A nurse is reinforcing teaching with an older adult client about physical changes that occur with aging. Which of the following should the nurse include as an expected age-related change?

d. Increased joint stiffness due to loss of elasticity in joint cartilage. Explanation: The correct answer is d. Increased joint stiffness due to loss of elasticity in joint cartilage. When teaching an older adult client about age-related changes, it is important for the nurse to provide accurate and relevant information. Joint stiffness is a commonly experienced age-related change that occurs due to the natural loss of elasticity in joint cartilage. As people age, their joints may become stiffer and less flexible, making movements and activities more challenging. Option a is not the correct answer. Increased nail growth due to the buildup of calcium deposits is not an expected age-related change. Nail growth is primarily determined by factors such as genetics, overall health, and nutritional status, rather than calcium deposits. Option b is not the correct answer. Increased perspiration due to overproduction by the sweat glands is not an expected age-related change. In fact, older adults may experience a decrease in the production of sweat, which can make them more susceptible to heat-related illnesses and dehydration. Option c is not the correct answer. Increased cardiac output due to weakened heart walls is not an expected age-related change. With aging, the heart muscles may become stiffer and less efficient, leading to a decrease in cardiac output rather than an increase. By focusing on the expected age-related change of increased joint stiffness due to loss of elasticity in joint cartilage, the nurse can provide accurate information and help the older adult client understand and manage this common aspect of the aging process.
