Question 1

Antipsychotic medications may cause the following side effects:

Accepted Answer

Antipsychotic medications may cause extrapyramidal symptoms, dizziness, and drowsiness.

Question 2

Which division of the autonomic nervous system (ANS) functions during restful situations?

Accepted Answer

The parasympathetic nervous system (PSNS) is the division of the ANS, which functions during restful situations.

Question 3

Which of the following combinations reflect the specificity of beta-receptors?

Accepted Answer

The primary NTs of the SNS are norepinephrine and epinephrine. Four main types of receptors respond to these NTs. Alpha-1 (a₁)-receptors are located in peripheral blood vessels, the heart, and the eyes; a₂-receptors are primarily located on smooth muscle beta-1 receptors are primarily located in the heart muscle; and beta-2 receptors are located in the respiratory system, blood vessels, and elsewhere in the body.

Question 4

The primary side effects of anticholinergic drugs, such as benztropine for PD, include:

Accepted Answer

Anticholinergic medications cause dry mouth, constipation, urinary retention, blurred vision, and confusion.

Question 5

What are the two primary divisions of the nervous system?

Accepted Answer

The CNS is composed of the brain and the spinal cord, whereas the PNS is located outside the CNS and consists of the afferent (sensory) and efferent (motor) branches. The efferent division is further divided into the somatic and autonomic systems. The ANS consists of two main branches: the SNS and the PSNS.

Question 6

Parkinson disease (PD) is characterized by a deficiency of which of the following transmitters?

Accepted Answer

PD is a progressive disorder of the basal ganglia and is associated with the loss or deficiency of the neurotransmitter (NT) dopamine

Question 7

Sumatriptan (Imitrex) for migraine headaches can be administered:

Accepted Answer

The routes of administration for Imitrex are orally, nasally, and subcutaneous injection.

Question 8

During a fight-or-flight response:

Accepted Answer

During the fight-or-flight stress response, the sympathetic nervous system (SNS) shuts down the nonessential systems of the body, which redirects energy to other areas such as the muscular system.

Question 9

Which of the following statements concerning insomnia is false?

Accepted Answer

Insomnia is a complaint of difficulty initiating sleep, difficulty maintaining sleep, or waking up too early; its prevalence increases with age and is more common in women than men. Insomnia can be related to medication use.

Question 10

Which of the following is not a state in the transmission of a chemical message?

Accepted Answer

In the transmission of a chemical message from one neuron to another, three basic states need to occur within each neuron: polarized, depolarized, and repolarized.

Question 11

Injectable immune modifiers such as interferons share what common storage requirement?

Accepted Answer

Immune modulators such as interferon must be kept refrigerated and protected from light.

Question 12

Which of the following is not a primary function of the nervous system?

Accepted Answer

The four main functions of the nervous system include: (1) sending impulses to the CNS; (2) sending impulses back to the peripheral nervous system (PNS); (3) coordinating the activities of all parts of the nervous system (e.g., those functions that rely on outside stimulation), and (4) detecting various changes in the body, such as temperature, acting as a sensory organ.

Question 13

Donepezil (Aricept) is used as an agent that treats the symptoms:

Accepted Answer

Aricept is an acetylcholinesterase inhibitor approved for use in treating the symptoms of Alzheimer disease.

Question 14

Which of the following is a primary neurotransmitter of the SNS?

Accepted Answer

The main neurotransmitters of the SNS are norepinephrine and epinephrine.

Question 15

All anticonvulsant medications need the following auxiliary label:

Accepted Answer

All anticonvulsant medications require a physician to guide the discontinuation of the medication to avoid seizure activity; therefore these medications should not be abruptly stopped. Only suspension medications require shaking, only benzodiazepines used as anticonvulsants require the federal law prohibits cautionary warning label, and not all anticonvulsant medications need to be taken with a full glass of water.

Question 16

Which of the following drugs used as anticonvulsants require the auxiliary label: "Caution: Federal law prohibits the transfer of this drug to any person other than the patient for whom it was prescribed."

Accepted Answer

Valium is a Schedule IV controlled substance (C-IV) medication.

Question 17

Which of the following is not a tricyclic antidepressant?

Accepted Answer

Nardil is a monoamine oxidase inhibitor (MAOI).

Question 18

Which of the following is the mood-changing drug of choice for bipolar disorder?

Accepted Answer

Treatment for bipolar disorder primarily involves the use of mood-stabilizing drugs such as lithium (Eskalith).

Question 19

EpiPens (epinephrine autoinjectors) need an auxiliary label because they:

Accepted Answer

Although injectable drugs do not need an auxiliary label when administered by a physician or nurse, EpiPens need auxiliary labels because these are carried by the patient for emergency use.

Question 20

Psychosis can be:

Accepted Answer

Psychosis is defined as a mental illness characterized by the loss of contact with reality and may be a True mental illness, attributable to an underlying medical condition (e.g., dementia, drug withdrawal syndromes), or induced by substances such as medications, recreational drugs, or poisons.
