The OR nurse is taking the patient into the OR when the patient informs the operating nurse that his grandmother spiked a 104°F temperature in the OR and nearly died 15 years ago. What relevance does this information have regarding the patient?

Choice A reason: While the patient may indeed be anxious, the specific mention of a life-threatening intraoperative hyperthermic event in a blood relative is a clinical "red flag." The nurse must prioritize the physiological risk over the psychological state, as the family history suggests a specific, lethal genetic predisposition. Choice B reason: Malignant hyperthermia is an autosomal dominant pharmacogenetic disorder triggered by volatile inhalation anesthetics and succinylcholine. A family history of a high fever and near-death during surgery is a classic indicator of this condition. The surgical team must be notified immediately to prepare non-triggering anesthetic agents and dantrolene. Choice C reason: Family history is of paramount importance in surgical screening. Because malignant hyperthermia is a hereditary condition, a reaction in a first or second-degree relative significantly increases the patient's own risk. Dismissing this information as irrelevant would be a critical failure in preoperative safety and patient advocacy. Choice D reason: Postsurgical infections typically take days to manifest and do not present as an acute temperature spike of 104°F during the operation. The grandmother's sudden intraoperative temperature increase is highly specific to a metabolic crisis like malignant hyperthermia rather than a standard bacterial or viral infection process.
