Question 1

Which of the following would inhibit the function of the autonomic nervous system?

Accepted Answer

Drugs that prevent the storage of neurotransmitter in vesicles would inhibit the function of the autonomic nervous system by reducing the availability of neurotransmitters for release into the synaptic cleft, thereby decreasing neural signaling.

Question 2

The patient receives methyldopa (Aldomet),an adrenergic drug.The nurse determines that the patient is having side effects when the patient makes which statement?

Accepted Answer

C

Question 3

The student nurse asks the nursing instructor,"Do the medications we are studying actually make more neurotransmitters?" What is the best response by the nursing instructor?

Accepted Answer

Medications can only increase or decrease the action of neurotransmitters. While some medications may indirectly increase the amount of neurotransmitters available through their effect on receptors or enzymes that regulate neurotransmitter levels, they do not actually create new neurotransmitters.

Question 4

The patient is quadriplegic and receives oxybutynin (Ditropan),an anticholinergic drug,to increase his bladder capacity.What is an important assessment of this patient by the nurse?

Accepted Answer

Anticholinergic medications like oxybutynin can cause constipation as a side effect, so it is important for the nurse to assess the patient for this potential complication. The other options are not necessarily related to the use of oxybutynin.

Question 5

The patient receives metaproterenol (Alupent),an adrenergic drug.A consulting physician orders carteolol (Cartrol),a beta blocker.What best describes the nurse's assessment?

Accepted Answer

Carteolol is a beta blocker that can antagonize the effects of metaproterenol, which is also a beta agonist. This means that metaproterenol may not be as effective in managing the patient's symptoms when used together with carteolol.

Question 6

The physician orders dicyclomine (Bentyl),an anticholinergic drug,for a patient.What is the nurse's priority assessment prior to administering this drug?

Accepted Answer

The priority assessment prior to administering dicyclomine (Bentyl) is to assess whether the patient is able to urinate, as anticholinergic drugs can cause urinary retention. This is a potentially serious adverse effect that could lead to bladder distention, kidney damage, or even urinary tract infection. Light sensitivity, history of alcoholism, and dizziness upon standing are not specifically related to the administration of dicyclomine.

Question 7

The nurse is preparing to administer medications to a group of patients.One of the medications is atropine,an anticholinergic drug.This drug is contraindicated in which patient?

Accepted Answer

Atropine is contraindicated in patients with glaucoma because it can worsen the condition due to its ability to cause pupil dilation and increase intraocular pressure. It is not contraindicated in patients with hyperthyroidism, a hiatal hernia, or lung cancer.

Question 8

The nursing instructor teaches the student nurses about the nervous system.The instructor determines that learning has occurred when the students make which statement(s)? Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

A) Correct - The central nervous system is made up of the brain and spinal cord.
B) Incorrect - The peripheral nervous system has both sensory and motor functions.
C) Incorrect - The somatic nervous system is responsible for voluntary movements of skeletal muscles and not for controlling GI tract function.
D) Correct - The nervous system helps us react and respond to environmental changes.
E) Correct - The somatic nervous system controls voluntary movements such as walking and moving our limbs.

Question 9

A person who had her adrenergic receptors activated would experience

Accepted Answer

Adrenergic receptors are activated by the hormone adrenaline, which is released during the fight-or-flight response. This response prepares the body for intense physical activity, such as running away from danger, by increasing heart rate, dilating pupils, and increasing blood flow to skeletal muscles.

Question 10

The physician ordered prazosin (Minipress),an alpha-adrenergic blocker,for the patient.The nurse plans to do medication education.What will the best plan of the nurse include?

Accepted Answer

Prazosin can cause orthostatic hypotension, and hot baths or showers can exacerbate this effect by causing vasodilation and further lowering blood pressure.

Question 11

The nurse is preparing to administer medications to a group of patients.One of the medications is benztropine (Cogentin),an anticholinergic drug.This drug is contraindicated in which patient?

Accepted Answer

The answer of The nurse is preparing to administer medications...

Question 12

The nurse has been doing medication education for the patient receiving atenolol (Tenormin),a beta blocker.The nurse determines that learning has occurred when the patient makes which statement?

Accepted Answer

Monitoring pulse is important when taking atenolol, as it can slow down the heart rate. Option B is incorrect because the patient should not stop the medication without consulting with their healthcare provider. Option C is incorrect as atenolol can be used with caution in patients with glaucoma. Option D is incorrect as the patient may still be able to have coffee while taking atenolol, as long as they monitor their heart rate and blood pressure.

Question 13

The ability of a person to use his arm muscles to lift a weight is primarily regulated by

Accepted Answer

The somatic nervous system is responsible for voluntary muscle movement, which includes the ability to use arm muscles to lift a weight. The sympathetic nervous system regulates involuntary responses such as fight or flight, while the autonomic nervous system controls internal organs and functions, and the central nervous system includes the brain and spinal cord.

Question 14

The preop patient will be receiving glycopyrrolate (Robinul),an anticholinergic drug,and asks the nurse,"Why do I need to have that shot?" What is the best response by the nurse?

Accepted Answer

Glycopyrrolate is an anticholinergic drug that is often given preoperatively to decrease respiratory secretions, which can help prevent complications such as aspiration pneumonia. It does not affect urinary output, breathing, or blood pressure in the same way.

Question 15

Which of the following responses are regulated by the sympathetic nervous system?

Accepted Answer

The answer of Which of the following responses are regulated...

Question 16

The physician has ordered bethanechol (Urecholine),a cholinergic drug,for the patient with urinary retention.The patient also has an enlarged prostate gland.What is the priority action by the nurse?

Accepted Answer

The answer of The physician has ordered bethanechol (Urecholine),a cholinergic...

Question 17

The nurse has completed medication education about pyridostigmine (Mestinon),an indirect cholinergic drug,for the patient with myasthenia gravis.The nurse determines that learning has occurred when the patient makes which statement?

Accepted Answer

Pyridostigmine must be taken on time to maintain muscle strength and prevent symptoms of myasthenia gravis, as it helps improve communication between nerves and muscles.

Question 18

The nursing instructor teaches the student nurses about the autonomic nervous system.The instructor determines that learning has occurred when the students make which statement(s)? Credit will be given only if all correct choices and no incorrect choices are selected.

Accepted Answer

The answer of The nursing instructor teaches the student nurses...

Question 19

Which receptor type is found at the ganglionic synapse of both the sympathetic and parasympathetic nervous systems?

Accepted Answer

Both the sympathetic and parasympathetic ganglionic synapses use nicotinic receptors. Alpha and beta receptors are found on target organs, while muscarinic receptors are found on postganglionic parasympathetic target organs.

Question 20

Which statement is accurate concerning drugs classified as adrenergic antagonists?

Accepted Answer

Adrenergic antagonists have actions that are opposite to sympathomimetics, meaning that they block or inhibit the actions of the sympathetic nervous system. They are not anticholinergics, which are a separate class of drugs that block the neurotransmitter acetylcholine.
