A nurse is assessing a client with a temperature of 38.5°C (101.3°F) and a white blood cell count of 15,000/mm³. Which condition is the client most likely experiencing?
Bacterial infection.
Viral infection.
Fungal infection.
Parasitic infection.
The Correct Answer is A
Choice A rationale
Bacterial infection often leads to an elevated white blood cell count (15,000/mm³) and fever (38.5°C). The body’s immune response to bacterial pathogens results in these clinical manifestations.
Choice B rationale
Viral infections can cause fever, but they typically do not lead to a significant increase in white blood cell count.
Choice C rationale
Fungal infections can cause fever and elevated white blood cell count, but they are less common and usually occur in immunocompromised individuals.
Choice D rationale
Parasitic infections can cause fever and elevated white blood cell count, but they are less common and usually present with other specific symptoms.

Correct Answer is A
Explanation
Choice A rationale
Administering antipyretic medication as prescribed is a priority intervention for a client with a body temperature of 38°C (100.4°F). Antipyretics help reduce fever and provide comfort to the patient. They work by inhibiting the production of prostaglandins, which are involved in the fever response.
Choice B rationale
Encouraging fluid intake to prevent dehydration is also important, but it is not the priority intervention. Adequate hydration helps maintain fluid balance and supports the body’s ability to regulate temperature.
Choice C rationale
Monitoring vital signs every 4 hours is essential for assessing the patient’s condition, but it is not an intervention that directly addresses the fever. It helps track the patient’s response to treatment and detect any changes in their condition.
Choice D rationale
Applying a cooling blanket to reduce fever can be effective, but it is typically used when antipyretic medications are not sufficient or contraindicated. Cooling measures help lower body temperature through conduction and evaporation.
Correct Answer is A
Explanation
Choice A rationale
Elevated serum levels of troponin indicate cardiac cellular injury or death. Troponin is a protein released into the bloodstream when heart muscle cells are damaged, such as during a myocardial infarction.
Choice B rationale
Sustained glycogenolysis does not cause elevated troponin levels. Glycogenolysis is the breakdown of glycogen to glucose, primarily occurring in the liver and muscles, not related to troponin release.
Choice C rationale
Acute tubular necrosis does not elevate troponin levels. This condition affects the renal tubules and is typically indicated by elevated creatinine and BUN levels.
Choice D rationale
Troponin is not an acute phase reactant. Acute phase reactants are proteins whose levels change in response to inflammation, such as C-reactive protein (CRP), not troponin.
