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

Answer and Explanation

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 C

Explanation

Choice A rationale

A sweat test is used to diagnose cystic fibrosis, a genetic disorder that affects the lungs and digestive system. It is not used to diagnose pernicious anemia.

Choice B rationale

Haptoglobin is a protein produced by the liver that binds to hemoglobin in the blood to prevent it from being excreted through the kidneys. While it can be used to diagnose conditions that cause the destruction of red blood cells, it is not used to diagnose pernicious anemia.

Choice C rationale

The Schilling test is used to determine whether the body absorbs vitamin B12 normally, which is crucial for the diagnosis of pernicious anemia. Pernicious anemia is a condition where the body is unable to absorb vitamin B12 due to a lack of intrinsic factor, a protein made in the stomach.

Choice D rationale

Antinuclear antibodies (ANAs) are a type of autoantibody that can attack the body’s own tissues. While they can be present in various autoimmune diseases, they are not used to diagnose pernicious anemia.

A. Fetal motion. B. Fetal neck translucency. C. Fetal gender. D. Fetal breathing. E. Amniotic fluid volume.

Correct Answer is ["A","D","E"]

Explanation

Choice A rationale

Fetal motion is indeed evaluated during a biophysical profile. It assesses the health of the baby by observing its movements16.

Choice B rationale

Fetal neck translucency is not evaluated during a biophysical profile. It is usually measured during an ultrasound examination in the first trimester of pregnancy as a part of screening for chromosomal abnormalities.

Choice C rationale

Fetal gender is not evaluated during a biophysical profile. The focus of a biophysical profile is on the baby’s health, not its gender16.

Choice D rationale

Fetal breathing is indeed evaluated during a biophysical profile. It assesses the health of the baby by observing its breathing movements16.

Choice E rationale

Amniotic fluid volume is indeed evaluated during a biophysical profile. It assesses the health of the baby by measuring the amount of amniotic fluid surrounding the fetus in the uterus16.
