A patient has been prescribed azithromycin, a macrolide antibiotic, for a respiratory infection.
The nurse should instruct the patient to report which of the following signs or symptoms of a potential adverse effect?

Diarrhea

Headache

Chest pain

Nausea.

Answer and Explanation

The Correct Answer is C

Azithromycin is a macrolide antibiotic that can cause a rare but serious side effect called QT prolongation, which affects the electrical activity of the heart and can lead to irregular heartbeats, chest pain, and sudden cardiac death. The patient should report any signs of chest pain or palpitations to the doctor immediately.

Choice A is wrong because diarrhea is a common side effect of azithromycin that usually does not require medical attention unless it is severe or bloody.

Choice B is wrong because headache is also a common side effect of azithromycin that usually does not require medical attention unless it is severe or persistent.

Choice D is wrong because nausea is another common side effect of azithromycin that usually does not require medical attention unless it is severe or accompanied by vomiting.

Correct Answer is A

Explanation

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.

A. Bactericidal B. Bacteriostatic C. Bacteriolytic D. Bacteriophage.

Correct Answer is B

Explanation

A bacteriostatic agent is an agent that inhibits the growth or reproduction of bacteria, but does not kill them.

This means that the bacteria are still alive, but they cannot multiply or cause infection.

Choice A) Bactericidal is wrong because a bactericidal agent is an agent with the capability to kill bacteria.

This means that the bacteria are no longer alive or viable.

Choice C) Bacteriolytic is wrong because a bacteriolytic agent is an agent that causes the lysis or rupture of bacterial cells.

This means that the bacteria are destroyed and their contents are released.

Choice D) Bacteriophage is wrong because a bacteriophage is not an agent, but a type of virus that infects and replicates within bacteria.

This means that the bacteriophage uses the bacteria as hosts and may kill them or not depending on the type of infection.
