NCLEX Pharmacology Quiz 25 Neurologic And Psychiatric Drugs

1. A side effect of cholinergic administration is:

Nausea

Diarrhea

Increase salivation

All of the above

Cholinergic drugs increase GI activity. causing all of these side effects.

Explanation

Cholinergic drugs increase GI activity. causing all of these side effects.

2. Joseph is child diagnosed with attention deficit disorder. Which of the following drugs is commonly used for his condition?

Methylphenidate (Ritalin)

Diethylpropion (Nobesine)

Phendimetrazine (Adipost)

Caffeine

Methylphenidate (Ritalin) is the drug of choice for attention deficit disorder. B and C are commonly used for exogenous obesity. Caffeine is a mild CNS stimulant that is not used for attention deficit disorder.

Explanation

Methylphenidate (Ritalin) is the drug of choice for attention deficit disorder. B and C are commonly used for exogenous obesity. Caffeine is a mild CNS stimulant that is not used for attention deficit disorder.

3. Which group of drugs mimics parasympathetic activity?

Cholinergic agents

Anticholinergic agents

Adrenergic agents

Antiadrenergic agents

Cholinergic drugs mimic the effects of the parasympathetic nervous system. Anticholinergic agents antagonize the parasympathetic nervous system. Adrenergic agents stimulate sympathetic nervous system. Antiadrenergic agents block the effect of the sympathetic nervous system.

Explanation

Cholinergic drugs mimic the effects of the parasympathetic nervous system. Anticholinergic agents antagonize the parasympathetic nervous system. Adrenergic agents stimulate sympathetic nervous system. Antiadrenergic agents block the effect of the sympathetic nervous system.

4. Amphetamines are included in the category of drugs of abuse because of their ability to:

Cause nervousness

Decrease weight

Raise blood pressure

Enhance performance

Drugs that produce a desired effect. such as feelings of euphoria and improved performance. tend to be overused and abused. Nervousness. decreased weight. and increased blood pressure are all effects of amphetamine. However. they are considered drugs of abuse because of their ability to enhance performance and produce a euphoric effect.

Explanation

Drugs that produce a desired effect. such as feelings of euphoria and improved performance. tend to be overused and abused. Nervousness. decreased weight. and increased blood pressure are all effects of amphetamine. However. they are considered drugs of abuse because of their ability to enhance performance and produce a euphoric effect.

5. Adrenergic blockers are contraindicated in:

Hypertension

Pheochromocytoma

Migraines

Obstructive airway disease

Adrenergic blockers tend to cause bronchoconstriction. so are therefore contraindicated in obstructive pulmonary disease.

Explanation

Adrenergic blockers tend to cause bronchoconstriction. so are therefore contraindicated in obstructive pulmonary disease.

6. Drugs that mimic sympathetic activity are known as:

Cholinergics

Anticholinergics

Adrenergics

Antiadrenergics

Drugs that mimic the effects of sympathetic activity are known as adrenergics.

Explanation

Drugs that mimic the effects of sympathetic activity are known as adrenergics.

7. Cholinergics are contraindicated in:

Tachycardia

Hypothyroidism

Hypotension

Asthma

Bronchial asthma is a contraindication of cholinergics because administration of cholinergics will cause bronchoconstriction.

Explanation

Bronchial asthma is a contraindication of cholinergics because administration of cholinergics will cause bronchoconstriction.

8. Cholinergic agents are used to:

Produce miosis

Facilitate neuromuscular blockade

Synergize neuromuscular blockers

Facilitate tricyclic activity

Miosis is a parasympathetic activity and is therefore the correct choice. B. C and D are incorrect because cholinergic agents are antidotes to neuromuscular blockers and tricyclic antidepressants.

Explanation

Miosis is a parasympathetic activity and is therefore the correct choice. B. C and D are incorrect because cholinergic agents are antidotes to neuromuscular blockers and tricyclic antidepressants.

9. Which of the following metabolic effects may be a consequence of administration of adrenergic agents?

Hypoglycemia

Metabolic acidosis

Hyperglycemia

Respiratory alkalosis

A. B. and D are incorrect because the effects of insulin are antagonized by adrenaline or adrenergic agents.

Explanation

A. B. and D are incorrect because the effects of insulin are antagonized by adrenaline or adrenergic agents.

10. The nurse would monitor for decreased effect of amphetamines when these drugs are given with:

Caffeine

Antidiabetic agents

Tricyclic antidepressants

All of the above

Antidiabetic agents tend to decrease the effectiveness of amphetamines. A and C increase the effects of amphetamines.

Explanation

Antidiabetic agents tend to decrease the effectiveness of amphetamines. A and C increase the effects of amphetamines.
