1. What is the primary therapeutic purpose of centrally acting
skeletal muscle relaxants?
A. Increase skeletal muscle strength
B. Treat bacterial infections of muscle
C. Reduce painful muscle spasms and associated discomfort
D. Increase bone mineral density
Rationale: Centrally acting skeletal muscle relaxants are primarily
used to decrease muscle spasms and the pain associated with acute
musculoskeletal conditions.
2. Most centrally acting skeletal muscle relaxants produce their
effects primarily by acting on the:
A. Neuromuscular junction
B. Skeletal muscle fibers directly
C. Central nervous system
D. Peripheral sensory nerves only
Rationale: These medications generally reduce excessive skeletal
muscle activity through actions within the CNS rather than directly
relaxing muscle fibers.
,3. Which condition is most commonly treated with short-term use
of a centrally acting muscle relaxant?
A. Chronic hypertension
B. Acute low-back muscle spasm
C. Bacterial myositis
D. Osteoporosis
Answer: B. Acute low-back muscle spasm
Rationale: Centrally acting muscle relaxants are commonly prescribed
for acute painful musculoskeletal conditions such as low-back or neck
spasms.
4. Which adverse effect is particularly common with centrally acting
muscle relaxants?
A. Severe hyperglycemia
B. Drowsiness
C. Increased visual acuity
D. Hypercalcemia
Rationale: CNS depression frequently produces drowsiness or
sedation.
5. A patient taking a centrally acting muscle relaxant should
generally be cautioned about:
A. Increasing caffeine intake
B. Driving or operating machinery until the drug's effects are known
C. Taking extra doses before driving
D. Exercising immediately after every dose
Rationale: Sedation, dizziness, and impaired coordination can make
driving or operating machinery hazardous.
6. Which medication is classified as a centrally acting skeletal
muscle relaxant?
,A. Acetaminophen
B. Cyclobenzaprine
C. Amoxicillin
D. Furosemide
Rationale: Cyclobenzaprine is a centrally acting skeletal muscle
relaxant used primarily for acute painful muscle spasms.
7. Cyclobenzaprine is structurally related to which class of
medications?
A. Benzodiazepines
B. Opioids
C. Tricyclic antidepressants
D. Penicillins
Rationale: Cyclobenzaprine is structurally related to tricyclic
antidepressants, which helps explain some of its anticholinergic
effects.
8. Which effect may occur because of cyclobenzaprine's
anticholinergic activity?
A. Excessive salivation
B. Diarrhea
C. Dry mouth
D. Increased urination
Rationale: Anticholinergic activity can decrease secretions and cause
dry mouth.
9. Which patient should use particular caution with
cyclobenzaprine?
A. A healthy young adult with acute back strain
B. A patient with significant cardiac disease
C. A patient with seasonal allergies
D. A patient with mild acne
, Rationale: Cyclobenzaprine has important cardiovascular precautions
and should be used cautiously or avoided in certain cardiac
conditions.
10. Which symptom may indicate excessive CNS depression from a
muscle relaxant?
A. Increased alertness
B. Extreme somnolence
C. Increased appetite
D. Excessive energy
Rationale: Excessive sedation can indicate significant CNS depression
and may become dangerous, particularly when other CNS
depressants are involved.
11. Which medication is a centrally acting muscle relaxant
commonly used for acute musculoskeletal pain?
A. Insulin
B. Methocarbamol
C. Warfarin
D. Levothyroxine
Rationale: Methocarbamol is a centrally acting skeletal muscle
relaxant used as an adjunct to rest and physical therapy for acute
musculoskeletal conditions.
12. What is a common adverse effect of methocarbamol?
A. Severe hypertension
B. Dizziness and drowsiness
C. Hyperthyroidism
D. Increased muscle tone
Rationale: CNS depression may produce dizziness, drowsiness, and
impaired coordination.
