Example Question #31 : Drug Identification

You are the nurse taking care of a patient who is experiencing a panic attack. You are instructed to give the patient a dose of lorazepam. Which of the drug classes below describes lorazepam?

Possible Answers:

Benzodiazepine

Barbiturate

Alpha-blocker

Beta-blocker

Amphetamine

Correct answer:

Benzodiazepine

Explanation:

The correct answer is "benzodiazepine," as lorazepam, also known as Ativan, is a benzodiazepine drug. Benzodiazepines act by increasing the efficacy of the neurotransmitter, GABA, when it acts upon its particular receptors. They have potent anti-anxiety properties, among other properties, and are frequently given during the initial phase of a panic attack to calm the patient.

On the other hand, the other choices are incorrect. Phenobarbital is an example of a barbiturate. Proproanolol is an example of a beta-blocker. Tamsulosin is an example of an alpha-blocker. Methamphetamine is an example of an amphetamine.

Which of the following is an antidote to opioid overdose?

Possible Answers:

Naloxone

Glucagon

Flumazenil

N-acetylcysteine

Example Question #7 : Anti Inflammatory And Pain Treatments

Levodopa is not generally given alone due to what side effects?

Possible Answers:

Heart palpitations

Delirium

Tremor

Nausea, vomiting, and anorexia

Correct answer:

Nausea, vomiting, and anorexia

Explanation:

Levodopa (L-DOPA), a common treatment for Parkinson's disease, is generally given in combination with carbidopa or another peripheral dopa-decarboxylase inhibitor. This is because levodopa alone will stimulate dopamine receptors in the GI tract and the chemotrigger receptor zone (CTZ) in the brain, resulting in nausea, vomiting and anorexia. A peripheral dopa-decarboxylase inhibitor prevents levodopa from being prematurely converted into dopamine in the adrenal glands or other peripheral tissues.
