LPN Fundamentals Practice Test Questions
Question 1 of 5
What is the relevance of a code of ethics for nurses?
Correct Answer: C
Rationale: A nursing code of ethics, like Kenya's or ANA's, defines principles autonomy, justice, beneficence shaping client care delivery. It guides decisions (e.g., respecting refusal), ensuring ethical practice. Improving universal health is an outcome, not the code's purpose, which focuses on conduct. Providing identical care misreads ethics; it ensures fairness, not uniformity care varies by need. Protecting nurses' desires prioritizes self-interest, not clients, clashing with the code's intent. Defining principles offers a moral compass, enabling nurses to navigate dilemmas, uphold trust, and deliver client-centered care, making this the code's core relevance.
Question 2 of 5
A client with a bowel resection and anastomosis returns to his room with an NG tube attached to intermittent suction. Which of the following observations indicates that the nasogastric suction is working properly?
Correct Answer: A
Rationale: A soft abdomen indicates effective nasogastric suction post-bowel resection, decompressing the stomach and intestines, preventing distension or leakage at the anastomosis site. Swallowing ability, bowel sounds, or dressing condition don't directly confirm suction efficacy distension relief does. Nurses monitor this to ensure gastrointestinal rest, reducing complications like ileus or suture strain, supporting healing in a client recovering from major abdominal surgery.
Question 3 of 5
The nurse is caring for a client with a spinal cord injury who is at risk for deep vein thrombosis (DVT). Which intervention should the nurse implement?
Correct Answer: A
Rationale: Sequential compression devices (
A) prevent DVT in immobile SCI patients. Active exercise (
B) isn't feasible. Anticoagulants (
C) need orders. Massage (
D) risks emboli. A is correct.
Rationale: Compression enhances venous return, reducing stasis, per DVT prophylaxis in SCI, a standard intervention.
Question 4 of 5
The foundation of research is based on which of the following:
Correct Answer: D
Rationale: The scientific method defining a question, hypothesizing, experimenting, analyzing, and concluding forms research's foundation, providing a structured, replicable approach to generate reliable knowledge. In nursing, it underpins evidence-based practice, like testing a new wound care protocol. Experience informs research but lacks systematic rigor alone; it's subjective and anecdotal. Problem-solving is a skill applied within research, not its base lacking the method's objectivity. Critical thinking is essential for interpreting data or designing studies, but it's a tool, not the framework. The scientific method's disciplined process ensures findings are valid and generalizable, distinguishing research from intuition or trial-and-error. It's the gold standard for building nursing knowledge, validating interventions, and improving patient outcomes, making it the foundational element of research.
Question 5 of 5
The primary respiratory center
Correct Answer: A
Rationale: The medulla oblongata is the primary respiratory center e.g., initiating each breath via its neurons. Pons modulates, carotid/aortic bodies sense O2/CO2. Damage here stops breathing nurses monitor this e.g., in stroke for life-sustaining function, per neurological control.
