What is the best method to calculate the gestational age in this case?

Crown-Rump Length (CRL) by Ultrasound (USG). ***Crown-Rump Length (CRL) by Ultrasound (USG)*** - For women with **irregular menstrual cycles**, unknown last menstrual period, or those on **hormonal contraceptives**, **early ultrasound measurement of CRL** is the most accurate method for gestational age determination. - CRL is most accurate between **6 and 14 weeks of gestation**, providing a precise estimate within 3-5 days. *Abdominal girth* - **Abdominal girth** is an unreliable and highly variable measure that is not used for accurate gestational age determination. - It is influenced by maternal body habitus, uterine fibroids, and amniotic fluid volume, making it imprecise. *280 days from Last Menstrual Period (LMP)* - This method (Naegele's rule) assumes a **regular 28-day menstrual cycle** and ovulation on day 14, which is not applicable for a woman on **oral contraceptive pills (OCP)** where ovulation is suppressed. - The use of OCPs alters the hormonal profile, generally causing **amenorrhea or withdrawal bleeding** that does not reflect a true ovulatory cycle. *256 days from Last Menstrual Period (LMP)* - This calculation is not a standard or recognized method for determining **estimated date of delivery (EDD)**. - The standard calculation from LMP uses **280 days (40 weeks)** for a full-term pregnancy.

Q: A pregnant woman comes for a routine antenatal checkup. She had a history of a twin pregnancy one year ago. What is her gravida and para status?

G2P1. ***G2P1*** - **Gravida (G)** refers to the total number of confirmed pregnancies, regardless of outcome. This current pregnancy is her second, making her G2. - **Para (P)** denotes the number of pregnancies that have reached viability (typically 20 weeks gestation or more), producing one or more fetuses. Her previous twin pregnancy, regardless of the number of babies, counts as one para event. *G2P3* - While G2 is correct (current pregnancy + previous twin pregnancy), P3 would imply three separate birth events beyond viability, which is not supported by the history of one twin pregnancy. - The number of babies born in a single pregnancy beyond viability does not increase the 'P' count; it refers to the number of pregnancies carried to term. *G2P2* - G2 is correct, but P2 would mean she had two separate pregnancies that reached viability. She only had one previous pregnancy that reached viability (the twin pregnancy). - The para count is determined by the number of deliveries, not the number of fetuses delivered. *G2P0* - While G2 is correct, P0 would mean she has never carried a pregnancy to the point of viability. - Her history clearly states a twin pregnancy one year ago, indicating a previous pregnancy carried to term, making P0 incorrect.

Q: The following cost-effective investigations are routinely recommended in the screening of antenatal mothers, EXCEPT:

Echocardiography for cardiac disease. ***Echocardiography for cardiac disease*** - **Echocardiography** is not a *routinely recommended* screening investigation for all antenatal mothers due to its cost and the relatively low prevalence of significant congenital heart disease requiring universal screening. - It is typically performed only if there are **specific risk factors** or suspicious findings suggesting cardiac pathology. *Blood sugar levels for GDM* - Screening for **gestational diabetes mellitus (GDM)** with blood sugar levels (e.g., glucose challenge test) is routinely recommended due to the potential maternal and fetal complications if untreated. - GDM is a common condition that can be effectively managed with early diagnosis, making screening a **cost-effective** preventive measure. *VDRL for syphilis* - Screening for **syphilis** using tests like VDRL (Venereal Disease Research Laboratory) is a standard and *routinely recommended* antenatal investigation. - Early detection and treatment of syphilis in pregnant women prevent serious adverse outcomes such as **congenital syphilis**, which can cause severe fetal morbidity and mortality. *Urine analysis for bacteriuria* - **Urine analysis** for **asymptomatic bacteriuria** is routinely recommended during pregnancy because untreated bacteriuria can lead to pyelonephritis, preterm labor, and low birth weight. - It is a simple, **cost-effective** test with significant benefits for maternal and fetal health.

Q: What is the normal cervical length?

3 cm. ***3 cm*** - The **normal cervical length** in a non-pregnant woman typically measures **3-4 cm**, with **3 cm** being the commonly cited average. - During pregnancy, cervical length is monitored via transvaginal ultrasound, and a length ≥3 cm is considered reassuring for pregnancy maintenance. - This measurement is crucial for assessing the risk of preterm labor and cervical incompetence. *10 cm* - A cervical length of **10 cm is anatomically impossible** and not consistent with normal female reproductive anatomy. - The entire uterus (fundus to external os) measures approximately 7-8 cm in a non-pregnant state, making 10 cm for cervix alone unrealistic. *5 cm* - While **5 cm is within the upper range** of normal cervical length, it is longer than the typical average. - Cervical length can vary between 3-5 cm in healthy women, but **3-4 cm is most commonly cited** as the standard reference. *7 cm* - A cervical length of **7 cm is longer than normal** and would be considered abnormally elongated. - This measurement approximates the entire uterine length (fundus to external os), not just the cervix.

Q: A 25-year-old woman presents with vulvar ulcers and inguinal lymphadenopathy. PCR testing is positive for HSV-2. She is 20 weeks pregnant. Which of the following is the most appropriate management?

Oral acyclovir with continued monitoring during pregnancy. ***Oral acyclovir with continued monitoring during pregnancy*** - **Oral acyclovir** is the recommended treatment for HSV-2 during pregnancy to manage acute outbreaks and prevent recurrence, as it is **safely used** throughout pregnancy. - Continued monitoring ensures the effectiveness of treatment and allows for adjustments as pregnancy progresses, especially regarding labor and delivery planning to prevent **neonatal HSV transmission**. *Topical acyclovir only* - **Topical acyclovir** has limited systemic absorption and is generally **less effective** for treating established outbreaks, especially with lymphadenopathy, compared to oral antivirals. - It does not significantly reduce the risk of future outbreaks or vertical transmission to the fetus. *Valacyclovir with planned cesarean delivery* - While **valacyclovir** is also an appropriate antiviral for HSV, a **planned cesarean delivery** is typically reserved for women with active genital lesions or prodromal symptoms *at the onset of labor* to prevent neonatal transmission. - Prophylactic cesarean delivery based solely on a mid-pregnancy diagnosis of HSV-2, without active lesions near term, is not indicated. *Immediate cesarean delivery* - **Immediate cesarean delivery** is not indicated at 20 weeks gestation, as the fetus is not viable and there's no immediate obstetrical emergency. - This option would also pose significant risks to both the mother and fetus without providing any benefit for managing HSV at this stage of pregnancy.

Q: A pregnant woman at 32 weeks gestation is diagnosed with gonorrhea. What is the most appropriate management approach?

Ceftriaxone 500 mg IM single dose. ***Ceftriaxone 500 mg IM single dose*** - **Ceftriaxone 500 mg IM** is the recommended first-line treatment for **uncomplicated gonorrhea** in pregnant women according to current CDC guidelines. - This dose is safe and effective during pregnancy and provides adequate coverage to eradicate *Neisseria gonorrhoeae*. - A **single intramuscular dose** is sufficient to treat the infection and prevent complications such as **ophthalmia neonatorum** and **disseminated gonococcal infection** in the neonate. *Defer treatment until post-partum* - Deferring treatment would put the fetus at significant risk for **ophthalmia neonatorum** and **disseminated gonococcal infection** during delivery. - Untreated maternal gonorrhea can also lead to **premature rupture of membranes**, **preterm labor**, and **chorioamnionitis**. - Prompt treatment is crucial to prevent these severe maternal and neonatal complications. *Amoxicillin-clavulanate for 7 days* - **Amoxicillin-clavulanate** is not effective against *Neisseria gonorrhoeae* due to widespread resistance. - This combination is more commonly used for bacterial infections like **otitis media**, **sinusitis**, or **urinary tract infections**. - It is not the recommended antibiotic for gonorrhea treatment. *Azithromycin 2g oral single dose* - While **azithromycin** is used in combination with ceftriaxone for **presumptive coinfection with chlamydia**, it is not recommended as monotherapy for gonorrhea due to increasing resistance. - A 2g oral dose can cause significant **gastrointestinal side effects** including nausea and diarrhea. - Monotherapy with azithromycin has unacceptably high failure rates for gonorrhea treatment.

Q: A pregnant woman at 32 weeks presents with recurrent bacterial vaginosis despite multiple treatments. She has history of preterm labor in previous pregnancy. Current symptoms include discharge and burning. Partner is untreated. Which management approach is most appropriate?

Extended oral clindamycin with probiotics. ***Extended oral clindamycin with probiotics*** - Given the **recurrent BV** and history of **preterm labor**, an extended course of oral clindamycin (or metronidazole) is the most appropriate management to eradicate the infection and reduce risk of preterm birth. - **Extended/suppressive therapy** (typically 10-14 days followed by twice weekly suppression) is recommended for recurrent BV in pregnancy, especially with preterm labor history. - **Probiotics** (particularly Lactobacillus) may help restore healthy vaginal flora and reduce recurrence, though evidence is mixed. - **Partner treatment is NOT routinely recommended** for BV as studies show it does not reduce recurrence rates. *Topical azole cream only* - **Topical azole creams** are used for fungal infections (candidiasis), not bacterial vaginosis. - This treatment would be **ineffective** against BV and would not address the serious risk of preterm birth. *Single dose metronidazole with observation* - A **single dose of metronidazole** is insufficient for recurrent bacterial vaginosis and does not provide adequate suppression. - Given the history of **preterm labor**, extended/suppressive therapy rather than mere observation is essential to prevent recurrence and complications. *Delay treatment until postpartum* - **Delaying treatment** is inappropriate and dangerous given the **recurrent BV** and history of **preterm labor**. - Untreated BV during pregnancy significantly increases the risk of **preterm birth**, premature rupture of membranes, and chorioamnionitis.

Q: A 23-year-old primigravid woman comes to the physician for an initial prenatal visit at 13 weeks' gestation. She has had episodic headaches over the past month. She has no history of serious illness. Her immunizations are up-to-date. Her temperature is 37°C (98.6°F) and pulse is 90/min. Repeated measurements show a blood pressure of 138/95 mm Hg. Pelvic examination shows a uterus consistent in size with a 13-week gestation. The remainder of the examination shows no abnormalities. Urinalysis is within normal limits. Serum creatinine is 0.8 mg/dL, serum ALT is 19 U/L, and platelet count is 210,000/mm3. Which of the following is the most likely condition in this patient?

Chronic hypertension. ***Chronic hypertension*** - The patient has **elevated blood pressure (138/95 mm Hg)** detected at her initial prenatal visit at **13 weeks' gestation**, which is **prior to 20 weeks**, a key diagnostic criterion for chronic hypertension in pregnancy. - Importantly, there are **no signs of proteinuria or other end-organ damage**, ruling out preeclampsia, and the early presentation points away from gestational hypertension. *Eclampsia* - Eclampsia is defined by the development of **grand mal seizures** in a woman with preeclampsia, which is absent in this patient. - It usually occurs after 20 weeks' gestation and involves more severe symptoms and complications than seen here. *High normal blood pressure* - **High normal blood pressure** (e.g., 120-129 / <80 mm Hg) is a lower range than the patient's readings of 138/95 mm Hg, which is clearly stage 1 hypertension. - This term does not accurately describe the patient's elevated blood pressure readings which meet diagnostic criteria for hypertension. *Gestational hypertension* - Gestational hypertension is characterized by **new-onset hypertension after 20 weeks of gestation** in the absence of proteinuria or other end-organ damage. - This patient's elevated blood pressure was noted at **13 weeks' gestation**, making gestational hypertension an unlikely diagnosis. *Preeclampsia* - Preeclampsia involves **new-onset hypertension after 20 weeks of gestation** with proteinuria or signs of end-organ dysfunction (e.g., elevated creatinine, transaminases, low platelets). - This patient is at **13 weeks' gestation** and has no proteinuria or other signs of organ compromise, ruling out preeclampsia.

Q: Which of the following is the most sensitive and specific test during antenatal check-up for a pregnant lady with family history of Thalassemia?

High performance liquid chromatography. ***High performance liquid chromatography*** - **HPLC** is considered the most sensitive and specific test for diagnosing thalassemia and other hemoglobinopathies due to its ability to accurately quantify different hemoglobin fractions. - It provides a detailed **hemoglobin profile**, allowing for precise identification of abnormal hemoglobins and accurate assessment of thalassemia carrier status. *P. smear and reticulocyte count* - A **peripheral smear** can show microcytic, hypochromic red blood cells, which are characteristic of thalassemia, but this finding is not specific. - A **reticulocyte count** can indicate increased red blood cell production, but it is a general indicator of hemolysis or bone marrow activity and not specific for thalassemia. *Hemoglobin electrophoresis* - **Hemoglobin electrophoresis** separates different hemoglobin types based on their electrical charge, which is useful for identifying hemoglobinopathies. - While it can detect abnormal hemoglobins, its resolution and quantitative accuracy are generally lower than that of HPLC, making it less sensitive for detecting subtle variations or quantifying small amounts of abnormal hemoglobin. *NESTROFT* - **NESTROFT** (Naked eye single tube red cell osmotic fragility test) is a screening test used to detect beta-thalassemia carriers by assessing red cell osmotic fragility. - It is a good, inexpensive screening tool but lacks the sensitivity and specificity of definitive diagnostic tests like HPLC, and positive results require confirmation with other methods.
