A. C.
A patient is receiving bethanechol (Urecholine). The nurse realizes that the action of this drug is to treat which condition? a.Glaucoma b.Urinary retention c.Delayed gastric emptying d.Gastroesophageal reflux disease
B.
The nurse realizes that cholinergic agonists mimic which parasympathetic neurotransmitter? a.dopamine b.acetylcholine c.cholinesterase d.monoamine oxidase
B.
Which type of medication is bethanechol? A. Anticholinergic B. Cholinergic Agonist C. Cholinesterase inhibitor D. Sympatholytic
B.
A patient is prescribed scopolamine. It is most important for the nurse to assess the patient for a history of which condition? A. Diabetes mellitus B. Glaucoma C. Allergy to penicillin D. Gastric ulcer
B. Because anticholinergic drugs can increase intraocular pressure, they should not be administered to patients diagnosed with glaucoma
A nurse has just administered atropine to a patient. It is most important for the nurse to assess the patient for the development of which effect? a.Nausea b.Tachycardia c.Rales d.Hypotension
B. It is most important to monitor the heart rate for tachycardia after atropine is given. Atropine may be given without regard to meals. Rales would not be expected because atropine dries secretions rather than increase them. Hypertension is a more likely response than orthostatic hypotension.

B. Dilate the pupils
How does bethanechol work in the body? A. inhibits muscarinic receptors B. inhibits nicotinic receptors C. Stimulates muscarinic receptors D. stimulates nicotinic receptors
C.

C.
The patient has been prescribed bethanechol and asks the nurse how it works. What is the nurses's best response? A. "This drug decreases bladder tone." B. "This drug inhibits bladder contraction." C. "This drug promotes contraction of the bladder." D. "This drug stimulates urine production."
C.

Which medication treats myasthenia gravis by increasing muscle strength? A. Bethanechol B. Edrophonium chloride C. Neostigmine bromide D. Pilocarpine
C.
A patient received atropine as a preoperative medication 30 minutes ago. The nurse evaluates the medication as effective if the patient states... A. "I feel like I need to throw up." B. "I need to urinate." C. "My mouth feels dry." D. "I have a headache."
C. Atropine is useful primarily (1) as a preoperative medication to decrease salivary secretions and (2) as an agent to increase heart rate when bradycardia is present.
A patient has received atropine. It is most important for the nurse to assess the patient for which effect? A. Anxiety B. Constipation C. Urinary Retention D. Impaired oral mucous membrane
C. Urinary retention is the highest priority because it is more serious to systemic homeostasis than anxiety, constipation, or a dry mouth.
