NR 224 Fundamentals of Nursing Exam 9 Study Guide 2026
|Chamberlain College
1. When lifting a heavy object, which action by the nurse demonstrates proper
body mechanics?
A. Keeping the feet close together
B. Bending at the waist to reach the object
C. Lifting with the back muscles while twisting
D. Flexing the knees and hips
Answer: D
Rationale: Flexing the knees and hips shifts the workload to the large muscles of the legs
and maintains the center of gravity, preventing back strain.
2. A nurse is preparing to transfer a patient with left-sided weakness from the
bed to a chair. Where should the chair be placed?
A. On the patient’s left side
B. On the patient’s right side
C. At the foot of the bed
D. Directly in front of the patient
Answer: B
Rationale: The chair should be placed on the patient’s stronger side (the right side in this
case) to allow the patient to lead with their strong leg during the transfer.
,3. Which assessment finding is a primary indicator of orthostatic hypotension
when moving a patient from supine to standing?
A. An increase in heart rate by 5 beats per minute
B. A decrease in systolic blood pressure by 20 mmHg
C. A decrease in diastolic blood pressure by 5 mmHg
D. The patient reporting feeling energetic
Answer: B
Rationale: Orthostatic hypotension is defined as a drop in systolic pressure of at least 20
mmHg or a drop in diastolic pressure of at least 10 mmHg within 3 minutes of standing.
4. When applying a wrist restraint, how many fingers should the nurse be able
to insert between the restraint and the patient’s skin?
A. Two fingers
B. One finger
C. Three fingers
D. None, it must be tight
Answer: A
Rationale: Inserting two fingers ensures the restraint is secure enough to prevent escape
but loose enough to prevent constriction of circulation and nerve damage.
5. What is the maximum duration for which a provider’s order for mechanical
restraints is valid for an adult patient?
A. 8 hours
B. 12 hours
C. 24 hours
D. 48 hours
Answer: C
Rationale: Restraint orders must be renewed every 24 hours for adults, following a face-
to-face assessment by the provider.
, 6. A patient is on Airborne Precautions. Which piece of Personal Protective
Equipment (PPE) is mandatory for the nurse?
A. Surgical mask
B. Goggles
C. Gown and gloves only
D. N95 respirator
Answer: D
Rationale: Airborne precautions require an N95 respirator or higher to filter small
droplets that remain suspended in the air.
7. In the chain of infection, what is the term for the place where a pathogen
survives and multiplies?
A. Portal of entry
B. Reservoir
C. Mode of transmission
D. Susceptible host
Answer: B
Rationale: A reservoir is a place where microorganisms survive, multiply, and await
transfer to a susceptible host (e.g., humans, animals, equipment).
8. The nurse is preparing a sterile field. Which action would contaminate the
field?
A. Opening the outermost flap away from the body
B. Dropping sterile items into the center of the field
C. Reaching across the sterile field to pick up an item
D. Keeping the sterile field above waist level
Answer: C
Rationale: Reaching across a sterile field introduces microorganisms from the nurse’s
clothing or arms, thus contaminating the field.
