When should the medication label be compared to the medication administration record (MAR) as part of the medication administration process? Select all that apply.

Rationale:
A. Humidification is the correct intervention to reduce irritation to the mucous membranes in clients receiving supplemental oxygen. When oxygen is delivered at higher flow rates or for extended periods, it is typically dry, which can cause dryness and irritation of the nasal passages, throat, and airway. This can lead to discomfort, nosebleeds, increased mucus thickness, and even damage to the delicate mucosal lining. Adding a humidifier to the oxygen delivery system introduces moisture into the oxygen stream, helping maintain mucosal hydration, improve comfort, and reduce the risk of complications. Humidification can be especially important for clients on high-flow oxygen, long-term oxygen therapy, or those with preexisting respiratory conditions.

B. A filtering device, such as a bacterial or particulate filter, is designed to remove impurities, contaminants, or microorganisms from the oxygen supply. While filters improve the safety and cleanliness of the oxygen, they do not address dryness or prevent irritation of the mucous membranes.

C. Cooling agents are not used in oxygen therapy. Cooling the oxygen or air does not prevent dryness and may even exacerbate mucosal discomfort. This is not a recommended method for protecting mucous membranes.

D. Medication is not routinely added to oxygen systems to prevent mucosal irritation. Medications delivered via oxygen would only be used for specific therapeutic purposes, such as bronchodilation or nebulized therapy, and are not a general intervention for dryness or irritation.

Rationale:

A. Providing education to the client before administration helps prevent medication errors. Educated clients can participate in their care, question unfamiliar medications, and alert the nurse if something seems incorrect. Client engagement adds an additional safety check.

B. Avoiding phone calls during medication preparation is correct. Interruptions are a major cause of medication errors. Limiting distractions during preparation improves focus and reduces the risk of incorrect dosing or selection.

C. Turning off the television or radio to reduce noise is appropriate. A quiet environment decreases distractions and improves concentration during medication preparation and administration, promoting safe practice.

D. Preparing medications for multiple clients at the same time is unsafe and increases the risk of mixing up medications. Medications should be prepared for one client at a time to reduce the risk of error.

E. Asking the client if they have any allergies is essential. Verifying allergies before administration prevents adverse drug reactions and is a critical safety step.

F. Verifying medication calculations are correct helps prevent dosage errors. Double-checking calculations ensures the correct amount of medication is administered, especially for high-alert medications.
