Question 1

How many cervical vertebrae are there?

Accepted Answer

7

Answer

The human vertebral column is divided into several regions, and the cervical spine, located in the neck, consists of seven vertebrae. These are designated C1 through C7 and are responsible for supporting the head and allowing for a wide range of neck movements.

Question 2

A patient with bilateral femur fractures would have which of the following?

Accepted Answer

Fractures of both femurs

Answer

The term "bilateral" in medical terminology means affecting both sides of the body. The "femur" is the anatomical name for the thigh bone. Therefore, bilateral femur fractures precisely describe fractures occurring in both the left and right femur bones, indicating injuries to both thighs.

Question 3

You are called to a farmhouse on a sunny spring afternoon.  Upon arrival, a frantic mother tell you that her 4-year-old daughter was playing in the yard, stung repeatedly by several bees.  The patient is alert, screaming and crying, and can follow her mother’s commands.  Her arms and legs are swollen and show the marks of several stings.  Her body is covered in hives.  Her vital signs are blood pressure 90/40, pulse 110, respiratory rate 24, and oxygen saturation 99 percent.  Her lungs sounds are clear and equal bilaterally.  You decide to administer oxygen.  What is the best method?

Accepted Answer

Administer oxygen by blow-by.

Answer

For a 4-year-old child who is alert, screaming, and crying, administering oxygen via a mask or nasal cannula can be distressing and difficult to maintain. Blow-by oxygen allows for effective oxygen delivery without direct contact with the face, making it less frightening and more tolerable for a young patient. This method ensures the child receives supplemental oxygen while minimizing anxiety and resistance.

Question 4

What is the temporary organ of pregnancy, which functions to supply the developing fetus with oxygen and nutrients?

Accepted Answer

Uterus

Answer

The uterus is the primary muscular organ that houses and supports the entire pregnancy, providing the essential environment for fetal development. While the placenta directly facilitates nutrient and oxygen exchange, the uterus is the central structure within which this entire system operates, ensuring the fetus receives all necessary provisions for growth.

Question 5

You are on the scene of a tanker truck versus passenger vehicle collision on a rural highway.  The vehicles are just beyond a curve in the roadway and there is a distinct odor of diesel fuel.  It is dark and there is little traffic.  Which of the following should be used to alert oncoming traffic to the situation?

Accepted Answer

Reflective triangles

Answer

Reflective triangles are the safest and most appropriate warning device in this scenario, especially with the presence of diesel fuel. Unlike flares, they do not produce heat or sparks, eliminating the risk of igniting flammable materials. Their reflective properties ensure visibility to oncoming traffic in the dark, effectively alerting drivers to the hazard without creating additional dangers.
