The gradual and progressive condition that causes a decline in memory and the ability to perform activities of daily living is called dementia. True or false?

Choice A reason: Joint deformity is an unexpected musculoskeletal finding, indicating conditions like arthritis or trauma, requiring intervention. Symmetrical movement is normal. Assuming deformity is expected risks neglecting serious issues, delaying treatments like physical therapy or surgery, critical for restoring function and preventing disability in affected patients.

Choice B reason: Symmetrical degrees of movement are expected in musculoskeletal assessments, indicating normal joint function and muscle strength. Asymmetry, deformity, or limited movement are abnormal. Recognizing this ensures focus on true abnormalities, guiding accurate diagnosis and interventions for musculoskeletal issues, critical for maintaining mobility and function in patients.

Choice C reason: Limited ability to complete maneuvers is an unexpected finding, suggesting joint stiffness, pain, or weakness, possibly from arthritis or injury. Symmetrical movement is normal. Assuming this is expected risks missing treatable conditions, delaying interventions like therapy or medication, critical for improving musculoskeletal function and patient quality of life.

Choice D reason: Differences in movement between right and left sides are unexpected, indicating asymmetry from conditions like stroke or injury. Symmetrical movement is normal. Assuming asymmetry is expected risks overlooking neurological or musculoskeletal issues, delaying diagnosis and rehabilitation, critical for restoring balanced function in patients with movement disparities.

Choice A reason: Assessing pupils tests cranial nerves II (optic) and III (oculomotor), evaluating visual acuity and pupillary response, not cranial nerve I (olfactory), which governs smell. Pupil assessment is irrelevant to olfactory function, making this choice incorrect for testing the sense of smell.

Choice B reason: Cranial nerve I, the olfactory nerve, is responsible for the sense of smell. Instructing the client to identify a scent, such as coffee or vanilla, directly tests this nerve’s function. This is a standard neurological assessment method to evaluate olfactory integrity, making it the correct choice.

Choice C reason: Performing facial expressions tests cranial nerve VII (facial), which controls facial muscle movement. This is unrelated to cranial nerve I, which solely mediates olfaction. Facial expression assessment cannot evaluate smell, rendering this choice inappropriate for the specified cranial nerve test.

Choice D reason: Reading the Snellen chart tests cranial nerve II (optic) for visual acuity, not cranial nerve I, which is dedicated to smell perception. Visual testing does not assess olfactory function, making this choice incorrect for evaluating the olfactory nerve’s sensory capabilities.
