Which of these is a characteristic of a preterm infant?
Hypertonia.
Long toenails.
Lanugo.
Dry skin.
The Correct Answer is C
Choice A reason:
Hypertonia is not a characteristic of a preterm infant, but rather of a post-term infant. Hypertonia means increased muscle tone or stiffness, which is more common in infants who are overdue. Preterm infants have poor muscle tone and less subcutaneous fat.
Choice B reason:
Long toenails are also not a characteristic of a preterm infant but of a post-term infant. Long toenails indicate that the infant has grown beyond the expected gestational age. Preterm infants have short and brittle nails.
Choice C reason:
Lanugo is a characteristic of a preterm infant. Lanugo is fine, downy hair that covers the body of the fetus. It usually disappears by the 36th week of gestation, but preterm infants may still have it at birth.
Choice D reason:
Dry skin is not a characteristic of a preterm infant but of a post-term infant. Dry skin indicates that the infant has lost moisture and subcutaneous fat due to prolonged exposure to the amniotic fluid. Preterm infants have thin and transparent skin that may be covered by vernix caseosa, a white, cheesy substance that protects the skin from the amniotic fluid.

Correct Answer is B
Explanation
Choice A reason:
This is incorrect because formula-fed newborns typically have one or more stools per day, not every 3 days. Stooling less frequently than once a day may indicate constipation.
Choice B reason:
This is correct because breastfed newborns usually have two to three stools per day, which are soft and yellow. Breastfed babies may also have stools less frequently, even once every 10-14 days, as long as the stool is soft.
Choice C reason:
This is incorrect because newborns should be fed formula on demand, not on a strict schedule. The average feeding interval for formula-fed newborns is about 3 to 4 hours.
Choice D reason:
This is incorrect because newborns should be breastfed eight to 12 times per day, not five to seven times. Breastfeeding more frequently helps to establish milk supply and prevent engorgement. - Stanford Medicine.
Correct Answer is ["A","B"]
Explanation
Choice A reason:
Slow growth is a common symptom of thalassemia, especially in children. It is caused by the reduced production of hemoglobin and red blood cells, which leads to anemia and poor oxygen delivery to the tissues. Slow growth can also affect the development of facial bones and cause deformities.
Choice B reason:
Fatigue is another common symptom of thalassemia, also related to anemia and low oxygen levels in the body. People with thalassemia may feel tired, weak, and short of breath even after mild physical activity. Fatigue can also affect their mood, concentration, and quality of life.
Choice C reason:
Hematoma is not a typical symptom of thalassemia. Hematoma is a collection of blood under the skin or in an organ, usually caused by trauma, injury, or bleeding disorders. People with thalassemia may have a higher risk of bleeding due to low platelet counts or frequent blood transfusions, but this does not necessarily result in hematoma.
Choice D reason:
Pruritus is not a typical symptom of thalassemia. Pruritus is a sensation of itching that can affect any part of the body. It can have many causes, such as dry skin, allergies, infections, or liver problems. People with thalassemia may experience pruritus as a side effect of iron overload or iron chelation therapy, but it is not a direct consequence of the condition.
Choice E reason:
Ecchymoses are not typical symptoms of thalassemia. Ecchymoses are large bruises that appear on the skin due to bleeding under the surface. They can be caused by trauma, injury, or bleeding disorders. People with thalassemia may have a higher risk of bleeding due to low platelet counts or frequent blood transfusions, but this does not necessarily result in ecchymoses.
