In the process of developing evidence-based practice, after reviewing current research studies, the next step is to:

Correct Answer: A

Rationale: Evidence-based practice (EBP) follows a systematic process: ask, acquire, appraise, apply, assess. After reviewing research (appraise), validating findings in practice is next testing applicability (e.g., a new dressing technique) in real settings. Using data for safety or evaluating outcomes follows application. Searching for evidence is prior. Validation ensures relevance before broader use, aligning with EBP models like Johns Hopkins, making it the correct next step for LPNs integrating research into care.

Correct Answer: B

Rationale: Prevention focuses on avoiding illness onset. Vision screenings detect issues early (e.g., glaucoma), aligning with primary prevention per CDC guidelines. Wound dressing is treatment, not prevention. Referrals and prenatal care are valuable but secondary or specific. Screenings proactively reduce disease burden across populations, a key nursing role, making it the correct and most effective prevention activity.

Correct Answer: A

Rationale: Homeostasis is the body's dynamic balance adjusting to changes like temperature or blood sugar, per physiology texts. Disturbed equilibrium disrupts it, not defines it. Stressor reaction is a process, not the state. Static condition contradicts its adaptability. Constant adjustment (e.g., sweating to cool) maintains stability, a concept LPNs monitor (e.g., vitals), making this the correct and most accurate description.

Correct Answer: B

Rationale: Bloodless surgery avoids transfusions. Volume expanders e.g., saline replace fluid without blood, per surgical protocols. Epogen boosts red cells pre-op, not during. Hypothermia preserves oxygen, not fluid-focused. Banking blood implies transfusion, contradicting bloodless aims. Expanders maintain circulation, a common LPN-monitored intervention, making this the correct and most relevant option.

Correct Answer: B

Rationale: Discharge post-same-day surgery requires stability. Alertness, ambulation, and bladder emptying confirm recovery per ambulatory surgery guidelines ensuring safety home. A driver is logistical, not readiness. Pain control and nausea resolution are partial. Full function (mental, motor, urinary) is the standard, an LPN discharge check, making it the correct criterion.
