Chapter 41 : Antitubercular Drugs Questions
Question 1 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 2 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.
Question 3 of 5
The nurse will assess the patient for which potential contraindication to antitubercular therapy?
Correct Answer: D
Rationale: Results of liver function studies (e.g., bilirubin level, liver enzyme levels) need to be assessed because isoniazid and rifampin may cause hepatic impairment; severe liver dysfunction is a contraindication to these drugs. The other options are incorrect.
Question 4 of 5
When monitoring patients on antitubercular drug therapy, the nurse knows that which drug may cause a decrease in visual acuity?
Correct Answer: C
Rationale: Ethambutol may cause a decrease in visual acuity or even blindness resulting from retrobulbar neuritis. The other options are incorrect.
Question 5 of 5
A patient has been taking antitubercular therapy for 3 months. The nurse will assess for what findings that indicate a therapeutic response to the drug therapy?
Correct Answer: D
Rationale: A therapeutic response to antitubercular therapy is manifested by a decrease in the symptoms of tuberculosis, such as cough and fever, and by weight gain. The results of laboratory studies (culture and sensitivity tests) and the chest radiographic findings will be used to confirm the clinical findings of resolution of the infection.
