What is the purpose of evidence-based practice (EBP) in nursing?
To ensure that nurses follow standardized protocols and procedures
To save time by relying on established nursing practices
To provide care based on tradition and personal beliefs
To improve patient outcomes and quality of care
The Correct Answer is D
A. While EBP may involve following standardized protocols that are based on research, its primary purpose is broader. It aims to guide practice based on the best available evidence rather than just following protocols without questioning their efficacy.
B. Although established practices can be efficient, EBP is not primarily about saving time; it’s about ensuring that practices are scientifically validated. Relying solely on established practices without evidence can lead to outdated or ineffective care.
C. While traditions and personal beliefs can inform a nurse’s approach, EBP emphasizes using research and evidence rather than subjective beliefs. This ensures that care is based on what has been shown to be effective.
D. The ultimate goal of evidence-based practice is to enhance patient outcomes, safety, and the overall quality of care. By integrating the best research evidence, clinical expertise, and patient preferences, nurses can provide the most effective and appropriate care.

Correct Answer is A
Explanation
A. As people age, the glands in the ear may produce more cerumen (earwax), and the ear canal may also become narrower, leading to a buildup of wax. This can affect hearing and may require regular cleaning by a healthcare professional.
B. With aging, peripheral vision often decreases due to changes in the retina and other parts of the eye. Older adults may experience difficulties in peripheral awareness, making it harder to detect objects or movements outside their central line of sight.
C. As people age, they may experience decreased sensitivity to touch due to changes in nerve endings and skin elasticity. Many older adults report a reduced sense of touch, which can affect balance and coordination.
D. In fact, older adults typically experience decreased pupil size and a reduced response to changes in light. The pupils may become more fixed and less able to dilate quickly in response to dim light.
Correct Answer is B
Explanation
A. With aging, the tympanic membranes (eardrums) typically become thinner and less flexible, which can affect hearing. Therefore, this choice does not reflect the physiological changes that occur.
B. One of the most common changes in hearing as people age is presbycusis, which often leads to a decreased ability to hear high-frequency sounds. This loss can significantly impact communication and quality of life for older adults.
C. Tinnitus, which is the perception of ringing or buzzing in the ears, often does not decrease with age. In fact, many older adults experience increased tinnitus or persistent tinnitus due to age-related hearing loss or other factors, making this choice incorrect.
D. This is not typically accurate. Older adults often have an increased build-up of ear wax (cerumen) due to changes in ear canal structure and gland function. This can lead to blockages that affect hearing, so this choice does not represent a physiological change commonly observed in older adults.
