What are considered the ‘Big Three’ properties of an ideal drug? (Select all that apply)

Selectivity

Safety

Effectiveness

Irreversible action

A recognizable trade name

Answer and Explanation

Correct Answer : A,B,C

Choice A reason: Selectivity ensures a drug targets specific receptors, minimizing side effects. This is a key property of an ideal drug, making it a correct choice.

Choice B reason: Safety is critical, ensuring the drug causes minimal harm at therapeutic doses. This is a fundamental ideal drug property, so it is correct.

Choice C reason: Effectiveness ensures the drug achieves its intended therapeutic effect. This is essential for an ideal drug, making it a correct choice.

Choice D reason: Irreversible action is not ideal; reversible effects allow control and safety. The ‘Big Three’ focus on efficacy, safety, and selectivity, so this is incorrect.

Choice E reason: A trade name aids marketing but is not a pharmacological property. Effectiveness, safety, and selectivity are primary, so this is incorrect.

Correct Answer is B

Explanation

Choice A reason: Metabolic acidosis involves low pH and HCO3-; here, pH is normal, and HCO3- is high. Elevated PaCO2 compensates for high HCO3-, so this is incorrect for the ABG values.

Choice B reason: Normal pH (7.39), high HCO3- (29), and high PaCO2 (47) indicate metabolic alkalosis fully compensated by respiratory retention of CO2. This matches the values, making it correct.

Choice C reason: Respiratory alkalosis has low PaCO2 and normal or low HCO3-. Here, PaCO2 and HCO3- are high, ruling this out, so it’s incorrect for the given ABG profile.

Choice D reason: Respiratory acidosis has high PaCO2 and low pH. Normal pH and high HCO3- suggest metabolic alkalosis, not respiratory acidosis, making this incorrect for the values.

A. If nighttime awakenings occur more than 2 days per week B. Twice daily combined with an inhaled glucocorticoid C. Only with a long-acting beta2 agonist (LABA) D. As a rescue inhaler as needed for asthma symptoms

Correct Answer is D

Explanation

Choice A reason: Nighttime awakenings more than twice weekly indicate step 2, requiring maintenance therapy. Step 1 uses albuterol as needed, so this is incorrect.

Choice B reason: Twice-daily glucocorticoids are for step 2 or higher, not step 1, where albuterol is used as needed. This is incorrect for step 1 management.

Choice C reason: LABAs are used in step 3 or higher, not step 1, where albuterol alone is sufficient as needed. This is incorrect for the asthma step.

Choice D reason: At step 1, albuterol is used as a rescue inhaler for acute asthma symptoms. This is the standard approach, making it the correct choice.
