A nurse is evaluating a client who is 70 years old for signs of dehydration.

Which of the following findings should the nurse expect?

Increased skin turgor.

Decreased pulse rate

Increased urine output.

Decreased mental status.

Answer and Explanation

The Correct Answer is D

The correct answer is D.

Decreased mental status. Dehydration in elderly people can cause confusion, disorientation, or drowsiness due to the loss of water and electrolytes from the body.

These symptoms can affect the cognitive function and alertness of the client. Dehydration can also lead to complications such as kidney problems, electrolyte imbalances, or low blood pressure.

Choice A is wrong because increased skin turgor is not a sign of dehydration.

Skin turgor is the ability of the skin to return to its normal shape after being pinched or pulled. Dehydration causes decreased skin turgor, meaning the skin stays tented or wrinkled after being pinched.

Choice B is wrong because decreased pulse rate is not a sign of dehydration. Dehydration causes increased pulse rate, as the heart has to work harder to pump blood to the vital organs when there is less fluid in the body.

Choice C is wrong because increased urine output is not a sign of dehydration. Dehydration causes decreased urine output, as the kidneys try to conserve water and produce more concentrated urine.

The urine may also be darker in color than normal.

Normal ranges for fluid intake and output vary depending on age, weight, activity level, and health status.

However, a general guideline is to drink at least eight 8-ounce glasses of water per day and produce at least 30 mL of urine per hour.

Correct Answer is B

Explanation

The correct answer isB.

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 calledosteoporosis, 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 calledarthritis, 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 calledskin 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.

A. Decreased metabolic rate B. Increased blood pressure C. Increased sweat gland activity. D. Decreased body fat.

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.
