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.

Answer and Explanation

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.

Correct Answer is A

Explanation

A. Chloride level would be decreased: Metabolic alkalosis is often associated with hypochloremia, especially when caused by vomiting or diuretics. However, hypokalemia is more clinically significant.

B. Sodium level would be elevated: Sodium levels are not directly affected by metabolic alkalosis.

C. Magnesium level would be elevated: Magnesium levels are not significantly altered in metabolic alkalosis.

D. Potassium level would be decreased: A bicarbonate level of 30 mEq/L indicates metabolic alkalosis. In alkalosis, hydrogen ions shift out of the cells, and potassium moves into the cells, leading to hypokalemia.

A. Diphenhydramine B. Famotidine C. Omeprazole D. Ondansetron

Correct Answer is D

Explanation

A. Diphenhydramine: An antihistamine used for motion sickness, but not first-line for severe nausea and dehydration.

B. Famotidine: A histamine-2 blocker used for acid reflux, not nausea control.

C. Omeprazole: A proton pump inhibitor for acid suppression, not for nausea and vomiting.

D. Ondansetron: Ondansetron (Zofran) is a serotonin (5-HT3) receptor antagonist that is highly effective for nausea and vomiting, especially in dehydration and severe vomiting.
