Breastfeeding Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Breastfeeding. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Breastfeeding Indian Medical PG Question 1: What vitamin is significantly absent in breast milk?
- A. Vitamin D
- B. Vitamin K (Correct Answer)
- C. Vitamin C
- D. Vitamin A
Breastfeeding Explanation: ***Vitamin K***
- Breast milk contains **critically low amounts** of **vitamin K** (approximately 2-5 μg/L), making it the **most significantly absent** vitamin in breast milk.
- Newborns are at high risk for **Vitamin K deficiency bleeding (VKDB)**, which can be life-threatening.
- This deficiency is so critical that **prophylactic vitamin K injection** is routinely administered to **all newborns** at birth to prevent hemorrhagic disease.
- Vitamin K is essential for the synthesis of **clotting factors II, VII, IX, and X** in the liver.
*Vitamin D*
- While breast milk does contain **some vitamin D**, the levels are often **insufficient** to meet the infant's daily requirements (contains ~25-78 IU/L; infant needs 400 IU/day).
- However, it is **present in measurable amounts**, unlike vitamin K which is nearly absent.
- Infants are recommended to receive **vitamin D supplementation** starting soon after birth, especially if the mother has low vitamin D levels or limited **sun exposure**.
*Vitamin C*
- **Breast milk** contains adequate amounts of **vitamin C** (40-50 mg/L), which is sufficient for the infant's needs.
- Maternal diet typically provides enough vitamin C to ensure its presence in breast milk.
*Vitamin A*
- Breast milk is a **good source** of **vitamin A**, particularly in the form of **beta-carotene** and retinol.
- Vitamin A levels in breast milk are adequate for infant **vision development** and **immune function**.
Breastfeeding Indian Medical PG Question 2: A study is to be conducted to compare the fat content in the expressed breast milk of pre-term infants with that of term infants. Which study design is best suited?
- A. Longitudinal study
- B. Ambispective
- C. Case control
- D. Prospective cohort (Correct Answer)
Breastfeeding Explanation: ***Prospective cohort***
- Among the given options, a **prospective cohort study** is the most appropriate design for this comparative study.
- The study involves identifying two groups (mothers of pre-term vs. term infants) and **prospectively collecting breast milk samples** to measure and compare fat content between these groups.
- This design allows for **standardized data collection** moving forward in time, ensuring consistent measurement protocols for both groups.
- While this is essentially a comparative cross-sectional measurement, the prospective nature ensures proper sample collection and reduces recall bias.
*Case control*
- This design is used to compare **exposures** between those with and without an outcome (typically a disease).
- Fat content in breast milk is a **continuous biological variable**, not a disease outcome, making case-control design inappropriate.
- Case-control studies work backward from outcome to exposure, which doesn't fit this scenario where we're comparing groups defined by infant term status.
*Longitudinal study*
- While **prospective cohort** is a type of longitudinal study, this term is too broad and non-specific.
- Longitudinal studies involve repeated measurements over time, but this question asks for a specific study design for comparing two groups.
- Simply stating "longitudinal study" doesn't specify the comparative framework needed.
*Ambispective*
- An **ambispective (or ambi-directional) study** combines retrospective and prospective components, using existing historical data plus new follow-up.
- This design is unnecessary here as there's no indication of existing historical data to utilize.
- The study can be conducted entirely prospectively by identifying mothers and collecting fresh breast milk samples for analysis.
Breastfeeding Indian Medical PG Question 3: Basanti, a 29-year-old female from Bihar, presents with drug-sensitive tuberculosis. She delivers a baby. All of the following are indicated except:
- A. Administer INH to the baby
- B. Withhold breast feeding (Correct Answer)
- C. Separate the baby from mother immediately
- D. Ask mother to ensure proper disposal of sputum
Breastfeeding Explanation: ***Withhold breast feeding***
- For mothers with **drug-sensitive tuberculosis**, breastfeeding is **strongly encouraged** by WHO and CDC guidelines as the benefits far outweigh any theoretical risks.
- Tuberculosis is **not transmitted through breast milk**, and the nutritional and immunological benefits of breastfeeding are crucial for the newborn.
- With appropriate maternal treatment and **INH prophylaxis** for the baby, breastfeeding poses no significant risk and should **never be withheld**.
*Administer INH to the baby*
- **Isoniazid (INH) prophylaxis** for 6 months is the standard of care for newborns exposed to maternal tuberculosis.
- This protects the infant from potential infection via respiratory droplets while the mother is receiving treatment.
- After completing prophylaxis, BCG vaccination is given if tuberculosis is excluded.
*Separate the baby from mother immediately*
- **Immediate routine separation** is generally not recommended for drug-sensitive TB if the mother has been on appropriate treatment for at least 2 weeks and is clinically improving.
- **Rooming-in is encouraged** with respiratory hygiene measures (mask wearing, hand hygiene, covering mouth when coughing).
- Separation may be considered only for untreated or inadequately treated mothers, or those with multi-drug resistant TB.
*Ask mother to ensure proper disposal of sputum*
- **Proper sputum disposal** and adherence to respiratory hygiene are essential infection control measures.
- This reduces environmental contamination and protects healthcare workers, family members, and the newborn from infectious aerosols.
- This is a standard precaution for all tuberculosis patients regardless of drug sensitivity.
Breastfeeding Indian Medical PG Question 4: Best criterion for determining live birth in suspected infanticide cases?
- A. Presence of milk or food in stomach
- B. Evidence of external injuries
- C. Examination of umbilical cord changes
- D. Hydrostatic test (lung float test) (Correct Answer)
Breastfeeding Explanation: ***Hydrostatic test (lung float test)***
- The **hydrostatic test**, also known as the **lung float test**, is considered the most reliable criterion in forensic pathology for determining if an infant was born alive.
- A positive result (lungs float in water) indicates that the infant took at least one breath, suggesting **live birth**, as fetal lungs are solid and sink.
*Presence of milk or food in stomach*
- While the presence of milk or food indicates a period of survival after birth, it doesn't definitively prove **live birth** over stillbirth if the infant was fed immediately after a perimortem event.
- It also doesn't provide information about **respiration**, which is a key indicator of live birth.
*Evidence of external injuries*
- **External injuries** may indicate foul play or neglect, but they do not confirm that the infant was born alive.
- An infant could be **stillborn** and then subjected to injuries, or injuries could occur post-mortem.
*Examination of umbilical cord changes*
- **Umbilical cord changes**, such as desiccation or mummification, indicate the passage of time after birth but do not differentiate between **live birth** and **stillbirth**.
- These changes can occur even if the infant was stillborn, especially if there was an attempt to cut and tie the cord.
Breastfeeding Indian Medical PG Question 5: Congenital passive immunity is INADEQUATE in -
- A. Measles
- B. Mumps
- C. RSV (Respiratory Syncytial Virus)
- D. Pertussis (Correct Answer)
Breastfeeding Explanation: ***Pertussis***
- **Congenital passive immunity** against *Bordetella pertussis* is **most inadequate** among the listed infections.
- **Minimal transplacental transfer** of protective IgG antibodies occurs, and maternal antibodies decline rapidly in infants.
- Newborns have **virtually no protection** from maternal antibodies, making them highly susceptible to severe whooping cough.
- This is why **early vaccination at 6 weeks** is critical, unlike measles which can wait until 9-12 months.
*Measles*
- Maternal antibodies provide **excellent passive immunity** protecting infants for **6-9 months**.
- This robust protection is why measles vaccination is delayed until 9-12 months of age.
- Represents the **gold standard** of effective maternal antibody transfer.
*Mumps*
- Maternal antibodies provide **good passive immunity** in early infancy.
- Mumps in young infants is rare due to this maternal protection.
*RSV (Respiratory Syncytial Virus)*
- Maternal antibodies provide **limited but present** passive immunity.
- Unlike pertussis where protection is nearly absent, RSV maternal antibodies can **reduce severity** of illness.
- However, RSV remains a major cause of bronchiolitis in infants despite this partial protection.
- The key difference: RSV has **some** maternal protection (inadequate but present), whereas pertussis has **almost none** (most inadequate).
Breastfeeding Indian Medical PG Question 6: A poverty-stricken mother suffering from active tuberculosis delivers a baby. Which one of the following would be the most appropriate advice in her case?
- A. Breast feeding and BCG immunization
- B. Breast feeding and isoniazid administration (Correct Answer)
- C. Expressed breast milk and BCG immunization
- D. Stop feeds and isoniazid administration
Breastfeeding Explanation: ***Breast feeding and isoniazid administration***
- **Breastfeeding** is safe and encouraged for infants of mothers with active tuberculosis, as the benefits of breast milk (nutrition, antibodies) outweigh the minimal risk of TB transmission through milk.
- **Isoniazid (INH) chemoprophylaxis** for the infant provides additional protection in high-risk exposure settings, particularly when the mother has active pulmonary TB and close contact is inevitable.
- This approach represents a conservative strategy prioritizing immediate chemoprophylaxis in a poverty-stricken setting where follow-up may be challenging.
*Breast feeding and BCG immunization*
- **Breastfeeding** is beneficial and appropriate.
- **BCG immunization** at birth is the current standard recommendation per WHO and IAP guidelines for infants born to TB-positive mothers.
- However, in settings with very high exposure risk and uncertain follow-up, some protocols additionally recommend INH prophylaxis, making the first option more comprehensive for this specific scenario.
*Expressed breast milk and BCG immunization*
- Expressing breast milk offers no significant additional protection against TB transmission compared to direct breastfeeding.
- Direct breastfeeding has additional benefits for mother-infant bonding and is not contraindicated in maternal TB.
- While **BCG immunization** is appropriate, this option unnecessarily complicates feeding.
*Stop feeds and isoniazid administration*
- **Stopping breastfeeding** is not indicated and would deprive the infant of essential nutrition and passive immunity.
- Breastfeeding is not contraindicated in maternal tuberculosis.
- While **isoniazid administration** may be appropriate, cessation of feeding is an incorrect recommendation.
Breastfeeding Indian Medical PG Question 7: 4 day old breastfed neonate, otherwise well, term neonate presented with jaundice, on testing the bilirubin level was found to be 18 mg/dl. Which of the following is the best step of management?
- A. Stop breast feeding and do phototherapy
- B. Initiate exchange transfusion
- C. Start iv fluids and give phototherapy
- D. Start phototherapy and continue breast feeding (Correct Answer)
Breastfeeding Explanation: ***Start phototherapy and continue breast feeding***
- For a 4-day-old, otherwise healthy, term neonate with a bilirubin level of 18 mg/dL, **phototherapy** is the recommended initial treatment to lower bilirubin levels and prevent **kernicterus**.
- **Breastfeeding should be continued** as it is crucial for hydration and nutrition, and interruption is generally not needed unless the bilirubin levels are extremely high and unresponsive to phototherapy.
*Stop breast feeding and do phototherapy*
- **Stopping breastfeeding is usually not necessary** for a bilirubin level of 18 mg/dL in a healthy, term neonate, as the benefits of breast milk outweigh the risks associated with this level of jaundice.
- While **phototherapy** is appropriate, discontinuing breastfeeding can lead to complications such as dehydration and decreased milk supply.
*Initiate exchange transfusion*
- **Exchange transfusion** is typically reserved for much higher bilirubin levels (e.g., >25 mg/dL in a term neonate) or when there are signs of **acute bilirubin encephalopathy**, which are not present here.
- It is an invasive procedure with potential risks, making it unsuitable as a first-line treatment for this bilirubin level.
*Start iv fluids and given phototherapy*
- **Intravenous fluids** are generally not indicated for an otherwise well, breastfed neonate unless there are signs of significant dehydration, which is not mentioned in this scenario.
- While **phototherapy** is appropriate, routine IV fluid administration can lead to **fluid overload** and is not standard practice in uncomplicated neonatal jaundice.
Breastfeeding Indian Medical PG Question 8: A woman delivers a healthy baby with weight 2.2 kg at the time of birth. What measures are to be taken?
1. The baby should be exclusively breast fed for first six months
2. The vaccination with OPV and BCG should be delayed till the baby is 2.5 kg of weight
3. Baby should be kept with mother and kangaroo care to be given
Select the correct answer using the code given below:
- A. 2 and 3 only
- B. 1 and 2 only
- C. 1, 2 and 3
- D. 1 and 3 only (Correct Answer)
Breastfeeding Explanation: ***1 and 3 only***
- **Exclusive breastfeeding** for the first six months is crucial for **nutrition** and **immunity**, especially for low birth weight babies.
- **Kangaroo Mother Care (KMC)**, involving skin-to-skin contact, helps regulate the baby's temperature, promotes bonding, and supports weight gain in LBW infants.
*2 and 3 only*
- While **Kangaroo Mother Care (KMC)** is appropriate for this baby, the recommendation to delay vaccination is incorrect.
- **BCG vaccination** should be given at birth to babies weighing **≥2 kg** as per IAP guidelines, so a 2.2 kg baby qualifies for immediate vaccination.
*1 and 2 only*
- **Exclusive breastfeeding** is appropriate, but delaying vaccinations is not indicated for a baby weighing 2.2 kg.
- **BCG** is given at birth for babies ≥2 kg, and routine immunization schedule should be followed without delay based on birth weight alone.
*1, 2 and 3*
- While statements 1 and 3 correctly identify beneficial practices (exclusive breastfeeding and kangaroo care), statement 2 is incorrect.
- **Vaccination guidelines** (IAP/UIP) recommend administering **BCG at birth** for babies ≥2 kg, and routine immunizations as per schedule without weight-based delays for a 2.2 kg baby.
Breastfeeding Indian Medical PG Question 9: Neo-natal infection in a Hepatitis 'B' positive pregnant woman can be prevented by administering:
- A. Hepatitis 'B' vaccine
- B. Immunoglobulin
- C. Vaccine and Immunoglobulin (Correct Answer)
- D. Corticosteroids
Breastfeeding Explanation: ***Vaccine and Immunoglobulin***
- Administering both the **Hepatitis B vaccine** and **Hepatitis B immune globulin (HBIG)** provides both active and passive immunity to the newborn.
- This combination is crucial for preventing perinatal transmission of HBV from an infected mother, significantly reducing the risk of the baby becoming a chronic carrier.
*Hepatitis 'B' vaccine*
- The vaccine alone provides **active immunity**, which takes time to develop, thus not offering immediate protection against acute exposure at birth.
- While essential for long-term protection, it's insufficient as a sole measure for newborns at high risk of immediate infection.
*Immunoglobulin*
- **Hepatitis B immune globulin (HBIG)** provides **passive immunity**, offering immediate but short-term protection.
- It contains pre-formed antibodies that neutralize the virus, but it does not confer lasting immunity.
*Corticosteroids*
- **Corticosteroids** are used as anti-inflammatory or immunosuppressive agents and have no role in preventing viral infections like Hepatitis B.
- Their use in this context would be inappropriate and could even be harmful.
Breastfeeding Indian Medical PG Question 10: Which of the following are neonatal complications of maternal diabetes during pregnancy?
I. Hyperbilirubinemia
II. Hypocalcemia
III. Cardiomyopathy
IV. Hypoglycemia
Select the correct answer using the code given below :
- A. I, II and III
- B. I, II and IV (Correct Answer)
- C. II, III and IV
- D. I, III and IV
Breastfeeding Explanation: ***I, II and IV***
- This correctly identifies the three **most common and clinically significant neonatal complications** of maternal diabetes: **hyperbilirubinemia**, **hypocalcemia**, and **hypoglycemia**.
- **Hypoglycemia** is the **most frequent complication** (25-50% of infants), occurring due to fetal hyperinsulinemia that persists after birth when maternal glucose supply is cut off.
- **Hypocalcemia** occurs in 20-50% of cases due to impaired parathyroid hormone response, hypomagnesemia, and altered calcium-phosphorus metabolism.
- **Hyperbilirubinemia** results from polycythemia (due to chronic intrauterine hypoxia), increased RBC breakdown, and impaired hepatic conjugation.
*I, II and III*
- While this includes **hyperbilirubinemia**, **hypocalcemia**, and **cardiomyopathy**, it inappropriately excludes **hypoglycemia**, which is the **most common and most critical** neonatal complication requiring immediate monitoring and management.
- Omitting hypoglycemia makes this option medically incorrect as a primary answer.
*II, III and IV*
- This option excludes **hyperbilirubinemia**, which is a very common finding (occurs in up to 25% of infants of diabetic mothers) due to increased erythropoiesis and RBC destruction.
- Fetal hyperinsulinemia drives increased oxygen consumption, leading to relative hypoxia and compensatory polycythemia.
*I, III and IV*
- This option misses **hypocalcemia**, which is one of the **classic metabolic complications** seen in 20-50% of infants of diabetic mothers.
- Hypocalcemia typically presents in the first 24-72 hours of life and is exacerbated by concurrent **magnesium deficiency**, which impairs PTH secretion and action.
**Note:** All four listed complications (I, II, III, and IV) are recognized complications of maternal diabetes. Hypertrophic cardiomyopathy occurs in 10-20% of cases but is generally less common than the metabolic triad of hypoglycemia, hypocalcemia, and hyperbilirubinemia, which require routine screening in all infants of diabetic mothers.
