A prescriber orders verapamil (Covera HS) for a patient who is taking digoxin
(Lanoxin) and warfarin. The nurse will expect the prescriber to _____ the dose of _____.
a.lower
Give this one a try later!
digoxin
b.increase; digoxin
c.lower; warfarin
d.increase; warfarin
;
a.lower; digoxin
Calcium channel blockers, such as verapamil, can increase levels of
digoxin, so patients taking these drugs may need to have their digoxin dose
reduced. Increasing the dose of digoxin can result in digoxin toxicity.
Verapamil does not affect warfarin levels.
,A patient who has begun using transdermal nitroglycerin for angina reports
occasional periods of tachycardia. The nurse will expect the prescriber to order:
a.digoxin (Lanoxin) to slow the heart rate.
b.immediate discontinuation of the nitroglycerin.
c.periods of rest when the heart rate increases.
d.verapamil as an adjunct to nitroglycerin therapy.

d.verapamil as an adjunct to nitroglycerin therapy.
Nitroglycerin lowers blood pressure by reducing venous return and dilating
the arterioles. The lowered blood pressure activates the baroreceptor
reflex, causing reflex tachycardia, which can increase cardiac demand and
negate the therapeutic effects of nitroglycerin. Treatment with a beta
blocker or verapamil suppresses the heart to slow the rate. Digoxin is not
recommended. Discontinuation of the nitroglycerin is not indicated. Resting
does not slow the heart when the baroreceptor reflex is the cause of the
tachycardia.
A patient newly diagnosed with asthma receives prescriptions for an inhaled
glucocorticoid and an inhaled beta2-adrenergic agonist. Which statement by the
patient indicates understanding of this medication regimen?
a."I should use the glucocorticoid as needed when symptoms flare."
b."I will need to use the beta2-adrenergic agonist drug daily."
c."The beta2-adrenergic agonist suppresses the synthesis of inflammatory mediators."
d."The glucocorticoid is used as prophylaxis to prevent exacerbations."

d."The glucocorticoid is used as prophylaxis to prevent exacerbations."
Inhaled glucocorticoids are used daily to prevent acute attacks. They are
not used PRN. The beta2-adrenergic agonist drugs should not be used
, daily; they are used to treat symptoms as needed. They do not suppress
mediators of inflammation.
A patient's provider has recommended a bulk-forming laxative for occasional
constipation. Which statement by the patient indicates understanding of the teaching
about this agent?
a."I can take this medication long term."
b."I should not take this drug if I have diverticulitis."
c."I should take each dose with a full glass of water."
d."This drug can cause severe diarrhea."
Give this one a try later!
c."I should take each dose with a full glass of water."
Bulk-forming laxatives provide insoluble substances that swell in water to
both soften and increase the size of the fecal mass. Patients should be
taught to take the dose with a full glass of water. Laxatives in general are
not recommended for long-term use. Bulk-forming laxatives are safe for
patients with diverticulitis. They are often used to treat diarrhea, because
they help form the fecal mass.
A patient with stable exertional angina has been receiving a beta blocker. Before
giving the drug, the nurse notes a resting heart rate of 55 beats per minute. Which is
an appropriate nursing action?
a.Administer the drug as ordered, because this is a desired effect.
b.Withhold the dose and notify the provider of the heart rate.
c.Request an order for a lower dose of the medication.
d.Request an order to change to another antianginal medication.

, a.Administer the drug as ordered, because this is a desired effect.
When beta blockers are used for anginal pain, the dosing goal is to reduce
the resting heart rate to 50 to 60 beats per minute. Because this heart rate
is a desired effect, there is no need to withhold the dose or notify the
provider. The dosage does not need to be lowered, because a heart rate of
55 beats per minute is a desired effect. There is no indication of a need to
change medications for this patient.
A patient will be taking amiodarone (Cordarone). Which baseline tests are necessary
before this medication is started? (Select all that apply.)
a.Chest radiograph and pulmonary function tests
b.Complete blood count with differential
c.Ophthalmologic examination
d.Renal function tests
e.Thyroid function tests

a.Chest radiograph and pulmonary function tests

e.Thyroid function tests
Amiodarone has many potential toxic side effects, including pulmonary
toxicity, ophthalmic effects, and thyroid toxicity, so these systems should
be evaluated at baseline and periodically while the patient is taking the
drug. A complete blood count is not indicated. Renal function tests are not
indicated.

cholestyramine (Questran). Which statement made by the patient demonstrates a
