A nurse is caring for a client who has chronic glomerulonephritis and has developed metabolic acidosis. Which of the following medications should the nurse expect to administer?

A) Double-bag the client's trash before removing it from the room: Double-bagging trash is typically recommended for patients with highly contagious and severe infectious diseases, such as those requiring contact precautions. Influenza, while contagious, does not necessitate this level of precaution.

B) Place the client in a negative air pressure room with 6 to 12 air exchanges per hour: Negative air pressure rooms are used for airborne diseases like tuberculosis or measles, which can spread through the air over long distances. Influenza primarily spreads through respiratory droplets, so this precaution is not necessary.

C) Ensure all air in the client's room is filtered through a HEPA filter: HEPA filters are used for airborne pathogens to filter out infectious particles. Since influenza spreads via respiratory droplets rather than airborne particles, this level of air filtration is not required.

D) Wear a surgical mask when within 1 m (3 ft) of the client: Influenza spreads through respiratory droplets, which can travel up to about 1 meter (3 feet) when a person coughs or sneezes. Wearing a surgical mask within this distance helps prevent inhalation of these droplets, making it the appropriate precaution for influenza.

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.
