D: Maintain dairy sources of calcium intake. Relying solely on dairy sources neglects the diverse calcium needs across different ages, limiting the effectiveness of dietary advice and strategies for adequate intake.
Question 23
Regular
A nurse is caring for a client with an undiagnosed bone disease. When instructing on the normal process to maintain bone tissue, which process transforms osteoblasts into mature bone cells?
Correct!
Incorrect
The correct answer is: C
Rationale
Ossification and calcification are the processes that transform osteoblasts into mature bone cells, allowing the formation of a stable and mineralized bone matrix essential for proper bone structure and function.
A: Remodelling Involves the continuous renewal of bone tissue through the action of osteoclasts and osteoblasts but does not specifically transform osteoblasts into mature bone cells.
B: Resorption Refers to the process where bone tissue is broken down, allowing minerals to be released into the bloodstream, not the maturation of osteoblasts into bone cells.
D: Epiphyses and diaphysis formation pertains to the structural development of long bones and does not directly address the transformation of osteoblasts into mature bone cells.

Question 24
Multiple Choice
A client is scheduled to have an x-ray examination of the shoulder in which the synovial fluid will be aspirated and sent to the laboratory for analysis. This will be followed by administration of a contrast medium and x-rays. The nurse understands that the client will be undergoing which test(s)?
Correct!
Incorrect
The correct answer is: B,C
Rationale
The client will be undergoing arthrocentesis and arthrogram.
Arthrocentesis involves aspirating synovial fluid for laboratory analysis, making it essential prior to administering a contrast medium for the subsequent arthrogram x-ray. This combination allows for comprehensive evaluation of joint conditions.
A: Arthroscopy involves direct visualization of the joint through an incision, not fluid aspiration or contrast medium injections.
D: Bone densitometry measures bone density, unrelated to joint fluid analysis or x-ray contrast procedures.
E: Electromyography assesses muscle and nerve function, offering no connection to the processes of fluid aspiration or joint imaging.

Question 25
Multiple Choice
The client who is about to undergo arthroscopy of the knee begins to describe the procedure to the nurse. What statement(s) indicate to the nurse that the client understands the procedure?
Correct!
Incorrect
The correct answer is: B,C,D
Rationale
The client indicates understanding of the procedure with statements about a needle being inserted, potential imaging for verification, and laboratory analysis of joint fluid.
B: A needle will be inserted into the joint space. This demonstrates comprehension of the procedure's invasive nature, which involves accessing the knee joint for diagnostic or therapeutic purposes.
C: A special scan may be done to verify the placement of the needle. This reflects awareness of the importance of accurate needle placement during arthroscopy to ensure safety and efficacy.
D: Fluid is taken from the joint for laboratory analysis. This highlights the client's knowledge of the procedure's potential outcomes, including the investigation of joint fluid to aid in diagnosis.
A: This procedure does not require an anesthetic. Understanding that anesthesia is typically necessary for arthroscopy indicates a lack of awareness regarding pain management protocols during the procedure.
E: It is normal to hear crackling or clicking noises in the joint for about a week after the procedure. Misunderstanding the expected post-operative symptoms suggests limited knowledge regarding the recovery process following arthroscopic surgery.
