NR224 WEEK 3 EDAPTS - MOBILITY
EXAM QUESTIONS AND ANSWERS
1. Which metabolic change is most commonly associated with prolonged immobility?
A. Increased basal metabolic rate
B. Decreased calcium excretion
C. Enhanced protein synthesis
D. Negative nitrogen balance
Answer: D
Conceptual Explanation: Immobility leads to the breakdown of muscle protein, resulting
in nitrogen being excreted more than it is ingested, leading to a negative nitrogen balance.
2. A nurse is caring for a patient who has been bedridden for two weeks. Which respiratory
complication should the nurse monitor for?
A. Pneumothorax
B. Pulmonary hypertension
C. Increased surfactant production
,D. Atelectasis
Answer: D
Conceptual Explanation: Atelectasis, or the collapse of alveoli, is a common respiratory
complication of immobility due to shallow breathing and pooling of secretions.
3. When assessing a patient for orthostatic hypotension, which finding indicates a positive
result?
A. Stabilization of blood pressure within 1 minute of standing
B. An increase in diastolic blood pressure of 5 mmHg when sitting
C. A decrease in heart rate of 10 beats per minute
D. A drop in systolic blood pressure of 20 mmHg when standing
Answer: D
Conceptual Explanation: Orthostatic hypotension is defined as a drop in systolic BP of at
least 20 mmHg or diastolic BP of at least 10 mmHg within three minutes of rising to an
upright position.
4. Which intervention is most effective in preventing deep vein thrombosis (DVT) in an
immobile patient?
A. Massaging the lower extremities daily
B. Placing a pillow under the knees
C. Restricting fluid intake to reduce edema
, D. Applying sequential compression devices (SCDs)
Answer: D
Conceptual Explanation: SCDs promote venous return by mimicking the muscle pump
action, significantly reducing the risk of DVT.
5. The nurse is assisting a patient with a weak left leg to walk using a cane. Where should the
cane be placed?
A. On the right side
B. On the left side
C. Directly in front of the patient
D. Behind the patient’s heels
Answer: A
Conceptual Explanation: A cane should be held on the stronger side (the unaffected side)
to provide maximum support and balance for the weaker limb.
6. Which type of exercise involves muscle contraction without shortening of the muscle
fibers?
A. Isotonic exercise
B. Isometric exercise
C. Isokinetic exercise
D. Aerobic exercise
