The nurse is preparing to give a drug that will prevent receptor activation. Which term would describe this drug?

Agonist

Antagonist

Potent

Selective

Answer and Explanation

The Correct Answer is B

Choice A reason: Agonists activate receptors, mimicking endogenous ligands, not preventing activation. The drug blocks receptors, so this is incorrect for the described action.

Choice B reason: Antagonists prevent receptor activation by blocking ligand binding, inhibiting effects. This matches the drug’s action, making it the correct term.

Choice C reason: Potent describes a drug’s strength, not its mechanism of preventing receptor activation. Antagonist defines the action, so this is incorrect.

Choice D reason: Selective refers to targeting specific receptors, not preventing activation. Antagonist describes the functional role, so this is incorrect.

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.

A. 1.4 mL B. 1.8 mL C. 1.2 mL D. 1.6 mL

Correct Answer is D

Explanation

Choice A reason: To calculate the volume, divide the ordered dose (8 mg) by the concentration (5 mg/mL): 8 ÷ 5 = 1.6 mL. Choice A (1.4 mL) underestimates the volume, delivering only 7 mg (1.4 × 5), which is insufficient for the prescribed dose, making it incorrect for accurate medication administration.

Choice B reason: Calculating 8 mg ÷ 5 mg/mL yields 1.6 mL. Choice B (1.8 mL) would deliver 9 mg (1.8 × 5), exceeding the ordered dose. This overdose could increase the risk of sedation or respiratory depression, as Valium (diazepam) is a benzodiazepine with potent CNS effects, making this choice incorrect.

Choice C reason: The correct volume is 8 mg ÷ 5 mg/mL = 1.6 mL. Choice C (1.2 mL) delivers only 6 mg (1.2 × 5), which is below the prescribed dose. This underdose could result in inadequate therapeutic effects, such as insufficient anxiety relief or seizure control, making it an incorrect choice.

Choice D reason: Dividing the ordered dose (8 mg) by the concentration (5 mg/mL) gives 8 ÷ 5 = 1.6 mL. This volume accurately delivers the prescribed 8 mg of Valium, ensuring therapeutic efficacy for conditions like anxiety or seizures while minimizing risks of over- or under-dosing, making it the correct choice.
