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 ["0.2"]
Explanation
Step 1: Determine the concentration of morphine sulfate available. = 10 mg/mL
Step 2: Determine the dose of morphine sulfate to be administered. = 2 mg
Step 3: Calculate the volume to be administered using the formula: Volume to be administered = Dose ÷ Concentration
Step 4: Perform the division. Calculation: 2 mg ÷ 10 mg/mL = 0.2 mL
Step 5: Round the answer to the nearest tenth if necessary. = 0.2 mL (no rounding needed)
The nurse should administer 0.2 mL per dose.
Correct Answer is A
Explanation
Choice A reason:
The first step in removing an NG tube is to verify the provider’s prescription to discontinue the tube. This ensures that the removal is authorized and appropriate for the client’s current condition.
Choice B reason:
Disconnecting the tube from the wall suction is an important step, but it should be done after verifying the provider’s prescription. This step prevents any suction-related complications during the removal process.
Choice C reason:
Performing hand hygiene is crucial to prevent infection, but it is not the first step. Hand hygiene should be performed after verifying the provider’s prescription and before touching the client or any equipment.
Choice D reason:
Providing mouth care to the client is important for comfort and hygiene, but it is not the first step in the process of removing an NG tube. This can be done after the tube has been safely removed.
