MULTIPLE CHOICE
| A. | Dantrolene (Dantrium) |
| B. | Neostigmine methylsulfate (Prostigmin) |
| C. | Ether |
| D. | Baclofen (Lioresal) |
ANS: B
| Feedback | |
| A | Dantrolene is a direct-acting skeletal muscle relaxant given for the treatment of neuroleptic malignant syndrome associated with the use of antipsychotic agents. |
| B | Neostigmine methylsulfate is an antidote to neuromuscular blocking agents. Additional measures to implement include artificial respirations with oxygen and atropine sulfate for bradycardia and hypotension. |
| C | Ether is a general anesthetic. |
| D | Baclofen is a skeletal muscle relaxant. |

| A. | It interrupts reflexes at the level of the spinal cord. |
| B. | It acts directly on the skeletal muscles to reduce spasticity. |
| C. | It interrupts transmission of impulses from motor nerves to muscles at the skeletal neuromuscular junction. |
| D. | It produces generalized mild weakness of skeletal muscles and decreases the force of reflex muscle contractions. |
ANS: A
| Feedback | |
| A | Baclofen is a gamma-aminobutyric acid derivative that interrupts polysynaptic reflexes at the level of the spinal cord. |
| B | Baclofen does not appear to act directly on the skeletal muscles. |
| C | Interrupting transmission of impulses from motor nerves to muscles at the skeletal neuromuscular junction is the mechanism of action of neuromuscular blocking agents. |
| D | Producing generalized mild weakness of skeletal muscles and decreasing the force of reflex muscle contractions is the mechanism of action of dantrolene. |

| A. | Edrophonium (Tensilon) |
| B. | Dantrolene (Dantrium) |
| C. | Baclofen (Lioresal) |
| D. | Metaxolone (Skelaxin) |
ANS: B
| Feedback | |
| A | Edrophonium is an antidote for neuromuscular blocking agents. |
| B | Dantrolene, a direct-acting skeletal muscle relaxant, is used to treat neuroleptic malignant syndrome associated with the use of antipsychotic agents. |
| C | Baclofen is a skeletal muscle relaxant used for the treatment of muscle spasticity resulting from multiple sclerosis and cerebral palsy. |
| D | Metaxolone is used for muscle spasms. |

| A. | Pain |
| B. | Disturbed Body Image |
| C. | Risk for Injury |
| D. | Self-Care Deficit |
ANS: A
| Feedback | |
| A | Pain is the highest priority, according to Maslow’s hierarchy of needs. Succinylcholine, a neuromuscular blocking agent, is used to paralyze muscles while a patient is on a ventilator. Neuromuscular blocking agents do not relieve pain. |
| B | Disturbed Body Image is not a priority for this situation, although it does apply. |
| C | Risk for Injury is not as great a priority for this situation. |
| D | Self-Care Deficit is not as great a priority for this situation. |
