Care of the Normal Newborn Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Care of the Normal Newborn. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Care of the Normal Newborn Indian Medical PG Question 1: A 3-4 month old baby with heart rate 250/min, QRS complex less than 0.07 sec and no P wave, Diagnosis will be :
- A. VT
- B. PSVT with block
- C. SVT (Correct Answer)
- D. Sinus tachycardia
Care of the Normal Newborn Explanation: **SVT**
- A heart rate of 250/min in a 3-4 month old infant, along with a **narrow QRS complex (<0.07 sec)**, is highly indicative of **supraventricular tachycardia (SVT)**.
- The **absence of visible P waves** suggests that the atrial activity is either too rapid to be clearly distinguished or is retrograde and hidden within the QRS complex.
*VT*
- **Ventricular tachycardia (VT)** is characterized by **wide QRS complexes** (typically >0.09-0.10 sec in adults, proportionally less in infants) because the impulse originates in the ventricles.
- The patient's QRS complex is **narrow (<0.07 sec)**, ruling out typical VT.
*PSVT with block*
- **Paroxysmal supraventricular tachycardia (PSVT) with block** would still present with a rapid atrial rate, and while there might be block to the ventricles, the dominant rhythm would stem from supraventricular activity causing narrow QRS, but the term "with block" usually implies some degree of AV nodal block which would lead to a ventricular rate slower than the atrial rate, unlike the observed 250/min.
- The absence of P waves makes identification of a specific "block" pattern difficult, and the high ventricular rate favors a direct conduction rather than a blocked rhythm limiting ventricular response.
*Sinus tachycardia*
- **Sinus tachycardia** is usually characterized by discernible **P waves** preceding each QRS complex and a heart rate that typically doesn't exceed 220 bpm in infants unless under extreme physiological stress.
- A heart rate of 250/min is generally above the physiological limit for sinus tachycardia in infants, and the **absence of P waves** further distinguishes it from sinus tachycardia.
Care of the Normal Newborn Indian Medical PG Question 2: According to neonatal resuscitation protocol, how much oxygen to give in a term neonate with apnea and bradycardia initially?
- A. 100%
- B. 21% (Correct Answer)
- C. 50%
- D. 30%
Care of the Normal Newborn Explanation: ***21%***
- According to **NRP (Neonatal Resuscitation Program) 2020 guidelines**, for **term neonates (≥35 weeks gestation)** requiring resuscitation, the initial recommendation is to use **room air (21% oxygen)** to minimize the risk of hyperoxia and oxidative injury.
- Multiple randomized controlled trials have demonstrated that room air is as effective as 100% oxygen for initial resuscitation.
- Supplemental oxygen is only added if **oxygen saturation targets** are not met despite adequate ventilation, and should be titrated using **pulse oximetry**.
*30%*
- This concentration is **higher than room air** and is not the initial recommendation for term neonates needing resuscitation.
- Starting with a higher oxygen concentration can lead to **oxidative stress** without immediate benefit.
- Higher initial concentrations (21-30%) are reserved for **preterm neonates (<35 weeks)**.
*100%*
- Administering **100% oxygen** can be harmful to a neonate, potentially causing **oxidative injury** to developing organs, including the lungs, brain, and retina.
- This was the old practice but has been **discontinued** based on evidence showing increased mortality and morbidity.
- High concentrations are no longer recommended even in severe cases; oxygen should be titrated to saturation targets.
*50%*
- While lower than 100%, 50% oxygen is still **not the initial recommended concentration** for term neonates in resuscitation protocols.
- The goal is to start with **21% oxygen** and gradually increase based on **pulse oximetry monitoring** and target saturation ranges if 21% is insufficient.
Care of the Normal Newborn Indian Medical PG Question 3: A term infant is born to a known HIV-positive mother. She has been taking antiretroviral medications for the weeks prior to the delivery of her infant. Routine management of the healthy infant should include which of the following?
- A. HIV ELISA on the infant to determine if congenital infection has occurred
- B. Admission to the neonatal intensive care unit for close cardiovascular monitoring
- C. Chest radiographs to evaluate for congenital Pneumocystis carinii
- D. A course of zidovudine for the infant (Correct Answer)
Care of the Normal Newborn Explanation: ***A course of zidovudine for the infant***
- This is the standard of care for newborns exposed to HIV prenatally, even if the mother received **antiretroviral therapy (ART)**.
- **Zidovudine (AZT)** prophylaxis significantly reduces the risk of **perinatal HIV transmission**.
*HIV ELISA on the infant to determine if congenital infection has occurred*
- **HIV ELISA** tests detect **maternal antibodies** passed to the infant, which can persist for up to 18 months, leading to **false positive results**.
- **HIV DNA PCR** or **RNA assays** are used to diagnose HIV infection in infants.
*Admission to the neonatal intensive care unit for close cardiovascular monitoring*
- Admission to the **NICU** is generally reserved for **premature** or **symptomatic infants**, or those with specific complications.
- A **healthy, term infant** born to an HIV-positive mother on ART does not routinely require NICU admission.
*Chest radiographs to evaluate for congenital Pneumocystis carinii*
- **Pneumocystis jirovecii pneumonia (PJP)** typically presents in HIV-infected infants between **3 to 6 months of age**, not at birth.
- Prophylaxis with **trimethoprim-sulfamethoxazole (TMP-SMX)** is initiated at 4-6 weeks of age for HIV-exposed infants.
Care of the Normal Newborn Indian Medical PG Question 4: As per the latest NRP guidelines, what is the target preductal saturation after birth at 5 minutes?
- A. 65% - 70%
- B. 75% - 85%
- C. 85% - 95%
- D. 80% - 85% (Correct Answer)
Care of the Normal Newborn Explanation: ***80% - 85%***
- The Neonatal Resuscitation Program (NRP) guidelines recommend target pulse oximetry readings for **preductal oxygen saturation** in newborns.
- At **5 minutes after birth**, the expected preductal saturation range is **80% - 85%**.
- This represents the specific target for the 5-minute mark according to current NRP guidelines.
*65% - 70%*
- This range is the target for **2 minutes after birth**, reflecting the early transition from fetal circulation.
- It is **too low** for the target saturation at 5 minutes post-delivery according to NRP.
*75% - 85%*
- This range is **too broad** and spans multiple time points (3-5 minutes).
- The lower end (75%) represents the target at **3 minutes**, while 80-85% is specifically for **5 minutes**.
- NRP guidelines specify **80-85%** as the precise target range for 5 minutes, not 75-85%.
- This option is incorrect because it does not reflect the **specific** 5-minute target.
*85% - 95%*
- This higher range is the target for **10 minutes after birth**, indicating the near-complete transition to extrauterine circulation.
- It is **too high** for the expected preductal saturation at 5 minutes according to current NRP guidelines.
Care of the Normal Newborn Indian Medical PG Question 5: Which of the following is a common benign condition characterized by white/yellow keratin-filled cysts on a newborn's skin?
- A. Mongolian spots
- B. Milia (Correct Answer)
- C. Epstein pearls
- D. Congenital melanoma
Care of the Normal Newborn Explanation: ***Milia***
- These are **tiny, white bumps** (1-2mm) that appear on a newborn's nose, chin, or cheeks
- Caused by **trapped keratin beneath the skin surface** in immature sebaceous glands
- Occur in **40-50% of newborns** and are completely benign
- Resolve spontaneously within **2-4 weeks** without treatment
*Mongolian spots*
- These are **blue-gray flat birthmarks** (not cysts) caused by dermal melanocytosis
- Most commonly found on the **lumbosacral area and buttocks**
- Very common in Asian, African, and Hispanic populations but are **pigmentary lesions**, not keratin cysts
- Not the answer as they are not characterized by white/yellow cysts
*Epstein pearls*
- These are **small whitish-yellow cysts** on the **palate** (roof of mouth), not on skin
- Found in **60-85% of newborns** and are epithelial inclusion cysts
- While very common and benign, they occur on the **oral mucosa**, not the skin surface
- Not the answer as the question specifies skin
*Congenital melanoma*
- This is an **extremely rare malignant tumor**, not a benign condition
- Represents a **serious cancer** requiring immediate treatment
- Not the answer as it is neither common nor benign
Care of the Normal Newborn Indian Medical PG Question 6: What is the true statement regarding an 'at-risk baby'?
- A. Mild malnutrition with weight slightly below expected norms.
- B. Socioeconomic risk due to high birth order (more than 3). (Correct Answer)
- C. Normal birth weight above the critical threshold of 2.5 kg.
- D. Severe malnutrition with weight significantly below expected norms.
Care of the Normal Newborn Explanation: ***Socioeconomic risk due to high birth order (more than 3).***
- An **"at-risk baby"** is defined by specific criteria that identify infants vulnerable to adverse health outcomes during the neonatal and early infantile period.
- **High birth order (>3)** is a recognized risk factor as per IAP (Indian Academy of Pediatrics) and WHO guidelines, primarily due to:
- **Maternal depletion syndrome** (depleted maternal nutritional reserves from multiple pregnancies)
- **Socioeconomic constraints** (limited resources spread across more children)
- **Reduced parental attention** and care per child
- Other criteria for "at-risk baby" include: birth weight <2.5 kg, preterm birth, birth asphyxia, congenital anomalies, and maternal risk factors.
*Severe malnutrition with weight significantly below expected norms.*
- This describes **severe acute malnutrition (SAM)** in an infant or child, which is a **nutritional disorder**, not a defining criterion of an "at-risk baby" at birth.
- While malnutrition increases morbidity risk, the term "at-risk baby" specifically refers to **perinatal and neonatal risk factors** present at or around the time of birth.
- SAM is a **consequence** that may develop later, rather than a defining characteristic of the "at-risk" classification.
*Mild malnutrition with weight slightly below expected norms.*
- **Mild malnutrition** is not a criterion for classifying a baby as "at-risk" in the standard pediatric definition.
- The "at-risk baby" classification focuses on **specific measurable risk factors** (birth weight, gestational age, birth order, etc.) rather than mild nutritional deviations.
*Normal birth weight above the critical threshold of 2.5 kg.*
- A **normal birth weight (≥2.5 kg)** is actually a **protective factor** and indicates lower risk at birth.
- This statement describes a baby who does **not meet the "at-risk" criteria** based on birth weight, though other risk factors could still be present.
- Birth weight ≥2.5 kg is one indicator of adequate intrauterine growth and lower neonatal mortality risk.
Care of the Normal Newborn Indian Medical PG Question 7: Erythematous blotchy rash is seen on the abdomen, trunk, and face of a 3-day-old child along with yellowish papules. The child appears well. What is the appropriate management?
- A. Topical steroid and antibiotic lotion
- B. Topical steroid cream
- C. Intravenous antibiotics
- D. No treatment (Correct Answer)
Care of the Normal Newborn Explanation: ***No treatment (Correct Answer)***
The described symptoms—erythematous blotchy rash with yellowish papules on the abdomen, trunk, and face in a well-appearing 3-day-old neonate—are **classic for erythema toxicum neonatorum**.
**Key Features:**
- **Benign, self-limiting rash** of unknown etiology
- Affects **50-70% of term newborns**
- Typically appears on **days 2-5** of life
- Characterized by **erythematous macules/patches** with overlying **yellowish-white papules/pustules**
- Infant appears **well and thriving**
- **Resolves spontaneously** within 1-2 weeks without treatment
- Histology shows **eosinophils** in pustules
**Management:** Reassurance to parents; no medical intervention required.
---
*Topical steroid and antibiotic lotion (Incorrect)*
This approach is inappropriate because erythema toxicum neonatorum is:
- **Not an infection** (no bacterial or fungal cause)
- **Not an inflammatory condition** requiring steroids
- Misdiagnosis and overtreatment could lead to unnecessary side effects, antibiotic resistance, and mask other conditions
---
*Topical steroid cream (Incorrect)*
Topical steroids are:
- **Unnecessary** for this benign, self-resolving condition
- **Potentially harmful** in neonates (can cause skin atrophy, increased absorption)
- Provide **no therapeutic benefit** for erythema toxicum neonatorum
---
*Intravenous antibiotics (Incorrect)*
Systemic antibiotics are:
- **Entirely unwarranted** as this is a non-infectious, benign rash
- Would represent **gross overtreatment** with significant risks
- Contribute to **antibiotic resistance**
- Carry risks of adverse reactions, disruption of normal flora, and unnecessary hospitalization
**Differentials to consider (but not present here):**
- Transient neonatal pustular melanosis (present at birth)
- Neonatal acne (appears later, at 2-4 weeks)
- Miliaria (smaller, clear vesicles)
- Infectious causes (infant appears ill, requires septic workup)
Care of the Normal Newborn Indian Medical PG Question 8: Which of the following is the most practical method for transporting a newborn while maintaining a warm temperature, especially in resource-limited settings?
- A. Kangaroo Mother Care (KMC) (Correct Answer)
- B. Transport incubator
- C. Insulated box (e.g., Thermacol box)
- D. Warm water bag
Care of the Normal Newborn Explanation: ***Kangaroo Mother Care (KMC)***
- KMC involves continuous **skin-to-skin contact** between the newborn and the caregiver, which is highly effective in maintaining the infant's temperature through direct body warmth transfer.
- It is a **low-cost**, easily accessible method, making it particularly practical and sustainable in **resource-limited settings**.
- KMC is endorsed by **WHO** as an evidence-based intervention for thermal care of low birth weight and preterm infants.
*Transport incubator*
- While effective for maintaining temperature, a transport incubator is **expensive**, requires electricity or specialized batteries, and is not readily available in many resource-limited settings.
- The use of an incubator requires **trained personnel** for operation and maintenance, making it less practical for widespread use in such environments.
*Insulated box (e.g., Thermacol box)*
- An insulated box can provide some thermal insulation, but it lacks an **active heating mechanism** and does not provide tactile stimulation or bonding benefits.
- The temperature inside can still fluctuate significantly, and it does not allow for **continuous monitoring** of the newborn, increasing the risk of overheating or hypothermia if not managed carefully.
*Warm water bag*
- A warm water bag can provide localized warmth but carries a significant risk of **burns** if the water is too hot or if the bag leaks.
- Its warming effect is also **temporary** and not evenly distributed, making it less reliable for maintaining stable body temperature during prolonged transport.
Care of the Normal Newborn Indian Medical PG Question 9: Newborns typically lose how much weight in the first week?
- A. 5-10% (Correct Answer)
- B. 1-2%
- C. 11-15%
- D. 15-20%
Care of the Normal Newborn Explanation: ***5-10%***
- **Physiologic weight loss** of 5-10% of birth weight is normal in newborns during the first week of life.
- This loss is primarily due to the **mobilization of extracellular fluid** and delayed onset of full milk production (lactogenesis).
- Most infants regain their birth weight by **10-14 days** of age.
*1-2%*
- A weight loss of only 1-2% in the first week would be **less than expected** and might suggest the infant is retaining excess fluid.
- While not necessarily pathological, it's at the **lower end of the normal range** and less typical than the 5-10% range.
*11-15%*
- A weight loss greater than **10%** is generally considered **excessive** and indicates inadequate feeding or possible dehydration.
- Weight loss of 11-15% typically requires **closer monitoring**, feeding assessment, and possible lactation support or supplementation.
*15-20%*
- A weight loss of 15-20% is significantly **above the normal physiological range** and represents a serious concern for **severe dehydration** or inadequate nutritional intake.
- This degree of weight loss would warrant **immediate medical evaluation** and intervention, including possible hospitalization.
Care of the Normal Newborn Indian Medical PG Question 10: A term baby with birth weight of 2.8 kg is born to a primigravida mother through vaginal delivery and cried immediately after birth. Which of the following statements are correct regarding his initial care after birth ?
I. The baby should be initiated on breastfeeding within one hour of birth
II. The baby should be kept in a separate area from the mother
III. The baby should be administered with 0.5 mg of vitamin K intramuscularly
IV. The baby should be thoroughly examined for congenital malformations from head to toe
Select the answer using the code given below :
- A. I and IV (Correct Answer)
- B. II and III
- C. I and II
- D. I and III
Care of the Normal Newborn Explanation: ***I and IV***
- **Early initiation of breastfeeding within one hour** is crucial for promoting bonding, establishing successful lactation, and providing the newborn with colostrum for immunity.
- A comprehensive **head-to-toe examination for congenital malformations** is a standard part of immediate newborn care to identify any anomalies requiring further evaluation or intervention.
*II and III*
- **Keeping the baby with the mother (rooming-in)** is recommended to promote bonding, facilitate unrestricted breastfeeding, and enable continuous monitoring by the mother.
- The standard dose of **vitamin K administered intramuscularly for a term baby is 1 mg**, not 0.5 mg, to prevent hemorrhagic disease of the newborn.
*I and II*
- While early breastfeeding (I) is correct, **keeping the baby in a separate area from the mother (II) is incorrect** as rooming-in is highly encouraged for newborn care.
- Separating the baby can hinder initial bonding and interfere with an early and successful breastfeeding experience.
*I and III*
- **Early initiation of breastfeeding within one hour (I) is correct**, but the **dose of vitamin K (III) is incorrect**, as 1 mg is the standard, not 0.5 mg.
- Incorrect medication dosages can have clinical implications, making this combination an unsuitable choice for correct initial care.
