A patient who is experiencing alcohol withdrawal is given a benzodiazepine. The nurse understands that this drug is effective because:
a. the alcohol does not interact with the benzodiazepine.
b. the benzodiazepine potentiates alcohol withdrawal symptoms.
c. the benzodiazepine relieves muscle spasms and spasticity.
d. the patient has a cross-dependence to the benzodiazepine.
D
Benzodiazepines are given to ease withdrawal from alcohol because of cross-dependence with these drugs and alcohol, enabling the benzodiazepine to suppress withdrawal symptoms. Alcohol and benzodiazepines can potentiate one another. The benzodiazepine does not potentiate with-drawal symptoms. Benzodiazepines relieve muscle spasms, but this is not why they are given for alcohol withdrawal.
