Malignant Hyperthermia Quiz: MCQ!

2.

The onset of Malignant Hyperthermia (MH) can be within minutes of the induction of the agent?

True
False

Correct Answer

A. True

Explanation

The onset of Malignant Hyperthermia (MH) can indeed occur within minutes of the induction of the triggering agent. MH is a potentially fatal reaction to certain medications used during general anesthesia, and it is characterized by a rapid increase in body temperature, muscle rigidity, and other symptoms. Prompt recognition and treatment are crucial to prevent complications and death. Therefore, it is important for healthcare providers to be aware of the potential rapid onset of MH after administering the triggering agent.

The MH cart is near the pyxis in PACU?

True
False

Correct Answer

A. True

Explanation

The statement suggests that the MH cart is located near the pyxis in the PACU. Since the answer is "True," it can be inferred that the MH cart is indeed near the pyxis in the PACU.

4.

Unexplained tachycardia, hyperthermia, and hypertension in a post-surgical patient should be treated as MH until proven otherwise?

True
False

Correct Answer

A. True

Explanation

In a post-surgical patient, the presence of unexplained tachycardia (rapid heart rate), hyperthermia (high body temperature), and hypertension (high blood pressure) suggests the possibility of malignant hyperthermia (MH). MH is a rare but potentially life-threatening condition that can occur as a reaction to certain medications used during anesthesia. It is important to treat it as MH until proven otherwise because prompt recognition and treatment are crucial to prevent complications and ensure patient safety. Therefore, the given answer of "True" is correct.

5.

Indicate how many teams are needed to mix Dantrolene?

4
Only the nursing supervisor is needed
2
3

Correct Answer

A. 2

Explanation

The question is asking how many teams are needed to mix Dantrolene. The correct answer is 2, indicating that only the nursing supervisor is needed. This suggests that the task of mixing Dantrolene can be accomplished by a single nursing supervisor without the need for additional teams or personnel.

6.

Select the item that is not a risk factor for MH.

Family History
Exhaustion
Heart Failure
Dehydration

Correct Answer

A. Heart Failure

Explanation

Heart failure is not a risk factor for malignant hyperthermia (MH). MH is a rare but potentially life-threatening condition triggered by certain medications used during general anesthesia. It is characterized by a severe reaction of the body's muscles to these medications. Risk factors for MH include a family history of the condition, exhaustion, and dehydration. However, heart failure is not directly associated with the development of MH.

Rate this question:

7.

Indicate the items that are early signs of MH.

Increase in end-tidal CO2
Muscle rigidity
Hypokalemia
Ventricular dysrhythmias
Bradycardia
Hypoxia

Correct Answer(s)

A. Increase in end-tidal CO2
A. Muscle rigidity
A. Ventricular dysrhythmias
A. Hypoxia

Explanation

The early signs of MH (malignant hyperthermia) include an increase in end-tidal CO2, muscle rigidity, ventricular dysrhythmias, and hypoxia. These signs indicate that the patient may be experiencing an adverse reaction to anesthesia, which can lead to a life-threatening condition. Hypokalemia and bradycardia are not typically associated with MH.

8.

Select the items that are late signs of MH.

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.

9.

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.

10.

What percentage of MH events reoccur?

50%
10%
60%
25%

Correct Answer

A. 25%

Explanation

The correct answer is 25%. This means that out of all MH events, 25% of them are likely to reoccur. This could indicate that there is a pattern or a recurring factor that contributes to these events happening again. It is important to study and understand these reoccurring events in order to prevent or mitigate their impact in the future.

The MH hotline number is 1-800-644-9737?

True
False

Correct Answer

A. True

Explanation

The given statement is true. The MH hotline number is indeed 1-800-644-9737.

Rate this question:

12.

When stable, the patient should be transferred to ICU for 24 hours.

True
False

Correct Answer

A. True

Explanation

When a patient is stable, it is standard practice to transfer them to the Intensive Care Unit (ICU) for 24 hours. This is done to ensure that the patient receives close monitoring and specialized care during this critical period. The ICU is equipped with advanced medical equipment and highly trained staff who can provide immediate attention and intervention if any complications arise. Therefore, transferring a stable patient to the ICU for 24 hours is a necessary precautionary measure to ensure their well-being and recovery.

Rate this question:

13.

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.

14.

Glucose should be checked at what frequency during a MH crisis?

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.
