A nurse is reviewing the home medications of a client who recently had transient ischemic attacks and is to begin taking clopidogrel. The nurse should instruct the client that which of the following over-the-counter medications interacts adversely with clopidogrel?

A. Recommend frequent hot baths: Hot baths can exacerbate symptoms in clients with multiple sclerosis by increasing fatigue and worsening muscle weakness due to a rise in core body temperature. Clients are usually advised to avoid overheating and use cooling strategies instead to manage their symptoms.

B. Encourage the client to restrict performing range-of-motion exercises: Range-of-motion exercises are important in maintaining joint flexibility, muscle strength, and overall mobility. Restricting these exercises could lead to increased stiffness, weakness, and decreased functional ability in clients with multiple sclerosis.

C. Monitor the client's ability to perform ADLs: Monitoring the client's ability to perform activities of daily living is essential because multiple sclerosis often leads to progressive physical limitations. Regular assessment helps in planning appropriate interventions, promoting independence, and adjusting care as the disease progresses.

D. Initiate contact precautions: Contact precautions are not necessary for clients with multiple sclerosis because it is not an infectious disease. Multiple sclerosis is an autoimmune, neurodegenerative condition that requires supportive care rather than infection control measures.

A. Hypertension: Hyponatremia typically leads to hypotension due to fluid shifts out of the vascular space rather than hypertension, especially if it is associated with hypovolemia. Low sodium levels can reduce blood volume and pressure, making hypertension an unlikely finding in this condition.

B. Muscle cramps: Muscle cramps are a common symptom of hyponatremia due to disrupted electrolyte balance affecting neuromuscular function. Low sodium levels impair muscle contraction and nerve signal transmission, leading to cramps, weakness, and fatigue.

C. Blurred vision: Blurred vision is not a typical manifestation of hyponatremia. While severe hyponatremia can cause neurological symptoms like confusion or seizures, visual disturbances like blurred vision are not primary signs linked to sodium imbalance.

D. Constipation: Constipation is more often associated with dehydration, immobility, or other electrolyte imbalances such as hypercalcemia. Hyponatremia primarily affects neuromuscular and central nervous system function rather than gastrointestinal motility.
