Nokea
A nurse is to administer mafenide to a client. The nurse would be alert for which of the following?
- A. Rash, itching, or other allergic reactions
- B. Crystals in the urine sample
- C. Inflammation of the mouth
- D. Loss of appetite
Correct Answer: A
Rationale: The nurse should assess for allergic reactions such as rash, itching, edema, and urticaria when administering mafenide. Topical sulfonamides like mafenide do not cause crystalluria, inflammation of the mouth, or loss of appetite.

A nurse is preparing a plan of care for an older adult client who is receiving sulfonamide therapy. Which of the following would the nurse include in the plan of care to reduce the likelihood of causing renal damage? Select all that apply.
- A. Administer sulfonamides once daily.
- B. Increase fluid intake up to 2000 mL if tolerated.
- C. Use sulfonamides cautiously in clients with renal impairment.
- D. Administer the dose intravenously instead of orally.
- E. Ask the prescriber to change the medication ordered
Correct Answer: B,C
Rationale: Older adults experience a decline in renal function with aging. Therefore, sulfonamides must be used cautiously in older clients. In addition, increasing fluid intake up to 2000 mL daily can decrease the likelihood of causing renal damage in older clients. The drug is administered throughout the day, not as a once-daily dose. Sulfonamides can affect renal function regardless of the route administered. Asking the prescriber to change the medication ordered may be appropriate but is not necessary as long as the drug is administered cautiously and the client is monitored closely.
A nurse is caring for a client with burns. The client is prescribed topical silver sulfadiazine. The nurse would be alert for which of the following?
- A. Facial edema
- B. Skin necrosis
- C. Headache
- D. Rash
Correct Answer: B
Rationale: Skin necrosis is an adverse effect of silver sulfadiazine that the nurse should be alert for. Facial edema and rash are adverse effects of mafenide, used for second- and third-degree burns. Headache is an adverse effect of sulfadiazine, used for urinary tract infection.
When developing the plan of care for a client receiving sulfonamides for treatment of a urinary tract infection, the nurse identifies actions for encouraging fluid intake and monitoring intake and output based on which nursing diagnosis?
- A. Risk for Fluid Imbalance
- B. Impaired Urinary Elimination
- C. Risk for Ineffective Renal Perfusion
- D. Stress Incontinence
Correct Answer: B
Rationale: A client with a urinary tract infection already is experiencing an alteration in urinary elimination. Because one adverse effect of the sulfonamide drugs is altered elimination patterns, it is important to help the client maintain adequate fluid intake and output. The nurse would encourage clients to increase fluid intake to 2000 mL or more per day to prevent crystalluria and stones (calculi) forming in the genitourinary tract, as well as to aid in removing microorganisms from the urinary tract. It is important to measure and record the client's intake and output every 8 hours and notify the primary health care provider if the urinary output decreases or the client fails to increase his or her oral intake. If the client is unable to maintain adequate intake, then he or she would be at risk for fluid imbalance. If renal injury would occur, then the client would be at risk for ineffective renal perfusion. Bladder training would be an appropriate intervention to address stress incontinence.
A client who is on sulfonamide therapy is about to be discharged. Which of the following precautions should the nurse instruct the client to follow to reduce the effects of photosensitivity?
- A. Wear protective clothing and sunscreen when outside.
- B. Increase fluid intake.
- C. Avoid lights while indoors.
- D. Wear protective footwear
Correct Answer: A
Rationale: The nurse should encourage a client to wear protective clothing while going out in the sun to reduce the effect of photosensitivity. While increasing the fluid intake is recommended, it does not help combat the effects of photosensitivity. There is no need to avoid lights while indoors; the skin becomes sensitive only to harsh sunlight during sulfonamide therapy. Wearing protective footwear may protect the feet from injury, but it will not protect the skin from the harmful effects of photosensitivity.
A client who is being discharged has been instructed to continue with sulfonamide therapy for a week. Which of the following points should the nurse include in the teaching plan to educate the client about the therapy?
- A. Discontinue dosage if symptoms of infection disappear.
- B. Take the drug a few minutes before a meal.
- C. Take any off-the-shelf medication if fever occurs.
- D. Ensure that all follow-up appointments are met
Correct Answer: D
Rationale: The nurse's plan should include educating the client about the importance of keeping the follow-up appointments. The nurse should instruct the client to adhere to the dosage schedule and not discontinue it even if the symptoms of the infection have gone. The client should inform the primary health care provider if fever, skin rash, or nausea occurs during the therapy. The client should be instructed to take the drug on an empty stomach (at least 2 hours before or after a meal) and not just before a meal.
