What is the most significant risk factor for clubfoot?
Smoking
Trauma during pregnancy
Hypertension
Decreased circulation
The Correct Answer is A
Choice A reason:
Smoking is the most significant risk factor for clubfoot, according to several studies that have found a strong association between maternal smoking during pregnancy and the occurrence of clubfoot in the offspring. Smoking may affect the development of the muscles and tendons in the fetus, leading to abnormal positioning of the foot.
Choice B reason:
Trauma during pregnancy is not a significant risk factor for clubfoot, as there is no evidence that physical injury to the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.
Choice C reason:
Hypertension is not a significant risk factor for clubfoot, as there is no evidence that high blood pressure in the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.
Choice D reason:
Decreased circulation is not a significant risk factor for clubfoot, as there is no evidence that poor blood flow to the mother or the fetus can cause this deformity. Clubfoot is a congenital condition that is present at birth and usually detected by prenatal ultrasound.

Correct Answer is A
Explanation
Choice A reason:
This is a normal WBC for a newborn. According to MedlinePlus, the normal amount of white blood cells (WBCs) found in the bloodstream of a newborn infant is between 4,500 and 10,000 per microliter of blood. The reference ranges for WBC count established by Mayo Medical Laboratories for infants from birth to 2 years are as follows:.
• Birth: 9.0 to 30.0 x 10 9 /L.
• 1 to 7 days: 9.4 to 34.0 x 10 9 /L.
• 8 to 14 days: 5.0 to 21.0 x 10 9 /L.
• 15 days to 1 month: 5.0 to 20.0 x 10 9 /L.
• 2 to 5 months: 5.0 to 15.0 x 10 9 /L. Therefore, a newborn's WBC of 15,000 is within the normal range and does not indicate any problem.
Choice B reason:
You must call the doctor. This is not a correct answer because there is no need to call the doctor for a normal WBC in a newborn. Calling the doctor unnecessarily may cause anxiety and a waste of time and resources.
Choice C reason:
This indicates a severe infection. This is not a correct answer because a WBC of 15,000 does not necessarily indicate a severe infection in a newborn. A high WBC, also called leukocytosis, may be related to infection, but it can also be caused by other factors such as stress, inflammation, trauma, medication, or blood disorders. Moreover, the type and severity of infection can be better assessed by looking at the differential count of the different types of white blood cells (neutrophils, eosinophils, basophils, monocytes, and lymphocytes) and other signs and symptoms.
Choice D reason:
This is a lab error. This is not a correct answer because a WBC of 15,000 is not likely to be a lab error in a newborn. Lab errors can occur due to improper collection, handling, or analysis of blood samples, but they are rare and usually detected by quality control measures. A WBC of 15,000 is within the normal range for a newborn and does not require repeating the test unless there is a strong suspicion of an error or an inconsistency with other results or clinical findings.
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.
