A nurse is assisting with the care of a postoperative client who has developed malignant hyperthermia.Which of the following actions should the nurse take?

Choice A rationale

Instilling a warm enema solution is not appropriate for treating malignant hyperthermia. The focus should be on cooling measures and medications.

Choice B rationale

Applying a cooling blanket is an appropriate action to help reduce the client's body temperature during malignant hyperthermia.

Choice C rationale

Administering meperidine IM is not indicated for malignant hyperthermia. The appropriate medications include dantrolene, cooling measures, and supportive care.

Choice D rationale

Ventilating the client with 100% oxygen, not 50%, is the appropriate action to ensure adequate oxygenation during malignant hyperthermia.

Choice A rationale

Obtaining blood pressure readings using the client's right arm can increase the risk of lymphedema in the affected arm.

Choice B rationale

Keeping both arms below the level of the client's heart can hinder proper lymphatic drainage and contribute to lymphedema.

Choice C rationale

Limiting range-of-motion exercises with the affected arm can cause stiffness and impede lymphatic flow, increasing the risk of lymphedema.

Choice D rationale

Using the client's left arm to obtain blood samples helps prevent unnecessary trauma to the right arm, reducing the risk of lymphedema.
