A nurse is teaching a client who has gastroesophageal reflux disease about how her diet can help reduce her discomfort. Which of the following foods should the nurse tell the client to avoid?

A) Administer dantrolene sodium IV: Dantrolene sodium is the treatment of choice for malignant hyperthermia. It acts as a muscle relaxant by inhibiting calcium release from the sarcoplasmic reticulum in skeletal muscles, which helps to halt the hypermetabolic crisis.

B) Monitor client for rapid decrease in heart rate: While monitoring vital signs is essential, a rapid decrease in heart rate is not a typical manifestation of malignant hyperthermia. The nurse should primarily focus on interventions to reduce hyperthermia and stabilize the client's condition.

C) Infuse chilled lactated Ringer's IV: Infusing chilled IV fluids can help lower the body temperature in malignant hyperthermia. However, this intervention is supportive and secondary to the administration of dantrolene sodium, which directly addresses the underlying pathophysiology.

D) Provide oxygen at 12 L/min via Venturi mask: Providing high-flow oxygen is necessary to manage hypoxia and metabolic acidosis associated with malignant hyperthermia. Nonetheless, this action is secondary to administering dantrolene sodium, which is crucial to stopping the hyperthermic crisis.

A) Fever: Myxedema coma is characterized by hypothermia rather than fever. The client with myxedema coma may experience a lowered body temperature, reflecting the severe hypothyroidism associated with this condition.

B) Hypernatremia: Hypernatremia, or elevated sodium levels, is a common finding in myxedema coma. This occurs due to impaired renal function and decreased aldosterone levels, leading to an imbalance in electrolytes, including sodium.

C) Hypertension: Typically, myxedema coma presents with hypotension rather than hypertension. The condition is associated with decreased cardiac output and low blood pressure, not elevated blood pressure.

D) Hypoglycemia: In myxedema coma, hypoglycemia is not typically expected. Instead, patients may experience hypoglycemia due to reduced metabolic rate and decreased glycogen stores. However, hyperglycemia is more commonly observed in other endocrine disorders, not specifically in myxedema coma.
