When administering a drug to a patient in a boarding care home, what must be recorded on the personal care record?

Recording the quantity of the drug administered along with the initials of the caregiver is crucial in a boarding care home setting for several reasons. First, it provides a clear and verifiable record of exactly how much medication was given, which is essential for ensuring proper dosing and tracking medication use. This is particularly important in settings where multiple caregivers may be involved in administering medications, as it promotes accountability and traceability.

Including the initials of the individual who administered the medication helps maintain a responsible chain of custody; if any issues arise—such as an adverse reaction or an error in administration—it becomes easier to identify who was responsible. This information is vital for maintaining patient safety and ensuring proper care.

The other options, while important in their own contexts, do not encompass the complete necessity of dosage and accountability of the administration process in the way that recording the quantity of the drug and the caregiver's initials does. Hence, option C encapsulates critical information required for both patient safety and regulatory compliance in medication management within a boarding care environment.
