Case Studies & Practical Application Flashcards

A CNS is consulting on a 68-year-old patient with COPD exacerbation who develops acute confusion on day 2 of hospitalization. Which assessment approach best reflects CNS competency in the patient/family sphere?

Answer: Perform a systematic delirium evaluation using CAM and identify precipitating factors

The CNS applies advanced assessment skills using validated tools like CAM while identifying reversible causes such as hypoxia, medications, or infection.

During a care conference for a patient with end-stage heart failure, the family insists on full resuscitation despite the patient's documented POLST stating DNR. What is the CNS's priority action?

Answer: Facilitate a structured family meeting to clarify the patient's expressed values and the POLST's legal standing

The CNS facilitates communication between the family and care team, clarifying that a properly executed POLST reflects the patient's autonomous decision and has legal standing.

A CNS reviewing a unit's pressure injury data identifies that Stage II PI rates increased 40% over the last quarter. Using the PDSA cycle, what is the first step?

Answer: Plan: analyze root causes by reviewing care processes, staffing patterns, and documentation

The PDSA cycle begins with the Plan phase — identifying the problem, analyzing root causes, and designing the intervention before implementation.

A staff nurse approaches the CNS saying she believes a colleague is practicing unsafely but fears retaliation for reporting. What is the CNS's best response?

Answer: Provide education on the reporting process, peer support, and the organization's non-retaliation policy, then assist with the report

The CNS supports staff by providing education on safe reporting mechanisms, explaining non-retaliation protections, and assisting the nurse through the process.

A CNS is asked to evaluate a 55-year-old post-CABG patient with new-onset atrial fibrillation and a heart rate of 132 bpm. Which pharmacological intervention is most appropriate for rate control in this hemodynamically stable patient?

Answer: Metoprolol tartrate IV for rate control targeting HR <110 bpm

IV beta-blockers (metoprolol) are first-line for rate control in hemodynamically stable post-surgical AF; target HR <110 bpm per AHA/ACC guidelines.

The CNS is evaluating outcomes of a newly implemented early mobility protocol. Which metric best demonstrates the protocol's impact on patient outcomes?

Answer: Reduction in ICU-acquired weakness incidence and ventilator days

Clinical outcome metrics (ICU-acquired weakness incidence, ventilator days) directly measure the protocol's impact on patient health, which is the CNS's primary outcome focus.
