alternative usage includes being the reversal agent for acetaminophen overdoses.

This medication should not be used for clients with productive coughs.

This medication has a foul smell resembling "rotten eggs"

This medication can be utilized in client's with cystic fibrosis. This medication falls under the classification of "mucoyltic".

Answer and Explanation

Correct Answer : A,C

A) Alternative usage includes being the reversal agent for acetaminophen overdoses: Acetylcysteine is indeed used as an antidote for acetaminophen toxicity. It helps replenish glutathione levels in the liver, thus protecting it from damage caused by the overdose. This is a well-established use of the medication.

B) This medication should not be used for clients with productive coughs: This statement is not correct. Acetylcysteine is used to help thin and loosen mucus, making it easier to expel from the lungs. It can be beneficial for clients with productive coughs, as it aids in reducing excessive respiratory secretions.

C) This medication has a foul smell resembling "rotten eggs": Acetylcysteine has a characteristic odor that is often described as similar to rotten eggs due to the presence of sulfur in its chemical structure. This can be an important consideration for patients when administering the medication.

D) This medication can be utilized in clients with cystic fibrosis. This medication falls under the classification of "mucolytic": Acetylcysteine is classified as a mucolytic agent, making it useful for patients with conditions like cystic fibrosis, where thick mucus production is a significant issue. It helps to decrease the viscosity of secretions, facilitating easier clearance.

E) This medication has anticholinergic properties and side effects: This statement is incorrect. Acetylcysteine does not possess anticholinergic properties. Anticholinergic medications typically reduce secretions and are used for different indications, whereas acetylcysteine serves to increase mucus clearance, not decrease it.

Correct Answer is C

Explanation

A. Inhibits the production of leukotrienes and histamine, preventing further asthma attacks: This statement is misleading. Omalizumab does not directly inhibit the production of leukotrienes or histamine; rather, it works by targeting IgE, which is involved in the allergic response.

B. Inhibits mast cells from releasing histamine, preventing further asthma attacks: While omalizumab does reduce the overall allergic response, it does so by binding to IgE rather than directly inhibiting mast cell activity. Therefore, this description does not accurately represent its primary mechanism of action.

C. Selectively binds to IgE, reducing allergic mediators and asthma attacks: This statement correctly describes the mechanism of action of omalizumab. By binding to immunoglobulin E (IgE), omalizumab prevents IgE from attaching to mast cells and basophils, thus reducing the release of allergic mediators that contribute to asthma attacks.

D. Stimulates alpha-adrenergic receptors to assist in reduction of allergic-related symptoms: This statement is incorrect. Omalizumab does not stimulate alpha-adrenergic receptors; such action is associated with certain bronchodilators. Omalizumab specifically targets IgE to mitigate allergic responses.

A. CNS Depressants B. Short acting Beta Agonist C. Monoamine oxidase inhibits D. Mast Cell inhibitors

Correct Answer is C

Explanation

A. CNS Depressants: While there may be general concerns about using multiple medications that affect the central nervous system, CNS depressants do not have a direct interaction with oxymetazoline. Oxymetazoline is primarily a nasal decongestant and its interactions are more specific to other classes of medications.

B. Short Acting Beta Agonist: Short-acting beta agonists (SABAs) are bronchodilators used in asthma management. There is no direct interaction with oxymetazoline; they are used for different purposes and act on different receptors.

C. Monoamine oxidase inhibitors (MAOIs): This option is correct. MAOIs can potentially interact with oxymetazoline, leading to increased blood pressure and other cardiovascular effects. The combination can cause vasoconstriction due to the stimulant effects of both oxymetazoline and the increased levels of norepinephrine resulting from MAOI inhibition.

D. Mast Cell Inhibitors: Mast cell stabilizers do not interact directly with oxymetazoline. These medications are used primarily to manage allergic responses and asthma symptoms and do not have a significant effect on the actions of oxymetazoline.
