A nurse is caring for a client who has a wound infection caused by Staphylococcus aureus. The nurse notes that the wound has a creamy white or yellow, purulent, and sometimes bloody drainage. The nurse recognizes that this type of drainage is indicative of what type of exudate?

Choice C reason: Purulent exudate is a type of exudate that contains pus, which is composed of dead neutrophils, bacteria, and cellular debris. It has a creamy white or yellow, purulent, and sometimes bloody appearance and a foul odor. It is seen in wound infections caused by pyogenic bacteria, such as S. aureus.

Choice A reason: Serous exudate is a type of exudate that contains clear or yellowish fluid that accumulates in body cavities or on the surface of tissues. It has a watery and thin appearance and no odor. It is seen in conditions such as blisters or pericarditis.

Choice B reason: Sanguineous exudate is a type of exudate that contains blood or blood cells that leak from damaged blood vessels. It has a red or brown appearance and no odor. It is seen in conditions such as trauma, surgery, or malignancy.

Choice D reason: Fibrinous exudate is a type of exudate that contains fibrin, which is a protein that forms a meshwork of fibers that seal and stabilize the wound. It has a sticky and thick appearance and no odor. It is seen in conditions such as rheumatic fever or pleurisy.

Choice A reason: Eradicate the causative microorganism within 24 hours. The goal of antibiotic therapy in septic shock is to eradicate the causative microorganism as soon as possible, preferably within 24 hours of diagnosis or sooner if possible. This can reduce the bacterial load, control the infection, and prevent further complications.

Choice B reason: Reduce the inflammatory response within 48 hours is not the goal of antibiotic therapy in septic shock, as antibiotics do not directly affect the inflammatory response. Antibiotics can indirectly reduce the inflammatory response by eradicating the microorganism that triggers it, but this may take longer than 48 hours to achieve.

Choice C reason: Restore the tissue perfusion and oxygen delivery within 72 hours is not the goal of antibiotic therapy in septic shock, as antibiotics do not directly affect the tissue perfusion and oxygen delivery. Antibiotics can indirectly restore the tissue perfusion and oxygen delivery by eradicating the microorganism that causes vasodilation, hypotension, hypovolemia, and microvascular thrombosis, but this may take longer than 72 hours to achieve.

Choice D reason: Prevent the development of multiple organ dysfunction syndrome within 96 hours is not the goal of antibiotic therapy in septic shock, as antibiotics do not directly prevent the development of multiple organ dysfunction syndrome. Antibiotics can indirectly prevent the development of multiple organ dysfunction syndrome by eradicating the microorganism that causes tissue hypoxia, lactic acidosis, and organ failure, but this may take longer than 96 hours to achieve.
