Which medication is indicated for suppression of cough? (Select all that apply)

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.

Choice A reason: Adrenergic neuron blockers, like guanethidine, reduce blood pressure by inhibiting norepinephrine release. They are not first-line for stage 1 hypertension (140-159/90-99 mm Hg). Their side effects, like orthostatic hypotension, make them less suitable. Lifestyle changes are preferred initially for this patient’s mild elevation and normal diagnostic tests, making this choice inappropriate.

Choice B reason: Beta blockers, like atenolol, reduce heart rate and cardiac output, lowering blood pressure. They are not first-line for stage 1 hypertension without compelling indications (e.g., heart failure). Guidelines recommend lifestyle modifications first for this patient’s blood pressure range, as they effectively reduce risk without medication side effects, making this choice less suitable.

Choice C reason: For stage 1 hypertension (140-159/90-99 mm Hg) with normal diagnostic tests, guidelines recommend lifestyle changes, such as diet, exercise, and weight loss, as first-line treatment. These reduce blood pressure by improving vascular health and reducing cardiac strain, offering a low-risk approach to manage mild hypertension effectively, making this the correct choice.

Choice D reason: ACE inhibitors, like lisinopril, block angiotensin II formation, reducing blood pressure. They are effective but not first-line for stage 1 hypertension without comorbidities. Lifestyle changes are prioritized to avoid medication side effects like cough or hyperkalemia, making this choice less appropriate for initial management in this patient.
