QUESTIONS & CORRECT ANSWERS |
LATEST UPDATED VERSION
1. The nurse has attended a continuing education conference on the
physiological effects of prolonged immobility. The nurse is correct to
state that prolonged immobility can result in:
A) Vasoconstriction and venous stasis
B) Hypertension and irregular heart rate
C) Increased cardiac output and decreased peripheral resistance
D) Decreased venous return and increased arterial blood flow
Correct Answer: A
Rationale: Prolonged immobility leads to venous stasis and pooling of
blood in the lower extremities due to decreased muscle pump activity.
This increases the risk of deep vein thrombosis (DVT) and other
cardiovascular complications .
, 2. The nurse is caring for a client who is confined to bed. While providing
care, the nurse raises the height of the bed to a comfortable working
position. The rationale for the nurse's action is to:
A) Allow the nurse to stand with the feet closer together while working
B) Narrow the nurse's base of support making the nurse more stable
C) Prevent a shift in the nurse's base of support making the nurse more
stable
D) Shift the nurse's center of gravity away from the base of support
Correct Answer: C
Rationale: Raising the bed to a comfortable height maintains a proper
base of support and prevents shifting of the nurse's center of gravity,
improving stability and reducing the risk of injury. A wider base of
support increases stability, and the center of gravity should remain over
the base of support .
3. The nurse is caring for a client who has limited mobility. Which of the
following actions should the nurse take to decrease cardiovascular
complications associated with limited mobility?
, A) Limit fluid to decrease workload on the heart
B) Have the client do dorsiflexion of the feet and ankles
C) Perform passive range of motion exercises once a day
D) Place the client in a flat position to promote venous return
Correct Answer: B
Rationale: Dorsiflexion exercises promote venous return and reduce the
risk of deep vein thrombosis. Fluid should not be restricted without
indication. Passive ROM once daily is insufficient, and the flat position
may promote venous pooling .
4. The nurse is providing postoperative care to a client following spinal
surgery. Which intervention is most important to prevent deep vein
thrombosis (DVT)?
A) Apply warm compresses to the lower extremities
B) Encourage early ambulation
, C) Restrict fluid intake
D) Maintain strict bed rest
Correct Answer: B
Rationale: Early ambulation stimulates venous return and reduces venous
stasis, which is critical in preventing DVT formation postoperatively. Bed
rest actually increases DVT risk .
5. The nurse has reinforced teaching with a client about risk factors for
deep vein thrombosis (DVT). Which of the following risk factors
identified by the client indicates a need for further teaching?
A) Oral contraceptive use
B) Prolonged immobility
C) Intake of foods high in calcium
D) Smoking
Correct Answer: C
