23 terms K_Copeland5Preview Pharma 98 terms Gdu The nurse is administering isoproterenol, a beta1 and beta2 agonist. The nurse expects the patient to show which effects of this drug? (Select all that apply.)

• Increased heart rate
• Excessive drowsiness
• Increased force of heart contraction
• Decreased cardiac output
• Bronchial dilation
• Decreased glucose levels

A, C, E

A nurse is preparing to give a drug that stimulates the parasympathetic nervous system. Which patient response is an expected outcome of this drug?

• Wheezing decreases due to bronchodilation.
• Heart rate decreases to 60 beats per minute.
• Diarrhea stool count decreases.
• Oxygenation improves because of bronchodilation.

B A patient is experiencing symptoms of the fight-or-flight response. Which autonomic process orchestrates this response?

• Stimulation of the sympathetic system
• Stimulation of the predominant tone of the organs
• Stimulation of the baroreceptor reflex
• Stimulation of the parasympathetic system

A

The nurse knows that which neurotransmitter is most commonly found at the synapses of the peripheral nervous system?

• Norepinephrine
• Epinephrine
• Dopamine
• Acetylcholine

D A nurse is preparing to give a medication that stimulates the beta2 receptors. What response will the nurse expect from this drug?

• Increased peristalsis
• Constriction of the pupil
• Hypoglycemia
• Bronchodilation

D A nurse gives a medication that inhibits acetylcholinesterase. How would this drug affect autonomic activity?

• Parasympathetic activity would increase.
• Parasympathetic signals would be depressed.
• Sympathetic activity would increase.
• Respiratory centers would be depressed.

A Which organs are controlled primarily by the parasympathetic system? (Select all that apply.)

• Gastrointestinal tract
• Respiratory tract
• Cardiovascular system
• Skin
• Salivary glands

All except C Which receptors below are considered adrenergic receptors? (Select all that apply.)

• Alpha1
• Beta2
• Dopamine
• Muscarinic1
• Beta1
• Alpha2

All except D A nurse is preparing to give bethanechol (Urecholine).What is an expected outcome of this drug?

• Nondistended bladder
• Increased heart rate and blood pressure
• Improved pulse oximetry reading
• Relief of cardiac rhythm problems

A

A nurse prepares to administer a new prescription for bethanechol (Urecholine). Which information in the patient's history should prompt the nurse to consult with the prescriber before giving the drug?

• Constipation
• Hypertension
• Psoriasis
• Asthma

D Which symptom is the most indicative of muscarinic poisoning?

• Constipation
• Heart rate of 140 beats per minute
• Blood pressure of 180/110 mm Hg
• Blurred vision

D Which label most aptly describes the drug atropine (Sal- Tropine)?

• Cholinergic
• Parasympatholytic
• Muscarinic agonist
• Parasympathomimetic

B The nurse is caring for a patient receiving atropine (Sal- Tropine). Which is a therapeutic indication for giving this drug?

• Use as a preanesthesia medication
• Treatment of tachycardias
• Prevention of urinary retention
• Reduction of intraocular pressure in glaucoma

A The nurse is caring for a group of patients who are all receiving anticholinergic drugs. In which patient is an anticholinergic drug contraindicated?

• A 60-year-old woman with an overactive bladder

(OAB)

• A 72-year-old man with glaucoma
• A 45-year-old woman with peptic ulcer disease (PUD)
• A 26-year-old man being prepared for surgery today

B

Antimuscarinic poisoning can result from overdose of antihistamines, phenothiazines, and tricyclic antidepressants. Differential diagnosis is important, because antimuscarinic poisoning resembles which other condition?

• Epilepsy
• Diabetic coma
• Meningitis
• Psychosis

D The nurse is preparing to give neostigmine (Prostigmin).What best describes the action of this drug?

• It inhibits acetylcholine at all cholinergic synapses.
• It prevents inactivation of acetylcholine.
• It prevents activation of muscarinic receptors.
• It stimulates activation of adrenergic receptors.

B What best describes the rationale for using neostigmine (Prostigmin) in the treatment of myasthenia gravis?

• It promotes neuromuscular blockade in the periphery.
• It promotes emptying of the bladder and sphincter

relaxation.

• It reduces intraocular pressure and protects the optic

nerve.

• It increases the force of skeletal muscle contraction.

D The nurse is caring for a patient with a suspected overdose of pancuronium, which was used during surgery. Which drug does the nurse anticipate will be used as a reversal agent?

• Neostigmine (Prostigmin)
• Atropine (Sal-Tropine)
• Pralidoxime (DuoDote)
• Dobutamine (Dobutrex)

A The nurse is caring for a patient with myasthenia gravis who is beginning a new prescription of neostigmine (Prostigmin), 75 mg PO twice daily. What is the most important initial nursing action?

• Obtain a measurement of the plasma level of

neostigmine

• Teach the patient to wear a Medic Alert bracelet
• Assess the patient's ability to swallow
• Check the patient's deep tendon reflexes (DTRs)
