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. IgG: Immunoglobulin G (IgG) is the most abundant antibody in the bloodstream and represents about 75% of all the antibodies in the body. It provides long-term immunity because it can persist in the bloodstream for a long time. IgG antibodies are involved in secondary immune responses and are capable of crossing the placenta, providing passive immunity to newborns.
B. IgE: Immunoglobulin E (IgE) is associated mainly with allergic reactions. When the body is exposed to an allergen, it triggers the release of IgE, leading to the symptoms of an allergic response, such as sneezing or itching.
C. IgM: Immunoglobulin M (IgM) is the largest antibody and is usually the first antibody produced during an initial exposure to an antigen. It is particularly effective at agglutination (clumping together) of pathogens.
D. IgA: Immunoglobulin A (IgA) is found in high concentrations in mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract. It provides localized defense against pathogens. IgA antibodies are also found in saliva, tears, and breast milk, providing immunity to infants.
Correct Answer is C
Explanation
A. Dermatitis and headaches: Prednisone use can sometimes cause skin issues, but dermatitis is not a common side effect. Headaches can also occur, but they are not specific to long-term prednisone therapy.
B. Heart failure and headaches: Prednisone does not directly cause heart failure. Headaches can occur but are not specific indicators of prednisone side effects.
C. Hyperglycemia and osteoporosis: Prednisone can lead to elevated blood glucose levels (hyperglycemia) and increased bone loss (osteoporosis) when used long-term. Regular monitoring is essential to manage these potential side effects.
D. Weight loss and hypoglycemia: Prednisone can cause weight gain rather than weight loss. Hypoglycemia (low blood sugar) is not a common side effect of prednisone; it typically causes hyperglycemia (high blood sugar) instead.
