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.
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","B","C","E"]
Explanation
Cefazolin can cause serious or life-threatening allergic reactions in some patients, especially those with a history of penicillin allergy.The most common allergic reactions to cefazolin are immediate reactions, such as anaphylaxis, urticaria, bronchospasm, and angioedema.These reactions usually occur within one hour of the drug administration and may involve symptoms such as rash, itching, swelling, difficulty breathing, low blood pressure, and shock.Immediate reactions are mediated by immunoglobulin E (IgE) antibodies that bind to the drug and trigger the release of inflammatory mediators from mast cells and basophils.
Choice D is wrong because Stevens-Johnson syndrome is not a typical allergic reaction to cefazolin.
Stevens-Johnson syndrome is a rare and severe skin reaction that can be caused by various drugs, infections, or autoimmune diseases.
It involves blistering and peeling of the skin and mucous membranes, fever, malaise, and eye inflammation.
Stevens-Johnson syndrome is not mediated by IgE antibodies, but by other immune mechanisms that damage the skin cells.
Cefazolin is not known to cause Stevens-Johnson syndrome, although other cephalosporins have been reported to do so in rare cases.
Correct Answer is A
Explanation
Maraviroc is aCCR5 coreceptor antagonistthat blocks the receptor site the HIV virus needs to interact with in order to enter the cell.It prevents viral fusion with host cell membrane by binding to the CCR5 receptor on CD4+ T cells and macrophages.
Choice B is wrong becauseAbacavir is wrong because it is anucleoside reverse transcriptase inhibitor (NRTI)that inhibits the enzyme reverse transcriptase, which converts viral RNA into DNA.
It does not prevent viral fusion with host cell membrane.
Choice C is wrong becauseDarunavir is wrong because it is aprotease inhibitor (PI)that inhibits the enzyme protease, which cleaves viral proteins into functional units.
It does not prevent viral fusion with host cell membrane.
Choice D is wrong becauseFosamprenavir is wrong because it is also aprotease inhibitor (PI)that inhibits the enzyme protease.
It does not prevent viral fusion with host cell membrane.
