Which of the following is a benefit of using evidence-based practice in nursing?
Increased reliance on untested medications.
Increased use of trial-and-error methods.
Improvement in patient outcomes and care quality.
Reduction in healthcare costs only.
The Correct Answer is C
A. Increased reliance on untested medications: Evidence-based practice (EBP) specifically seeks to eliminate the use of untested or unproven therapies. It mandates that all interventions be supported by rigorous scientific data and clinical trials. This increases patient safety by ensuring that medications have a proven efficacy and safety profile.
B. Increased use of trial-and-error methods: Trial-and-error is the antithesis of EBP, as it relies on unsystematic attempts rather than proven research. EBP reduces the uncertainty of clinical decision-making by providing a structured framework based on the best available data. It moves nursing away from guesswork toward standardized, high-quality care.
C. Improvement in patient outcomes and care quality: By utilizing interventions that have been scientifically validated, EBP ensures that patients receive the most effective treatments available. This leads to faster recovery times, fewer complications, and a higher standard of clinical excellence. It is the primary driver of modern healthcare improvement.
D. Reduction in healthcare costs only: While EBP can lead to cost savings by reducing ineffective treatments and hospital stays, its primary focus is on the quality of patient care. Financial benefits are a secondary positive outcome of improved clinical efficiency. The core benefit remains the enhancement of the patient's health and safety.

Correct Answer is C
Explanation
A. Tolerance leads to compulsive drug-seeking behavior:Compulsive drug-seeking behavior is the hallmark of addiction, which is a psychological and behavioral disorder. Tolerance is a purely physiological adaptation where the body requires higher doses of a drug to achieve the same effect. Tolerance does not inherently mean a person will develop addictive behaviors.
B. Physical dependence and addiction are the same:Physical dependence involves the occurrence of withdrawal symptoms when a drug is stopped, whereas addiction is characterized by the psychological drive to use a substance despite harm. A patient can be physically dependent on a medication without being addicted to it. These are distinct clinical phenomena.
C. Addiction involves compulsive use regardless of harm:Addiction is defined by impaired control over drug use, craving, and continued use despite negative physical, social, or legal consequences. It involves a complex interplay of genetics, brain chemistry, and environment. It is a chronic disease of brain reward and motivation.
D. Tolerance is characterized by withdrawal symptoms upon cessation:Withdrawal is the clinical manifestation of physical dependence, not tolerance. Tolerance specifically refers to the diminishing effect of a drug over time with repeated use. While they often occur together in long-term opioid use, they represent different physiological processes.
Correct Answer is A
Explanation
A. Check the neurovascular status of the affected limb:Tingling, or paresthesia, is one of the "six Ps" of neurovascular compromise and can indicate nerve compression or compartment syndrome. The nurse must immediately assess pulses, sensation, and capillary refill to ensure limb viability. This physical assessment takes priority over pharmacological or comfort measures.
B. Administer pain medication:While the patient may be in discomfort, administering analgesics without a thorough assessment could mask symptoms of serious complications. Paresthesia is distinct from nociceptive pain and requires a different diagnostic focus. Safety must be established through assessment before symptomatic treatment is initiated.
C. Notify the orthopedic surgeon immediately:Communication with the surgeon is necessary, but the nurse must first collect objective data to provide a comprehensive report. Immediate notification without an assessment prevents the surgeon from making an informed decision about the urgency of the intervention. Assessment must precede notification in clinical workflows.
D. Apply ice to the operative site:Cryotherapy is used to reduce swelling and provide localized analgesia. However, if the tingling is caused by excessive pressure from a dressing or internal swelling, ice will not resolve the underlying nerve compression. It is a supportive measure that follows a definitive neurovascular evaluation.
