INTERACTIVE SAMPLE QUESTION · MANAGEMENT OF CARE Click an option below 👇

During the night shift, Registered Nurse (RN) Michael Chen is supervising assistive personnel (AP) caring for 4 clients, including Mr. Robert Kim, a 68-year-old recovering from an acute stroke with mild dysphagia. The AP reports that Mr. Kim is asking for water and appears very thirsty. The client has an active provider order for nothing by mouth (NPO) pending a formal swallowing evaluation in the morning. Which action by the RN represents appropriate supervision?

Clinical Rationale (Correct Answer: D)

Why D is correct: A post-stroke client with mild dysphagia who is NPO pending a formal swallow evaluation is at high risk for aspiration. Maintaining NPO status is essential for airway safety. Frequent oral care moistens mucous membranes safely without introducing fluid bolus risk.

Why A & B are incorrect: Straws propel liquid rapidly to the posterior pharynx, increasing aspiration risk, and crushed ice melts into thin liquid—both violate NPO precautions.
Why C is incorrect: Collaborating with the provider is appropriate when clinically indicated, but requesting oral fluids before the scheduled swallowing evaluation compromises client safety; maintaining NPO precautions and providing oral care is the appropriate nursing action.

Our Content Development & Quality Assurance Process

Informed by the 2026 NCSBN Test Plan · Transparent AI-Assisted Workflow

KeyBrainer practice questions, clinical scenarios, and option-by-option rationales are drafted and checked using multi-stage AI workflows and released by KeyBrainer. Every question is mapped to the 8 client-needs categories of the 2026 NCSBN NCLEX-RN® Test Plan (effective April 2026) and includes explicit rationales for both correct and incorrect options.

Questions and rationales have not each been reviewed or signed off by a licensed nurse or other clinician, and AI can make mistakes. Check clinical facts against current authoritative sources. They are not official NCLEX® questions.
