A nurse is assessing an older adult client who has sarcopenia.
The nurse knows that this condition is characterized by which of the following?
Loss of bone mass and strength
Loss of muscle mass and strength
Loss of joint flexibility and range of motion.
Loss of skin elasticity and moisture.
The Correct Answer is B
The correct answer is B.
Loss of muscle mass and strength. Sarcopenia is a condition that affects older adults and causes a progressive decline in skeletal muscle mass, strength, and function. This can lead to an increased risk of falls, fractures, disability, and mortality.
Choice A is wrong because the loss of bone mass and strength is called osteoporosis, not sarcopenia. Osteoporosis is a condition that affects the density and quality of bones, making them more prone to fracture.
Choice C is wrong because loss of joint flexibility and range of motion is called arthritis, not sarcopenia.
Arthritis is a term that refers to inflammation of the joints, which can cause pain, stiffness, swelling, and reduced mobility.
Choice D is wrong because loss of skin elasticity and moisture is called skin aging, not sarcopenia.
Skin aging is a process that involves changes in the structure and function of the skin, such as wrinkles, sagging, dryness, and decreased wound healing.
Normal ranges for muscle mass and strength vary depending on age, sex, body size, and physical activity level. However, some general indicators of sarcopenia include:.
• A muscle mass index (muscle mass divided by height squared) below 7.26 kg/m2 for men and 5.45 kg/m2 for women.
• A handgrip strength below 30 kg for men and 20 kg for women.
• A gait speed below 0.8 m/s for both sexes.

Correct Answer is A
Explanation
The correct answer is A.
Decreased metabolic rate.This is because the metabolic rate is the amount of energy that the body uses to maintain its functions, and it tends to decline with age due to various factors, such as loss of muscle mass, reduced activity, hormonal changes, and decreased thyroid function.
A lower metabolic rate means that the body produces less heat and therefore feels colder more easily.
Choice B is wrong because increased blood pressure is not a normal physiological change with aging, but rather a risk factor for cardiovascular diseases that can be influenced by lifestyle, genetics, and other factors.
Choice C is wrong because increased sweat gland activity is not a normal physiological change with aging, but rather a sign of hyperhidrosis, which is a condition that causes excessive sweating due to overactive sweat glands.Sweat glands actually decrease in number and function with age, which can impair thermoregulation and increase the risk of heat-related illnesses.
Choice D is wrong because decreased body fat is not a normal physiological change with aging, but rather a result of malnutrition, illness, or other causes.Body fat actually tends to increase with age, especially in the abdominal region, due to hormonal changes, reduced physical activity, and lower metabolic rate.
Body fat can act as an insulator and help maintain body temperature.
Normal ranges for metabolic rate vary depending on age, sex, body size, activity level, and other factors.
A general estimate for resting metabolic rate (RMR) is 10 calories per kilogram of body weight per day for men and 9 calories per kilogram of body weight per day for women.
However, this may not reflect the actual metabolic rate of an individual, as it does not account for the effects of food intake, exercise, or environmental factors.
Therefore, it is better to measure metabolic rate using indirect calorimetry or other methods that can capture these variables.
Correct Answer is ["A","B","C"]
Explanation
The correct answer is A, B and C.
These are the factors that increase the risk of respiratory infections in elderly patients:.
• Decreased immune response: Elderly patients have a weaker immune system that makes them more susceptible to viral and bacterial infections.They also have a poor response to respiratory vaccines.
• Decreased chest wall compliance: Elderly patients have reduced elasticity of the lungs and chest wall, which makes it harder for them to breathe and expel mucus.
• Decreased alveolar surface area: Elderly patients have fewer and larger alveoli, which reduces the gas exchange area and oxygen diffusion capacity.
Choice D is wrong because decreased oxygen saturation is not a risk factor, but a consequence of respiratory infections.
Choice E is wrong because decreased bronchial dilation is not a specific factor for elderly patients, but a common feature of obstructive lung diseases.
Normal ranges for oxygen saturation are 95-100% and for bronchial dilation are variable depending on the type and severity of the disease.
