- Domain 1, Care Continuum, is the smallest CPHON domain at just 6% of the 165-item exam.
- Even at 6%, it still contributes roughly 7-10 scored questions on diagnosis-to-survivorship transitions.
- Content spans discharge planning, survivorship care plans, palliative/hospice transitions, and pediatric-to-adult handoffs.
- All CPHON questions are four-option, one-best-answer, generic-drug-name items with no scheduled breaks.
What Domain 1 Covers on the CPHON Exam
Domain 1, Care Continuum, accounts for only 6% of the CPHON exam blueprint, making it the smallest of the six content areas. Out of 125 scored questions, that translates to roughly seven to ten items - a modest slice, but one that candidates frequently underestimate because its content feels "soft" compared to chemotherapy protocols or oncologic emergencies.
In practice, Domain 1 tests whether a pediatric hematology/oncology nurse understands how a child and family move through the entire arc of care - from initial diagnosis, through active treatment, into survivorship, relapse, or end-of-life care - and how the nurse coordinates services, providers, and settings along the way. It is less about a single disease process and more about systems, transitions, and continuity.
If you haven't already reviewed how this domain fits into the full blueprint, the CPHON Exam Domains 2026: Complete Guide to All 6 Content Areas breaks down all six areas side by side, which is a useful companion to this deeper dive into Domain 1 specifically.
Core Care Continuum Topics You Must Master
Because Domain 1 is compact, ONCC tends to test a focused set of recurring concepts rather than obscure edge cases. Expect questions built around these themes:
Diagnosis-to-Treatment Transition
Candidates must know how newly diagnosed pediatric hematology/oncology patients and families are onboarded into care, including initial education, consent processes, and the nurse's role in coordinating the first treatment plan.
- Role of the nurse navigator or care coordinator at diagnosis
- Family education needs during the "shock" phase of a new diagnosis
- Coordination between inpatient, outpatient, and specialty services
Survivorship Care Planning
As more pediatric hematology/oncology patients move into long-term survivorship, nurses must understand what a survivorship care plan contains and when it is initiated.
- Treatment summary documentation for late-effects screening
- Risk-based follow-up schedules tied to prior therapy exposure
- Transition planning from pediatric to adult survivorship clinics
Palliative, Hospice, and End-of-Life Transitions
Care Continuum content overlaps with, but is distinct from, the psychosocial content tested elsewhere. Here the focus is on the logistics and timing of shifting a patient's goals of care.
- Differentiating palliative care integration from hospice referral
- Recognizing appropriate triggers for a goals-of-care conversation
- Coordinating home-based, hospital-based, and community-based end-of-life services
Care Coordination Across Settings
Expect scenario-based items about handoffs between inpatient units, outpatient clinics, home health, school, and primary care.
- Discharge planning and readiness criteria
- Communication tools used across interdisciplinary teams
- Community resource referral (financial, transportation, housing)
For a broader look at how this content links to disease-specific nursing practice, see the companion guide on CPHON Domain 2: Pediatric Hematology and Oncology Nursing Practice (18%) - Complete Study Guide 2026, since many continuum-of-care scenarios are built on top of specific diagnoses covered there.
How Domain 1 Questions Are Written
Every item on the CPHON exam, including Domain 1 questions, follows the same four-option, one-best-answer multiple-choice format. There is no partial credit and no "select all that apply" style item - you are choosing the single best response from four plausible-sounding options.
Domain 1 questions tend to be scenario-driven rather than fact-recall. A typical stem describes a patient at a specific point in the care trajectory - newly diagnosed, mid-treatment, entering survivorship, or transitioning to palliative care - and asks what the nurse should do next, or which team member should be involved. Because the domain is small, ONCC generally avoids highly technical or drug-specific content here; that level of detail is reserved for domains like Treatment Modalities and Side Effects.
Key Takeaway
Read Domain 1 stems for the "phase of care" clue word - diagnosis, active treatment, survivorship, relapse, or end-of-life - since the correct answer usually depends on where the patient sits in that continuum.
All items use generic drug names, which matters even in a domain that isn't primarily pharmacology-focused - a question about coordinating a maintenance therapy transition, for example, will reference the generic agent name rather than a brand name.
Domain 1 in Context: How It Fits with the Other Five Domains
Domain 1 is the lightest-weighted content area on the exam. Seeing it next to the other five domains helps calibrate how much study time it deserves relative to everything else.
| Domain | Weight | Relative Study Priority |
|---|---|---|
| Domain 1: Care Continuum | 6% | Lowest - review once, focus on transitions |
| Domain 2: Pediatric Hematology and Oncology Nursing Practice | 18% | High - disease-specific foundation |
| Domain 3: Treatment Modalities and Side Effects | 21% | Very high - chemo, biotherapy, HSCT, radiation |
| Domain 4: Symptom Management and Supportive Care | 26% | Highest - largest domain on the exam |
| Domain 5: Pediatric Hematologic and Oncologic Emergencies | 21% | Very high - time-sensitive recognition and response |
| Domain 6: Psychosocial Dimensions of Care | 8% | Low-moderate - family, developmental, and coping content |
Notice that Domains 1 and 6 together only make up 14% of the exam, while Domains 3, 4, and 5 combine for 68%. That doesn't mean you should skip Care Continuum content - it means you should study it efficiently and move on. For a full breakdown of the largest domain, Symptom Management and Supportive Care, see CPHON Domain 4: Symptom Management and Supportive Care (26%) - Complete Study Guide 2026, and for the treatment-heavy domain, review CPHON Domain 3: Treatment Modalities and Side Effects (21%) - Complete Study Guide 2026.
If you're still deciding how much total prep time to budget across all six domains, the CPHON Study Guide 2026: How to Pass on Your First Attempt lays out a full-exam approach that places Domain 1 appropriately within the bigger picture.
Who Hires CPHONs and Why Care Continuum Knowledge Matters
Care Continuum competency isn't just an exam requirement - it reflects real responsibilities in pediatric hematology/oncology roles. Nurses in inpatient oncology units, ambulatory infusion centers, stem cell transplant programs, and survivorship clinics are all expected to coordinate handoffs as patients move between phases of care. Case managers, nurse navigators, and clinical nurse specialists in children's hospitals lean especially heavily on this competency.
Employers that recruit CPHON-certified nurses value this domain because poor care transitions - a missed survivorship referral, an unclear discharge plan, a delayed palliative care conversation - directly affect patient outcomes and family experience. If you're curious about where CPHON credentials open doors, CPHON Jobs covers the settings and roles that typically list the certification as preferred or required, and CPHON Salary Guide 2026: Complete Earnings Analysis looks at how certification factors into compensation conversations.
Scheduling Domain 1 Into Your Study Plan
Because Domain 1 is small, it doesn't need its own multi-week study block. The most efficient approach is to fold it into the same week you review psychosocial content (Domain 6) or early disease-process material (Domain 2), since continuum-of-care scenarios frequently intersect with family communication and diagnosis-specific pathways.
Foundational Disease Review + Care Continuum Overview
- Read through Domain 2 disease processes
- Layer in Domain 1 concepts: diagnosis onboarding, discharge readiness
- Create a one-page reference on survivorship care plan components
Heavy Domains: Treatment Modalities, Symptom Management, Emergencies
- Prioritize Domains 3, 4, and 5 - they make up 68% of the exam
- Revisit Domain 1 only through mixed practice questions
Psychosocial + Care Continuum Consolidation
- Pair Domain 6 psychosocial content with Domain 1 transitions
- Run timed practice sets combining all six domains in proportion to their weights
Practicing full-length, mixed-domain question sets on our CPHON practice test platform is one of the fastest ways to confirm that low-weight domains like Care Continuum haven't slipped through the cracks, since they're easy to under-review in a study plan dominated by chemotherapy and emergency content.
Registration and Exam-Day Mechanics to Know Before You Sit
Domain content aside, it helps to understand the mechanics surrounding the exam itself, since Care Continuum questions are woven into the same 165-item, single test session as everything else. The CPHON exam is administered by the Oncology Nursing Certification Corporation (ONCC) through PSI test centers. Candidates answer 165 four-option, one-best-answer questions - 125 scored and 40 unscored pretest items, mixed together so you won't know which is which - within a three-hour session that also includes a 15-minute tutorial and a post-test survey. There are no scheduled breaks built into that window.
A passing result requires a scaled score of 55 on a 25-75 scale. Eligibility requires an active, unencumbered RN license (U.S., territorial, or Canadian), two years of RN experience within the preceding four years, 2,000 hours of pediatric hematology/oncology nursing practice within the preceding four years, and 10 contact hours of oncology or hematology nursing continuing education (or an academic elective) within the preceding three years, with no more than five of those hours coming from CME or CPE.
The exam fee is $300 for members of the Oncology Nursing Society or the Association of Pediatric Hematology/Oncology Nurses, and $420 for nonmembers. Once approved, candidates receive a 90-day PSI testing window to schedule and sit for the exam. Full pricing detail, including what's included and how membership discounts work, is covered in CPHON Certification Cost 2026: Complete Pricing Breakdown.

Frequently Asked Questions
Domain 1 makes up 6% of the 125 scored questions on the CPHON exam, which works out to roughly seven to ten scored items, plus a small number of unscored pretest questions mixed into the same 165-item test.
It focuses on how patients and families move through diagnosis, active treatment, survivorship, relapse, and end-of-life care, along with the nurse's role in coordinating handoffs, discharge planning, survivorship care plans, and palliative or hospice transitions.
A light review is enough for most candidates. Since Domain 1 is only 6% of the exam, it's most efficient to fold it into study sessions covering disease-specific practice or psychosocial content rather than dedicating separate weeks to it.
They aren't necessarily harder, just different in style. Rather than testing drug doses or lab values, Domain 1 questions typically ask what the nurse should do next given a patient's phase of care, so understanding the sequence of the care continuum matters more than memorizing details.
Mixed-domain practice exams that reflect the real 165-question, four-option format are the best preparation. You can build familiarity with this question style, including Care Continuum scenarios, through the practice tests available on our CPHON practice test platform.
