A 7-year-old child with asthma uses a daily inhaled glucocorticoid and an albuterol MDI as needed. The provider has added montelukast (Singulair) to the child’s regimen. Which statement by the child’s parent indicates understanding of this medication?

I should notify my child’s pediatrician if I notice mood changes in my child.

I will give this medication to my child if I hear them wheezing.

This medication can cure my child’s asthma.

I should give this medication twice daily.

Answer and Explanation

The Correct Answer is A

Choice A reason: Montelukast can cause mood changes or neuropsychiatric effects in children. Recognizing this side effect and notifying the pediatrician shows understanding, making this the correct statement.

Choice B reason: Montelukast is a daily maintenance drug, not for acute wheezing, which requires albuterol. This misunderstanding of its use makes it incorrect for proper administration.

Choice C reason: Montelukast controls asthma symptoms but does not cure asthma, a chronic condition. This incorrect belief about its purpose makes it wrong for understanding the medication.

Choice D reason: Montelukast is dosed once daily, typically at bedtime, not twice daily. This dosing error indicates a lack of understanding, making it incorrect for the parent’s statement.

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. Antidotes B. Antagonists C. Agonists D. Activators

Correct Answer is B

Explanation

Choice A reason: Antidotes counteract specific toxins or drugs (e.g., naloxone for opioids). Antihistamines don’t neutralize allergens but block histamine receptors to reduce allergic symptoms like itching or sneezing. They target H1 or H2 receptors, not a toxin, making this choice incorrect for describing antihistamine mechanism of action.

Choice B reason: Antihistamines are antagonists, binding to histamine receptors (H1 or H2) without activating them, preventing histamine from triggering allergic responses like vasodilation or bronchoconstriction. This competitive inhibition reduces symptoms such as itching, sneezing, or gastric acid secretion, making this the correct choice for their pharmacological action.

Choice C reason: Agonists activate receptors to produce a response. Antihistamines block histamine receptors, not activate them, preventing allergic effects. Acting as agonists would mimic histamine, worsening symptoms like swelling or itching, which is opposite to their therapeutic role, making this choice incorrect.

Choice D reason: Activators is a vague term not used in pharmacology to describe drug action. Antihistamines specifically act as receptor antagonists, not general activators. They inhibit histamine effects without stimulating other pathways, making this choice inaccurate for explaining the mechanism of antihistamines in allergy management.
