A nurse is providing discharge instructions to a patient prescribed Guaifenesin. Which of the following statements by the patient indicates correct understanding of the medication's use?
"This will make it easier to cough up mucus."
"I should take this medication with other cough suppressants for best results."
"This medication will eliminate my cough within 24 hours."
"I should avoid drinking fluids while taking this medication."
The Correct Answer is A
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.

Correct Answer is A
Explanation
A. "If my pain persists, I can safely increase the dose to 1500 mg every 4–6 hours.": This dose exceeds the maximum safe limit for acetaminophen. The recommended adult dose is no more than 1000 mg per dose and 4000 mg per day. Exceeding this can lead to serious hepatotoxicity, especially with prolonged use or preexisting liver conditions.
B. "I should use caution when taking acetaminophen with warfarin as it may affect my INR levels.": Acetaminophen can increase the anticoagulant effect of warfarin, possibly elevating INR and increasing the risk of bleeding. Regular monitoring is recommended when both drugs are used concurrently.
C. "I need to be cautious when taking other medications that may contain acetaminophen.": Many over-the-counter medications, such as cold and flu remedies, also contain acetaminophen. Accidental overdose can occur if this is not considered when calculating total daily intake.
D. "I should contact my healthcare provider if I experience yellowing of the skin or eyes.": Jaundice may be a sign of liver damage or failure due to acetaminophen toxicity. Early recognition of this symptom is critical for preventing serious complications.
Correct Answer is ["0.5"]
Explanation
Desired dose = 250 mg
The medication label for Chlorzoxazone Tablets, USP states: 500 mg per tablet.
- Determine the number of tablets needed:
Number of tablets = Desired dose / Dose per tablet
= 250 mg / 500 mg/tablet
= 0.5 tablet
