Q1What is the accepted normal resting adult heart rate range?
Show answer
✓ Correct answer: 60-100 beats per minute
A normal resting adult pulse is 60-100 beats per minute. Below 60 is bradycardia and above 100 is tachycardia.
Q2Which value represents a normal adult resting respiratory rate?
Show answer
✓ Correct answer: 12-20 breaths per minute
Normal adult respiration is about 12-20 breaths per minute; newborns breathe much faster.
Q3On a blood pressure reading, the systolic value represents pressure during which cardiac event?
Show answer
✓ Correct answer: Ventricular contraction
Systolic pressure (the higher number) is measured during ventricular contraction, when blood is ejected into the arteries.
Q4Which action is the single most effective means of preventing the spread of infection in health care?
Show answer
✓ Correct answer: Proper hand hygiene
Hand hygiene (washing or alcohol-based rub) is recognized by the CDC as the most effective single measure to reduce health-care-associated infection.
Q5A sterile field is considered contaminated if which of the following occurs?
Show answer
✓ Correct answer: Any portion of the drape extends below table level
Any part of a sterile drape below table level is considered unsterile because it cannot be monitored; sterile fields must be kept above waist or table height and in view.
Q6Airborne precautions, such as for active tuberculosis, require which respiratory protection for the technologist?
Show answer
✓ Correct answer: A fitted N95 respirator
Airborne pathogens such as tuberculosis travel on small droplet nuclei, so a fit-tested N95 (or higher) respirator is required, not a surgical mask.
Q7A patient with Clostridioides difficile requires which specific hand-hygiene measure?
Show answer
✓ Correct answer: Soap-and-water washing because alcohol does not kill the spores
C. difficile forms spores that alcohol-based rubs do not kill; mechanical removal by washing with soap and water is required.
Q8When lifting a heavy object, the technologist should primarily use which muscle group?
Show answer
✓ Correct answer: The leg muscles by bending the knees
Proper body mechanics direct the lifter to bend at the knees and lift with the legs, keeping the back straight to avoid spinal injury.
Q9When transferring a patient from a wheelchair to the table, the wheelchair should be positioned how?
Show answer
✓ Correct answer: Parallel to the table with brakes locked
The chair is placed parallel to the table with wheels locked and footrests up so the patient pivots safely over the shortest distance.
Q10A nasal cannula typically delivers oxygen at what flow rate range?
Show answer
✓ Correct answer: 1-6 liters per minute
A nasal cannula is a low-flow device delivering roughly 1-6 L/min; higher rates dry the mucosa and a mask is used instead.
