A nurse is preparing a presentation at a senior center about age-related musculoskeletal changes. Which of the following changes should the nurse plan to include?
Reduced chest width
Increased force of isometric contraction
Decreased muscle mass
Thickened vertebral discs
The Correct Answer is C
Choice A reason:
Reduced chest width: Aging does not typically result in a reduced chest width. Instead, changes in posture and the curvature of the spine can make the chest appear less prominent. The primary musculoskeletal changes with aging involve bone density, muscle mass, and joint flexibility
Choice B reason:
Increased force of isometric contraction: This is incorrect. Aging is associated with a decrease in muscle strength and mass, not an increase. The force of muscle contractions generally diminishes with age due to the loss of muscle fibers and changes in muscle composition.
Choice C reason:
Decreased muscle mass: This is correct. One of the most significant age-related musculoskeletal changes is sarcopenia, which is the loss of muscle mass and strength. This process begins around the age of 30 and accelerates with age, leading to decreased physical strength and increased risk of falls and fractures.
Choice D reason:
Thickened vertebral discs: Aging typically leads to the thinning and dehydration of intervertebral discs, not thickening. This can result in a reduction in height and increased susceptibility to spinal issues such as herniated discs and spinal stenosis.

Correct Answer is B
Explanation
Choice A reason: A Negative-Pressure Isolation Room
A negative-pressure isolation room is typically used for patients with airborne infections, such as tuberculosis, to prevent the spread of infectious particles through the air. Scabies, however, is spread through direct skin-to-skin contact or contact with contaminated items, not through the air. Therefore, a negative-pressure room is not necessary for a client with scabies.
Choice B reason: A Private Room
Placing the client in a private room is the appropriate action. This helps to prevent the spread of scabies to other patients and staff. Scabies is highly contagious, and isolating the affected individual minimizes the risk of transmission. The client should remain in the private room until the treatment regimen is complete and they are no longer contagious.
Choice C reason: A Semi-Private Room with a Client Who Has Pediculosis Capitis
A semi-private room with a client who has pediculosis capitis (head lice) is not appropriate. While both conditions involve parasites, they are different and require separate management and treatment protocols. Placing two clients with different contagious conditions in the same room increases the risk of cross-contamination and complicates infection control measures.
Choice D reason: A Positive-Pressure Isolation Room
A positive-pressure isolation room is used to protect immunocompromised patients from external contaminants by ensuring that air flows out of the room rather than in. This type of room is not suitable for a client with scabies, as it does not address the mode of transmission for this condition.
Correct Answer is B
Explanation
Choice A reason:
Draw sheet: A draw sheet can be used to assist in repositioning a patient, but it is not the most effective method for turning a client who has undergone spinal fusion. The primary concern is to maintain spinal alignment, which is best achieved through the log roll technique.
Choice B reason:
Log roll: The log roll technique is the preferred method for turning patients who have had spinal surgery. This technique involves moving the patient as a single unit, keeping the spine in alignment to prevent any twisting or bending that could disrupt the surgical site. It is especially important for obese patients to ensure that the spine remains stable during movement.
Choice C reason:
Sliding board: A sliding board is typically used to assist with transfers from one surface to another, such as from a bed to a wheelchair. It is not suitable for turning a patient in bed, particularly one who has had spinal surgery.
Choice D reason:
Hoyer lift: A Hoyer lift is a mechanical device used to lift and transfer patients who are unable to move themselves. While it can be useful for transferring patients, it is not designed for turning patients in bed and does not provide the necessary support to maintain spinal alignment during a turn.
