A client is exhibiting diminished range of motion, loss of flexibility, stiffness, and loss of height. The history and physical findings are associated with age-related changes of which area?

Ligaments.

Bones.

Muscles.

Joints.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Ligaments connect bones and stabilize joints. Age-related changes in ligaments result in decreased elasticity, leading to joint stiffness but not directly causing loss of height.

Choice B rationale

Bones undergo resorption and may lose density with age, leading to osteoporosis. While this contributes to height loss, it is not typically associated with diminished range of motion or flexibility as primary symptoms.

Choice C rationale

Muscles lose mass and strength with aging, a condition known as sarcopenia. This affects flexibility and range of motion but does not lead directly to height loss.

Choice D rationale

Joints are affected by age-related changes such as cartilage wear and synovial fluid reduction, leading to stiffness, loss of flexibility, diminished range of motion, and height loss due to spinal disc compression and vertebral changes.

Correct Answer is B

Explanation

Choice A rationale

Vitiligo is a condition characterized by depigmentation of the skin, leading to white patches. It does not typically affect the fingernails, so pitting on the surface of the nails is not indicative of vitiligo.

Choice B rationale

Psoriasis is a chronic skin condition that often affects the nails, leading to pitting or the appearance of small depressions on the nail surface. Nail psoriasis can also cause discoloration, thickening, and separation of the nail from the nail bed.

Choice C rationale

Melanoma is a type of skin cancer that can affect the nails, causing dark streaks or pigmentation changes. However, pitting on the surface of the nails is not a characteristic feature of melanoma.

Choice D rationale

Diabetes can lead to various nail changes, including thickening and yellowing of the nails, but it does not typically cause pitting on the nail surface. Pitting is more specific to psoriasis.

A. Dysfunction in the cerebrum. B. Dysfunction in the brain stem. C. Dysfunction in the spinal column. D. Dysfunction in the motor cortex.

Correct Answer is B

Explanation

Choice A rationale

Dysfunction in the cerebrum would likely result in different types of posturing, such as decorticate posturing, rather than decerebrate. The cerebrum is involved in controlling voluntary motor functions and damage here typically does not lead to decerebrate posturing.

Choice B rationale

Dysfunction in the brain stem results in decerebrate posturing, characterized by rigid extension of the arms and legs, downward pointing of the toes, and backward arching of the head. The brain stem is crucial for controlling basic life functions and its impairment leads to severe motor response issues.

Choice C rationale

Dysfunction in the spinal column typically does not lead to decerebrate posturing but may lead to different types of paralysis or movement issues depending on the location and severity of the damage.

Choice D rationale

Dysfunction in the motor cortex usually leads to abnormalities in voluntary movement, muscle tone, and coordination rather than decerebrate posturing which is more linked to brain stem issues.
