A nurse is reviewing laboratory results for a client who has a fungal infection and is receiving itraconazole therapy.
Which of the following findings should alert the nurse to a potential adverse effect of this medication?

Elevated serum creatinine level

Decreased serum potassium level

Increased serum glucose level

Decreased white blood cell count.

Answer and Explanation

The Correct Answer is A

This is because itraconazole can cause renal impairment and decreased urine output as an adverse effect. A normal serum creatinine level is 0.6 to 1.2 mg/dL for males and 0.5 to 1.1 mg/dL for females.

Choice B is wrong because decreased serum potassium level is not an adverse effect of itraconazole. Itraconazole can cause hypokalemia, which is a low level of potassium in the blood, but this is usually due to fluid retention and heart failure caused by the drug. A normal serum potassium level is 3.5 to 5.0 mEq/L.

Choice C is wrong because increased serum glucose level is not an adverse effect of itraconazole. Itraconazole can cause hyperglycemia, which is a high level of glucose in the blood, but this is usually due to diabetes mellitus or steroid use in patients taking the drug. A normal serum glucose level is 70 to 100 mg/dL.

Choice D is wrong because decreased white blood cell count is not an adverse effect of itraconazole. Itraconazole can cause leukopenia, which is a low level of white blood cells in the blood, but this is usually due to bone marrow suppression or infection in patients taking the drug. A normal white blood cell count is 4,500 to 11,000 cells/mm3.

Correct Answer is A

Explanation

This is because nystatin suspension is an antifungal medication that works by coating the oral mucosa and killing the candida organisms.Swishing and swallowing the medication ensures that it reaches all the affected areas in the mouth and throat.

Choice B is wrong because administering the medication with a dropper to avoid aspiration is not necessary for a client who has oral candidiasis.

The client should be able to swish and swallow the medication without difficulty.

Choice C is wrong because diluting the medication with water before giving it to the client reduces its effectiveness and concentration.

The medication should be given undiluted for optimal results.

Choice D is wrong because giving the medication after meals to increase its effectiveness is not accurate.The medication should be given at least 30 minutes before or after meals to avoid interference with food or beverages.

A. Take the medication with an antacid to reduce gastric irritation. B. Drink plenty of fluids to prevent crystalluria. C. Avoid sexual intercourse until treatment is completed. D. Chew the tablets thoroughly before swallowing. E. Electrocardiogram.

Correct Answer is C

Explanation

The client should avoid sexual intercourse until treatment is completed.This is because trichomoniasis is a sexually transmitted infection that can be passed between partners during penile-vaginal sex or through transmission of infected vaginal fluids or fomites among women who have sex with women. Therefore, abstaining from sex until both partners are cured can prevent reinfection and transmission.

Choice A is wrong because taking the medication with an antacid can reduce its absorption and effectiveness.Tinidazole should be taken with food to minimize gastrointestinal side effects.

Choice B is wrong because drinking plenty of fluids to prevent crystalluria is not relevant for tinidazole.

Crystalluria is a condition where crystals form in the urine, which can cause kidney stones or damage.This is a potential complication of some antibiotics, such as sulfonamides, but not tinidazole.

Choice D is wrong because chewing the tablets thoroughly before swallowing is not necessary for tinidazole.Tinidazole tablets are film-coated and can be swallowed whole with water.

Chewing the tablets may alter their release and absorption, and may also cause a bitter aftertaste.
