Question 64

A teenager wants to be given growth hormone to increase his height. The doctor took an x ray of his wrist to determine if treatment could be started. Explain what the doctor was looking for

Answer 64

The doctor was looking for the growth plates in his bone to see if he was still growing. If he had them the hormones could help him grow.

Question 65

How is the difference in the role in reproduction reflected in the difference between the male and female skeleton?

Answer 65

In the female skeleton, the pelvis is shorter and wider for child birth. In a male, the pelvis is taller and thinner.

Question 66

Dr. Haney, an orthopedic surgeon, called the admissions office of a hospital and advised that he would be admitting a patient with an epiphyseal fracture. Without any other information, the patient was assigned to the pediatric floor. What prompted this assignment?

Answer 66

The patient would go to the pediatric floor because the growth plates are still visible (which is what he fractured)

Question 67

Growth hormone can be given to people to increase their height. this requires rapid bone growth. If a young adult wants to be given growth hormone, x ray films will be taken of his or her skeleton. What is the physician looking for and how would it affect the decision to give or withhold growth hormone?

Answer 67

A physician would be looking for epiphyseal plates to determine if the person was still growing. If the person had them, they could receive the growth hormone. If they didn't have them, the growth hormone wouldn't help.
