What is the maximum flow rate that can be set for a client who requires supplemental oxygen via a nasal cannula?

Rationale:
A. Addressing client questions about medications after administration is not ideal because clients may need information before taking their medications to ensure understanding, adherence, and informed consent.

B. Crushing all medications for a client with difficulty swallowing is unsafe. Some medications are extended-release, enteric-coated, or otherwise formulated to prevent irritation or ensure proper absorption. Crushing these can alter their effectiveness or cause harm. Medications should only be crushed if verified as safe by a pharmacist or prescriber.

C. Performing medication calculations to verify the correct dosages is the correct action. Older adults are at higher risk for adverse drug events due to age-related changes in metabolism, renal and hepatic function, and polypharmacy. Accurate calculation ensures the client receives the correct dose, preventing toxicity or subtherapeutic effects.

D. Scanning prescribed medications before entering the client’s room is a helpful safety step for barcode-assisted medication administration, but it is not specifically focused on the older adult population or on verifying dose accuracy. It complements but does not replace careful dose calculation and assessment.

Rationale:
A. While a client’s preference to take medications at a different time is important for adherence, it does not directly impact the ability to safely self-administer oral medications. Scheduling can often be adjusted under the nurse’s guidance.

B. Mild nausea after taking medication is an adverse effect to monitor, but it may not prevent the client from taking medications safely. It can often be managed with supportive measures or timing adjustments.

C. Needing help reading medication labels is a barrier that can be addressed with large-print labels, medication organizers, or caregiver assistance. While it affects independence, it does not inherently prevent safe medication ingestion.

D. Difficulty swallowing pills and tablets is the most critical finding when assessing the ability to self-administer oral medications. This can directly compromise safety by causing choking, aspiration, or incomplete dosing. Identifying this issue allows the nurse to implement alternative strategies, such as using liquid formulations, pill crushers, or other administration techniques, to ensure the client receives the full prescribed dose safely.
