Chapter 60 : Introduction to the Musculoskeletal System Questions
Question 1 of 5
An instructor is describing the process of bone development. What would the instructor describe as being responsible for the process of ossification?
Correct Answer: A
Rationale: Osteoblasts secrete bone matrix (mostly collagen), in which inorganic minerals, such as calcium salts, are deposited. This process of ossification and calcification transforms the blast cells into mature bone cells, called osteocytes, which are involved in maintaining bone tissue. Cortical bone is dense hard bone found in the long shafts; cancellous bone is spongy bone found in the irregular rounded edges of bone.
Question 2 of 5
A nurse is preparing a presentation for a health class about ways to ensure bone health, including the need for an adequate calcium intake. The participants are high school-aged girls. The nurse would encourage them to consume adequate calcium to maximize peak bone mass by which age?
Correct Answer: B
Rationale: Peak bone mass is attained sometime around 30 years of age. An adequate calcium intake before that time helps to maximize peak bone mass. This would result in denser bones that would be less susceptible to fracture. Bone mass begins to decrease after age 30.
Question 3 of 5
The orthopedic nurse is caring for a client diagnosed with a fracture of the radius. In which type of bone tissue does the nurse anticipate the fracture being?
Correct Answer: C
Rationale: Cancellous bone or spongy bone is light and contains many spaces making it a less solid bone than the cortical or compact bone. Collagen and cartilage are not types of bone tissue.
Question 4 of 5
The emergency department nurse is reporting the location of a fracture to the client's primary care physician. When stating the location of the fracture on the long shaft of the femur, the nurse would be most correct to state which terminology locating the fractured site?
Correct Answer: A
Rationale: A fracture that is on the diaphysis is understood to be chiefly found in the long shafts of the arms and legs. The epiphysis are rounded, irregular ends of the bones. Saying a fracture is ventially located does not assist in providing adequate details of the location of the fracture. A tuberosity is a projection from the bone or a protuberance.
Question 5 of 5
The nurse is providing client education on growth and development throughout the lifespan. When stating periods of most rapid bone growth, which period is the nurse most correct to state?
Correct Answer: C
Rationale: The period of most rapid bone growth is in the period of birth through puberty. Cell division occurs in the period of conception. Growth and organ development occurs prenatally. Throughout adulthood, growth is limited and may decrease. Instruction on the foundation of bone health such as with adequate sources of calcium and vitamin D are essential.
