Correct answer: A. 1:15

Correct. 19 CSR 30-84.010(11) sets the maximum instructor and clinical supervisor/student ratio at one to fifteen (1:15) during the 100 hours of supervised on-the-job training.

• B: 1:5 is stricter than what Missouri's rule requires; the actual maximum allowed is 1:15.
• C: 1:25 exceeds the maximum ratio Missouri permits; supervision above 1:15 would violate the rule.
• D: 1:10 is not the ratio specified in 19 CSR 30-84.010(11); the rule sets it at 1:15.

Correct answer: A. The thumb side of the wrist

Correct. The radial pulse is palpated on the thumb side of the wrist, over the radial artery, and is the standard site nursing assistants use for routine pulse counts.

• B: The neck location describes the carotid pulse, not the radial pulse.
• C: Behind the knee describes the popliteal pulse site, not the radial pulse.
• D: The top of the foot describes the dorsalis pedis pulse site, not the radial pulse.

Correct answer: A. 75 hours instructional training plus 100 hours supervised on-the-job training (175 total)

Correct. 19 CSR 30-84.010(4)(A)-(B) requires a basic course of seventy-five (75) hours of instructional training and one hundred (100) hours of supervised on-the-job training, for 175 total hours.

• B: This understates both components; Missouri's rule sets the minimums at 75 and 100 hours, not 40 and 60.
• C: Missouri's rule explicitly requires a separate 100-hour supervised on-the-job (clinical) component; classroom hours alone are not sufficient.
• D: The on-the-job training requirement is 100 hours, not 75; the two components are not equal in Missouri's rule.

Correct answer: A. 16 hours

Correct. 19 CSR 30-84.010(4)(D) requires that prior to direct contact with a resident, a student complete sixteen (16) of the required 75 instructional hours covering communication/interpersonal skills, infection control, safety/emergency procedures (including the Heimlich maneuver), promoting residents' independence, and respecting residents' rights.

• B: 75 hours is the full instructional-hour requirement for the entire basic course, not the pre-contact minimum.
• C: 4 hours is the length of Missouri's instructor update training requirement, not the pre-resident-contact training minimum.
• D: 40 hours is not a figure used in this rule; it does not match the 16-hour pre-contact requirement.

Correct answer: A. The Employee Disqualification List (EDL)

Correct. 19 CSR 30-84.010(6)(A)1. requires that, to be eligible to enroll, the individual not be listed on the department's Employee Disqualification List (EDL) and not have certain disqualifying criminal convictions.

• B: The Nurse Aide Registry is where certified nursing assistants are listed after passing; being listed there is a goal of training, not a bar to enrollment.
• C: The Family Care Safety Registry is Missouri's background-screening registry for people caring for children, elderly, or disabled persons in other contexts; it is not the enrollment disqualification list named in this rule.
• D: The certifying agency roster tracks approved certifying agencies and instructors, not individual student eligibility.
