A nurse is caring for a client who reports taking 0.5 oz of diphenhydramine elixir every night to sleep. The concentration on the client's bottle reads diphenhydramine 12.5 mg/5 mL. How many mg of diphenhydramine is the client taking each night? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. "I will hold my cellphone on the opposite side of the pacemaker.": Cellphones emit electromagnetic signals that can interfere with pacemaker function if held directly over the device. Keeping the phone on the opposite side minimizes the risk of interference and ensures proper pacemaker function.

B. "I can resume physical activity within 2 weeks.": Strenuous physical activity should be avoided for about 4-6 weeks to allow proper healing of the pacemaker site. Early resumption of activity can lead to lead dislodgement or complications.

C. "I need to cover my pacemaker with a dressing when I shower.": After the initial post-procedure period, there is no need to keep the pacemaker site covered while showering. The incision should be kept dry until it fully heals, but a permanent dressing is unnecessary.

D. "I should avoid using a microwave oven.": Modern pacemakers are shielded against microwave interference, making it safe to use a microwave. This is a common misconception, as older pacemakers were more susceptible to electrical interference.

A. Contact your pharmacy to inquire about a different medication: Pharmacies may offer generic alternatives, but they cannot change a prescription without provider authorization. A social worker can explore financial assistance programs, which is a more comprehensive solution.

B. I can arrange for a social worker to talk with you before you leave: Social workers assist clients in finding resources such as medication assistance programs, prescription discount plans, or community aid. This ensures the client can access their medication without financial strain.

C. You should ask your provider to prescribe a cheaper medication: While discussing cost-effective alternatives with the provider is an option, it does not directly address the client’s financial concerns. A social worker can provide broader support beyond just switching medications.

D. I can contact the occupational therapist to schedule a home visit: Occupational therapy focuses on improving daily function and independence. It does not address financial concerns related to medication affordability, making this option inappropriate for the situation.
