a patient comes into the er with a broken radius. the epip ysis are out of positio
not penetrated. which of the following describes the patients condition.
displaced, open fracture
displaced, closed fracture
nondisplaced, open fracture
nondisplaced, closed fracture

Explanation:

• For the first question: The parathyroid glands secrete parathyroid hormone (PTH), which increases blood calcium levels. If the parathyroid glands are removed, PTH is no longer secreted. Without PTH, mechanisms that increase blood calcium (such as bone resorption, increased renal calcium re - absorption, and increased intestinal calcium absorption) are not activated. So, calcium levels will decrease.
• For the second question: A displaced fracture means the bone fragments are out of their normal alignment (the epiphysis are out of position). A closed fracture is one where the skin is not penetrated. An open fracture has a break in the skin. Since the skin is not penetrated in this case, it is a closed fracture.

Answer:

• First question: A. decrease
• Second question: B. displaced, closed fracture
