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 D

Explanation

Choice A reason: Low drug interactions are desirable but unrelated to ease of administration. Adherence is directly tied to administration simplicity, so this is incorrect.

Choice B reason: Low production cost is a manufacturing benefit, not administration ease. Patient adherence is the outcome of easy administration, so this is incorrect.

Choice C reason: Storage stability aids logistics, not administration. Easy administration improves compliance, like taking oral pills, so this is incorrect for the outcome.

Choice D reason: Easy administration, like simple dosing or oral routes, enhances patient adherence by reducing barriers. This is the desired outcome, making it correct.

A. 5 mL B. 6 mL C. 4 mL D. 2 mL

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.
