A patient is admitted with severe hypertensive crisis. The nurse will anticipate administering which medication?

Choice A reason: NPH insulin is not mixed with insulin glargine, as glargine’s pH and formulation cause precipitation or altered pharmacokinetics when combined. NPH can be mixed with regular insulin, as they are compatible, making this choice incorrect for the patient’s reported practice.

Choice B reason: NPH and regular insulin are compatible and routinely mixed in one syringe to provide both intermediate and short-acting coverage. They don’t react chemically or lose efficacy when combined properly, making this choice incorrect, as mixing is a standard practice in diabetes management.

Choice C reason: Mixing NPH and regular insulin does not increase potency; it combines their pharmacokinetics for basal and prandial glucose control. The mixture delivers the additive effects of each insulin’s profile without enhancing overall potency, making this choice inaccurate for their combined action.

Choice D reason: Mixing NPH (intermediate-acting) and regular insulin (short-acting) is an accepted practice to manage type 1 diabetes with one injection, covering basal and prandial needs. Proper technique (drawing regular insulin first) ensures stability, making this the correct choice for the patient’s reported insulin administration.

Choice A reason: Trade names are brand-specific (e.g., Tylenol for acetaminophen). N-acetyl-para-aminophenol is the chemical structure name, not a marketed brand. Trade names are proprietary and vary by manufacturer, while chemical names describe molecular composition, making this choice incorrect for the given term.

Choice B reason: Proprietary names are brand names owned by manufacturers (e.g., Advil for ibuprofen). N-acetyl-para-aminophenol is the chemical name for acetaminophen, not a proprietary or trade name, which is used for marketing purposes, making this choice incorrect for the drug’s nomenclature.

Choice C reason: Generic names are non-proprietary, like acetaminophen for N-acetyl-para-aminophenol. The term given is the chemical name, describing the molecular structure, not the standardized generic name used in clinical practice, making this choice incorrect for classifying N-acetyl-para-aminophenol.

Choice D reason: N-acetyl-para-aminophenol is the chemical name for acetaminophen, describing its molecular structure (an acetyl group on a para-aminophenol backbone). Chemical names are used in scientific contexts, distinct from generic or trade names, making this the correct choice for the drug’s nomenclature.
