A nurse is providing discharge teaching to a female client who has the communicable disease herpes simplex virus II. Which of the following instructions should the nurse include in 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) "This medication might cause urinary frequency": Meclizine is not commonly associated with urinary frequency. It is an antihistamine used primarily to manage symptoms of vertigo and motion sickness rather than affecting urinary function.

B) "This medication might cause an increase in your blood sugar": Meclizine does not typically affect blood sugar levels. Concerns about blood sugar levels are more relevant to other medications, such as corticosteroids or certain antihypertensives, rather than meclizine.

C) "This medication might cause you to have excess saliva": Excess saliva is not a common side effect of meclizine. Antihistamines like meclizine usually have the opposite effect, potentially causing dry mouth rather than an increase in saliva.

D) "This medication might cause drowsiness": Drowsiness is a known side effect of meclizine, as it is an antihistamine with sedative properties. This effect can be significant for some individuals, so it's important for clients to be aware of this potential impact on their daily activities.
