A nurse is providing teaching to a client who has multiple sclerosis. Which of the following statements should the nurse include in the teaching?

Rationale:
A. Zolpidem: Zolpidem is a sedative-hypnotic used for insomnia and does not have known interactions with saw palmetto. It primarily affects the central nervous system and does not influence platelet activity or coagulation pathways.

B. Ipratropium: Ipratropium is an anticholinergic bronchodilator used for respiratory conditions such as COPD and asthma. It does not interact with saw palmetto, as the herb mainly affects hormonal and coagulation pathways rather than respiratory medications.

C. Clopidogrel: Saw palmetto can potentiate the effects of antiplatelet and anticoagulant medications like clopidogrel, increasing the risk of bleeding. The herb exhibits mild antiplatelet activity, which can lead to additive effects and potential hemorrhagic complications when combined with platelet inhibitors.

D. Penicillin: Penicillin is an antibiotic with no pharmacologic interaction with saw palmetto. The herb does not interfere with antibacterial mechanisms or alter antibiotic metabolism, making concurrent use safe from an interaction standpoint.

Rationale:
A. Walk with feet close together for stability: Walking with feet close together increases the risk of loss of balance and falls in clients with multiple sclerosis (MS). A wider stance provides greater stability and a safer base of support when ambulating.

B. Implement a rigorous range-of-motion exercise plan: While exercise is beneficial, a rigorous plan can lead to fatigue and exacerbate MS symptoms. Activities should be moderate and spaced with rest periods to prevent overexertion, which can worsen weakness and spasticity.

C. Use a cane for support while walking: Using a cane provides additional balance and stability, helping to prevent falls. Clients with MS often experience muscle weakness and impaired coordination, so assistive devices like canes or walkers promote safe mobility and independence.

D. Avoid the use of orthotics: Orthotic devices can be very helpful for clients with MS who experience foot drop or lower extremity weakness. Avoiding orthotics removes a potential source of support and increases the risk of tripping and falling during ambulation.
