A nurse is caring for a client who is prescribed diphenhydramine to relieve pruritus. The client asks the nurse how he can minimize the daytime sedation he is experiencing. Which of the following responses should the nurse give?

Benzonatate is available in capsule form (such as Tessalon Pearls), and it should be swallowed whole. It is important not to chew, crush, or break the capsules as this can cause adverse effects, including local anesthesia in the oral cavity, which can lead to choking or difficulty swallowing. Swallowing the capsule whole ensures that the medication is released properly in the stomach for the desired effect.

The other options mentioned are incorrect:
A. Eating a high-fat meal prior to taking medication: There is no specific requirement to eat a high-fat meal before taking Benzonatate. However, taking it with food or a glass of water may help with ease of swallowing.

B. Taking medication often and whenever a cough is starting: Benzonatate should be taken as directed by the healthcare provider. It is not recommended to take it more frequently or as needed, as it can lead to an overdose or unwanted side effects.

D. Taking medication with orange juice: There is no specific requirement to take Benzonatate with orange juice. It can be taken with water or other non-alcoholic beverages as directed by the healthcare provider.

Expectorants are medications that help to loosen and thin mucus in the respiratory tract, making it easier to cough up and expel. They work by increasing the production of respiratory tract secretions, which helps to hydrate and thin the mucus, making it less sticky and easier to clear from the airways. By stimulating the production and secretion of mucus, expectorants promote coughing and facilitate the removal of excess mucus and phlegm from the respiratory system.

It's important to note that expectorants are primarily used for productive coughs (coughs that produce phlegm or mucus). If the cough is dry and non-productive, other types of cough suppressants or remedies may be more appropriate.

Regarding the other options:

Reduces inflammation: Expectorants do not have a direct effect on reducing inflammation in the respiratory tract. Anti-inflammatory medications such as glucocorticoids are typically used for reducing inflammation in conditions like asthma or chronic obstructive pulmonary disease (COPD).

Dries mucous membranes: Expectorants do not have a drying effect on mucous membranes. In fact, they work to increase the hydration and fluidity of respiratory secretions.

Suppresses the urge to cough: Expectorants do not suppress the urge to cough. They promote coughing by facilitating the clearance of mucus and phlegm from the airways. Cough suppressants, on the other hand, are medications used to relieve a dry, non-productive cough by suppressing the cough reflex.
