BSN206 Quiz 4 Safety, Body Mechanics, and Patient Mobility (Module 4 50 questions and
correct answers with rationales)
covers evidence-based injury prevention, safe patient handling, fall mitigation, and restraint
protocols.
1. Which muscle group should the nurse primarily utilize to lift a heavy object off the floor
safely?
A) Back and lumbar paraspinous matrix
B) Gluteal and quadriceps muscle groups in the legs
C) Intercostal and abdominal muscle fibers
D) Deltoid and bicep upper arm groups
Rationale: Utilizing the large, strong muscle groups of the thighs and buttocks prevents
lumbar strain and optimizes mechanical lift efficiency.
1. A nurse is preparing to reposition a dependent patient up in bed. What is the first
mechanical step to protect the nurse's spine?
A) Pulling the patient without assistance using a quick jerk motion
B) Adjusting the bed height to a comfortable working level near the nurse's waist
C) Dropping the side rails down on both sides simultaneously
D) Locking the bed wheels after the shift ends
Rationale: Bringing the bed to waist level eliminates excessive trunk flexion and reduces
shear stress on the nurse’s lumbar discs.
1. To maintain a broad and stable base of support when lifting or transferring a client, the
nurse should place their feet:
A) Together with heels touching closely
B) Shoulder-width apart with one foot slightly forward
C) Cross-legged to anchor balancing points
D) On the tips of the toes to maximize reach
Rationale: A wide stance lowers the center of gravity and increases lateral stability,
which helps prevent falls or muscle strains.
1. An older adult patient is scored at a high risk for falls using the Morse Fall Scale. Which
intervention is appropriate?
A) Keeping all four side rails elevated at all times
B) Placing a fall risk wristband on the patient and activating a bed exit alarm
C) Dimming the room lights completely so the patient sleeps constantly
D) Restricting oral fluid intake to avoid nighttime urination needs
Rationale: Visual fall-risk identifiers and electronic bed sensors alert staff promptly to
movement, allowing for timely intervention without applying physical restraints.
, 1. A confused patient continuously attempts to pull out an essential central venous catheter.
Less restrictive measures have failed. What type of device requires a licensed provider's
order before application?
A) Standard soft hospital gown lines
B) Soft wrist restraints
C) An automated electronic blood pressure cuff
D) A continuous pulse oximetry sensor
Rationale: Wrist restraints restrict freedom of movement and are legally classified as
physical restraints, which require a provider's prescription and strict monitoring.
1. Under emergency conditions to protect a patient from immediate self-harm, a nurse
applies a restraint. How soon must a face-to-face provider assessment occur?
A) Within 12 hours
B) Within 24 hours
C) Within 1 hour
D) At the next scheduled monthly meeting
Rationale: Joint Commission and CMS guidelines state that following emergency
restraint application, a provider must evaluate the patient face-to-face within 60 minutes.
1. A restraint order for an adult patient can be legally renewed for a maximum consecutive
duration of:
A) 30 minutes
B) 1 hour
C) 4 hours
D) 24 hours
Rationale: Behavioral or medical management restraint prescriptions for adults are valid
for a maximum of 4 hours before requiring re-evaluation and renewal.
1. When securing a soft wrist restraint to a patient's bed, the nurse must tie the strap to
which structure?
A) The movable side rails
B) The footboard slats
C) The movable bed frame that moves with the mattress
D) The wall suction console unit
Rationale: Securing restraints to a movable section of the frame ensures that adjusting the
bed head or foot does not inadvertently tighten or loosen the strap, which minimizes the
risk of injury.
1. Which knot type must always be used when securing a physical restraint to guarantee
quick release during an emergency?
A) Double square knot
