The new post op client in PACU suddenly develops a temperature of 103 degrees F. What would you suspect?
The development of malignant hyperthermia
The development of fluid volume excess
The development of an allergic response to the pain medication
The development of an infection.
The Correct Answer is A
A. The development of malignant hyperthermia: Malignant hyperthermia (MH) is a life-threatening reaction to certain anesthetics (e.g., succinylcholine, halothane). It causes rapid muscle breakdown, severe hyperthermia, tachycardia, muscle rigidity, and metabolic acidosis. Immediate treatment with IV dantrolene and cooling measures is required.
B. The development of fluid volume excess: Fluid overload may cause hypertension and pulmonary edema but does not cause sudden high fever.
C. The development of an allergic response to the pain medication: Drug allergies typically present with rash, itching, or anaphylaxis, not extreme fever.
D. The development of an infection. Post-op infections usually develop over several days, not immediately in PACU.
