What is the purpose of instructing the client to move the walker forward 6 to 8 inches, setting it down with all four feet on the floor when ambulating?
To avoid putting pressure on the client's stronger leg
To ensure proper positioning of the hands on the walker
To provide support for the client's weight while moving their weaker leg
To maintain the client's center of gravity close to the body
The Correct Answer is C
A. The goal is not to avoid pressure on the stronger leg; rather, the walker is used to assist with balance and support for both legs. The client typically puts weight on both legs when using the walker, especially when moving it forward.
B. While proper hand positioning is important for stability, the specific instruction to move the walker forward 6 to 8 inches is primarily focused on facilitating safe movement and balance, rather than just ensuring hand positioning. Therefore, this is not the main purpose.
C. Moving the walker forward provides a stable base of support before the client steps forward with their weaker leg. This technique allows the client to safely shift their weight onto the walker, minimizing the risk of falls and ensuring adequate support during ambulation.
D. While maintaining the center of gravity is important for balance, the specific instruction to move the walker forward 6 to 8 inches is primarily about creating a safe distance to support the client’s weight. This action does help with balance, but it’s not the primary reason for that specific movement.

Correct Answer is B
Explanation
A. Glaucoma typically affects peripheral vision first and may lead to tunnel vision as the disease progresses. While it can cause significant vision loss, it is not primarily characterized by a decrease in central vision.
B. Macular degeneration specifically affects the central part of the retina (the macula), leading to a loss of central vision while peripheral vision remains intact. It is the most common cause of vision loss in older adults and directly correlates with the symptom described.
C. Diabetic retinopathy primarily affects the blood vessels in the retina and can lead to various vision problems, including blurred vision, floaters, and even blindness. However, it does not exclusively cause a decrease in central vision; it often affects both central and peripheral vision.
D. Cataracts typically cause cloudy or blurred vision but do not specifically lead to a decrease in central vision alone. They may affect overall vision clarity, including both central and peripheral vision, but the primary symptom is a general haziness rather than a focused loss of central vision.
Correct Answer is D
Explanation
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.
