Which term is used to describe an agent that inhibits bacterial growth but does not kill bacteria?
Bactericidal
Bacteriostatic
Bacteriolytic
Bacteriophage.
The Correct Answer is B
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.

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.
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.
