1Under Missouri DHSS regulations, a Certified Nurse Assistant (CNA) training program must consist of at least how many hours of training?

A.50 hours

B.75 hours of classroom training and 100 hours of on-the-job training

C.120 hours

D.160 hours

Explanation: Missouri requires a state-approved CNA course to consist of 75 hours of classroom training and 100 hours of on-the-job training (total 175 hours). This is established under Section 198.082, RSMo, and the Omnibus Nursing Home Act. Some sources indicate minimum requirements of 75 classroom + 100 clinical hours, though specific program hours may vary.

2A Missouri CNA is preparing to take the competency examination. Who administers the CNA written and skills tests in Missouri?

A.Missouri State Board of Nursing

B.Prometric

C.Headmaster/D&S Diversified Technologies

D.Pearson VUE

Explanation: Missouri contracts with Headmaster/D&S Diversified Technologies (D&S) to administer the CNA competency examination. The exam consists of a written (or oral) test and a skills evaluation. Candidates can find information and schedule testing through the Headmaster TMU (Test Management Utility) system.

3A CNA in Missouri notices that a resident has developed a Stage 2 pressure injury. The CNA should:

A.Apply antibiotic ointment and cover with a sterile dressing

B.Document the finding and report it immediately to the nurse

C.Reposition the resident and monitor for 24 hours before reporting

D.Clean the wound with hydrogen peroxide and report at the end of the shift

Explanation: CNAs are responsible for observing and reporting changes in resident condition. A Stage 2 pressure injury (partial-thickness skin loss) must be reported to the nurse immediately. CNAs cannot treat wounds independently — that is outside their scope of practice. The nurse will assess the wound and obtain physician orders for treatment.

4Which of the following is within the scope of practice for a Missouri CNA?

A.Administering oral medications as directed by the nurse

B.Inserting a urinary catheter with supervision

C.Assisting with activities of daily living and reporting observations

D.Changing sterile wound dressings

Explanation: CNAs may assist with activities of daily living (ADLs) such as bathing, dressing, feeding, and toileting. They are also responsible for observing and reporting changes in resident condition. Administering medications, inserting catheters, and changing sterile dressings are outside the CNA scope of practice in Missouri and require licensed nursing intervention.

5A Missouri CNA is asked by a family member to explain the resident's diagnosis and treatment plan. The CNA should:

A.Provide a general explanation based on what the CNA has observed

B.Refer the family member to the nurse or physician

C.Show the family member the resident's chart

D.Explain the diagnosis but not the treatment plan

Explanation: Explaining diagnoses and treatment plans is outside the CNA's scope of practice. CNAs must refer family members to the nurse or physician for medical information. Additionally, HIPAA privacy regulations restrict who can access and discuss protected health information. Only authorized healthcare team members may discuss medical details with family.

6How often must a Missouri CNA renew their certification?

A.Every year

B.Every two years

C.Every three years

D.Certification does not expire in Missouri

Explanation: Missouri CNAs must renew their certification every two years. To renew, CNAs must provide documentation of at least 8 hours of paid employment performing nursing-related services under the supervision of a licensed nurse during the 24-month certification period. This employment requirement ensures competency is maintained through practice.

7A CNA who is certified in another state and in good standing wants to work in Missouri. What must they do?

A.Take the full Missouri CNA course and exam

B.Apply for reciprocity with Missouri

C.Work for 6 months before transferring certification

D.Take only the Missouri state law portion of the exam

Explanation: CNAs certified in another state who are in good standing can apply for reciprocity with Missouri. Once the application is approved, they can log into the Headmaster TMU system and print their Missouri CNA certificate. This process allows qualified CNAs from other states to work in Missouri without repeating the full training program.

8What is the primary purpose of the Missouri CNA competency examination?

A.To fulfill federal Medicare requirements

B.To demonstrate minimum knowledge and skills for safe patient care

C.To qualify for a nursing school admission

D.To meet insurance reimbursement standards

Explanation: The Missouri CNA competency examination (administered by Headmaster/D&S) is designed to ensure that nurse assistants demonstrate minimum knowledge and skills required to provide safe and effective patient care. The exam aligns with the Omnibus Nursing Home Act and federal OBRA requirements for nursing home staff competency.

9A Missouri CNA wants to "challenge" the CNA exam without taking the training course. According to Missouri regulations:

A.Anyone can challenge the exam without restrictions

B.Only those who meet specific challenge requirements can attempt it, with only one chance to pass

C.Challenging the exam is not allowed in Missouri

D.Nursing students can challenge after completing one clinical rotation

Explanation: Missouri allows certain individuals to challenge the CNA exam if they meet specific requirements. However, if a candidate fails the challenge exam, they must complete the full CNA course and pass both portions of the exam to become certified. This "one chance" policy emphasizes the importance of proper training.

10Which of the following best describes the CNA's role in the healthcare team?

A.The CNA works independently with minimal supervision

B.The CNA provides direct patient care under the supervision of a licensed nurse

C.The CNA supervises other CNAs and makes care decisions

D.The CNA manages the nursing unit in the absence of the nurse

Explanation: The CNA provides direct patient care (bathing, dressing, feeding, vital signs, etc.) under the supervision of a licensed nurse (LPN or RN). CNAs are essential members of the healthcare team but do not work independently, supervise other staff, or make independent clinical decisions. Their work is directed and overseen by licensed nursing staff.
