Chapter 41 : Antitubercular Drugs Questions
Question 1 of 5
The nurse is preparing to administer morning medications to a patient who has been newly diagnosed with tuberculosis. The patient asks, 'Why do I have to take so many different drugs?' Which response by the nurse is correct?
Correct Answer: B
Rationale: Recent treatment guidelines recommend the use of multiple medications because of the increasing presence of resistance. The other options are incorrect.
Question 2 of 5
A patient newly diagnosed with tuberculosis (TB) has been taking antitubercular drugs for 1 week calls the clinic and is very upset. He says, 'My urine is dark orange! What's wrong with me?' Which response by the nurse is correct?
Correct Answer: D
Rationale: Rifampin, one of the first-line drugs for TB, causes a red-orange-brown discoloration of urine, tears, sweat, and sputum. Patients need to be warned about this side effect. The other options are incorrect.
Question 3 of 5
The nurse is providing patient teaching for a patient who is starting antitubercular drug therapy. Which of these statements should be included? (Select all that apply.)
Correct Answer: B,C,E,G
Rationale: Medications for tuberculosis must be taken on a consistent schedule to maintain blood levels. Because of potential liver toxicity, patients on this drug therapy must not drink alcohol. Burning or tingling in the fingers or toes may indicate that peripheral neuropathy is developing, and the prescriber needs to be notified immediately. A second form of birth control must be used because antitubercular drug therapy makes oral contraceptives ineffective. Medication therapy for tuberculosis may last up to 24 months, long after symptoms disappear. Discoloration of the urine is an expected adverse effect, and patients need to be warned about it beforehand. Compliance with antitubercular drug therapy is key, so if symptoms become severe, the prescriber should be contacted for an adjustment of the drug therapy; the medication must not be stopped.
Question 4 of 5
The nurse is discussing adverse effects of antitubercular drugs with a patient who has active tuberculosis. Which potential adverse effect of antitubercular drug therapy should the patient report to the prescriber?
Correct Answer: D
Rationale: Patients on antitubercular therapy should report experiencing numbness and tingling of extremities, which may indicate peripheral neuropathy. Some drugs may color the urine, stool, and other body secretions reddish-orange, but this is not an effect that needs to be reported. Patients need to be informed of this expected effect. The other options are incorrect.
Question 5 of 5
A patient who has been taking isoniazid has a new prescription for pyridoxine. She is wondering why she needs this medication. The nurse explains that pyridoxine is often given concurrently with the isoniazid to prevent which condition?
Correct Answer: C
Rationale: Pyridoxine (vitamin B6) may be beneficial for isoniazid-induced peripheral neuropathy. The other options are incorrect.
