- CNA written: there is usually no penalty for guessing; answer every item before time expires.
- CHPN: computer-based delivery at a testing center or remote proctor per HPCC policies.
- Report to your registry or certifying body if you need accommodations; request them before scheduling.
Study strategies
- Pair practice quizzes with skills lab or clinical hours for CNA candidates.
- For CHPN, review HPCC’s detailed content outline and mark weak domains after each practice set.
- Keep a mistake log by topic (infection control, opioids, ethics) and review it weekly.
- Read rationales fully—they teach patterns that repeat across vendors and item banks.

- Studying a national outline when your state tests different reporting rules.
- Memorizing skill steps without practicing them physically for the CNA demonstration.
- Choosing aggressive treatment options on CHPN items when comfort and goals of care point elsewhere.
- Cramming the night before instead of short daily practice with rationales.
