Question

pharmacology made easy 5.0 the respiratory system test question: 11 of 25 time remaining: 16:10:01 flag for which of the following reasons should a nurse instruct a client to avoid taking guaifenesin with combination over - the - counter cold products? over - the - counter cold products can also contain guaifenesin. blood glucose levels are increased. rebound congestion is likely. medication tolerance is likely.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Combination OTC cold products may already contain guaifenesin. Taking guaifenesin separately with them would lead to double - dosing, which can cause adverse effects.
• Option 2: Guaifenesin does not typically increase blood glucose levels, so this is not a reason to avoid combining it with OTC cold products.
• Option 3: Rebound congestion is associated with decongestant use (like nasal sprays), not guaifenesin, so this is incorrect.
• Option 4: Medication tolerance is not a primary concern when combining guaifenesin with OTC cold products; the main issue is potential double - dosing, not tolerance development.

So the correct reason is that OTC cold products can also contain guaifenesin.

Answer:

A. Over - the - counter cold products can also contain guaifenesin.
