Exam Structure:
Subject: Patient Care Assistant (PCA) Fundamentals
Source: PCA Exam Questions – Verified Answers
Format: Multiple Choice & Open-Ended Q&A
1. Report vital sign measurements immediately to the nurse if they are
abnormally ______ or ______.
Correct Answer: High / Low
Rationale:
1. Abnormal vital signs (high or low) can indicate patient deterioration.
2. Examples: hypertension, hypotension, tachycardia, bradycardia, fever,
hypothermia.
3. PCAs are responsible for recognizing and reporting deviations from normal
ranges.
4. Timely reporting allows nurses to initiate appropriate interventions.
2. Besides the rate when taking a pulse, what do you need to be aware
of?
Correct Answer: Rhythm and Quality
Rationale:
1. Rhythm refers to regularity of beats (regular vs. irregular).
2. Quality describes pulse strength (weak, thready, bounding, strong).
3. Irregular rhythm may indicate arrhythmias (e.g., atrial fibrillation).
4. Changes in quality can signal dehydration, shock, or heart failure.

3. List six reasons a patient may be at risk to fall.
Correct Answer: History of a fall, age over 65, taking 3-4 medications
daily, problems with bladder or bowel, poor mobility, sensory impairment,
male gender.
Rationale:
1. Prior fall history is the strongest predictor of future falls.
2. Age >65 increases risk due to frailty, balance, and vision changes.
3. Multiple medications (polypharmacy) cause dizziness and orthostatic
hypotension.
4. Bladder/bowel urgency leads to rushing to bathroom (number one
cause of falls).
5. Poor mobility and sensory impairment (vision, hearing) reduce ability to
navigate safely.
4. What is the number one reason patients fall?
Correct Answer: They need to use the restroom.
Rationale:
1. Urgency to void or defecate causes patients to rush without calling for help.
2. They may attempt to get up independently despite mobility limitations.
3. Prevention: scheduled toileting, bedpan/urinal within reach, call light
answered promptly.
4. Falls are often unwitnessed and occur in the bathroom or en route.
5. What agency issues the standards regarding the use of restraints?
Correct Answer: The Joint Commission and CMS (Centers for Medicare &
Medicaid Services).
Rationale:
1. The Joint Commission sets accreditation standards for restraint use in
hospitals.
2. CMS regulates restraints in nursing homes and Medicare/Medicaid
facilities.
3. Standards require physician order, frequent monitoring, and least
restrictive methods first.
4. Restraint use is strictly limited to prevent harm to patient or others.
6. Name a reason a patient may need to be restrained.
Correct Answer: If they are at risk for harming themselves or others.

Rationale:
1. Behavioral restraints: agitation, confusion, pulling at tubes, hitting staff.
2. Medical restraints: prevent removal of life-sustaining devices (ventilator,
IV lines).
3. Restraints are a last resort after less restrictive measures fail.
4. Requires ongoing assessment and documentation.
7. Pneumonia, urine retention/constipation, and sensory deprivation
can be caused by long periods of what?
Correct Answer: Immobility
Rationale:
1. Immobility leads to hypostatic pneumonia (pooled secretions in lungs).
2. Urine retention and constipation result from decreased muscle tone and
positioning.
3. Sensory deprivation occurs from lack of environmental stimulation.
4. Other complications: pressure ulcers, contractures, DVT, muscle atrophy.
8. What can you as a PCA do to prevent pressure ulcers on a restrained
patient?
Correct Answer: Reposition the patient every 2 hours; massage or pad
bony area prominences and other vulnerable areas.
Rationale:
1. Repositioning relieves pressure on vulnerable areas (sacrum, heels, elbows).
2. Padding reduces friction and shear forces.
3. Massage (gentle) around bony prominences improves circulation (avoid
over red areas).
4. Restrained patients cannot reposition themselves, so PCA assistance is
critical.
9. What is a communicable disease?
Correct Answer: An infection that can be passed from one person to
another.
Rationale:
1. Transmission occurs via direct contact, droplets, airborne, or contaminated
surfaces.
2. Examples: influenza, COVID-19, tuberculosis, norovirus, C. diff.
