,A client has been taking isoniazid (INH) for 2 months. The client complains to a nurse about
V V V V V V V V V V V V V V V V




numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is
V V V V V V V V V V V V V V




experiencing:
V




1. Hypercalcemia
2. Peripheral neuritis V




3. Small blood vessel spasm
V V V




4. Impaired peripheral circulation - answer>>>2. Peripheral neuritis
V V V V V V




Rationale:A common side effect of the TB drug INH is peripheral neuritis. This is manifested by
V V V V V V V V V V V V V V V




numbness, tingling, and paresthesia in the extremities. This side effect can be minimized by
V V V V V V V V V V V V V V




pyridoxine (vitamin B6) intake. Options 1, 3, and 4 are incorrect.

A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the
V V V V V V V V V V V V V V V V V V




client to:
V V




1. Drink alcohol in small amounts only.
V V V V V




2. Report yellow eyes or skin immediately.
V V V V V




3. Increase intake of Swiss or aged cheeses. 4. Avoid vitamin supplements during therapy. -
V V V V V V V V V V V V V




answer>>>2. Report yellow eyes or skin immediately.
V V V V V V V




Rationale:
INH is hepatotoxic, and therefore the client is taught to report signs and symptoms of hepatitis
V V V V V V V V V V V V V V V




Vimmediately (which include yellow skin and sclera). For the same reason, alcohol should be
V V V V V V V V V V V V V




Vavoided during therapy. The client should avoid intake of Swiss cheese, fish such as tuna, and
V V V V V V V V V V V V V V V




Vfoods containing tyramine because they may cause a reaction characterized by redness and
V V V V V V V V V V V V




Vitching of the skin, flushing, sweating, tachycardia, headache, or lightheadedness. The client can
V V V V V V V V V V V V




Vavoid developing peripheral neuritis by increasing the intake of pyridoxine (vitamin B6) during the
V V V V V V V V V V V V V




Vcourse of INH therapy for TB.

A client has been started on long-term therapy with rifampin (Rifadin). A nurse teaches the client
V V V V V V V V V V V V V V V




that the medication:
V V V

,1. Should always be taken with food or antacids V V V V V V V




2. Should be double-dosed if one dose is forgotten V V V V V V V




3. Causes orange discoloration of sweat, tears, urine, and feces
V V V V V V V V




4. May be discontinued independently if symptoms are gone in 3 months - answer>>>3. Causes
V V V V V V V V V V V V V




orange discoloration of sweat, tears, urine, and feces
V V V V V V V V




Rationale:
Rifampin should be taken exactly as directed as part of TB therapy. Doses should not be doubled
V V V V V V V V V V V V V V V V




or skipped. The client should not stop therapy until directed to do so by a health care provider.
V V V V V V V V V V V V V V V V V V




The medication should be administered on an empty stomach unless it causes gastrointestinal
V V V V V V V V V V V V V




upset, and then it may be taken with food. Antacids, if prescribed, should be taken at least 1 hour
V V V V V V V V V V V V V V V V V V V




before the medication. Rifampin causes orange-red discoloration of body secretions and will
V V V V V V V V V V V V




permanently stain soft contact lenses.
V V V V V




A nurse has given a client taking ethambutol (Myambutol) information about the medication. The
V V V V V V V V V V V V V




nurse determines that the client understands the instructions if the client states that he or she
V V V V V V V V V V V V V V V V




will immediately report:
V V V




1. Impaired sense of hearing V V V




2. Problems with visual acuity V V V




3. Gastrointestinal (GI) side effects V V V




4. Orange-red discoloration of body secretions - answer>>>2. Problems with visual acuity
V V V V V V V V V V




Rationale:
Ethambutol causes optic neuritis, which decreases visual acuity and the ability to discriminate
V V V V V V V V V V V V




between the colors red and green. This poses a potential safety hazard when a client is driving a
V V V V V V V V V V V V V V V V V V




motor vehicle. The client is taught to report this symptom immediately. The client is also taught to
V V V V V V V V V V V V V V V V V




take the medication with food if GI upset occurs. Impaired hearing results from antitubercular
V V V V V V V V V V V V V V




therapy with streptomycin. Orange-red discoloration of secretions occurs with rifampin (Rifadin).
V V V V V V V V V V V




Cycloserine (Seromycin) is added to the medication regimen for a client with tuberculosis. Which
V V V V V V V V V V V V V




Vof the following would the nurse include in the client-teaching plan regarding this medication?1
V V V V V V V V V V V V V




. To take the medication before meals
V V V V V V




2. To return to the clinic weekly for serum drug-level testing
V V V V V V V V V




3. It is not necessary to call the health care provider (HCP) if a skin rash occurs.
V V V V V V V V V V V V V V V




4. It is not necessary to restrict alcohol intake with this medication. - answer>>>2. To return to the
V V V V V V V V V V V V V V V V




Vclinic weekly for serum drug-level testing
V V V V V

, Rationale:
Cycloserine (Seromycin) is an antitubercular medication that requires weekly serum drug level
V V V V V V V V V V V




determinations to monitor for the potential of neurotoxicity. Serum drug levels lower than 30
V V V V V V V V V V V V V V




mcg/mL reduce the incidence of neurotoxicity. The medication must be taken after meals to
V V V V V V V V V V V V V V




prevent gastrointestinal irritation. The client must be instructed to notify the HCP if a skin rash or
V V V V V V V V V V V V V V V V V




signs of central nervous system toxicity are noted. Alcohol must be avoided because it increases
V V V V V V V V V V V V V V V




the risk of seizure activity.
V V V V V




A client with tuberculosis is being started on antituberculosis therapy with isoniazid (INH). Before
V V V V V V V V V V V V V




giving the client the first dose, a nurse ensures that which of the following baseline studies has
V V V V V V V V V V V V V V V V V




been completed?
V V




1. Electrolyte levels V




2. Coagulation times V




3. Liver enzyme levels V V




4. Serum creatinine level - answer>>>3. Liver enzyme levels
V V V V V V V




Rationale:
INH therapy can cause an elevation of hepatic enzyme levels and hepatitis. Therefore, liver
V V V V V V V V V V V V V




Venzyme levels are monitored when therapy is initiated and during the first 3 months of therapy.
V V V V V V V V V V V V V V V




VThey may be monitored longer in the client who is greater than age 50 or abuses alcohol.

disease and tuberculosis. The nurse monitors for which side effects of the medication? Select all
V V V V V V V V V V V V V V V




that apply.
V V




1. Signs of hepatitis V V




2. Flu-like syndrome V




3. Low neutrophil count V V




4. Vitamin B6 deficiency V V




5. Ocular pain or blurred vision V V V V




6. Tingling and numbness of the fingers - answer>>>1. Signs of hepatitis
