WGU D116 Pharmacy: Questions & Correct SolutionsOlanzapine and risperidone Right Ans - are used to treat other symptoms
that are associated with borderline personality disorder (BPD).
A patient is wheezing and short of breath. The nurse assesses a heart rate of
88 beats per minute, a respiratory rate of 24 breaths per minute, and a blood
pressure of 124/78 mm Hg. The prescriber orders a nonspecific beta-agonist
medication.
Besides evaluating the patient for a reduction in respiratory distress, the
nurse should monitor for which side effect? Right Ans - Tachycardia
Beta-agonists are used for asthma because of their beta2 effects on bronchial
smooth muscle, causing dilation. Beta1 effects cause tachycardia and
hypertension. Beta receptors do not exert effects on the bladder.
A patient is experiencing toxic side effects from atropine, including delirium
and hallucinations. Which medication should the provider administer?
Right Ans - Physostigmine is the drug of choice for treating poisoning from
atropine and other drugs that cause muscarinic blockade. Donepezil is used to
treat Alzheimer disease. Edrophonium is used to distinguish between a
myasthenic crisis and a cholinesterase inhibitor overdose. Neostigmine does
not cross the blood-brain barrier and would not effectively treat this patient's
central nervous system (CNS) symptoms.
donepezil Right Ans - used for dementia
A patient brought to the emergency department requires sutures. The
prescriber orders a local anesthetic with epinephrine. Right Ans -
epinephrine is ordered to allow a reduced dose of anesthetic
Epinephrine prolongs absorption of the anesthetic because it is an alpha1
agonist.
A patient who is taking oral contraceptives begins taking valproic acid for
seizures. After a week of therapy with valproic acid, the patient tells the nurse
that she is experiencing nausea. Right Ans - Ask the patient if she is taking
the valproic acid with food because taking the drug on an empty stomach can
cause gastrointestinal side effects
, A patient with cerebral palsy who has been receiving baclofen via gastrostomy
tube for three months is admitted to the hospital for evaluation of new-onset
seizures. Right Ans - Missed doses of baclofen.
Abrupt withdrawal of oral baclofen can cause visual hallucinations, paranoid
ideation, and seizures and should be considered when a patient develops
these symptoms. Seizures are not a symptom of baclofen toxicity.
A patient who has recurrent migraine headaches is prescribed sumatriptan.
Which aspect of this patient's history is of concern when taking this drug?
Right Ans - Coronary artery disease.
Correct! Serotonin receptor agonists can cause vasoconstriction and coronary
vasospasm and should not be given to patients with coronary artery disease,
current symptoms of angina, or uncontrolled hypertension. There is no
contraindication for asthma, diabetes, or renal disease.
A patient who has been taking a monoamine oxidase inhibitor (MAOI) for
depression for several months tells the provider that the medication has not
helped with symptoms. You plan to switch the patient to an SSRI.
What should you instruct the nurse to teach this patient? Right Ans - "Stop
taking the MAOI two weeks before starting the SSRI."
Correct! MAOIs increase serotonin receptor (5-HT) availability, thus greatly
increasing the risk of serotonin syndrome. MAOIs should be withdrawn at
least 14 days before an SSRI is started. An SSRI should never be given at the
same time as an MAOI. It is not necessary to wait five weeks before starting an
SSRI.
A patient is admitted to a hospital for treatment for first-time symptoms of
mania and is exhibiting euphoric mania.
Which medication should you order? Right Ans - Lithium
In almost all cases of mania, divalproex sodium is the drug of choice, except
for euphoric mania symptoms. Lithium is used to treat euphoric mania.
A patient presents to an emergency room complaining of palpitations and
irregular heartbeat. The advanced practice registered nurse (APRN) places
the patient on a cardiac monitor and observes atrial fibrillation. The APRN
orders dofetilide. Right Ans - Dofetilide is well absorbed (90%) both in the
presence and absence of food.
