• Question 1
1 out of 1 points
Sulconazole has been prescribed for a patient with tinea pedis. The nurse will instruct the patient to use the topical agent
Response Feedback:
The nurse will advise the patient to use the medication once a day. Dosage strength indicates a single daily dose as the therapeutic treatment.
• Question 2
1 out of 1 points
A patient has endocarditis and is taking gentamicin. The nurse will be sure to monitor which of the following?
Response Feedback
:
Gentamicin is nephrotoxic and can result in acute tubular necrosis. The nurse will need to monitor for excessive urea level in the blood, decreased creatinine clearance, loss of the ability to concentrate urine, increased white blood cell count in the urine, and cells or casts in the urine. Potassium, albumin level, and prothrombin time are not associated with the adverse effects of gentamicin.
• Question 3
1 out of 1 points
Mr. Laird is a 49-year-old electrician who experienced severe burns on his trunk, arms, and hands in a workplace accident 2 weeks ago. Part of his current wound care regimen involves the daily application of silver sulfadiazine to his wounds. The nurses who are providing care for Mr. Laird in the burns and plastics unit of the hospital should perform what action when administering this medication?
Response Feedback
:
Before applying silver sulfadiazine, it is necessary to cleanse the wound completely and remove dead or burned skin and other debris. It would be inappropriate to perform wound care after the application of the drug and it should be applied in a thin layer no more than about 1/16 inch. Application of topical sulfonamides is a sterile, not clean, procedure.
• Question 4
A 30-year-old African-American woman tested positive for TB and is
1 out of 1 points
prescribed isoniazid. The nurse will plan the patient's care to include close monitoring of the drug therapy because
Response Feedback
:
Isoniazid is metabolized in the body through a process called acetylation, which is faster in Eskimos, Asians, and approximately 50% of African Americans or European Americans from North America than in Scandinavians and people of Arab or Jewish heritage. Because the patient is an African American, she may exhibit slow acetylation for the drug, and as a result she may be at greater risk for serum levels and adverse effects. For this reason, the nurse would need to closely monitor this particular patient. Patients of African-American descent do not exhibit slow therapeutic effects of isoniazid or high rates of drug elimination.
• Question 5
1 out of 1 points
A 46-year-old man is receiving a quinupristin/dalfopristin IV infusion for a life-threatening infection. Which of the following would be most important for the nurse to monitor?
Response Feedback
:
During quinupristin/dalfopristin infusion, the nurse should monitor the IV site for signs of infiltration, edema, or phlebitis. The nurse should also question the patient about pain at the injection site.
Quinupristin/dalfopristin is not known to affect heart rate or cause breathlessness. Nausea and vomiting have not been identified as common adverse effects of quinupristin/dalfopristin infusion.
• Question 6
A nurse is providing education to a patient who is taking INH. The nurse will advise the patient to avoid which of the following foods?
1 out of 1 points
Response Feedback
:
Patients who take INH should avoid eating tyramine, histamine- rich foods, and foods containing caffeine. Also, the patient should be told to avoid consuming alcohol on a daily basis. Cheese, dairy products, chicken liver, beer, ale, bananas, and figs are rich in tyramine. Tuna, brine, and yeast extracts are rich in histamine. Patients need not refrain from eating potatoes, root vegetables, chicken, fish, or citrus fruits.
• Question 7
1 out of 1 points
A 43-year-old man has been diagnosed with active TB. He is prescribed a multiple drug therapy, including INH and rifampin. A priority assessment by the nurse will be to monitor which combination of laboratory test results?
Response Feedback
:
The major adverse effect of INH therapy is hepatotoxicity. In hepatotoxicity the hepatic enzyme levels of aspartate transaminase and alanine transaminase will be elevated. Bilirubin will also be elevated, and the patient may present with jaundice. Red and white blood counts and differential would indicate possible hematologic effects, which could be considered adverse effects of the drug therapy, but would not be diagnostic for hepatotoxicity. Thyroid-stimulating hormone, thyroxine, and triiodothyronine levels would indicate a thyroid glandular concern, not hepatotoxicity. Fasting blood sugar and 2-hour postprandial blood sugar would be indicative of diabetes, not hepatotoxicity.
• Question 8
1 out of 1 points
An immunocompromised patient with a diagnosis of candidiasis has failed to respond to conservative therapy and has consequently begun treatment with amphotericin B. The nurse is aware that this drug achieves a therapeutic effect by way of its influence on
Response Feedback:
Amphotericin B works by binding to sterols in fungal cell membranes. This binding appears to form pores or channels and results in increased cell permeabili [Show Less]
