California CNA (Certified Nursing Assistant)

The accepted adult normal range for blood pressure is approximately:

1. ASystolic 140-180 mmHg and diastolic 90-120 mmHg
2. BSystolic 180-200 mmHg and diastolic 100-120 mmHg
3. CSystolic 90-120 mmHg and diastolic 60-80 mmHgCorrect
4. DSystolic 60-90 mmHg and diastolic 40-60 mmHg

Why: Normal adult resting BP is roughly systolic 90-120 and diastolic 60-80 mmHg, per AHA fundamentals. Below 90/60 may indicate hypotension and risk of falls or hypoperfusion; readings of 130/80 or above are stage 1 hypertension per the 2017 AHA/ACC guidelines, and a reading at or above 180/120 with symptoms is hypertensive crisis requiring urgent evaluation. CNAs measure accurately and report findings outside the resident's set parameters to the nurse promptly so timely intervention can occur.ANA fundamentals of nursing; AHA BP guidelines

Which of the following is OUTSIDE a California CNA's scope of practice?

1. AAssisting a resident with bathing, toileting, ambulation, and feeding at mealtimes
2. BReporting changes in a resident's condition to the licensed nurse and charting them
3. CAdministering an injectable medication or performing initial nursing assessmentCorrect
4. DMeasuring and recording vital signs, intake and output, and the resident's weight

Why: Under HSC §1337-1338 and Title 22 CCR §71835, a California CNA performs basic nursing services under the supervision of a licensed nurse: ADLs, vital signs, intake/output, ambulation, observation, and reporting. CNAs DO NOT administer injectable or oral medications (a Certified Medication Aide/CMA is a separate credential), do not perform sterile procedures, do not insert/remove catheters except as specifically delegated, do not perform initial admission nursing assessments, and do not give telephone/verbal orders. Working outside scope is grounds for CDPH discipline, civil liability, and possibly criminal practice without a license.HSC §1337; HSC §1338; Title 22 CCR §71835
