Integumentary Medication

520. Salicylic acid is prescribed for a client with a diagnosis of psoriasis. The nurse monitors the client, knowing that which finding indicates the presence of systemic toxicity from this medication? 1. Tinnitus 2. Diarrhea 3. Constipation 4. Decreased respirations

520. 1 Rationale: Salicylic acid is absorbed readily through the skin, and systemic toxicity (salicylism) can result. Symptoms include tinnitus, dizziness, hyperpnea, and psychological disturbances. Constipation and diarrhea are not associated with salicylism. Test-Taking Strategy: Focus on the subject, systemic toxicity. Noting the name of the medication will assist in directing you to the correct option if you can recall the toxic effects that occur with acetylsalicylic acid (aspirin). Test-Taking Strategy: Focus on the subject, systemic toxicity. Noting the name of the medication will assist in directing you to the correct option if you can recall the toxic effects that occur with acetylsalicylic acid (aspirin).

521. The health education nurse provides instructions to a group of clients regarding measures that will assist in preventing skin cancer. Which instructions should the nurse provide? Select all that apply. 1. Sunscreen should be applied every 8 hours. 2. Use sunscreen when participating in outdoor activities. 3. Wear a hat, opaque clothing, and sunglasses when in the sun. 4. Avoid sun exposure in the late afternoon and early evening hours. 5. Examine your body monthly for any lesions that may be suspicious

521. 2, 3, 5 Rationale: The client should be instructed to avoid sun exposure between the hours of 10 AM and 4 PM. Sunscreen, a hat, opaque clothing, and sunglasses should be worn for outdoor activities. The client should be instructed to examine the body monthly for the appearance of any possible cancerous or any precancerous lesions. Sunscreen should be reapplied every 2 to 3 hours and after swimming or sweating; otherwise, the duration of protection is reduced. Test-Taking Strategy: Focus on the subject, measures to prevent skin cancer. Read each option carefully. Noting the time frames in options 1 and 4 will assist in eliminating these options.

522. Mafenide acetate (Sulfamylon) is prescribed for a client with a burn injury. When applying the medication, the client complains of local discomfort and burning. The nurse should take which most appropriate action? 1. Discontinue the medication. 2. Notify the health care provider. 3. Inform the client that this is expected. 4. Apply a thinner film than prescribed to the burn site.

522. 3 Rationale: Mafenide acetate is bacteriostatic for gram-negative and gram-positive organisms and is used to treat burns to reduce bacteria present in avascular tissues. The client should be informed that the medication will cause local discomfort and burning and that this is a normal reaction. Therefore options 1, 2, and 4 are incorrect Test-Taking Strategy: Note the strategic words most appropriate. Eliminate options 1 and 4 because it is not within the scope of nursing practice to alter or discontinue a medication therapy. Recalling that this is a normal expected occurrence will direct you to the correct option.

523. A burn client is receiving treatments of topical mafenide acetate (Sulfamylon) to the site of injury. The nurse monitors the client, knowing that which finding indicates that a systemic effect has occurred? 1. Hyperventilation 2. Local rash at the burn site 3. Elevated blood pressure 4. Local pain at the burn site

523. 1 Rationale: Mafenide acetate is a carbonic anhydrase inhibitor and can suppress renal excretion of acid, thereby causing acidosis. Clients receiving this treatment should be monitored for signs of an acid-base imbalance (hyperventilation). If this occurs, themedication will probably be discontinued for 1 to 2 days. Options 2 and 4 describe local rather than systemic effects. An elevated blood pressure may be expected from the pain that occurs with a burn injury. Test-Taking Strategy: Note the words systemic effect. Options 2 and 4 can be eliminated because they are comparable or alike and are local rather than systemic effects. From the remaining options, recall that the client in pain would likely have an elevated blood pressure. This should direct you to the correct option.

524. Isotretinoin (Amnesteem or Claravis) is prescribed for a client with severe acne. Before the administration of this medication, the nurse anticipates that which laboratory test will be prescribed? 1. Platelet count 2. Triglyceride level 3. Complete blood count 4. White blood cell count

524. 2 Rationale: Isotretinoin can elevate triglyceride levels. Blood triglyceride levels should be measured before treatment and periodically thereafter until the effect on the triglycerides has been evaluated. Options 1, 3, and 4 do not need to be monitored specifically during this treatment. Test-Taking Strategy: Eliminate options 3 and 4 first because they are comparable or alike in that a complete blood count also measures the white blood cell count. From the remaining options, recall that the medication can affect triglyceride levels in the client.

525. A client with severe acne is seen in the clinic and the health care provider (HCP) prescribes isotretinoin (Amnesteem or Claravis). The nurse reviews the client's medication record and would contact the HCP if the client is taking which medication? 1. Vitamin A 2. Digoxin (Lanoxin) 3. Furosemide (Lasix) 4. Phenytoin (Dilantin)

525. 1 Rationale: Isotretinoin is a metabolite of vitamin A and can produce generalized intensification of isotretinoin toxicity. Because of the potential for increased toxicity, vitamin A supplements should be discontinued before isotretinoin therapy. Options 2, 3, and 4 are not contraindicated with the use of isotretinoin. Test-Taking Strategy: Focus on the subject, the need to contact the HCP. Recalling that isotretinoin is a metabolite of vitamin A will direct you to the correct option.

526. The nurse is applying a topical corticosteroid to a client with eczema. The nurse should monitor for the potential for increased systemic absorption of the medication if the medication were being applied to which body area?1. Back 2. Axilla 3. Soles of the feet 4. Palms of the hands

526. 2 Rationale: Topical corticosteroids can be absorbed into the systemic circulation. Absorption is higher from regions where the skin is especially permeable (scalp, axilla, face, eyelids, neck, perineum, genitalia), and lower from regions where permeability is poor (back, palms, soles). Test-Taking Strategy: Focus on the subject, permeability and the potential for increased systemic absorption. Eliminate options 3 and 4 because these body areas are comparable or alike in terms of skin substance. From the remaining options, think about permeability of the skin area. This should direct you to the correct option

527. The clinic nurse is performing an admission assessment on a client and notes that the client is taking azelaic acid (Azelex). Because of the medication prescription, the nurse would suspect that the client is being treated for which condition? 1. Acne 2. Eczema 3. Hair loss 4. Herpes simplex

527. 1 Rationale: Azelaic acid is a topical medication used to treat mild to moderate acne. The acid appears to work by suppressing the growth of Propionibacterium acnes and by decreasing the proliferation of keratinocytes. Options 2, 3, and 4 are incorrect. Test-Taking Strategy: Focus on the subject, the purpose and use of azelaic acid. Focusing on the name of the medication will direct you to the correct option Test-Taking Strategy: Focus on the subject, the purpose and use of azelaic acid. Focusing on the name of the medication will direct you to the correct option.

528. Silver sulfadiazine (Silvadene, Thermazene, SSD cream) is prescribed for a client with a partial-thickness burn and the nurse provides teaching about the medication. Which statement made by the client indicates a need for further teaching about the treatments? 1. "The medication is an antibacterial." 2. "The medication will help heal the burn." 3. "The medication will permanently stain my skin." 4. "The medication should be applied directly to the wound."

528. 3 Rationale: Silver sulfadiazine (Silvadene, Thermazene, SSD cream) is an antibacterial that has a broad spectrum of activity against gram-negative bacteria, gram-positive bacteria, and yeast. It is applied directly to the wound to assist in healing. It does not stain the skin. Test-Taking Strategy: Note the strategic words need for further teaching. These words indicate a negative event query and ask you to select an option that is an incorrect statement. Recall the characteristics of this medication. Noting the words permanently stain in the correct option will direct you to this option.

529. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied at which times? 1. Immediately before swimming 2. 5 minutes before exposure to the sun3. Immediately before exposure to the sun 4. At least 30 minutes before exposure to the sun

529. 4 Rationale: Sunscreens are most effective when applied at least 30 minutes before exposure to the sun so that they can penetrate the skin. Allsunscreens should be reapplied after swimming or sweating Test-Taking Strategy: Knowledge that sunscreens need to penetrate the skin will assist in eliminating options 2 and 3. Next, noting the strategic words most effective will assist in directing you to the correct option
