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 C
Explanation
Pseudoephedrine is a sympathomimetic medication that acts as a decongestant by constricting blood vessels in the nasal passages, which helps to relieve sinus congestion. However, it can also cause vasoconstriction in other parts of the body, leading to an increase in blood pressure. Therefore, it is contraindicated for individuals with hypertension (high blood pressure).
The other conditions mentioned, migraines, eczema, and diverticulitis, are not contraindications for the use of pseudoephedrine. However, it is important for individuals with these conditions to consult their healthcare provider before taking pseudoephedrine, as it may interact with other medications or exacerbate certain symptoms.
Correct Answer is C
Explanation
Acetaminophen is a commonly used over-the-counter pain reliever and fever reducer. One of the potential adverse reactions to acetaminophen is liver toxicity, which can present with symptoms such as jaundice (yellowing of the skin and eyes), dark urine, and pale stools. It is important for the client to be aware of these signs and symptoms and report them to their healthcare provider if they occur. Monitoring for jaundice can help identify any potential liver-related complications associated with acetaminophen use.
The other options provided in the question are not typically associated with acetaminophen use:
- Tinnitus: Tinnitus refers to a perception of ringing or buzzing in the ears. It is not a commonly reported adverse reaction to acetaminophen.
- Hyperglycemia: Hyperglycemia refers to high blood sugar levels. Acetaminophen does not typically cause hyperglycemia as a side effect.
- Muscle pain: Acetaminophen is used to relieve mild to moderate pain, including muscle pain. It is not an adverse reaction to the medication.
