A patient with hypertension is prescribed a nonselective beta-blocker. The nurse reviewing this patient’s chart before administering the medication will be most concerned about which other disease process?

Renal artery ligation stenosis

Bronchial asthma

Diabetes mellitus

Coronary artery disease

Answer and Explanation

The Correct Answer is B

Choice A reason: Renal artery ligation stenosis is affected by beta-blockers’ renin reduction, but asthma’s bronchoconstriction risk is more immediate. Respiratory effects are critical, so this is incorrect.

Choice B reason: Nonselective beta-blockers can cause bronchospasm in asthma by blocking beta-2 receptors. This is a major concern, making it the correct disease to prioritize.

Choice C reason: Diabetes mellitus may mask hypoglycemia with beta-blockers, but asthma’s acute airway risk is more severe. Respiratory issues take precedence, so this is incorrect.

Choice D reason: Coronary artery disease benefits from beta-blockers’ cardiac effects. Asthma’s bronchoconstriction risk is more concerning, so this is incorrect for the primary concern.

Correct Answer is A

Explanation

Choice A reason: Drug-receptor binding either activates (agonists) or inhibits (antagonists) receptor activity, altering physiological responses. This is the primary effect, making it the correct choice for receptor interaction.

Choice B reason: Drugs do not permanently alter receptors non-responsive; they modulate activity temporarily. Non-responsiveness may occur with chronic use, but it’s not the primary effect, so this is incorrect.

Choice C reason: Preventing receptor action is specific to antagonists, not all drugs. drugs bind to receptors. Binding broadly affects activity, so this is incorrect for the general effect of receptor binding.

Choice D reason: Drugs do not give receptors new functions; they enhance or block existing ones. ones. Activity modulation is the key effect, making this incorrect for what occurs during binding.

A. Trade B. Proprietary C. Generic D. Chemical

Correct Answer is D

Explanation

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.
