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

Answer and Explanation

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 Relying solely on established practices without evidence can lead to outdated or ineffective care.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 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.

A. Place two fingers in the client's mouth. B. Hold the toothbrush at a 90° angle. C. Vigorously brush the client's teeth. D. Turn the client to the side.

Correct Answer is D

Explanation

A. This action is not appropriate as it could stimulate the gag reflex and lead to choking or aspiration. It does not contribute to effective oral care. Instead, gentle techniques using appropriate tools should be used to clean the mouth.
B. Holding the toothbrush at a 90° angle can be effective for brushing teeth as it allows for better access to the surfaces of the teeth. However, for an unconscious patient, this angle might not be practical or safe depending on the circumstances.
C. Vigorous brushing is not recommended, especially for an unconscious client. It could cause damage to the gums, lead to discomfort, or risk aspiration of fluids. Gentle brushing is advised to clean the teeth and gums without causing injury.
D. Turning the client to the side helps prevent aspiration of saliva or any fluids that may be in the mouth. It also provides better access for oral care and minimizes the risk of choking. This position is often recommended for unconscious patients to maintain their safety during oral care.
