When preparing a presentation for a senior center about age-related musculoskeletal changes, which of the following changes should be included?
Decreased muscle mass
Thickened vertebral disks
Increased force of isometric contraction
Reduced chest width
The Correct Answer is A
Choice A rationale
Decreased muscle mass is a common age-related musculoskeletal change. As people age, they tend to lose muscle mass due to changes in muscle fiber and decreased physical activity. This can lead to weakness and decreased mobility.
Choice B rationale
Thickened vertebral disks are not typically an age-related change. Instead, the disks often become thinner and less flexible with age, which can lead to conditions like degenerative disk disease.
Choice C rationale
Increased force of isometric contraction is not an age-related musculoskeletal change. In fact, both isometric and isotonic muscle strength tend to decrease with age.
Choice D rationale
Reduced chest width is not typically an age-related musculoskeletal change. However, changes in posture and spinal curvature can affect the shape and function of the chest.

Correct Answer is A
Explanation
Choice A rationale
The rubella vaccine is a live vaccine, which means it contains a weakened version of the virus. Because the virus is still active, live vaccines are not safe for pregnant people. There is a small chance they may pass the virus to the baby. Therefore, it is recommended that adults of childbearing age should avoid getting pregnant for at least four weeks after receiving the MMR vaccine. This is to ensure the safety of both the mother and the baby.
Choice B rationale
This statement is incorrect. The rubella vaccine does not require additional shots after each baby with Rh-positive blood. The rubella vaccine is typically administered in childhood and provides long-term protection.
Choice C rationale
This statement is also incorrect. The rubella vaccine does not require additional shots in 1 month and again in 6 months. The vaccine provides long-term protection and does not typically require frequent boosters.
Choice D rationale
While it’s true that some vaccines can cause side effects such as fever and vomiting, these are not common side effects of the rubella vaccine. Therefore, this statement is not entirely accurate.
Correct Answer is A
Explanation
Choice A rationale
Glipizide is a sulfonylurea medication used in Type 2 Diabetes to sensitize pancreatic beta cells and stimulate insulin release. It helps control blood sugar levels by prompting your pancreas to produce insulin. This medication is effective only in people whose bodies produce insulin naturally.
Choice B rationale
Glipizide does not replace insulin that is not being produced by your pancreas. Instead, it stimulates the pancreas to release insulin.
Choice C rationale
Glipizide does not absorb excess carbohydrates in your system. Its primary action is to stimulate the release of insulin from the pancreas.
Choice D rationale
Glipizide does not prevent your liver from destroying your insulin. Its main function is to stimulate the pancreas to release insulin, which helps control blood sugar levels.
