High body temperature
Correct Answer : A,C,D,F
Muscle rigidity is a hallmark sign of malignant hyperthermia. It commonly affects the muscles of the jaw and upper chest.
Malignant hyperthermia can lead to rapid and shallow breathing, resulting in tachypnea. Malignant hyperthermia is characterized by a significant increase in body temperature, often exceeding 38.8°C (101.8°F).
Malignant hyperthermia can cause irregular heart rhythms or dysrhythmias, including tachycardia or arrhythmias.
The manifestations of hypertension and skin mottling are not typically associated with malignant hyperthermia. Hypertension (high blood pressure) is more commonly seen in conditions such as hypertensive emergencies or certain cardiovascular disorders. Skin mottling, which refers to irregular or patchy skin coloration, is not a specific manifestation of malignant hyperthermia.

Explanation
Loop diuretics, such as furosemide, are known to cause potassium loss as they increase urine output. A potassium level of 1.5 mEq/L indicates severe hypokalemia (low potassium levels), which can be potentially dangerous and lead to various complications, including cardiac arrhythmias.
Hence, it is important to hold the dose of the loop diuretic and notify the physician so that appropriate interventions can be taken to address the low potassium level, such as prescribing potassium supplementation or adjusting the dosage of the loop diuretic.
A sodium level of 144 is within the normal range (135-145 mEq/L) and does not require immediate action.
A blood pressure of 102/78, although it may indicate hypotension, does not necessarily require holding the dose of the loop diuretic unless it is accompanied by other significant symptoms or clinical concerns.
A calcium level of 9 mg/dL falls within the normal range (8.5-10.5 mg/dL) and does not necessitate holding the loop diuretic dose.
