1. As an AOCNS, you are implementing an evidence based practice change to
reduce chemotherapy induced nausea and vomiting (CINV). What framework
guides the integration of clinical expertise, patient values, and best research
evidence?
Answer: The Melnyk & Fineout Overholt or Iowa Model of Evidence Based
Practice, emphasizing the triad of clinical expertise, patient preferences, and
research evidence.
Rationale: The AOCNS role is to translate evidence into practice. This
requires organizational assessment, stakeholder buy in, piloting, and outcome
measurement, using a structured EBP model to sustain change.
2. A new oncology nurse expresses moral distress after a family insists on
continuing aggressive chemotherapy for a patient with end stage cancer. What is
the CNS's primary role in addressing this?
Answer: Facilitate an ethics consultation and provide staff debriefing using
the 4 Box Method (medical indications, patient preferences, quality of life,
contextual features).
Rationale: The CNS navigates complex ethical issues. Moral distress arises
from knowing the right action but being constrained. The CNS supports the nurse
by clarifying goals of care and mediating communication, not dictating decisions.
, 3. In developing a survivorship program for head and neck cancer patients,
what outcome metric best evaluates the longitudinal effectiveness of the CNS
intervention?
Answer: Change in patient reported quality of life scores (FACT H&N) and
reduction in unplanned acute care visits over 2 years.
Rationale: The AOCNS designs systems level outcomes. Patient reported
outcomes (PROs) capture the multidimensional impact (swallowing, pain,
psychosocial), which is the true measure of survivorship care quality.
4. You are analyzing a unit's central line associated bloodstream infection
(CLABSI) rates, which have spiked above the benchmark. Using the "Swiss Cheese
Model," what is the initial systems level approach?
Answer: Conduct a Root Cause Analysis (RCA) to identify latent failures and
active errors in the line insertion and maintenance processes.
Rationale: The Swiss Cheese model posits that adverse events result from
aligned failures across multiple barriers. The CNS focuses on system redesign
(standardization of kits, competency check offs, closed loop checklists).
5. A patient with non small cell lung cancer is starting immunotherapy. The
staff asks the CNS to differentiate between pseudo progression and true
progression. How is pseudo progression best defined?
Answer: An initial increase in tumor burden or appearance of new lesions
on imaging due to T cell infiltration, followed by a subsequent tumor regression
without changing therapy.
Rationale: The AOCNS educates staff and patients that checkpoint inhibitors
cause immune infiltration that mimics tumor growth. The iRECIST criteria are used
to confirm pseudo progression before declaring treatment failure.
, 6. A staff nurse makes a medication error with intrathecal Vincristine that was
inadvertently prepared in a syringe for intravenous use. As the CNS, what is the
most critical system redesign to prevent recurrence?
Answer: Mandate that Vincristine be diluted only in a mini bag (minibag
protocol) and never dispensed in a syringe, alongside forcing intrathecal agents to
be prepared and administered completely separately by trained, credentialed
staff.
Rationale: This is a fatal sentinel event. The CNS must lead a Failure Mode
and Effects Analysis (FMEA) to force the system to be "fail safe." Syringe
presentation of Vinca alkaloids is prohibited.
7. An AOCNS is evaluating a new biosimilar for supportive care (e.g., Filgrastim).
What is the primary regulatory distinction between a biosimilar and a generic
drug that must be communicated to the pharmacy committee?
Answer: A biosimilar is highly similar but not chemically identical to the
biologic reference product; it requires comparative efficacy and immunogenicity
data, unlike a generic which is bioequivalent and chemically identical.
Rationale: The CNS ensures that therapeutic interchange policies account
for the complexity of biologics and potential for immunogenicity, requiring
pharmacovigilance tracking.
8. What is the most appropriate validated tool for the AOCNS to screen for
cancer related cognitive impairment ("chemo brain") in the survivorship clinic?
Answer: The FACT Cog (Functional Assessment of Cancer Therapy
Cognitive Function), combined with a clinical interview and assessment for
reversible causes (depression, fatigue, sleep).
Rationale: The CNS utilizes multidimensional, validated PRO measures to
differentiate cognitive complaints from affective disorders and to guide cognitive
rehabilitation strategies.
, 9. A rural affiliate wants to initiate a "tele palliative care" service. According to
the Synergy Model, what is the CNS's primary contribution in matching the
remote patient's needs with nursing competencies?
Answer: Identify the unique patient characteristics (complexity, resource
availability, predictability) and ensure the tele health nurses have Level 3 5
competencies in virtual communication, symptom triage, and cultural empathy.
Rationale: The Synergy Model is a core CNS framework. The CNS assesses
the patient nurse interaction dynamic and up skills nurses to handle the
ambiguity and high stakes communication of remote palliative care.
10. A unit is adopting a new algorithm for managing immune related colitis.
Using the PARIHS framework (Promoting Action on Research Implementation in
Health Services), what is the "Context" factor that best predicts successful
implementation?
Answer: Transformational leadership support and a learning culture that
accepts practice change and provides feedback, rather than blaming staff for
previous severe colitis outcomes.
Rationale: The PARIHS framework states that Successful Implementation =
f(Evidence, Context, Facilitation). A receptive context with strong leadership
trumps weak evidence in a bad context.
11. A patient with chemo induced peripheral neuropathy (CIPN) has Grade 3
pain and functional decline. What non pharmacologic intervention does the
AOCNS recommend based on current ASCO guidelines?
Answer: Duloxetine (pharmacologic) is the only strong recommendation; for
non pharmacologic, exercise and acupuncture have moderate evidence for
symptom management.
Rationale: The CNS critically appraises guidelines. Gabapentin and tricyclic
antidepressants lack strong evidence for CIPN; the CNS ensures therapy aligns
with evidence, not anecdote.
