Iowa CNA Exam Flashcards

Q: What is the pass rate for the Iowa CNA exam?

The Iowa CNA exam has an estimated first-time pass rate of approximately 72%, based on Iowa DIAL data. The written portion requires 70% (49 of 70 questions correct) in 60 minutes, plus a satisfactory clinical skills evaluation. Both portions must be passed to be listed on the Iowa Direct Care Worker (DCW) Registry.

Q: Do I need to complete CNA training before taking the Iowa exam?

No — Iowa is the ONLY state that does not require completion of CNA training before testing. Candidates may take the competency exam first and complete the 75-hour training (45 didactic + 30 clinical, per Iowa Admin. Code 441 Ch. 81) afterward. Most employers and community colleges still recommend training first.

Q: Who administers the Iowa CNA exam?

The Iowa CNA written exam is administered by Headmaster / D&S Diversified Technologies through the TMU Iowa platform. Community colleges serve as proctor sites ($50), remote proctoring is available through Credentia ($70), and the clinical skills evaluation is scheduled through community colleges or Health Tech Associates ($115-$135). Iowa DIAL oversees the entire program.

Q: What is the Iowa Direct Care Worker (DCW) Registry?

Iowa uses the Direct Care Worker (DCW) Registry, not a traditional 'CNA Registry.' It is maintained by Iowa DIAL under Iowa Admin. Code 441 Ch. 81. Passing CNAs receive a six-digit registry ID number. The registry also permanently records substantiated findings of abuse, neglect, or misappropriation of resident property.

Q: How do I maintain my Iowa CNA certification?

To stay active on the DCW Registry, a CNA must complete at least 8 hours of qualifying paid work every 24 months and 12 hours of in-service training each calendar year (employer-paid if working in a state-licensed long-term care facility under Iowa Code Ch. 135C). Going 2 years without qualifying work requires retaking both competency tests.

Question 1

Normal adult vital sign ranges a CNA must recognize

Accepted Answer

Temperature: 97.6-99.6°F (oral). Pulse: 60-100 bpm. Respirations: 12-20 per minute. Blood pressure: 90-140 mmHg systolic over 60-90 mmHg diastolic. Any reading outside these ranges must be recorded and reported to the nurse immediately — never adjusted, repeated until 'normal,' or ignored.

Question 2

Counting a radial pulse: regular vs. irregular rhythm

Accepted Answer

For a regular pulse, count beats for 30 seconds and multiply by 2 (or 15 seconds x 4). For an irregular pulse, count for a full 60 seconds because irregular rhythms produce inconsistent intervals — a short count can produce a dangerously inaccurate rate. Report any irregular rhythm to the nurse.

Question 3

What counts as fluid for intake and output (I&O) measurement?

Accepted Answer

All beverages plus foods that are liquid at room temperature: soup, gelatin, ice cream, and pudding all count as intake. A common error is counting only drinks and overlooking liquid foods. Accurate I&O is critical for residents with cardiac, renal, or fluid-restriction orders.

Question 4

Minimum normal urinary output and when to report low output

Accepted Answer

Normal adult urinary output is approximately 30 mL per hour or more. Output below this must be reported to the nurse immediately, since it can signal dehydration, kidney dysfunction, or urinary obstruction. Catheter insertion, irrigation, and diuretics are outside the CNA scope of practice.

Question 5

Routine indwelling urinary catheter care a CNA performs

Accepted Answer

Clean the perineal area and 4 inches of catheter tubing closest to the meatus with soap and water at least once daily and after bowel movements, moving away from the body (not back and forth). Keep the drainage bag below bladder level and off the floor, and keep tubing free of kinks to prevent backflow and infection.

Question 6

Correct gait belt grip for a bed-to-wheelchair transfer

Accepted Answer

Grasp the center back of the gait belt with an underhand grip (palms up) for maximum control. Stand close with a wide stance and use leg muscles, not the back. Gripping the resident's arms, clothing, or belt loops instead of the gait belt is unsafe and can cause shoulder injury or falls.

Question 7

Early sign of a pressure injury a CNA must report immediately

Accepted Answer

Non-blanchable redness over a bony prominence (heels, sacrum, hips, elbows, shoulder blades) that does not fade within 30 minutes of pressure relief. Report immediately — do not massage reddened skin over a bony area, which can worsen tissue damage. Reposition at least every 2 hours to prevent progression.

Question 8

How often to reposition a resident at risk for pressure injuries

Accepted Answer

At least every 2 hours, following a written turning schedule, and more often if skin redness develops sooner. Use pillows and wedges to maintain alignment and offload pressure points. Report any skin changes to the nurse immediately.

Question 9

Minimum handwashing duration with soap and water

Accepted Answer

Scrub for at least 20 seconds — roughly the time to sing 'Happy Birthday' twice. Hand hygiene is the single most important infection-prevention measure. Alcohol-based hand rub is acceptable when hands are not visibly soiled, but soap and water is required when hands are visibly dirty or after C. diff or norovirus contact.

Question 10

Correct PPE donning (putting on) order

Accepted Answer

1) Gown, 2) Mask or respirator, 3) Goggles or face shield, 4) Gloves. The gown goes first to cover clothing, and gloves go last to cover the gown cuffs and provide a clean exterior layer.

Question 11

Correct PPE doffing (removal) order

Accepted Answer

1) Gloves, 2) Goggles or face shield, 3) Gown, 4) Mask or respirator. Perform hand hygiene after each step and immediately after all PPE is removed. Gloves come off first because they are the most contaminated; the mask is removed last to avoid touching the face with contaminated hands.

Question 12

Why alcohol-based hand rub fails against C. difficile

Accepted Answer

C. difficile produces spores that alcohol cannot kill. During a C. diff outbreak, soap-and-water handwashing for at least 20 seconds is required because mechanical friction and rinsing physically remove spores from the hands.

Question 13

Standard Precautions: when do they apply?

Accepted Answer

Standard Precautions apply to every resident, every time, regardless of known infection status — treat all blood, body fluids, secretions, excretions (except sweat), and non-intact skin as potentially infectious. This includes hand hygiene, appropriate PPE, and safe handling of sharps.

Question 14

Airborne precautions: which diseases and what PPE is required

Accepted Answer

Used for tuberculosis, measles, and varicella (chickenpox) — pathogens suspended in air that travel long distances. Requires a negative-pressure room and an N95 respirator (not a surgical mask), with the door kept closed. Droplet precautions (influenza, meningitis, pertussis) use a surgical mask and no negative pressure.

Question 15

PPE required for contact precautions (e.g., MRSA, C. diff, VRE)

Accepted Answer

Gloves and a gown are required when entering the room or having direct contact. An N95 respirator is not routinely required for contact precautions alone — that applies to airborne precautions. Remove gown and gloves before exiting the room, followed immediately by hand hygiene.

Question 16

RACE: fire emergency response sequence

Accepted Answer

R — Rescue residents in immediate danger. A — Activate the fire alarm. C — Contain the fire by closing doors and windows. E — Extinguish if trained and safe, or Evacuate. Rescue always comes first.

Question 17

PASS: fire extinguisher operation steps

Accepted Answer

P — Pull the pin. A — Aim at the base of the fire. S — Squeeze the handle. S — Sweep from side to side. RACE is the overall facility fire response protocol; PASS is specifically for operating the extinguisher.

Question 18

First priority when a resident is found on the floor after a fall

Accepted Answer

Do not move the resident. Call for the nurse immediately and stay with the resident, checking for obvious injury and providing reassurance. Moving an injured resident before assessment can cause further harm, such as worsening a fracture or spinal injury.

Question 19

Restraint monitoring requirements under OBRA regulations

Accepted Answer

Restrained residents must be released, repositioned, and offered toileting, exercise, and hydration at least every 2 hours, with circulation checked at each visit. Restraints require a physician's order and must be the least restrictive option after non-restraint measures fail. Four raised side rails also count as a restraint.

Question 20

Correct body mechanics for lifting a heavy object or repositioning a resident

Accepted Answer

Bend at the knees (not the waist), keep the back straight, and hold the object close to the body, using leg muscles to lift. Never twist the torso while lifting — twisting while bearing weight is a leading cause of back injury.

Question 21

Iowa CNA written exam format and passing score

Accepted Answer

Iowa's written exam has 70 multiple-choice questions completed in 60 minutes, requiring 49 correct (70%) to pass, plus a satisfactory clinical skills evaluation. Both portions must be passed to be listed on the Iowa Direct Care Worker Registry.

Question 22

Iowa's unique rule on training before testing

Accepted Answer

Iowa is the ONLY U.S. state that does not require completion of nurse aide training before sitting for the competency exam. Candidates may test first and complete the 75-hour training (45 didactic + 30 clinical, per Iowa Admin. Code 441 Ch. 81) afterward, though most employers recommend training first.

Question 23

Who administers the Iowa CNA competency exam?

Accepted Answer

Headmaster / D&S Diversified Technologies administers the written exam through the TMU Iowa platform, with community colleges serving as proctor sites and Credentia offering remote online proctoring. Clinical skills evaluations are scheduled through community colleges or Health Tech Associates. Iowa DIAL oversees the entire program.

Question 24

What is the Iowa Direct Care Worker (DCW) Registry?

Accepted Answer

Iowa's DCW Registry — not called a 'CNA Registry' — is maintained by Iowa DIAL under Iowa Admin. Code 441 Ch. 81. Passing CNAs are issued a six-digit registry ID number. The registry also permanently records substantiated findings of abuse, neglect, or misappropriation of resident property.

Question 25

DCW Registry renewal requirements for Iowa CNAs

Accepted Answer

To remain active on the DCW Registry, a CNA must complete at least 8 hours of qualifying paid nurse aide work every 24 months. If a CNA goes 2 years without qualifying work, both the written and skills competency tests must be retaken before returning to work in Iowa.

Question 26

Annual in-service training requirement for Iowa CNAs

Accepted Answer

Iowa CNAs working in a state-licensed long-term care facility must complete 12 hours of in-service training each calendar year, paid by the employer under Iowa Code Ch. 135C. In-service training keeps skills current and is separate from the 24-month DCW work requirement.

Question 27

Iowa CNA mandatory reporting chain for suspected abuse

Accepted Answer

Iowa CNAs are mandatory reporters under Iowa Code Ch. 235B. Suspected abuse, neglect, or exploitation must be reported immediately to the supervisor and to the Iowa Department of Health and Human Services (DHHS) Adult Protective Services. Delaying or failing to report is a violation of Iowa law.

Question 28

Role of the Iowa Long-Term Care Ombudsman (LTCOP)

Accepted Answer

The Iowa Long-Term Care Ombudsman Program, operating under Iowa DHHS, advocates for residents' rights and quality of life in nursing homes and assisted living. CNAs should refer residents and families to the ombudsman when facility-level complaints about care or rights violations cannot be resolved.

Question 29

Tasks within vs. outside the Iowa CNA scope of practice

Accepted Answer

Within scope: measuring/recording vital signs, assisting with ADLs, I&O measurement, routine indwelling catheter care, ROM, and reporting changes. Outside scope: inserting urinary catheters, sterile dressing changes, adjusting IV flow rates, administering medications, and performing nursing assessments.

Question 30

Correct method for fixing a charting error in a medical record

Accepted Answer

Draw a single line through the error so it remains legible, write 'error' beside it, initial and date the correction, then write the correct information. Never use correction fluid, erase, or destroy pages — these constitute falsification of a medical record, which is illegal.

Question 31

Residents' right to refuse care under OBRA and Iowa regulations

Accepted Answer

Residents have the right to refuse any care, including bathing. The CNA must respect the refusal, offer an alternative (partial bath, sponge bath), document the refusal, and report it to the nurse. Forcing care against a refusal is a violation of resident rights and can constitute abuse.

Question 32

HIPAA: when is disclosing resident health information permissible?

Accepted Answer

Protected health information (PHI) may be shared for treatment purposes among the care team, such as reporting a condition change to the nurse. Sharing with family without the resident's authorization, discussing residents where others can overhear, or posting photos on social media all violate HIPAA and resident privacy rights.

Question 33

Core protections in the federal Residents' Bill of Rights (OBRA 1987)

Accepted Answer

Includes the right to dignity and respect, privacy, freedom from abuse and unnecessary restraint, the right to refuse treatment, participation in one's own care planning, and the right to voice grievances without fear of retaliation. CNAs must uphold these rights in every interaction.

Question 34

Bed bath sequence: which body area is washed last and why

Accepted Answer

The perineal area is always washed last because it carries the highest bacterial concentration. The correct order moves from cleanest to dirtiest: face, neck, arms, chest, abdomen, legs, back, then perineal area, to prevent spreading bacteria and increasing infection risk.

Question 35

Dressing a resident with one-sided weakness (hemiplegia)

Accepted Answer

Always dress the affected (weaker) side first and undress the stronger side first. Dressing the weak side first minimizes the range of motion required. Memory rule: 'dress the weak side first, undress the strong side first.'

Question 36

Positioning an unconscious resident for oral care

Accepted Answer

Position supine with the head turned to the side so gravity drains fluid out of the mouth, reducing aspiration risk. Use a small amount of fluid, swabs instead of a toothbrush, and suction if available.

Question 37

Correct shaving direction with a safety razor

Accepted Answer

Shave in the direction of hair growth (typically downward on the face). Shaving against the grain increases the risk of skin irritation, ingrown hairs, and nicks. For residents on anticoagulants, use an electric razor instead to reduce bleeding risk.

Question 38

When to apply elastic compression stockings (TED hose)

Accepted Answer

Apply while the resident is lying down and before they stand up. Once upright, blood pools in the lower extremities and legs swell, making proper fit impossible. Skin must be dry and stockings smooth with no wrinkles — wrinkles create pressure points that can cause skin breakdown.

Question 39

Assisting a visually impaired resident with eating

Accepted Answer

Use the clock method to describe food placement (e.g., 'meat at 6 o'clock, vegetables at 3 o'clock') and allow maximum independence. Position the resident upright (at least 45-90 degrees). Never feed a resident who is able to self-feed — doing so removes autonomy and dignity.

Question 40

Precautions when feeding a resident with dysphagia (swallowing difficulty)

Accepted Answer

Position the resident fully upright (90 degrees), offer small bites, and use thickened liquids as ordered — thin liquids are more likely to be aspirated. Keep the resident upright for at least 30 minutes after eating. Report coughing, choking, or pocketing food to the nurse immediately.

Question 41

Validation therapy for a dementia resident asking about a deceased spouse

Accepted Answer

Acknowledge the emotion and redirect to a comforting activity rather than repeatedly correcting with facts. Repeatedly informing a dementia resident of a death causes fresh grief each time without improving orientation. Example: 'You miss your husband; he sounds very special to you.'

Question 42

Behavioral signs most consistent with clinical depression in a long-term care resident

Accepted Answer

Persistent sadness, withdrawal from social interaction, loss of interest in previously enjoyed activities (anhedonia), and changes in sleep and appetite. Confusion about time/place is more characteristic of dementia; report depression signs for medical evaluation.

Question 43

Communicating with a resident who is hard of hearing

Accepted Answer

Face the resident directly so they can see lip movement and facial expressions, speak at a normal volume with clear enunciation, and ensure adequate lighting. Shouting distorts the voice and is demeaning; a lower-pitched voice is easier to hear.

Question 44

Sundowning in dementia residents: what it is and how to respond

Accepted Answer

Sundowning is increased confusion, agitation, or restlessness in the late afternoon or evening, common in dementia. Reduce triggers with a calm environment, adequate lighting, minimal noise, and a consistent routine. Report patterns to the nurse; never respond with confrontation or restraints.

Question 45

First action when a resident expresses hopelessness or suicidal thoughts

Accepted Answer

Report to the nurse immediately and do not leave the resident alone. The CNA's role is not to conduct a risk assessment — that is the nurse's or social worker's job. Getting the nurse involved immediately is always the correct first action.

Question 46

What to do when resistance or pain occurs during passive range of motion

Accepted Answer

Stop the movement immediately, support the joint in a comfortable position, and report to the nurse. Never force ROM past resistance — doing so can cause fractures, dislocations, or tissue damage, especially in frail elderly residents.

Question 47

Contracture prevention: how a CNA helps prevent permanent joint shortening

Accepted Answer

Perform regular passive and active range-of-motion exercises, position residents with proper alignment and support pillows, apply splints or orthotics as ordered, and reposition at least every 2 hours. Contractures develop when a joint stays immobile for a prolonged period and the muscles shorten and freeze it in place — once established, they are difficult to reverse.

Question 48

Purpose of a restorative dining program

Accepted Answer

A restorative dining program helps residents maintain or regain independent eating skills through adapted utensils, proper positioning, and encouragement rather than the CNA taking over the task. It is distinct from routine feeding assistance because the goal is preserving the resident's own function, not simply completing the meal quickly.

Question 49

Primary goal of a restorative nursing program

Accepted Answer

Maintain the resident's current functional abilities and prevent further decline — not to restore pre-illness function (that is rehabilitation's goal). CNAs support restorative programs through ROM, ambulation assistance, and encouraging independence during daily ADL care.

Question 50

Respecting spiritual and cultural needs in resident care

Accepted Answer

Accommodate dietary restrictions, prayer schedules, and modesty preferences tied to a resident's faith or culture, and refer to chaplain or spiritual services on request. Advance directives (living wills, durable power of attorney for health care) are governed in Iowa by Iowa Code Ch. 144A and must be honored as documented in the care plan.
