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 B
Explanation
A. Gut-associated lymphoid tissue (GALT): GALT is a component of the mucosa-associated lymphoid tissue (MALT) and refers to the immune cells found in the gastrointestinal tract. These cells play a significant role in local immune responses in the gut.
B. Bone marrow: The bone marrow is the primary site of blood cell production in the body. It contains stem cells that can differentiate into various blood cells, including B cells. B cells mature in the bone marrow.
C. Thymus: The thymus is an organ located near the heart and is crucial for the development of T cells. T cells mature in the thymus, where they learn to recognize self from non-self antigens.
D. Lymph nodes: Lymph nodes are small, bean-shaped structures that produce and store cells that help fight infection. While they are essential parts of the immune system, B and T cells are not originally derived from lymph nodes.
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.
