Which of the following is a prototype progeria sndrome ?
- A.
Hutchinson–Gilford syndrome
- B.
Werner's syndrome
- C.
Cockayne's syndrome
- D.
Xeroderma pigmentosum
Correct Answer
A. Hutchinson–Gilford syndromeExplanation
Hutchinson-Gilford syndrome is a prototype progeria syndrome characterized by premature aging and rapid decline in health. It is a rare genetic disorder that affects children, causing them to age rapidly, leading to various health complications and a shortened lifespan. This syndrome is caused by a mutation in the LMNA gene, which is responsible for producing a protein that helps maintain the structure of the nucleus in cells. The premature aging symptoms include hair loss, wrinkled skin, joint stiffness, cardiovascular problems, and a higher risk of developing cancer. Werner's syndrome, Cockayne's syndrome, and Xeroderma pigmentosum are also genetic disorders but are not considered prototype progeria syndromes.Rate this question:

Which of the following is known as adult progeria ?
- A.
Hutchinson–Gilford syndrome
- B.
Werner's syndrome
- C.
Cockayne's syndrome
- D.
Xeroderma pigmentosum
Correct Answer
B. Werner's syndromeExplanation
Werner's syndrome is known as adult progeria because it is a rare genetic disorder that causes premature aging in individuals. It typically begins in adolescence or early adulthood and is characterized by the appearance of aging-related symptoms such as gray hair, wrinkled skin, and age-related diseases like cataracts and heart disease. This condition is caused by mutations in the WRN gene, which is involved in DNA repair and maintenance. Unlike other progeria syndromes, Werner's syndrome does not affect intellectual development.Rate this question:

Autosomal recessive inheritance is seen in all of the following except
- A.
Carpenter syndrome
- B.
Nail–patella syndrome
- C.
Laurence–Moon syndrome
- D.
Cockayne syndrome
Correct Answer
B. Nail–patella syndromeExplanation
Autosomal recessive inheritance means that both copies of a gene must be mutated in order for a person to develop the associated condition. In Nail-patella syndrome, the inheritance pattern is autosomal dominant, not recessive. This means that only one copy of the mutated gene is needed for the condition to be present. Therefore, Nail-patella syndrome does not fit the criteria for autosomal recessive inheritance.Rate this question:

CHEOPS pain scale for infants does not include
- A.
Cry
- B.
Facial
- C.
Torso
- D.
Oxygen saturation
Correct Answer
D. Oxygen saturationExplanation
The CHEOPS pain scale for infants is a tool used to assess pain in young children. It consists of various behavioral and physiological indicators of pain. The scale includes crying, facial expressions, and torso movements as observable signs of pain. However, it does not include oxygen saturation as a parameter for pain assessment. Oxygen saturation is a measure of the amount of oxygen in the blood and is not directly related to pain perception. Therefore, it is not included in the CHEOPS pain scale.Rate this question:

Treatment of nocturnal enuresis with least chance of relapse is
- A.
Imipramine
- B.
Bed alarm
- C.
Oxybutynin
- D.
Desmopressin
Correct Answer
B. Bed alarmExplanation
A bed alarm is the most effective treatment for nocturnal enuresis with the least chance of relapse. This device consists of a sensor that detects moisture and triggers an alarm, waking the individual when they start to wet the bed. By waking the person up, the bed alarm helps to condition their brain to recognize the need to wake up and use the bathroom during the night. This behavioral intervention is highly effective in treating bedwetting and has a lower chance of relapse compared to other treatments like medication (Imipramine, Oxybutynin, Desmopressin) which may have side effects or require continued use.Rate this question:

Prodormal stage of measles is NOT infectious
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement that the prodromal stage of measles is not infectious is false. The prodromal stage is the initial stage of the disease where symptoms such as fever, cough, runny nose, and red eyes appear. During this stage, the infected person is highly contagious and can easily spread the virus to others through respiratory droplets. It is important to take precautions and isolate individuals in the prodromal stage to prevent the spread of measles.Rate this question:

Lymph node biopsy is diagnostic in kawasaki disease.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Lymph node biopsy is not a diagnostic test for Kawasaki disease. The diagnosis of Kawasaki disease is usually based on clinical criteria, such as the presence of fever, rash, conjunctivitis, changes in the lips and mouth, swollen hands and feet, and other characteristic symptoms. Laboratory tests, such as blood tests and echocardiograms, are also used to support the diagnosis. Lymph node biopsy may be performed in some cases to help rule out other possible causes of the symptoms, but it is not considered a definitive diagnostic test for Kawasaki disease.Rate this question:

Prebiotics are used in management of Necrotising enterocolitis.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Prebiotics are indeed used in the management of Necrotising enterocolitis (NEC). NEC is a serious gastrointestinal disease that primarily affects premature infants. Prebiotics, such as human milk oligosaccharides (HMOs), help promote the growth of beneficial gut bacteria and improve gut health. They have been shown to reduce the risk and severity of NEC in preterm infants. Therefore, the statement "Prebiotics are used in management of Necrotising enterocolitis" is true.Rate this question:

Posterior iliac horns are seen in
- A.
Crouzan Syndrome
- B.
Nail Patella Syndrome
- C.
Pierre Robbins Syndrome
- D.
Fishers Syndrome
Correct Answer
B. Nail Patella SyndromeExplanation
Posterior iliac horns are bony projections that can be seen on the posterior aspect of the ilium bone in the pelvis. These horns are a characteristic feature of Nail Patella Syndrome, also known as hereditary osteo-onychodysplasia. Nail Patella Syndrome is a genetic disorder that affects the development of nails, kneecaps, and other skeletal structures. The presence of posterior iliac horns is a diagnostic feature of this syndrome, along with other symptoms such as abnormal nails, absent or underdeveloped kneecaps, and skeletal abnormalities.Rate this question:

Brachycephaly is due to premature fusion of
- A.
Coronal Sutures
- B.
Lambdoid Sutures
- C.
Sagittal Sutures
- D.
Parietal Sutures
Correct Answer
A. Coronal SuturesExplanation
Brachycephaly is a condition characterized by a short and wide head shape. It is caused by the premature fusion of the coronal sutures, which are the fibrous joints that connect the frontal and parietal bones of the skull. When these sutures fuse too early, it restricts the growth of the skull in the front to back direction, resulting in a flattened and wider head shape. The premature fusion of other sutures mentioned in the options, such as the lambdoid, sagittal, or parietal sutures, do not lead to brachycephaly.Rate this question:

Neonatal Reflex which never reappears in later life is
- A.
Moros
- B.
Glabellar
- C.
Snout
- D.
Grasp
Correct Answer
A. MorosExplanation
The Moro reflex is a neonatal reflex that occurs when a baby is startled by a sudden movement or noise. The reflex is characterized by the baby extending their arms and legs outwards and then bringing them back in towards their body. This reflex is present in newborns but typically disappears within the first few months of life. The Glabellar, Snout, and Grasp reflexes are also present in newborns but may reappear in certain neurological conditions or as a result of brain damage.Rate this question:

Bag & Mask ventillation is contraindicated in
- A.
Cleft Lip
- B.
Diaphragmatic Hernia
- C.
Meconium Aspiration
- D.
None
Correct Answer
B. Diaphragmatic HerniaExplanation
Bag and mask ventilation is contraindicated in diaphragmatic hernia because it can worsen the condition. Diaphragmatic hernia is a defect in the diaphragm that allows abdominal organs to move into the chest cavity, compressing the lungs and limiting their ability to expand. Bag and mask ventilation can increase the pressure in the chest, further compressing the lungs and potentially causing more harm. Therefore, alternative methods of ventilation should be used in cases of diaphragmatic hernia.Rate this question:
