  • instruct patients to avoid antacids and to take the drug on an empty stomach (1hr before or 2hr after meals) to prevent slowing of drug absorption in the GI tract
  • teach patients to take a daily multi-vitamin that contains the B-complex vitamins while on this drug because the drug can deplete the body of this vitamin
  • remind patients to avoid alcoholic beverages whle on this drug because the liver-damaging effects of this drug are potentiated by alcohol
  • tell patients to report darkering of the urine, a yellow appearance to the skin or white of the eyes, and an increased tendency to bruise or bleed, which are signs and symptoms of liver toxicity or failure

58
Q

Nursing Implications for Rifampin

A
  • warn patients to expect an orange- reddish staining of the skin and urine and all other secretions to have a reddish- orange tinge; also, soft contact lenses will become permanently stained because knowing the expected side effects decreases anxiety when they appear

  • remind patients to avoid alcoholic beverages while on this drug because the liver- damaging effects of this drug are potentiated by alcohol
  • tell patients to report darkening of the urine, a yellow appearance to the skin or whites of the eyes, and an increased tendency to bruise or bleed, which are signs and symptoms of liver toxicity or failure
  • ask patients about all other drugs in use because this drug interacts with many other drugs
59
Q

pyrazinamide

antitububerculotic

60
Q
  • can effectively kill organisms residing within the very acidic environment of macrophages (which is where the tuberculosis bacilius sequesters)
  • available only in combinations with other anti-TB drugs
A

pyrazinamide

61
Q

Nursing Implications for Pyrazinamide

A
  • ask patient if they have ever had gout because the drug increases uric acid formation and will make gout worse
  • instruct patients to drink at least 8 ounces of water when taking this tablet and to increase fluid intake to prevent uric acid from precipitating, making gout or kidney problems worse
  • teach patients to wear protective clothing, a hat, and sunscreen when going outdoors in the sunlight because the drug causes photosensitivity and greatly increases the risk for sunburn
  • remind patients to avoid alcoholic beverages while on this drug because the live- damaing effects of this drug are potentiated by alcohol

62
Q

ethambutol

A

antitubercular

Q
  • inhibits bacterial RNA synthesis, thus suppressing bacterial growth
  • slow acting and bacteriostatic rather than bactericidal; thys it must be used in combination with other anti-TB drugs
A

ethambutol

64
Q

Nursing Implications for Ethambutol

A
  • instruct patients to report any changes in vision, such as reduced color vision, blurred vision, or reduced visual fields, immediately to his or her primary health care provider because the drug can cause optic neuritis, especially at high doses, and can lead to blindness. Minor eye problems are usually reversed when the drug is stopped
  • remind patients to avoid alcoholic beverages while on this drug because the drug induces severe nausea and vomiting when alcohol is ingested
  • ask patients if they have ever had gout because the drug increases uric acid formation and will make gout worse.
  • instruct patients to drink at least 8 ounces of water when taking this drug and to increase fluid intake to prevent uric acid from precipitating, making gout or kidney problems worse
