Under nurse delegation, who is allowed to administer medication?

In the context of nurse delegation, option B is correct because it defines the specific categories of personnel who are legally permitted to administer medication under the delegation framework established in Washington State. Healthcare assistants (HCAs), nurses' aides (NACs), and nursing assistants registered (NARs) have undergone specific training and certification that enables them to safely administer medications to patients when the delegation is provided by a registered nurse (RN).

The nursing practice laws set forth the requirements for delegation, which include ensuring that the person receiving the delegation is competent and that the medication administration falls within the scope of their training. The RN must assess the patient's needs and determine if delegation is appropriate, ensuring that the delegated tasks can be performed safely.

In contrast, other options do not align with the legal scope of practice under nurse delegation. Registered nurses have the authority to delegate but are not the only individuals permitted to administer medications in this context. The option that mentions only doctors and pharmacists is not applicable since the delegation process allows for trained HCAs and similar staff to administer medications when properly delegated by an RN. The definition of "trained medical staff" is too vague to determine who specifically can administer medications in the context of nurse delegation.
