Care Technician Practice Questions & Detailed Rationales
2026/2027
Question 1
What is the correct clinical order of draw for venipuncture when
collecting multiple evacuated tubes (light blue, lavender, red, green)?
A. Lavender, light blue, red, green
B. Light blue, red, green, lavender
C. Red, light blue, green, lavender
D. Green, lavender, red, light blue
Correct Answer: B. Light blue, red, green, lavender
Detailed Rationale: Standard order of draw prevents cross-
contamination of tube additives (e.g., sodium citrate in light blue first,
followed by serum/red, heparin/green, and EDTA/lavender).
Question 2
Where is the V4 electrode placed when performing a standard 12-lead
electrocardiogram (ECG)?
A. Fourth intercostal space at the right sternal border
B. Fifth intercostal space at the left midclavicular line
C. Fourth intercostal space at the left sternal border
D. Fifth intercostal space at the left anterior axillary line
,Correct Answer: B. Fifth intercostal space at the left midclavicular line
Detailed Rationale: V4 placement is standard at the 5th intercostal
space in the midclavicular line. V1 is right sternal border, V2 is left
sternal border, V3 is halfway between V2 and V4, V5 is anterior axillary
line, and V6 is midaxillary line.
Question 3
What phase of the Korotkoff sounds represents the systolic blood
pressure measurement?
A. Phase I (the first appearance of faint, clear tapping sounds)
B. Phase III (crisp, loud knocking sounds)
C. Phase IV (muffling of sounds)
D. Phase V (complete disappearance of sounds)
Correct Answer: A. Phase I (the first appearance of faint, clear tapping
sounds)
Detailed Rationale: Systolic pressure corresponds to the initial onset of
tapping sounds (Phase I) as cuff pressure declines, while diastolic
pressure corresponds to the complete disappearance of sounds (Phase
V).
Question 4
According to CDC guidelines, what is the minimum recommended
duration for performing routine hand hygiene with soap and water?
A. 5 to 10 seconds
B. At least 20 seconds
,C. Exactly 2 minutes
D. 5 seconds
Correct Answer: B. At least 20 seconds
Detailed Rationale: Thorough handwashing with soap and water should
last for at least 20 seconds to effectively mechanically remove transient
microorganisms from skin surfaces.
Question 5
When assisting a patient with left-sided hemiparesis (weakness) to
transfer from a bed to a wheelchair, where should the wheelchair be
positioned?
A. On the patient's left side (weak side)
B. On the patient's right side (strong side)
C. Directly at the foot of the bed facing the headboard
D. Position does not matter
Correct Answer: B. On the patient's right side (strong side)
Detailed Rationale: The wheelchair should always be placed on the
patient's stronger side so the patient can lead with their strong side and
weight-bear safely during the pivot transfer.
Question 6
What immediate action should a patient care technician take if a patient
begins to experience syncope (fainting) during a venipuncture
procedure?
A. Continue drawing blood quickly to finish the test
, B. Remove the tourniquet and needle immediately, apply pressure, and
lower the patient's head or place them in a safe position
C. Walk the patient around the room immediately
D. Pour cold water on the patient's face
Correct Answer: B. Remove the tourniquet and needle immediately,
apply pressure, and lower the patient's head or place them in a safe
position
Detailed Rationale: Safety is paramount during fainting episodes; the
needle and tourniquet must be removed immediately to prevent injury,
followed by safe positioning and calling for medical assistance.
Question 7
What type of ECG artifact is characterized by erratic, jagged spikes and
baseline wander caused by patient movement, muscle tremor, or
shivering?
A. AC interference (60-cycle interference)
B. Somatic tremor artifact
C. Wandering baseline
D. Interrupted baseline
Correct Answer: B. Somatic tremor artifact
Detailed Rationale: Somatic tremor produces irregular, erratic baseline
fluctuations due to voluntary or involuntary muscle movement. AC
interference produces uniform small oscillations from electrical
equipment.
