A nurse is teaching a client about taking an expectorant to treat a cough. The nurse should explain that this type of medication has which of the following actions?
Reduces inflammation
Dries mucous membranes
Stimulates secretions
Suppresses the urge to cough
The Correct Answer is C
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.

Correct Answer is A
Explanation
Nasal glucocorticoids, also known as intranasal corticosteroids, are considered the most effective and recommended first-line treatment for nasal congestion caused by allergic rhinitis or non-allergic rhinitis. They work by reducing inflammation in the nasal passages, relieving congestion, and improving other symptoms such as itching, sneezing, and runny nose.
Leukotriene modifiers, decongestants, and antihistamines can also be used to manage nasal congestion, but they are generally considered second-line options or adjunct therapies.
Decongestants provide temporary relief by constricting blood vessels in the nasal passages, while antihistamines help with symptoms related to allergies. Leukotriene modifiers are primarily used for managing asthma and are not typically the first choice for nasal congestion alone.
Correct Answer is C
Explanation
Acetaminophen overdose can cause liver damage, and acetylcysteine is used as an antidote to prevent or minimize the liver injury caused by acetaminophen toxicity. Acetylcysteine works by replenishing glutathione, a substance that helps neutralize the toxic byproducts of acetaminophen metabolism in the liver.
It is important to note that acetylcysteine is specifically indicated for acetaminophen overdose and may not be effective or appropriate for overdosage of other drugs, such as ibuprofen, diphenhydramine, or amoxicillin.
