Chapter 20 : Cholinergic Drugs Questions
Question 1 of 5
A patient is receiving a dose of edrophonium. The nurse recognizes that this drug is given to determine the diagnosis of which disease?
Correct Answer: C
Rationale: Edrophonium, an indirect-acting cholinergic drug, is commonly used to diagnose myasthenia gravis by improving muscle strength temporarily. It is not used to diagnose Parkinson's disease, multiple sclerosis, or Alzheimer's disease.
Question 2 of 5
A cholinergic drug is prescribed for a patient. The nurse checks the patient's medical history, knowing that this drug is contraindicated in which disorders?
Correct Answer: B,C,E,F
Rationale: Contraindications to the use of cholinergic drugs include gastrointestinal or genitourinary obstruction, bradycardia, hypotension, and chronic obstructive pulmonary disease due to potential exacerbation of these conditions. Bladder atony and Alzheimer's disease are potential indications for cholinergic drugs.
Question 3 of 5
A patient is receiving memantine 10 mg PO daily. The patient is unable to swallow pills, so an oral solution that contains 2 mg/mL is ordered. Identify how much will the patient receive per dose.
Correct Answer: 5 mL
Rationale: 2 mg : 1 mL :: 10 mg : x mL; (2 * x) = (1 * 10); 2x = 10; x = 5 mL.
Question 4 of 5
When monitoring a patient who is taking a cholinergic drug, the nurse will watch for which cardiovascular effect?
Correct Answer: A
Rationale: The cardiovascular effects of cholinergic drugs are decreased heart rate (bradycardia) and vasodilation. Palpitations and tachycardia are not effects of cholinergic drugs, and vasoconstriction is opposite to the vasodilation caused by these drugs.
Question 5 of 5
The nurse notes in a patient's medication history that the patient is taking pilocarpine. Based on this finding, the nurse interprets that the patient has which disorder?
Correct Answer: B
Rationale: Pilocarpine is a direct-acting cholinergic drug used topically to reduce intraocular pressure in patients with glaucoma. The other disorders are not indications for pilocarpine.
