The nurse is obtaining a client's drug history prior to initiating therapy with gentamicin (Garamycin). The client takes furosemide (Lasix). Based on this information, the nurse identifies the client is at increased risk for:
 
  1. nephrotoxicity.
  2. ototoxicity.
  3. pseudomembranous colitis.
  4. photosensitivity.

Question 2

A clinic nurse is teaching a group of teens taking tetracycline for acne. Which teaching points should take priority?
 
  Standard Text: Select all that apply.
  1. Take tetracycline on an empty stomach to increase absorption.
  2. Tetracycline may cause photosensitivity, making the skin susceptible to sunburn.
  3. Tetracycline may cause vaginal yeast infection in women who are using oral contraceptives.
  4. Tetracycline is one of the safest antibiotics to take during pregnancy.
  5. Tetracycline commonly causes diarrhea. The client should start a clear liquid diet and slowly resume a normal diet.

Answer to Question 1

Correct Answer: 2
Rationale 1: The risk for nephrotoxicity is increased if nephrotoxic drugs are prescribed concurrently.
Rationale 2: Concurrent use of more than one ototoxic drug increases the risk of hearing impairment.
Rationale 3: Pseudomembranous colitis is a serious adverse effect associated with tetracycline.
Rationale 4: Photosensitivity is associated with protein synthesis inhibitors, but not with calcium channel blockers or salicylates.
Global Rationale: Concurrent use of more than one ototoxic drug increases the risk of hearing impairment.
The risk for nephrotoxicity is increased if nephrotoxic drugs are prescribed concurrently. Pseudomembranous colitis is a serious adverse effect associated with tetracycline. Photosensitivity is associated with protein synthesis inhibitors, but is not potentiated by addition of furosemide.

Answer to Question 2

Correct Answer: 1,2,3
Rationale 1: Food, especially milk or diary products, decreases the absorption of tetracycline.
Rationale 2: Tetracycline does cause photosensitivity that makes the skin more susceptible to sunburn.
Rationale 3: Women on oral contraceptives and tetracycline have a higher incidence of vaginal yeast infections.
Rationale 4: Tetracycline is contraindicated in pregnancy because it can cause brown stains on the baby's teeth.
Rationale 5: Tetracycline-induced diarrhea is common, but the possibility of pseudomembranous colitis must be promptly ruled out.
Global Rationale: Adverse effects of tetracycline include photosensitivity and a higher incidence of vaginal yeast infections when taken concurrently with oral contraceptives. Food decreases absorption. Diarrhea is a common adverse effect, but should be assessed for the presence of pseudomembranous colitis. Tetracycline is contraindicated in pregnancy because it can cause brown stains on the baby's teeth.
