Question 1

The nurse is preparing to administer a drug and learns that it is an indirect-acting cholinergic agonist.The nurse understands that this drug

Accepted Answer

Agents that inhibit cholinesterase,which is the enzyme that destroys acetylcholine,indirectly enhance the actions of acetylcholine.

Question 2

The nurse is teaching a patient who is going on a cruise about the use of transdermal scopolamine  .What information will the nurse include when teaching this patient?

Accepted Answer

The transdermal scopolamine patch is designed to last for 72 hours.The patient should be taught to change it every 3 days.It works best when worn at all times and not just for symptomatic relief.The patch should be applied behind the ear.Patients should not restrict fluids.

Question 3

The nurse is teaching a patient who will begin taking bethanechol (Urecholine).Which statement by the patient indicates a need for further teaching?

Accepted Answer

Patients taking bethanechol should be instructed to report increased salivation and diaphoresis since they can be early signs of overdosing.They should also be taught to rise slowly to avoid orthostatic hypotension and to hold the drug if their heart rate is low.

Question 4

The nurse administers bethanechol (Urecholine)to a patient to treat urinary retention.After 30 minutes,the patient voids 800 mL of urine and reports having a loose stool but no cramping or gastrointestinal pain.The patient's blood pressure is 110/70 mm Hg.The nurse will perform which action?

Accepted Answer

The patient is exhibiting desired effects and mild side effects of bethanechol,so the nurse should record information and continue to monitor the patient.There is no need to notify the provider,give an antidote,or repeat the dose.

Question 5

Cholinergic drugs have specific effects on the body.What are the actions of cholinergic medications? (Select all that apply. )

Accepted Answer

Decreasing heart rate,stimulating gastric muscles,dilating blood vessels,increasing salivation,and constricting pupils are actions of the cholinergic drugs.

Question 6

The nurse is caring for a postoperative patient and notes that the patient received atropine sulfate preoperatively.Which assessment finding would prompt the nurse to notify the provider?

Accepted Answer

These are all side effects of atropine.Absent bowel sounds can indicate a paralytic ileus.The other side effects are not harmful.

Question 7

The nurse is preparing to administer benztropine (Cogentin)to a patient who has Parkinson's disease.When performing an assessment,which aspect of the patient's history would cause the nurse to hold the medication and notify the provider?

Accepted Answer

Patients who have glaucoma should not take anticholinergic medications.

Question 8

A nursing student asks why a direct-acting cholinergic agonist drug that is selective to muscarinic receptors is described as being non-specific.The nurse will explain that this is because

Accepted Answer

Although drugs classified as direct-acting cholinergic agonists are primarily selective for muscarinic receptors,they are non-specific because muscarinic receptors are located in different sites,causing actions in various organs.They are not affected differently by cholinesterase activity and have negligible actions on nicotinic receptors.

Question 9

The nurse is teaching a patient about the use of an anticholinergic medication.What information will the nurse include when teaching this patient about this medication?

Accepted Answer

Anticholinergic medications cause dry mouth,so patients should be advised to use gum or lozenges to counter this side effect.Anticholinergics cause increased heart rate and increased blood pressure.Anticholinergics can cause urinary retention so patients should not increase fluid intake.

Question 10

A patient who has Parkinson's disease will begin treatment with benztropine (Cogentin).Which symptom of Parkinson's disease would be a contraindication for this drug?

Accepted Answer

Tardive dyskinesia is a contraindication for this drug.

Question 11

The nurse is caring for a male patient with myasthenia gravis who will begin taking ambenonium chloride (Mytelase).When performing a health history,the nurse will be concerned about a history of which condition in this patient?

Accepted Answer

This drug is a reversible cholinesterase inhibitor and is given to increase muscle strength.Cholinesterase inhibitors are contraindicated in patients with urinary tract obstruction.

Question 12

The nurse is preparing to administer the anticholinergic medication benztropine (Cogentin)to a patient who has Parkinson's disease.The nurse understands that this drug is used primarily for which purpose?

Accepted Answer

Antiparkinson-anticholinergic drugs are used mainly to reduce tremors and muscle rigidity.

Question 13

Which cholinesterase inhibitor would be prescribed for a patient who has Alzheimer's disease?

Accepted Answer

Donepezil is used to treat Alzheimer's disease.Ambenonium and neostigmine are used to treat myasthenia gravis.Benztropine is used to treat Parkinson's disease.

Question 14

The nurse is preparing to administer tolterodine tartrate (Detrol LA)to a patient who has incontinence.Which symptom would be a contraindication for this drug?

Accepted Answer

A decrease in bowel sounds could signal the beginning of paralytic ileus.Detrol is contraindicated in patients with paralytic ileus.

Question 15

A patient who is intubated develops bradycardia because of vagal stimulation.Which medication will the nurse anticipate administering to treat this symptom?

Accepted Answer

Atropine is used to treat bradycardia caused by vagal stimulation.

Question 16

The nurse is caring for a patient in the post-anesthesia recovery unit.The nurse notes that the patient received atropine sulfate 2 mg 30 minutes prior to anesthesia induction.The patient has received 1,000 mL of intravenous fluids and has 700 mL of urine in the urinary catheter bag.The patient reports having a dry mouth.The nurse notes a heart rate of 82 beats per minute.What action will the nurse perform?

Accepted Answer

Atropine can cause urinary retention.The patient's urine output is less than the fluid intake,so the nurse should palpate the bladder to assess for distension.Dry mouth is an expected side effect and does not indicate dehydration.

Question 17

The nurse is preparing to administer bethanechol (Urecholine)to a patient who is experiencing urinary retention.The nurse notes that the patient has a blood pressure of 90/60 mm Hg and a heart rate of 98 beats per minute.The nurse will perform which action?

Accepted Answer

Side effects of this medication are a decrease in the pulse rate and vasodilation,which can exacerbate bradycardia and hypotension.The nurse should hold the drug and notify the provider.

Question 18

A patient who has irritable bowel syndrome would most likely receive which type of drug to treat this condition?

Accepted Answer

Anticholinergic drugs are used to treat peptic ulcers and intestinal spasticity because of their actions to decrease gastric secretions and gastrointestinal spasms.
