Example Questions

Example Question #3 : Neural Pharmacology

What class of drug is quetiapine?

Possible Answers:

Tricyclic antidepressant

Serotonin antagonist and reuptake inhibitor (SARI)

Norepinephrine reuptake inhibitor

Atypical antipsychotic

Correct answer:

Atypical antipsychotic

Explanation:

Quetiapine is classified as an atypical antipsychotic. Quetiapine is a powerful antihistamine and has pharmacological action at many receptor types: it is a serotonin, dopamine, and adrenergic antagonist.

Example Question #2 : Neural Pharmacology

Which of the following antidepressants is also used for smoking cessation?

Possible Answers:

Buspirone

Bupropion

Venlafaxine

Amitriptyline

Correct answer:

Bupropion

Explanation:

Bupropion is an antidepressant used for smoking cessation. None of the other medications listed are used for smoking cessation. 

Example Question #4 : Neural Pharmacology

Sertraline, paroxetine, and citalopram, are all classified as what type of antidepressant? 

Possible Answers:

Monoamine oxidase inhibitors (MAOIs)

Serotonin–norepinephrine reuptake inhibitors (SNRIs)

Selective serotonin re-uptake inhibitors (SSRIs)

Serotonin modulator and stimulators (SMSs)

Correct answer:

Selective serotonin re-uptake inhibitors (SSRIs)

Explanation:

Sertraline, paroxetine, and Citalopra are all selective serotonin re-uptake inhibitors (SSRIs). This class of drug works by blocking serotonin re-uptake in the synapse, thus increasing post-synaptic serotonin stimulation. They are one of the most widely used class of antidepressants in the United States and many parts of the world.

Example Question #21 : Drug Identification

Zolpidem belongs in what drug class?

Possible Answers:

Benzodiazepine

Nonbenzodiazepine hypnotic

Selective serotonin re-uptake inhibitor (SSRI)

Orexin antagonist 

Correct answer:

Nonbenzodiazepine hypnotic

Explanation:

Zolpidem is a short acting nonbenzodiazepine hypnotic. It's actions are similar to benzodiazepine drugs in that it stimulates GABAa receptors at the same location as benzodiazepines. It is used in insomnia for initiating sleep, though it's short half life (3 hours) means it is not generally considered effective for maintaining sleep. 

Example Question #6 : Neural Pharmacology

All of the following are common anticonvulsants except __________.

Possible Answers:

lamotrigine

carbamazepine

risperidone

valproate

Correct answer:

risperidone

Explanation:

All of the answers given are common anticonvulsant medications except risperidone, which is a second generation atypical antipsychotic used in schizophrenia and bipolar disorder.

Example Question #11 : Neural Pharmacology

Lamotrigine carries a black-box warning about what side effect?

Possible Answers:

Aseptic meningitis

DRESS syndrome (drug reaction/rash with eosinophilia and systemic symptoms)

Stevens–Johnson syndrome

All of these

Correct answer:

All of these

Explanation:

Lamotrigine carries a black box warning about the following side effects:

  • Stevens–Johnson syndrome
  • Toxic epidermal necrolysis
  • DRESS syndrome (drug reaction/rash with eosinophilia and systemic symptoms)
  • Aseptic meningitis

Example Question #111 : Pharmacology

Phenelzine is what class of drug?

Possible Answers:

Tricyclic antidepressant

Monoamine oxidase inhibitor (MAOI) 

Alpha adrenergic agonist

Narcotic

Correct answer:

Monoamine oxidase inhibitor (MAOI) 

Explanation:

Phenelzine is a monoamine oxidase inhibitor (MAOI). Drugs in this class work by inhibition of monoamine oxidase enzymes, the enzymes responsible for the break down of serotonin, dopamine, and adrenaline. 

Example Question #112 : Pharmacology

What class of drugs is diazepam?

Possible Answers:

Methaqualone analogue

Benzodiazepine

Nonbenzodiazepine sedative

Barbituate

Correct answer:

Benzodiazepine

Explanation:

Diazepam is a benzodiazepine. This class of drugs works by potentiating the effects of GABA, our primary inhibitory neurotransmitter, at the GABAa receptor.

Example Question #114 : Pharmacology

Bromocriptine belongs to what class of drug?

Possible Answers:

Peripheral dopamine decarboxylase inhibitor 

Anxiolytic

Anticholinergic

Dopamine agonist

Correct answer:

Dopamine agonist

Explanation:

Bromocriptine is a dopamine agonist used in the treatment for Parkinson's disease, pituitary tumors, and type 2 diabetes.  

Example Question #112 : Pharmacology

A patient taking haloperidol complains of abnormal, unintentional movements of his tongue and face. The nurse knows that the patient is experiencing which of the following side effects of haloperidol?

Possible Answers:

Convulsions and seizures

Dizziness and weakness

Increased anxiety

Tardive dyskinesia

Neuroleptic malignant syndrome

Correct answer:

Tardive dyskinesia

Explanation:

All of the listed options are side effects of haloperidol, but tardive dyskinesia (TD) is the only one that manifests with involuntary, dyskinetic movements in their face, lips, tongue, trunk, and extremities. TD more frequently occurs among elderly female patients taking long-term dopamine-antagonist medications. Dizziness, weakness, convulsions, seizures, and anxiety are also side effects of haloperidol. Neuroleptic Malignant Syndrome presents with fever and high/unstable blood pressure, muscle cramps and tremors, altered mental status (such as delirium, agitation, or a coma).
