N-acetyl-para-aminophenol is an example of which type of drug name?

Trade

Proprietary

Generic

Chemical

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is D

Explanation

Choice A reason: To calculate volume, divide the ordered dose (40 mg) by the concentration (20 mg/mL): 40 ÷ 20 = 2 mL. Choice A (5 mL) delivers 100 mg (5 × 20), far exceeding the ordered dose, risking fluid and electrolyte imbalances, making it incorrect for safe administration.

Choice B reason: The correct volume is 40 mg ÷ 20 mg/mL = 2 mL. Choice B (6 mL) delivers 120 mg (6 × 20), significantly overdosing Lasix, which could cause severe dehydration, hypokalemia, or hypotension. This excessive dose is unsafe and incorrect for the prescribed administration.

Choice C reason: Calculating 40 mg ÷ 20 mg/mL yields 2 mL. Choice C (4 mL) delivers 80 mg (4 × 20), doubling the ordered dose. This could lead to excessive diuresis, electrolyte disturbances, or hypotension, making it an incorrect and potentially harmful choice for administration.

Choice D reason: Dividing the ordered dose (40 mg) by the concentration (20 mg/mL) gives 40 ÷ 20 = 2 mL. This volume accurately delivers the prescribed 40 mg of Lasix, ensuring effective diuresis for conditions like edema or heart failure while minimizing risks, making it the correct choice.

A. Respiratory alkalosis B. Respiratory acidosis C. Metabolic alkalosis D. Metabolic acidosis

Correct Answer is D

Explanation

Choice A reason: Respiratory alkalosis involves low PaCO2 (<35 mm Hg) due to hyperventilation, raising pH. Here, pH is 7.31 (acidic), PaCO2 is 41 mm Hg (normal), and HCO3- is 20 mEq/L (low), indicating a metabolic cause, not respiratory, making this choice incorrect.

Choice B reason: Respiratory acidosis requires elevated PaCO2 (>45 mm Hg), lowering pH. With PaCO2 at 41 mm Hg (normal) and low HCO3- (20 mEq/L), the acidosis stems from reduced bicarbonate, not CO2 retention, ruling out respiratory acidosis and making this choice incorrect.

Choice C reason: Metabolic alkalosis involves high HCO3- (>26 mEq/L) and elevated pH. Here, pH is 7.31 (acidic) and HCO3- is 20 mEq/L (low), indicating acidosis, not alkalosis. The low bicarbonate points to a metabolic cause, making this choice incorrect for the ABG values.

Choice D reason: pH 7.31 (acidic), PaCO2 41 mm Hg (normal), and HCO3- 20 mEq/L (low) indicate metabolic acidosis, likely from conditions like diabetic ketoacidosis or lactic acidosis. No respiratory compensation (normal PaCO2) confirms uncompensated metabolic acidosis, making this the correct choice for the imbalance.
