Correct Answer is ["12.5"]
Explanation
Desired dose = 25 mg
Available concentration = 10 mg per 5 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = Available dose / Available volume
= 10 mg / 5 mL
= 2 mg/mL
Volume to administer = Desired dose / Available concentration
= 25 mg / 2 mg/mL
= 12.5 mL
Correct Answer is A
Explanation
A. "This will make it easier to cough up mucus.": Guaifenesin is an expectorant that works by thinning respiratory tract secretions, making it easier to mobilize and expel mucus through coughing. It does not suppress the cough reflex but facilitates a more productive cough.
B. "I should take this medication with other cough suppressants for best results.": Combining an expectorant like guaifenesin with a cough suppressant can be counterproductive. Suppressing the cough may prevent the effective clearing of loosened mucus, potentially worsening congestion.
C. "This medication will eliminate my cough within 24 hours.": Guaifenesin does not provide immediate relief and does not "eliminate" coughs. Its effectiveness depends on consistent use, and improvement may take a few days depending on the underlying cause of the cough.
D. "I should avoid drinking fluids while taking this medication.": Adequate fluid intake is essential while taking guaifenesin, as it enhances the medication's mucolytic effects. Dehydration can reduce its effectiveness and make secretions thicker and harder to clear.
