Question 1

A patient has been prescribed an anti-TB therapy.What should the nurse say about this medication to the patient? (Select all that apply.)&#10;A)&#34;Take the medications until the symptoms disappear.&#34;&#10;B)&#34;Take the medications at the same time every day.&#34;&#10;C)&#34;You are considered contagious for most of the illness and must take precautions to prevent spreading the disease.&#34;&#10;D)&#34;The medications may be stopped if you have severe adverse effects.&#34;&#10;E)&#34;Alcoholic beverages should be avoided while on this therapy.&#34;&#10;F)&#34;If you notice reddish-brown or reddish-orange urine, stop the drug and contact your doctor right away.&#34;&#10;G)&#34;If you experience a burning or tingling in your fingers or toes, report this to your physician immediately.&#34;&#10;H)&#34;Oral contraceptives may not work while on these drugs, so you will need to use another form of birth control.&#34;

Accepted Answer

"Take the medications at the same time every day," "Alcoholic beverages should be avoided while on this therapy," "If you experience a burning or tingling in your fingers or toes,report this to your physician immediately," and "Oral contraceptives may not work while on these drugs,so you will need to use another form of birth control" are all appropriate teaching statements for antitubercular drug therapy.A second form of birth control should be used because antitubercular drug therapy will make oral contraceptives ineffective.
Medication therapy for TB may last up to 24 months,long after the symptoms disappear,and patients are infectious during only the early part of the treatment.Patient adherence to antitubercular drug therapy is key; if symptoms become severe,the prescriber should be contacted for an adjustment of drug therapy.The medication should not be stopped.Because of potential liver toxicity,patients on this drug therapy should not drink alcohol.Discoloration of the urine is an expected adverse effect,which the patient should be warned about.

Question 2

Patients taking isoniazid (Isotamine)should watch for and report which potential adverse effect(s)?&#10;A)Rash&#10;B)Headache and nervousness&#10;C)Insomnia&#10;D)Numbness and tingling of extremities

Accepted Answer

Patients on isoniazid therapy should report numbness and tingling of extremities.Rash,headache,nervousness,and insomnia are not adverse effects of isoniazid.Headache and insomnia are adverse effects of levofloxacin and some of the other antibiotics used to treat tuberculosis.

Question 3

What indicates a patient's therapeutic response to antitubercular drugs?&#10;A)Cessation of the chronic cough&#10;B)Two consecutive negative purified protein derivative tuberculin skin test results over 2 months&#10;C)An increased tolerance to the medication therapy and fewer reports of adverse effects&#10;D)A decrease in symptoms of tuberculosis (TB) and improved chest X-rays and sputum cultures

Accepted Answer

A therapeutic response to the therapy is indicated by a decrease in symptoms of TB,supported by improved chest X-rays,sputum cultures and sensitivities.

Question 4

Which has a significant drug interaction with isoniazid (Isotamine)?&#10;A)Alcohol&#10;B)Nicotine&#10;C)Antacids&#10;D)Laxatives

Accepted Answer

Antacids reduce the absorption of isoniazid and thus reduce serum levels.

Question 5

What information is the nurse to provide to a woman who is beginning rifampin therapy and is currently taking an oral contraceptive?&#10;A)There is an increased risk of thrombophlebitis.&#10;B)A higher dose of rifampin will be necessary.&#10;C)Oral contraceptives are ineffective while the patient is taking rifampin.&#10;D)The incidence of adverse effects is greater when the two drugs are taken together.

Accepted Answer

Women taking oral contraceptives and rifampin should be counselled on other forms of birth control because of the impaired effectiveness of the oral contraceptives during concurrent use of rifampin.

Question 6

Family members exposed to a patient with active TB may require prophylactic drug therapy.How long do they need to take this therapy?&#10;A)6 months&#10;B)9 months&#10;C)18 months&#10;D)24 months

Accepted Answer

Accepted Answer

Drug therapy often lasts for up to 24 months if patient adherence has been maintained.

Question 9

Which is the reason for using multidrug therapy in the treatment of TB?&#10;A)Multiple drugs are required to eradicate TB.&#10;B)The use of multiple medications reduces the chance of TB becoming drug resistant.&#10;C)Multidrug therapy will have a faster effect than will single-drug therapy.&#10;D)Using multidrug therapy enhances the effect of each drug.

Accepted Answer

The use of multiple medications reduces the possibility of the organism becoming drug resistant.
