A nurse is evaluating the laboratory report for a client who has severe diarrhea and a fever. Which of the following laboratory findings should the nurse identify as an indication that the client has a parasitic infection rather than a bacterial infection?
Decreased neutrophil count
Elevated eosinophil count
Increased hemoglobin level
Elevated platelet count
The Correct Answer is B
Choice A reason: A decreased neutrophil count is not typically associated with parasitic infections. Neutrophils are a type of white blood cell that responds to bacterial infections, so a decrease might be seen in viral infections or certain inflammatory conditions, but not specifically indicative of a parasitic infection.
Choice B reason: An elevated eosinophil count is often associated with parasitic infections, especially those involving tissue invasion. Eosinophils are white blood cells that play a crucial role in the immune response against parasitic infections. Normal eosinophil counts range from 0 to 500 cells per microliter of blood.
Choice C reason: An increased hemoglobin level is generally not related to the presence of a parasitic infection. Hemoglobin levels can be affected by various conditions, but they do not serve as a specific indicator for parasitic infections.
Choice D reason: An elevated platelet count can occur in various conditions, including inflammatory states and infections, but it is not a specific marker for parasitic infections. Platelets are components of blood that help with clotting and would not be used to differentiate between bacterial and parasitic infections.

Correct Answer is C
Explanation
Choice A reason: Diabetes mellitus is not directly associated with acute pancreatitis. However, longstanding diabetes can lead to chronic pancreatitis due to the damage it causes to the pancreas over time.
Choice B reason: Hyperlipidemia, specifically high levels of triglycerides in the blood, can be a risk factor for acute pancreatitis. Elevated triglyceride levels above 1000 mg/dL can precipitate an episode of acute pancreatitis.
Choice C reason: Gallstones are a common cause of acute pancreatitis. They can block the bile duct, leading to pancreatitis. It's estimated that gallstone disease is responsible for 3040% of acute pancreatitis cases.
Choice D reason: A criminal record is not a medical condition and has no relevance to the development of acute pancreatitis.
Correct Answer is B
Explanation
Choice A reason: Applying a tourniquet just below the elbow is not recommended as the first line of action for a deep laceration unless there is life-threatening hemorrhaging that cannot be controlled by direct pressure. Tourniquets are used as a last resort because they can cause tissue damage.
Choice B reason: Elevating the limb and applying ice can help reduce bleeding and swelling. Elevation uses gravity to help reduce blood flow to the injury, and the cold from the ice constricts blood vessels, further helping to control bleeding and reduce swelling.
Choice C reason: Cleaning the wound is important, but it should not be the first action taken. The initial focus should be on stopping the bleeding. Once bleeding is controlled, the wound can be cleaned to prevent infection.
Choice D reason: Applying pressure directly to the wound with a clean cloth or bandage is the first step in controlling bleeding. However, the question specifies applying pressure above the wound, which would not be effective in controlling bleeding from the wound itself.
