A nurse is assisting with the induction of general anesthesia for a client who is undergoing a cholecystectomy. The nurse monitors the client for signs of malignant hyperthermia, which include:
Hypothermia, bradycardia, and hypotension are not signs of malignant hyperthermia, but rather signs of hypovolemia, shock, or anesthesia overdose. Malignant hyperthermia is a rare but life-threatening condition that occurs when a patient is exposed to certain anesthetic agents and develops a hypermetabolic response that leads to high fever, muscle rigidity, tachycardia, hypertension, acidosis, and rhabdomyolysis.
Hyperthermia, tachycardia, and hypertension are the classic signs of malignant hyperthermia. The patient may also experience increased carbon dioxide production, decreased oxygen saturation, dysrhythmias, cyanosis, muscle breakdown, and organ failure. The nurse should monitor the patient's vital signs, temperature, blood gases, electrolytes, and urine output closely and notify the anesthesia care provider immediately if malignant hyperthermia is suspected. The treatment involves stopping the anesthetic agent, administering 100% oxygen, cooling the patient with ice packs and cold intravenous fluids, and giving dantrolene sodium intravenously to relax the muscles.
Hypothermia, tachypnea, and hypertension are not consistent with malignant hyperthermia. Hypothermia may occur due to exposure to cold operating room environment or intravenous fluids. Tachypnea may be caused by pain, anxiety, hypoxia, or acidosis. Hypertension may be related to stress, pain, or sympathetic stimulation. These signs are not specific to malignant hyperthermia and do not indicate a hypermetabolic state.
Hyperthermia, bradypnea, and hypotension are not typical of malignant hyperthermia. Hyperthermia may occur due to infection, inflammation, or dehydration. Bradypnea may be a result of oversedation, opioid administration, or respiratory depression. Hypotension may be due to blood loss, dehydration, or vasodilation. These signs do not reflect a hypermetabolic state or muscle rigidity that are characteristic of malignant hyperthermia.
Choice A reason:
Hypothermia, bradycardia, and hypotension are not signs of malignant hyperthermia, but rather signs of hypovolemia, shock, or anesthesia overdose. Malignant hyperthermia is a rare but life-threatening condition that occurs when a patient is exposed to certain anesthetic agents and develops a hypermetabolic response that leads to high fever, muscle rigidity, tachycardia, hypertension, acidosis, and rhabdomyolysis.
Choice B reason:
Hyperthermia, tachycardia, and hypertension are the classic signs of malignant hyperthermia. The patient may also experience increased carbon dioxide production, decreased oxygen saturation, dysrhythmias, cyanosis, muscle breakdown, and organ failure. The nurse should monitor the patient's vital signs, temperature, blood gases, electrolytes, and urine output closely and notify the anesthesia care provider immediately if malignant hyperthermia is suspected. The treatment involves stopping the anesthetic agent, administering 100% oxygen, cooling the patient with ice packs and cold intravenous fluids, and giving dantrolene sodium intravenously to relax the muscles.
Choice C reason:
Hypothermia, tachypnea, and hypertension are not consistent with malignant hyperthermia. Hypothermia may occur due to exposure to cold operating room environment or intravenous fluids. Tachypnea may be caused by pain, anxiety, hypoxia, or acidosis. Hypertension may be related to stress, pain, or sympathetic stimulation. These signs are not specific to malignant hyperthermia and do not indicate a hypermetabolic state.
Choice D reason:
Hyperthermia, bradypnea, and hypotension are not typical of malignant hyperthermia. Hyperthermia may occur due to infection, inflammation, or dehydration. Bradypnea may be a result of oversedation, opioid administration, or respiratory depression. Hypotension may be due to blood loss, dehydration, or vasodilation. These signs do not reflect a hypermetabolic state or muscle rigidity that are characteristic of malignant hyperthermia.
