Chapter 56 : Dermatologic Drugs Questions
Question 1 of 5
A female patient will be starting therapy with oral isotretinoin as part of treatment for severe acne, and the nurse is providing teaching. Which teaching point will the nurse include in her teaching plan about isotretinoin?
Correct Answer: A
Rationale: It is now required that at least two contraceptive methods be used by sexually active women during and for 1 month after completion of therapy with isotretinoin.
Question 2 of 5
A patient is admitted to the hospital for possible septicemia. He has a large pressure ulcer on his heel that is open and includes necrotic tissue. However, his prothrombin time/international normalized ratio (PT/INR) values are too high to permit surgical debridement at this time. The nurse expects that which wound-care product will be used to treat the wound?
Correct Answer: D
Rationale: Because this patient has an elevated PT/INR, he cannot receive surgical debridement because of concerns about excessive bleeding. Collagenase is useful for patients taking anticoagulants and for those in whom surgery is contraindicated; it selectively removes necrotic tissue but does not harm normal tissue.
Question 3 of 5
The nurse is reviewing laboratory results for a patient and notes that the patient has positive results for nasal colonization by methicillin-resistant Staphylococcus aureus (MRSA). The nurse anticipates an order for which medication?
Correct Answer: B
Rationale: Mupirocin (Bactroban) is used on the skin for treatment of staphylococcal and streptococcal impetigo. It is used topically and intranasally to treat nasal colonization by MRSA; however, MRSA is becoming increasingly resistant to the drug.
Question 4 of 5
The nurse is reviewing the medical record of a patient who is to receive wound care with topical silver sulfadiazine. Which finding, if noted, would be a potential contraindication?
Correct Answer: B
Rationale: Patients with allergies to sulfonamide drugs must not receive silver sulfadiazine.
Question 5 of 5
A patient is considering taking oral aloe supplements and asks the nurse about potential problems with this therapy. Which statement by the nurse is correct?
Correct Answer: B
Rationale: The dried juice of the leaves of the aloe plant contains anthranoids, which give aloe a laxative effect when taken orally. The topical application of the plant juice has been known for years to help the healing of wounds. Common adverse effects include diarrhea, nephritis, abdominal pain, and dermatitis when used topically.
