When caring for a client with an upper respiratory infection (URI), the nurse is notified the client is taking guaifenesin (Mucinex). What is the mechanism of action of guaifenesin (Mucinex)?

Stimulate alpha-adrenergic receptors, thus producing vascular constriction of capillaries in nasal mucosa

Compete with histamine for receptor sites, thus preventing a histamine response and overall congestion.

Treat allergic rhinitis and prevent motion sickness.

Loosen bronchial secretion to assist in elimination.

Answer and Explanation

The Correct Answer is D

A. Stimulate alpha-adrenergic receptors, thus producing vascular constriction of capillaries in nasal mucosa: This describes the action of decongestants, not guaifenesin. Guaifenesin does not work by constricting blood vessels; rather, its primary function is to help manage mucus production.

B. Compete with histamine for receptor sites, thus preventing a histamine response and overall congestion: This mechanism is associated with antihistamines, which are used to relieve symptoms of allergic reactions, not with guaifenesin. Guaifenesin does not block histamine but focuses on mucus management.

C. Treat allergic rhinitis and prevent motion sickness: While these are common uses for antihistamines, they do not apply to guaifenesin. Guaifenesin is primarily an expectorant and is not indicated for treating allergic rhinitis or motion sickness.

D. Loosen bronchial secretion to assist in elimination: Guaifenesin acts as an expectorant, promoting the clearance of mucus from the airways by loosening bronchial secretions. This facilitates easier expectoration of mucus, helping to relieve chest congestion associated with upper respiratory infections.

Correct Answer is A

Explanation

A. This medication is for long-term treatment for asthma: This statement indicates an accurate understanding of montelukast. It is a leukotriene receptor antagonist used for long-term control and management of asthma symptoms and to prevent exercise-induced bronchoconstriction.

B. This medication has a tendency to produce anaphylaxis: This statement is incorrect. While allergic reactions can occur with montelukast, it is not commonly associated with anaphylaxis. Clients should be aware of potential side effects, but anaphylaxis is not a common risk.

C. I can repeat this medication twice prior to seeking medical attention: This statement is misleading. Montelukast is taken once daily for asthma management, and it is not meant to be repeated or used as a rescue medication in acute situations. Clients should seek medical attention for worsening symptoms instead of relying on repeating doses.

D. Bloodwork is required regularly to monitor the therapeutic levels of this medication: This statement is incorrect. Montelukast does not require routine blood monitoring for therapeutic levels, unlike some other medications used for asthma management. It is generally well-tolerated without the need for regular blood tests.

A. montelukast (Singulair) B. methylprednisolone (Solumedrol) C. ipratropium bromide (Atrovent) D. albuterol (Ventolin)

Correct Answer is C

Explanation

A) Montelukast (Singulair): This medication is a leukotriene receptor antagonist used to manage asthma and allergic rhinitis. It does not contain soy or soy-derived ingredients, making it a safe option for a client with a soybean allergy. There are no known contraindications related to soy in this medication.

B) Methylprednisolone (Solumedrol): This is a corticosteroid used to reduce inflammation. It is not contraindicated for clients with a soybean allergy, as it does not contain soy-derived components. The medication primarily poses risks related to long-term use, but not specifically regarding soybean allergies.

C) Ipratropium bromide (Atrovent): This medication is an anticholinergic used to relieve bronchospasm. Ipratropium bromide is formulated with soy lecithin, which is derived from soybeans. Therefore, it is contraindicated for clients with a known allergy to soybeans, as it may trigger an allergic reaction.

D) Albuterol (Ventolin): This medication is a short-acting beta-agonist used for quick relief of bronchospasm. It does not contain any soy components and is generally safe for patients with soybean allergies. While there may be other considerations for its use, the allergy to soy is not a concern with this medication.
