Which assessment finding of an older adult client should the nurse associate with normal aging?

A. Kyphosis: A rounding of the upper back, causing a hunchback appearance. While it can also be caused by other conditions, a mild kyphosis is a common finding in older adults due to weakening muscles and spinal compression. B. Barrel chest: This refers to a chest that is fixed in an outward position, often caused by chronic obstructive pulmonary disease (COPD) or other lung conditions. C. Lordosis: An exaggerated inward curve of the lower back, which is not a typical feature of normal aging. D. Pectus excavatum: A sunken appearance of the chest wall, usually a congenital condition present from birth.
