In evaluating a newborn’s gestational age, which of the following findings is generally associated with a significantly advanced gestational age?
सही उत्तर: घ) D) Measurement of Head Circumference >35 cm
Option D is correct. A head circumference exceeding 35 cm (approximately 14 inches) typically indicates a gestational age greater than 37 weeks, indicating the fetus has reached a more advanced stage of development and growth.

A 6-month-old infant presents with bilateral edema, hematuria, and hypertension. Laboratory tests reveal elevated serum creatinine and proteinuria. Which of the following conditions is MOST likely?
सही उत्तर: ख) B) Post-Streptococcal Glomerulonephritis
Option B is correct. The presentation – edema, hematuria, hypertension, and proteinuria – strongly suggests post-streptococcal glomerulonephritis, a common autoimmune condition often following a streptococcal infection. While other options could present similarly, the combination points to this specific diagnosis.

What is the primary physiological effect of magnesium sulfate administered during labor that contributes to its potential toxicity?
सही उत्तर: ग) C) Direct blockade of neuromuscular transmission and decreased myotonia
Option C is correct. Magnesium sulfate’s primary mechanism in labor involves blocking voltage-gated calcium channels, reducing muscle excitability (including uterine muscles), and consequently decreasing contractions. The other options represent potential but less direct effects or actions of magnesium.

A 32-year-old pregnant woman in her third trimester presents with painless, recurrent, bright red vaginal bleeding. The ultrasound reveals a gestational sac without fetal cardiac activity. What is the MOST likely diagnosis? (a) Placenta Previa (b) Complete Gestational Trophoblastic Abortion (c) Uterine Subinvolution (d) Cervical Cryptococcosis
सही उत्तर: ख) Complete Gestational Trophoblastic Abortion
(b) is correct. Painless, recurrent bright red vaginal bleeding with absent fetal heart sounds suggests complete gestational trophoblastic abortion (gestational choriocarcinoma). (a) presents with abdominal pain, (c) is associated with delayed uterine contractions and (d) causes symptoms related to a fungal infection in the central nervous system.

A 10-year-old boy is brought to the clinic complaining of fatigue, bone pain, and recurrent fractures. Laboratory tests reveal a markedly low serum calcium level and elevated parathyroid hormone levels. What is the MOST likely diagnosis? (a) Rickets (b) Osteomalacia (c) Paget’s Disease of Bone (d) Hyperparathyroidism
सही उत्तर: घ) Hyperparathyroidism
(d) is correct. The combination of fatigue, bone pain, recurrent fractures and high parathyroid hormone levels are strongly indicative of primary hyperparathyroidism, which leads to excessive calcium release into the bloodstream. (a) and (b) are linked to vitamin D deficiency, while (c) causes generalized bone abnormalities without such specific parathyroid hormone elevation.

A newborn infant is admitted to the neonatal unit exhibiting lethargy, poor feeding, and jaundice. Blood tests reveal a low level of conjugated bilirubin. The pediatrician suspects severe early-onset neonatal hyperbilirubinemia. Which of the following interventions would be MOST appropriate? (a) Phototherapy with blue light. (b) Exchange transfusion. (c) Administration of intravenous immunoglobulin (IVIG). (d) Oral iron supplementation.
सही उत्तर: क) Phototherapy with blue light
(a) is correct. Severe early-onset neonatal hyperbilirubinemia usually responds effectively to phototherapy, which utilizes blue light to convert bilirubin into a form that can be excreted in the urine. (b) and (c) are reserved for more severe cases, while (d) has no role in treating jaundice.

A 28-year-old female presents with sudden onset of severe lower abdominal pain, nausea, and vomiting. Upon examination, she has a positive Sims' sign. A urinalysis reveals proteinuria and hematuria. Which of the following conditions is MOST likely? (a) Ovarian Cyst Rupture (b) Ectopic Pregnancy (c) Acute Appendicitis (d) Urinary Tract Infection (UTI)
सही उत्तर: ख) Ectopic Pregnancy
(b) is correct. The sudden onset of severe lower abdominal pain, positive Sims' sign, proteinuria and hematuria strongly suggests ectopic pregnancy. (a) typically has more localized pain, (c) presents with right iliac fossa pain and (d) would not usually cause such marked urinary findings.

A pediatrician is evaluating a 6-month-old infant presenting with fever, irritability, and poor feeding. Physical examination reveals enlarged cervical lymph nodes and a maculopapular rash that started on the face and spread downwards. Based on these findings, which of the following viral infections is MOST likely? (a) Rubella Virus (b) Cytomegalovirus (CMV) (c) Varicella-Zoster Virus (Chickenpox) (d) Adenovirus
सही उत्तर: क) Rubella Virus
(a) is correct. The symptoms – fever, enlarged lymph nodes, and a maculopapular rash spreading downwards - are highly characteristic of Rubella virus infection (German measles). (b) presents with more severe manifestations, typically including hepatosplenomegaly, while varicella presents as vesicular lesions and adenovirus causes respiratory illness primarily.

A pregnant woman at 36 weeks gestation presents with sudden onset hypertension and proteinuria. Laboratory investigations reveal elevated creatinine levels. Based on these findings, which of the following diagnoses is MOST likely?
सही उत्तर: ग) Eclampsia
The combination of new-onset hypertension and proteinuria with end-organ dysfunction (indicated by elevated creatinine) strongly suggests pre-eclampsia. Eclampsia develops if seizures occur, HELLP syndrome has further specific blood abnormalities, and gestational diabetes is characterized by hyperglycemia.

A 28-year-old primigravida reports experiencing fetal movement for the first time at 24 weeks of gestation. What is the MOST common reason for this delayed perception?
सही उत्तर: घ) Autonomic Nervous System Delay
The limited pelvic diameter, particularly in primiparous women, often delays the first perception of fetal movements (quickening) until approximately 28-30 weeks. The other options can contribute to discomfort but don't explain the delayed onset.
