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

Answer and Explanation

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.

A. Place a black tag on the client’s upper body and attempt to help the next client in need. B. Reposition the client’s upper airway a second time before assessing his respirations. C. Start CPR. D. Place a red tag on the client’s upper body and obtain immediate help from other personnel.

Correct Answer is A

Explanation

Choice A reason:

Place a black tag on the client’s upper body and attempt to help the next client in need: In mass casualty incidents, triage is used to prioritize treatment based on the severity of injuries and the likelihood of survival. A black tag indicates that the victim is deceased or has injuries that are not compatible with life and that resources should be directed to those who have a better chance of survival. Since the client remains apneic even after repositioning the airway, it indicates that they are not breathing and have a very low chance of survival.

Choice B reason:

Reposition the client’s upper airway a second time before assessing his respirations: While ensuring the airway is open is crucial, if the client remains apneic after the initial repositioning, further attempts are unlikely to be successful in a mass casualty scenario where time and resources are limited2. The priority is to move on to other victims who may have a higher chance of survival.

Choice C reason:

Start CPR: In a mass casualty situation, CPR is typically not initiated for victims who are apneic and pulseless due to the need to allocate resources to those who have a higher likelihood of survival3. The focus is on providing immediate care to those who can benefit the most from it.

Choice D reason:

Place a red tag on the client’s upper body and obtain immediate help from other personnel: A red tag is used for victims who require immediate life-saving interventions and have a high chance of survival if treated promptly4. Since the client is apneic and remains so after airway repositioning, they do not meet the criteria for a red tag.
