Physician: Physicians are responsible for diagnosing conditions, prescribing medications, and determining treatment plans, but they do not directly administer medications or assess immediate patient responses after administration.

Advanced Practice Registered Nurse (APRN): APRNs have prescriptive authority and provide advanced care, but in most settings, they do not carry out routine medication administration or perform frequent post-administration evaluations.

Pharmacist: Pharmacists dispense medications and provide education on drug use and interactions. They do not administer medications or assess the patient's response after administration.

The brand name given by the manufacturer refers to the trade or proprietary name, which is selected for marketing purposes and can vary between companies and countries.

The molecular structure of the drug refers to the chemical name, which describes the drug’s exact chemical composition and structure, not the generic name.

The trade name used in marketing is the brand name given by the pharmaceutical company to promote the drug commercially, distinct from its generic designation.

Morphine sulfate causes constipation because it slows gastrointestinal motility by acting on opioid receptors in the gut. This is a common side effect rather than an explanation of the drug’s therapeutic action.

Tetracycline stains developing teeth in children because it binds to calcium in developing bones and teeth, leading to discoloration. This is an adverse effect rather than how the drug works against bacteria.

Digoxin toxicity increases with hypokalemia because low potassium levels enhance digoxin’s binding to cardiac tissue, increasing its effects and the risk of dysrhythmias. This reflects a condition that worsens toxicity rather than explaining how the drug works.

Routine order refers to medications given on a scheduled, ongoing basis such as daily or twice daily. These do not require immediate action and are administered at predetermined times as part of the client’s regular care.

Standing order outlines treatments to be carried out under specific conditions (e.g., chest pain or fever), but the medication is only given if the specified situation arises, not automatically or immediately.

PRN order authorizes the medication to be administered as needed based on the patient’s condition, but it does not indicate that the medication should be given immediately unless symptoms are present.

Verifying the patient’s diagnosis helps ensure the medication is appropriate, but it does not directly confirm the patient's identity before administering the drug.

Calculating the correct dosage range ensures the Right Dose is administered but does not address confirming the patient’s identity, which is the focus of the Right Patient principle.

Administering medications on time fulfills the Right Time requirement but does not verify the patient’s identity, which is critical before any administration.
