Fidelity in nursing practice primarily refers to:

Choice A rationale
Poor balance and muscle weakness are significant risk factors for falls among older adults. These conditions can make it difficult for individuals to maintain stability and recover from a loss of balance, increasing the likelihood of falls.
Choice B rationale
Vision impairment is a well-known risk factor for falls. Poor vision can make it difficult for individuals to see obstacles and navigate their environment safely, leading to an increased risk of falls.
Choice C rationale
Medications that cause dizziness are a common risk factor for falls. Many medications, including those for blood pressure, pain, and anxiety, can have side effects that affect balance and coordination, increasing the risk of falls.
Choice D rationale
Regular physical activity is not a risk factor for falls. In fact, regular exercise can improve strength, balance, and coordination, reducing the risk of falls. Physical activity is often recommended as a preventive measure to help older adults maintain their mobility and independence.

Choice A rationale
A DNR order does not mean that all medical treatments are withheld. It specifically indicates that CPR will not be performed if the patient’s heart stops.
Choice B rationale
While a DNR order allows for most medical treatments, it does not mean that all treatments are provided. CPR is specifically excluded.
Choice C rationale
A DNR order does not exclude medications. Patients with a DNR order can still receive medications and other treatments.
Choice D rationale
A DNR order means that CPR will not be performed in the event of cardiac arrest, but other medical treatments, including medications and comfort care, can still be provided.
