What does the acronym FEVER represent in relation to Neuroleptic Malignant Syndrome (NMS)?

The acronym FEVER in relation to Neuroleptic Malignant Syndrome (NMS) stands for Fever, Elevated enzymes, Vital instability, Encephalopathy, and Rigidity. This is significant because these symptoms collectively represent the critical features of NMS, a potentially life-threatening reaction to antipsychotic medications.

• Fever indicates a noticeable increase in body temperature, which is a common finding in patients experiencing NMS.

• Elevated enzymes refer to increased levels of creatine phosphokinase (CPK) and other enzymes in the bloodstream, indicating muscle breakdown and stress.

• Vital instability encompasses fluctuations in vital signs, such as blood pressure and heart rate, which can become erratic in affected individuals.

• Encephalopathy signifies a change in mental status, including confusion or altered consciousness, which reflects the impact of the syndrome on the central nervous system.

• Rigidity is a characteristic symptom that describes increased muscle tone, commonly observed in patients with NMS.

The other options contain terms that do not directly relate to the classic presentation of NMS and include symptoms that are either not part of the syndrome or do not capture the essence of the condition's clinical features. Thus, option B accurately encapsulates the essential symptoms of Neuroleptic Malignant
