A nurse is teaching a class at a local senior center regarding safety in the home. A client states, "I am afraid of falling because I live alone and have no one to help me." Which of the following statements should the nurse make?

Rationale:
A. Encourage the client to eat a large meal in the evening: Clients with myasthenia gravis experience progressive muscle weakness, especially later in the day. Eating large evening meals increases the risk of fatigue and aspiration because muscle strength is reduced after activity.

B. Recommend the client eat within 45 min of taking cholinesterase-inhibitor medication: Cholinesterase inhibitors, such as pyridostigmine, enhance neuromuscular transmission and improve muscle strength. Eating within 45 minutes of taking the medication ensures optimal swallowing ability and reduces the risk of aspiration by aligning mealtime with peak effect.

C. Recommend the client extend their neck to facilitate swallowing: Extending the neck actually increases the risk of aspiration by opening the airway. Clients should be instructed to flex the neck slightly forward while swallowing to close the airway and promote safe swallowing mechanics.

D. Encourage the client to contact an occupational therapist to learn techniques of avoiding aspiration: While an occupational therapist can provide helpful adaptive techniques, primary aspiration prevention teaching should come directly from the nurse and speech-language pathologist.

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.
