1. Which skeletal effect is associated with prolonged immobility?
A) Increased bone density
B) Disuse osteoporosis from impaired calcium absorption
C) Improved joint mobility
D) Muscle hypertrophy
Correct Answer: B) Disuse osteoporosis from impaired calcium absorption
Rationale: Prolonged immobility impairs calcium absorption and leads to disuse
osteoporosis, weakening bones and increasing fracture risk. Increased bone
density and muscle hypertrophy do not occur with inactivity, and joint mobility
decreases rather than improves. Recognizing this complication guides early
mobility and calcium monitoring.
2. Which respiratory complication is most associated with bedrest?
A) Increased lung expansion
B) Decreased mucus production
C) Atelectasis and hypostatic pneumonia
D) Improved oxygenation
Correct Answer: C) Atelectasis and hypostatic pneumonia
Rationale: Immobility causes alveolar collapse and pooled secretions, leading to
atelectasis and hypostatic pneumonia. Lung expansion and oxygenation decline
rather than improve, and mucus production is not decreased. Incentive
,spirometry, deep breathing, and repositioning help prevent these
complications.
3. A joint that is freely movable is classified as which type?
A) Diarthrosis
B) Synarthrosis
C) Amphiarthrosis
D) Slightly movable
Correct Answer: A) Diarthrosis
Rationale: Diarthrosis joints are freely movable and include most joints of the
limbs. Synarthrosis joints are nonmovable, amphiarthrosis joints are slightly
movable, and slightly movable is a description rather than a classification. Joint
classification guides mobility assessment and rehabilitation.
4. Which statement accurately describes passive range of motion?
A) The patient moves the joint independently
B) The patient resists the nurse's movement
C) The patient moves with some assistance
D) The nurse moves the joint without patient assistance
Correct Answer: D) The nurse moves the joint without patient assistance
Rationale: Passive range of motion occurs when the nurse moves the patient's
joint through its full range without patient effort. Active ROM is independent
movement, active-assistive involves partial patient effort, and resistive exercise
is not ROM. Passive ROM maintains joint mobility in immobile patients.
, 5. Which skin function is essential for calcium and bone health?
A) Protection
B) Vitamin D synthesis
C) Excretion
D) Thermoregulation
Correct Answer: B) Vitamin D synthesis
Rationale: The skin synthesizes vitamin D when exposed to ultraviolet light,
which is essential for calcium absorption and bone health. Protection, excretion,
and thermoregulation are important but do not directly support calcium
metabolism. Vitamin D deficiency can impair bone mineralization.
6. Which finding characterizes a stage 1 pressure injury?
A) Nonblanchable erythema of intact skin
B) Partial-thickness skin loss with blister
C) Full-thickness skin loss
D) Exposed bone or tendon
Correct Answer: A) Nonblanchable erythema of intact skin
Rationale: A stage 1 pressure injury presents as intact skin with localized
nonblanchable erythema. Partial-thickness loss is stage 2, full-thickness loss is
stage 3, and exposed bone is stage 4. Early identification of nonblanchable
redness allows preventive intervention before skin breakdown.
7. Which precaution is required for a client with tuberculosis?
A) Contact precautions
