While preparing to give an IM injection, the nurse aspirates and blood appears in the syringe.
The nurse should:

Choice A rationale

The charge nurse, by virtue of their leadership role and oversight of unit operations, is typically authorized to ensure patient safety and continuity of care. This includes re-verifying and administering medications in urgent situations when the preparing nurse is unavailable, adhering to established protocols and double-checking the medication before administration to prevent errors.

Choice B rationale

Limiting medication administration solely to the preparing nurse could delay critical treatment, especially during emergencies. While optimal, this practice is superseded by the need for timely patient care and adherence to a "second nurse check" policy, which enhances safety by having an additional qualified professional verify the medication.

Choice C rationale

Any licensed Registered Nurse (RN) or Licensed Practical Nurse (LPN) on the unit, if familiar with the patient and their condition, possesses the scope of practice and clinical competency to administer medications. This ensures patient safety through appropriate verification, patient identification, and adherence to the "rights" of medication administration, maintaining continuity of care.

Choice D rationale

Pharmacy technicians are not licensed healthcare professionals authorized to administer medications directly to patients. Their scope of practice is limited to preparing, packaging, and distributing medications under the supervision of a licensed pharmacist, lacking the clinical assessment and administration privileges of nursing staff.

Choice A rationale

The peak plasma level represents the maximum concentration of a drug achieved in the bloodstream after administration. While half-life influences the time to reach steady state, it does not directly determine the magnitude of the peak plasma level, which is more dependent on dose, absorption rate, and distribution volume.

Choice B rationale

Onset of action refers to the time it takes for a drug to exert its therapeutic effects after administration. While related to pharmacokinetic properties, the half-life primarily dictates the duration of drug presence and accumulation, not the immediate time to initial effect, which is more influenced by absorption and distribution.

Choice C rationale

A drug's half-life is the time it takes for the plasma concentration of a drug to be reduced by 50%. This pharmacokinetic parameter is critical for determining appropriate dosing intervals to maintain therapeutic drug levels within a desired range over a 24-hour period, preventing accumulation or sub-therapeutic concentrations.

Choice D rationale

The duration of effectiveness refers to the length of time a drug produces its therapeutic effect. While the half-life influences how long a drug remains in the system, the duration of effectiveness is also dependent on the drug's mechanism of action, receptor binding, and the patient's individual physiological responses, not solely on half-life.
