LPN Fundamentals of Nursing Course Questions
Question 1 of 5
Which of the following is the correct interpretation of the ERROR OF PARALLAX
Correct Answer: B
Rationale: Parallax error misaligns eye level with meniscus e.g., higher eyes read lower (false low), lower read higher. Eye-level accuracy is key. Nurses position e.g., meniscus height for true BP, per precision.
Question 2 of 5
The pancreas secretes the following hormones except
Correct Answer: D
Rationale: The pancreas secretes insulin, glucagon, somatostatin e.g., sugar control unlike cortisol (adrenals). Nurses know e.g., diabetes for roles, per physiology.
Question 3 of 5
Evidence-based care emphasizes decision making based on the best available evidence and:
Correct Answer: A
Rationale: Evidence-based care revolutionizes nursing by grounding decisions in the best available evidence, paired with the use of outcome studies to guide practice. This approach integrates research findings such as clinical trials or systematic reviews with patient outcomes, ensuring interventions are effective and measurable, not just theoretical. Specialty knowledge, while useful, is narrower and expert-driven, lacking the broad research base of evidence-based practice. The traditional medical model relies on established routines, often without current validation, while economic concerns prioritize cost over efficacy, neither aligning with this method's focus. Outcome studies provide concrete data, like reduced recovery times or lower infection rates, allowing nurses to adapt care dynamically. This shift enhances quality, safety, and patient-centeredness, moving nursing beyond intuition or tradition to a scientifically robust framework that improves health delivery across diverse settings.
Question 4 of 5
A nurse is planning to participate in a research project and is looking for information about what is already known about the topic. The nurse is involved in which step of the research process?
Correct Answer: B
Rationale: In the research process, the scientific literature review seeking what's already known follows problem identification and precedes framework selection. Here, the nurse gathers existing studies on a topic, like pain management, to avoid redundancy and build on prior work. Identifying the problem area defines the issue, triggering the review. The theoretical framework then guides variable relationships, while the problem statement sets direction. The review synthesizes findings like opioid alternatives' efficacy informing hypotheses and methods. This step ensures research is grounded, efficient, and relevant, preventing duplication and positioning the nurse to contribute meaningfully to nursing knowledge, aligning with evidence-based practice's emphasis on informed inquiry.
Question 5 of 5
A nurse is planning a health fair in the community to highlight promotion and prevention of the leading cause of death in the United States. Which disease process should the nurse address?
Correct Answer: C
Rationale: Coronary artery disease (CAD) is the U.S.'s leading killer, per CDC, making it the nurse's focus for a health fair on prevention and promotion. CAD artery blockages causing heart attacks outpaces lung cancer, emphysema, and strokes in mortality, driven by risks like hypertension or smoking. Addressing it involves teaching heart-healthy habits diet, exercise primary prevention to stop onset, vital in nursing's public health role. Lung cancer and emphysema, though serious, trail CAD, while strokes (cerebrovascular accidents) rank lower. A fair targeting CAD could screen cholesterol or promote activity, cutting its toll over 600,000 deaths yearly aligning with nursing's aim to tackle top health threats, enhancing community wellness through education and early action.
