The patient's temperature has reached 103.4° F. The nurse prepares to draw a blood culture before giving the patient an antipyretic medication. What is the best reason to draw a blood culture before giving an antipyretic medication?
a. The causative organism is most prevalent during a spike in temperature.
b. Elevated temperatures slow metabolic rate and improve blood oxygenation.
c. Increased blood flow leads to moist mucous membranes making blood draws easier.
d. Venous distention is greater because of fluid retention secondary to hyperthermia.
A
Obtain blood specimens at the same time as a temperature spike, when the causative organism is most prevalent. Satisfy requirements for increased metabolic rate. Provide supplemental oxygen therapy as ordered to improve oxygen delivery to body cells. Encourage oral hygiene because oral mucous membranes dry easily from dehydration and have increased potential for bacterial invasion. Replace fluids lost through insensible water loss and sweating.
