The nurse is caring for a patient on a medical-surgical unit who has a fever of unknown origin. The prescriber has ordered a broad-spectrum antibiotic. Which intervention is the priority?
Obtaining all cultures before the antibiotic is administered
Delaying administration of the antibiotic until the culture results are available
Administering antipyretics as soon as possible
Administering the antibiotic immediately
The Correct Answer is D
A. Obtaining all cultures before the antibiotic is administered: While obtaining cultures is important for identifying the specific pathogen causing the infection and guiding targeted antibiotic therapy, waiting for culture results can take time. During this time, the infection can progress. Therefore, it's generally recommended to initiate broad-spectrum antibiotics first and then adjust the treatment based on culture results.
B. Delaying administration of the antibiotic until the culture results are available: Delaying antibiotics until culture results are available can be risky, as it allows the infection to progress, potentially leading to sepsis or other severe complications.
C. Administering antipyretics as soon as possible: Administering antipyretics like acetaminophen or ibuprofen can help reduce fever and make the patient more comfortable. However, the primary intervention for a suspected infection is antibiotic therapy, as it targets the underlying cause of the fever.
D. Administering the antibiotic immediately: When dealing with a patient with a fever of unknown origin and a suspected infection, the priority is to start appropriate antibiotic therapy promptly. Delaying antibiotic administration can allow the infection to worsen, leading to serious complications.

Correct Answer is A
Explanation
A. IgE (Immunoglobulin E): This class of antibodies is primarily involved in hypersensitivity reactions Type I, which are immediate allergic reactions. When a person is exposed to an allergen they are sensitive to, IgE antibodies on the surface of mast cells and basophils bind to the allergen. This triggers the release of inflammatory mediators like histamine, leading to allergic symptoms such as itching, hives, and in severe cases, anaphylaxis.
B. IgA (Immunoglobulin A): IgA antibodies are primarily found in mucosal areas such as the respiratory and gastrointestinal tracts. They play a role in immune defense on mucosal surfaces and are important for preventing infections. While IgA is not directly associated with hypersensitivity reactions Type I, deficiencies in IgA can sometimes lead to increased susceptibility to certain infections.
C. IgG (Immunoglobulin G): IgG antibodies are the most common type of antibody in the bloodstream and are involved in various immune responses, including defense against bacterial and viral infections. IgG antibodies are not specific to Type I hypersensitivity reactions; they are part of the immune system's broader defense mechanisms.
D. IgM (Immunoglobulin M): IgM antibodies are the first antibodies to be produced in response to an infection. They are large pentameric molecules and are effective at agglutinating pathogens. IgM antibodies are involved in the primary immune response to infections, but they are not specifically associated with Type I hypersensitivity reactions.
Correct Answer is A
Explanation
A. Ototoxicity and Nephrotoxicity:
Ototoxicity: Aminoglycosides can damage the inner ear structures, leading to hearing loss and balance issues.
Nephrotoxicity: These drugs can harm the kidneys, potentially causing acute kidney injury or chronic kidney disease. Monitoring kidney function is crucial to prevent renal damage.
B. Ototoxicity and Cardiotoxicity:
Ototoxicity: As mentioned above, aminoglycosides can damage the inner ear, affecting hearing and balance.
Cardiotoxicity: Aminoglycosides primarily affect the ears and kidneys; they do not directly target the heart. Cardiotoxicity is not a common side effect associated with aminoglycosides.
C. Hepatotoxicity and Nephrotoxicity:
Hepatotoxicity: This term refers to liver damage caused by drugs or toxins. Aminoglycosides are not known to cause liver problems; their primary concern is kidney damage.
Nephrotoxicity: As mentioned earlier, aminoglycosides can harm the kidneys, which is a well-known side effect.
D. Cardiotoxicity and Hepatotoxicity:
Cardiotoxicity: This term refers to the toxic effects on the heart, leading to various heart-related issues. Aminoglycosides do not primarily affect the heart; their main concerns are the ears (ototoxicity) and kidneys (nephrotoxicity).
Hepatotoxicity: Aminoglycosides are not typically associated with liver damage. They are primarily metabolized and excreted by the kidneys, which is why kidney monitoring is crucial during their use.
