    • Every 2 hours

    • Every 1 hour

    • Ac&hs

    • At bedtime

    Correct Answer
    A. Every 1 hour
    Explanation
    During a MH (malignant hyperthermia) crisis, it is crucial to monitor glucose levels every 1 hour. This frequency allows for close monitoring of glucose levels, which can fluctuate rapidly during a crisis. By checking glucose levels every hour, healthcare professionals can ensure that the patient's blood sugar remains within a safe range and take appropriate actions if any abnormalities are detected.

    The treatment of MH should include which of interventions? - ProProfs

    The treatment of MH should include which of interventions?

    • Quickly resolving hyperkalemia

    • Administering Dantrolene

    • Cooling the patient's core temperature to 38 degrees C or 100.4 degrees F

    • Hyperventilating the patient

    • All of the above items are interventions for treating MH

    Correct Answer
    A. All of the above items are interventions for treating MH
    Explanation
    All of the interventions listed are necessary for the treatment of MH. Quickly resolving hyperkalemia is important to prevent cardiac complications. Administering Dantrolene helps to block the release of calcium in muscle cells, reducing muscle contractions and preventing further complications. Cooling the patient's core temperature to 38 degrees C or 100.4 degrees F helps to reduce metabolic activity and prevent further heat production. Hyperventilating the patient helps to lower carbon dioxide levels and prevent acidosis. Therefore, all of these interventions are essential in the treatment of MH.

    Select the amount of urine output you should expect with diureses during an MH crisis. - ProProfs

    Select the amount of urine output you should expect with diureses during an MH crisis.

    • Greater than 2ml/kg/hr

    • Greater than 1000ml every 12 hours

    • Greater than 1ml/kg/hr

    • Greater than 5ml/kg/hr

    Correct Answer
    A. Greater than 1ml/kg/hr
    Explanation
    During an MH crisis, the body experiences excessive muscle breakdown, leading to the release of myoglobin into the bloodstream. Myoglobin can cause kidney damage and result in decreased urine output. Therefore, the expected urine output during diuresis in an MH crisis should be greater than 1ml/kg/hr to ensure adequate renal function and prevent further complications.

    • Temperature decrease every 3 minutes

    • Increased creatine kinase

    • Coagulopathy

    • Cola colored urine

    • Metabolic alkalosis

    • Increased damage to the kidneys

    Correct Answer(s)
    A. Increased creatine kinase
    A. Coagulopathy
    A. Cola colored urine
    A. Increased damage to the kidneys
    Explanation
    Late signs of malignant hyperthermia (MH) include increased creatine kinase, coagulopathy, cola colored urine, and increased damage to the kidneys. These signs indicate that the condition has progressed and is causing systemic effects. Increased creatine kinase levels suggest muscle breakdown, which is a characteristic of MH. Coagulopathy refers to abnormal blood clotting, which can occur due to the release of certain substances during MH. Cola colored urine is a sign of myoglobinuria, which is the presence of muscle breakdown products in the urine. Increased damage to the kidneys indicates the severe impact of MH on organ function.
