D.

The Correct answer and Explanation is:
The correct answer is A. The dose of the medication that the client receives could cause drowsiness.
Explanation:
Robitussin A-C contains guaifenesin and codeine, an antitussive that works by suppressing the cough reflex. While effective for managing cough, particularly in cases of dry, nonproductive cough, one of the significant disadvantages of using antitussive therapy—especially one containing codeine—is the potential for sedation and drowsiness. This effect is particularly concerning for clients who need to maintain alertness for daily activities such as driving or operating machinery.
The drowsiness caused by codeine is due to its classification as an opioid. Opioids can depress the central nervous system, leading to sedation, which can be problematic for some patients. This side effect necessitates caution in prescribing and using codeine-based medications, especially in populations such as the elderly, those with respiratory conditions, or individuals on other CNS depressants.
Option B, stating that the medication is irritating to the bronchial tree, is incorrect because antitussives like codeine are generally not irritating; instead, they work to suppress irritation. Option C is misleading; while prolonged use of antitussives is not generally recommended, there isn’t a strict limit like 14 days for all patients—it can depend on the underlying condition. Option D is also incorrect, as Robitussin A-C is relatively affordable compared to other medications.
Overall, while Robitussin A-C can provide effective relief for coughs, healthcare providers must weigh the benefits against the risk of drowsiness and its impact on the patient’s daily functioning. Educating clients about this potential side effect is crucial to ensure their safety and adherence to therapy.
