An elderly resident of a long-term care facility frequently wakes up to urinate during the night. What physiological change associated with normal aging could be the cause of this?
Reduced kidney ability to concentrate urine.
Lower fluid intake during daytime hours.
Enhanced bladder contractility leading to urinary stasis.
Increased bladder muscle tone leading to frequent urination.
The Correct Answer is A
Choice A rationale:
Reduced kidney ability to concentrate urine is a common physiological change associated with normal aging. This is due to several factors, including:
Decreased glomerular filtration rate (GFR): The kidneys filter waste products from the blood. As we age, the number of functioning nephrons (filtering units) in the kidneys decreases, leading to a decline in GFR. This means that the kidneys are less able to filter waste products and concentrate urine.
Decreased renal blood flow: Blood flow to the kidneys also decreases with age. This further reduces the kidneys' ability to filter waste products and concentrate urine.
Decreased tubular function: The tubules in the kidneys are responsible for reabsorbing water and electrolytes from the urine. As we age, the function of the tubules also declines, leading to a decrease in the ability to concentrate urine.
As a result of these changes, older adults often produce more urine, even at night. This can lead to nocturia, which is the need to wake up to urinate two or more times per night.
Choice B rationale:
Lower fluid intake during daytime hours can also contribute to nocturia, but it is not a direct physiological change associated with normal aging. Older adults may drink less fluids during the day for a variety of reasons, such as decreased thirst sensation, fear of incontinence, or limited access to fluids. However, even if they maintain adequate fluid intake during the day, they may still experience nocturia due to the reduced ability of their kidneys to concentrate urine.
Choice C rationale:
Enhanced bladder contractility leading to urinary stasis is not a typical physiological change associated with normal aging. In fact, bladder contractility often decreases with age, which can lead to difficulty emptying the bladder completely. This can contribute to urinary frequency and urgency, but it is not typically a cause of nocturia.
Choice D rationale:
Increased bladder muscle tone leading to frequent urination is also not a typical physiological change associated with normal aging. Bladder muscle tone may decrease with age, which can lead to difficulty emptying the bladder completely. However, it is not typically a cause of nocturia.

Correct Answer is D
Explanation
Choice A rationale:
Chronic health promotion focuses on managing and preventing complications of long-term, ongoing conditions. The nurse's talk is not addressing a specific chronic condition or its management, so it does not fall under this category.
Choice B rationale:
Tertiary health promotion aims to minimize the impact of an existing disease or disability and restore function as much as possible. The nurse's talk is not addressing a current disease or disability, but rather preventing them from occurring in the first place, so it does not fall under this category.
Choice C rationale:
Secondary health promotion focuses on early detection and treatment of diseases to prevent or slow their progression. The nurse's talk is not focused on early detection or treatment of specific diseases, but rather on preventing them from developing in the first place, so it does not fall under this category.
Choice D rationale:
Primary health promotion emphasizes preventing diseases and promoting overall wellness before any health problems arise. This aligns directly with the nurse's talk on diet and exercise, as these are key lifestyle factors that can significantly reduce the risk of many chronic diseases and promote overall health.
Here's a breakdown of why this is primary health promotion:
Focus on prevention: The talk is not about managing existing conditions or detecting diseases early; it's about preventing them from occurring in the first place.
Addressing root causes: Diet and exercise are fundamental factors that influence overall health and can contribute to the development of many chronic diseases. By addressing these root causes, the nurse is working to prevent these diseases from developing.
Promoting healthy behaviors: The talk encourages individuals to adopt healthy behaviors that can have a lasting impact on their health. This aligns with primary health promotion's focus on empowering individuals to take control of their own health.
Correct Answer is A
Explanation
Socio-cultural dimension encompasses the social and cultural influences that shape an individual's health beliefs, behaviors, and experiences. It includes factors such as:
Social support systems: The mother's act of seeking support from other parents of children with asthma demonstrates her utilization of a social support system. This is a crucial aspect of the socio-cultural dimension, as strong social connections can provide emotional support, practical assistance, and access to information and resources.
Cultural norms and values: Cultural beliefs about health, illness, and coping mechanisms can influence how individuals seek help and manage their health conditions. The mother's decision to seek support from other parents may be influenced by cultural norms that value community and shared experiences.
Health disparities: Socio-cultural factors can contribute to health disparities, which are differences in health outcomes among different social groups. Understanding the socio-cultural dimension is essential for addressing these disparities and promoting health equity.
Choice B: The intellectual and spiritual dimension focuses on an individual's beliefs, values, and meaning-making processes. While these factors can influence how individuals cope with illness, they are not directly related to the mother's act of seeking support from other parents.
Choice C: The physical dimension encompasses an individual's biological makeup and physical health status. While the child's asthma is a physical condition, the mother's act of seeking support is a social behavior that falls within the socio-cultural dimension.
Choice D: The environmental dimension includes factors in the physical environment that can affect health, such as air quality, housing conditions, and access to healthcare. While these factors can play a role in asthma management, they are not directly related to the mother's decision to seek support from other parents.
