geriatric nursing exam questions with rationale

Correct Answer: B

Rationale: The correct answer is B because straining to void can lead to increased vagal stimulation, resulting in decreased blood pressure upon standing (orthostatic hypotension). A: age and walker use don't directly increase risk. C: a leg cast may not directly affect blood pressure. D: Premarin use is not a common cause of orthostatic hypotension.

Correct Answer: D

Rationale: The correct answer is D because learning advanced knitting techniques adds to the existing knowledge base of older women. This activity stimulates cognitive functioning, enhances problem-solving skills, and fosters creativity. It also helps maintain mental acuity and memory. Choice A is incorrect because although knitting may involve hand movements, it primarily benefits cognitive functions. Choice B is incorrect as the primary focus is on individual learning rather than group cohesion. Choice C is incorrect as the main purpose of the activity is intellectual growth rather than social interaction.

Correct Answer: A

Rationale: The correct answer is A: Decreased lean body mass and decreased glomerular filtration rate. 1. Decreased lean body mass: With aging, there is a natural decline in muscle mass which can affect the distribution and metabolism of digoxin, potentially increasing its concentration in the body. 2. Decreased glomerular filtration rate: As individuals age, there is a decrease in kidney function, particularly in the glomerular filtration rate, which can lead to decreased excretion of digoxin, resulting in its accumulation and potential toxicity. Therefore, these age-related changes can place the older client at risk for digoxin toxicity. Summary: B: Increased muscle mass and improved renal function - This choice is incorrect as aging is associated with decreased muscle mass and declining renal function. C: Higher levels of albumin and increased drug metabolism - This choice is incorrect as aging is typically associated with decreased albumin levels and slower drug metabolism. D: Decreased hepatic function and increased body fluid

Correct Answer: B

Rationale: The correct answer is B because regular physical activity and joint mobility exercises help improve joint flexibility, reduce pain, and increase strength. This intervention can enhance overall physical function and quality of life for older adults with arthritis. Complete bed rest (A) can lead to muscle weakness and joint stiffness, worsening arthritis symptoms. Increased use of opioid painkillers (C) can have adverse side effects and may not address the root cause of arthritis. Strictly limiting daily activities (D) can lead to decreased mobility and functional decline in older adults.

Correct Answer: C

Rationale: The correct answer is C because consistent routines and environmental modifications have been shown to be the most effective approach in reducing agitation and aggression in older adults with dementia. This approach focuses on providing structure and familiarity, which can help decrease confusion and anxiety in individuals with dementia. Physical restraints (A) are not recommended as they can lead to further agitation and pose risks of injury. Increased sedation with antipsychotics (B) should be used as a last resort due to potential side effects and risks. Ignoring the behavior (D) is not appropriate as it can exacerbate the situation and lead to further distress for the individual.
