A nursing instructor is describing a situation in which a client with tuberculosis periodically visits his primary health care provider and demonstrates taking his medication in front of the nurse. The instructor is describing which of the following?
- A. Initial phase of treatment
- B. Continuation phase of treatment
- C. Directly observed therapy
- D. Adherence evaluation
Correct Answer: C
Rationale: With directly observed therapy (DOT), the patient makes periodic visits to the office of the primary health care provider or the health clinic and takes the drug in the presence of the nurse. Nurses watch the patient swallow each dose of the medication treatment. In some cases, the nurse may travel to the patient's home, place of employment, or school to observe or administer medication. DOT can be used during the initial and/or continuation phase of treatment.

A nurse would expect to administer pyrazinamide cautiously to which clients? Select all that apply.
- A. Clients with diabetes
- B. Clients with hepatic impairment
- C. Clients with renal impairment
- D. Clients with hypertension

A client with diabetes who is taking an oral antidiabetic agent is diagnosed with tuberculosis and is prescribed rifampin. The nurse would instruct the client about which of the following?
- A. Increased risk for bleeding
- B. Greater risk for hepatotoxicity
- C. Increased blood glucose levels
- D. Risk for increased blood pressure
Correct Answer: C
Rationale: Rifampin interacts with oral hypoglycemic agents, leading to a decrease in the effectiveness of the oral hypoglycemic agent, thus increasing blood glucose levels. An increased risk for bleeding occurs when rifampin is given with oral anticoagulants. An increased risk of hepatotoxicity occurs when rifampin is given with isoniazid. When verapamil is given with rifampin, the effectiveness of verapamil is decreased, leading to increased blood pressure levels.
A nurse is caring for a patient undergoing the second phase of standard TB treatment. The nurse knows that which of the following combinations of drugs needs to be administered to the client?
- A. Pyrazinamide and dapsone
- B. Rifampin and pyrazinamide
- C. Rifampin and isoniazid
- D. Dapsone and isoniazid
Correct Answer: C
Rationale: The nurse knows that a combination of rifampin and isoniazid drugs should be used during the second phase of standard treatment. Isoniazid, rifampin, and pyrazinamide are not used together as combination drugs in the second phase of standard treatment. Dapsone is used for leprosy and cannot be used in combination with isoniazid or any other drug for TB.
A nursing student is reviewing information about tuberculosis therapy. The student demonstrates understanding of the information when identifying which of the following as true about the initial phase of tuberculosis therapy? Select all that apply.
- A. Drugs are used to kill the rapidly multiplying M tuberculosis.
- B. Drugs are used to prevent drug resistance.
- C. The initial phase lasts approximately 6 to 9 months.
- D. The initial phase lasts approximately 2 months.
- E. The initial phase lasts approximately 4 months.
Correct Answer: A,B,D
Rationale: During the initial phase, which lasts approximately 2 months, drugs are used to kill the rapidly multiplying M. tuberculosis and to prevent drug resistance. The continuing phase lasts approximately 4 months and the entire treatment spans 6 to 9 months.
An HIV-positive patient is in a continuing phase of TB. The patient has completed the initial phase of the treatment program. In the continuing phase, the patient has shown no positive sputum results for 6 months. The nurse knows that under what circumstances does the treatment in the second phase last for 4 months or more?
- A. Positive sputum culture after the completion of initial treatment
- B. Inclusion of pyrazinamide in the initial treatment
- C. Following the same eating habits in the continuing phase
- D. Nausea or vomiting after completing the initial treatment
Correct Answer: A
Rationale: Positive sputum culture after the completion of initial treatment leads to treatment in the second phase lasting for 4 to 7 months. Following the same eating habits (diet) will not cause treatment in the second phase to last for 4 months or more, nor will nausea or vomiting occurring after completing the initial treatment. Noninclusion of pyrazinamide in the initial treatment leads to the second phase lasting for 4 to 7 months or more.
