geriatric nursing exam questions with rationale

Correct Answer: B

Rationale: The correct answer is B: Low calcium intake. Osteoporosis is a condition characterized by weakened bones, making them more susceptible to fractures. Calcium is essential for bone health, and a low intake can lead to decreased bone density and increased risk of osteoporosis. Physical activity, while beneficial for overall health, is not a significant risk factor for osteoporosis. High alcohol consumption can contribute to bone loss but is not as significant as low calcium intake. Genetics play a role in predisposing individuals to osteoporosis, but it is not a modifiable risk factor like low calcium intake. Thus, B is the correct answer.

Correct Answer: C

Rationale: The correct answer is C because it provides inaccurate information. Osteoarthritis commonly affects weight-bearing joints like the knees and hips, not the hands, elbows, and shoulders as stated. The other choices are incorrect due to the following reasons: A: Correct - describes osteoarthritis B: Incorrect - describes rheumatoid arthritis D: Incorrect - describes risk factors for osteoarthritis, not rheumatoid arthritis.

Correct Answer: B

Rationale: The correct answer is B: Fewer taste buds. As people age, they tend to have fewer taste buds, leading to a decreased ability to taste food. This can result in a loss of interest in eating, which may contribute to anorexia and weight loss. Excessive saliva (A) does not directly contribute to anorexia or weight loss. Wearing dentures (C) may affect chewing but is not a major factor in anorexia. Softened tooth enamel (D) is more related to dental health rather than appetite and weight loss.

Correct Answer: A

Rationale: The correct answer is A because it accurately reflects the multifactorial nature of diabetes in older adults. Age-related changes, coupled with lifestyle factors like poor diet and lack of exercise, contribute to the high incidence of diabetes in this population. This statement acknowledges the complexity of diabetes in older adults. B is incorrect because while nurses should have knowledge about diabetes in older adults, the statement does not specifically address the multifactorial nature of the disease in this population. C is incorrect because ethnicity can indeed play a role in diabetes risk and should not be dismissed outright. D is incorrect because the development of diabetes is not considered a normal age-related change; it is a medical condition that can be influenced by various factors.

Correct Answer: B

Rationale: The correct answer is B: Difficulty standing up from a seated position. This is a key indicator of potential sarcopenia because sarcopenia is characterized by age-related loss of muscle mass and strength. Difficulty standing up from a seated position can be attributed to muscle weakness, which is a common symptom of sarcopenia. Unintentional weight loss (A) can be a sign of various health issues, not specific to sarcopenia. Loss of appetite (C) can also be caused by a range of factors, not exclusive to sarcopenia. Increased body fat percentage (D) is not a direct indicator of sarcopenia, as the condition primarily involves muscle loss rather than increased body fat.
