Hardest CHPN Practice Questions — Can You Answer These?

PPS 20%. Rationale: Bedbound, Total Care, Minimal Sips, and Confusion/Drowsy all align with PPS 20%. Exam Tip: To distinguish 20% from 10%, look at intake and LOC. PPS 20% involves Minimal Sips and Confusion/Drowsy, whereas PPS 10% involves Mouth care only and Coma. Both require Total Care and are Bedbound.

PPS 60%. Rationale: The patient is Ambulatory, but the presence of Occasional Assistance for self-care and being Unable to do any work/hobby confirms 60%. Exam Tip: Distinguish 60% from 50% by looking at Ambulation. At 60%, they are still Ambulatory (can walk). At 50%, they are Mainly Sit/Lie. Assistance at 60% is usually for more complex tasks (bathing/dressing), whereas 70% is completely independent.

PPS 30%. Rationale: Despite being Full in the Level of Consciousness (LOC) column, the patient is Bedbound and requires Total Care, which anchors the score at 30%. Rationale: The leftmost columns (Ambulation and Self-Care) carry more weight in the calculation than the rightmost (LOC). In neurodegenerative diseases like ALS, LOC often remains Full even when the PPS is 30% or 20%.

PPS 50%. Rationale: According to the PPS v2 tool, 60% is defined as Significant disease and Reduced activity. The transition to Extensive disease and Unable to do any work occurs at the 50% level. This is a high-yield exam fact because it marks the transition to a more advanced disease state where the focus shifts heavily toward palliative symptom management and away from functional maintenance.

The rapid decline (20% drop in 1 month) is a strong prognostic indicator of shortened survival and suggests the need for a hospice eligibility reassessment. Rationale: While single PPS scores are helpful, the velocity of decline is more predictive of mortality. A drop to 40% or below is statistically associated with a higher risk of death within weeks. HPCC focuses on the nurse's role in identifying these trends to facilitate timely goals-of-care conversations and hospice referrals.
