Case Studies & Practical Application Flashcards

A CNS notices that post-operative pain is consistently undertreated on a surgical unit despite a standing opioid order. Root cause analysis reveals nurses fear patient addiction. What is the CNS's most effective intervention?

Answer: Design and deliver targeted education distinguishing physical dependence, tolerance, and addiction in post-operative patients

Addressing the underlying knowledge deficit about opioid pharmacology and addiction vs. dependence directly targets the root cause of undertreatment.

A CNS is implementing a sepsis bundle across a 300-bed hospital. Which organizational strategy best ensures sustainable bundle compliance?

Answer: Embed clinical decision support alerts in the EHR, create unit-based champions, and tie compliance to unit quality dashboards

Sustainable compliance requires workflow integration (EHR alerts), social diffusion (champions), and feedback loops (dashboards) — a multifaceted systems approach.

A 72-year-old patient with CHF, CKD stage 3, and type 2 diabetes presents with worsening dyspnea and BNP 1,200 pg/mL. The CNS is asked to advise on diuresis. Which approach is most appropriate?

Answer: Initiate IV furosemide with careful monitoring of creatinine, electrolytes, and urine output, using cardiorenal syndrome framework

Cardiorenal syndrome management requires IV diuresis for decompensated CHF while closely monitoring renal function — avoiding both under- and over-diuresis.

During a mock code review, the CNS observes that nursing staff hesitate to initiate CPR when a physician is present, even after the physician calls for it. What does this most likely represent?

Answer: Authority gradient/hierarchy creating unsafe deference to physicians in emergencies

Authority gradient — the perceived power difference between nurses and physicians — can cause dangerous hesitation in emergencies, a known patient safety issue.

A CNS is developing a clinical practice guideline for central line-associated bloodstream infection (CLABSI) prevention. Which evidence level should form the foundation of the guideline?

Answer: Systematic reviews and meta-analyses of RCTs on CLABSI prevention bundles

Clinical practice guidelines should be built on the highest level of evidence — systematic reviews/meta-analyses of RCTs — per evidence hierarchy frameworks (GRADE, Johns Hopkins, AHRQ).

A post-partum patient develops sudden severe headache, hypertension (BP 165/110), and visual changes on day 3. What condition should the CNS immediately suspect and what is the priority intervention?

Answer: Postpartum preeclampsia/eclampsia; administer IV magnesium sulfate and antihypertensives per protocol

Postpartum preeclampsia can develop up to 6 weeks after delivery; severe features (BP >=160/110, headache, visual changes) require immediate magnesium sulfate for seizure prophylaxis.
