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. pH 7.30. PaCO2 38 P02 92, HCO3 15 B. pH 7.32. PaCO2 56, PO2 84, HCO3 26 C. pH 7.37. PaCO2:45, PO2 91, HCO3 24 D. pH 7.48. PaCO2 32, PO2 94. HCO3 22

Correct Answer is B

Explanation

A. pH 7.30, PaCO₂ 38, HCO₃ 15: Metabolic acidosis (low HCO₃, normal PaCO₂).

B. pH 7.32, PaCO₂ 56, PO₂ 84, HCO₃ 26: The client has respirations of 8/min, which indicates hypoventilation → CO₂ retention → respiratory acidosis. pH 7.32 indicates acidosis. PaCO₂ 56 mmHg - Elevated CO₂ (hypercapnia), confirming respiratory acidosis. HCO₃ 26- Normal bicarbonate suggests that compensation has not yet occurred

C. pH 7.37, PaCO₂ 45, HCO₃ 24: Normal ABG values.

D. pH 7.48, PaCO₂ 32, HCO₃ 22: Respiratory alkalosis (low PaCO₂ due to hyperventilation, not hypoventilation).
