A nurse is providing discharge teaching to a client who has a hearing impairment and a new hearing aid. Which of the following client statements indicates an understanding of the teaching?

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) Keep client in semi-Fowler's position with right extremity flat: Semi-Fowler's position is not optimal for a client with a compound fracture of the right tibia. Elevating the affected extremity, rather than keeping it flat, can help reduce swelling and pain.

B) Manage pain with oral opioids every 6 hr: While managing pain is crucial, oral opioids may not provide immediate relief needed in acute settings. Pain management should include a combination of strategies and may require IV analgesics for quicker relief.

C) Check capillary refill hourly for the first 24 hr: Although monitoring capillary refill is important to assess circulation, it is only one aspect of monitoring. Comprehensive assessment includes checking for signs of infection, neurovascular status, and compartment syndrome.

D) Apply a compression dressing over the fracture site: Applying a compression dressing can help control bleeding and reduce swelling. In a compound fracture, managing external bleeding and providing some stability to the fracture site are immediate priorities. However, the nurse should ensure this is done without compromising circulation and should be guided by physician orders.
