A nurse is caring for a client who presents with chronic obstructive pulmonary disorder (COPD), Which of the following task can the nurse delegate to the UAP?

A) Administer albuterol via inhalation device to the client: This task cannot be delegated to the unlicensed assistive personnel (UAP). Administering medications, especially inhaled bronchodilators like albuterol, requires a licensed nurse to ensure proper technique, monitor the client for adverse effects, and assess the effectiveness of the treatment.

B) Performing initial respiratory assessment to determine baseline respiratory rate: This task also cannot be delegated to the UAP. Assessing respiratory status, including determining baseline respiratory rate and identifying any abnormalities, requires critical thinking and clinical judgment that a nurse must perform.

C) Assist the client with oral hygiene following inhaled corticosteroid administration by the nurse: This task can be delegated to the UAP. Assisting with oral hygiene is within the scope of practice for UAPs, and it is essential after administering inhaled corticosteroids to help prevent oral thrush and maintain oral health.

D) Assess the client's lung sounds to determine if wheezing is present: This task cannot be delegated to the UAP. Assessing lung sounds is a critical nursing assessment that requires the knowledge and skills of a licensed nurse to interpret findings and make clinical decisions based on the assessment.

A) Cetirizine (Zyrtec): This medication is classified as a second-generation antihistamine. Second-generation antihistamines are designed to be less sedating than first-generation agents, as they are less likely to cross the blood-brain barrier. Cetirizine effectively alleviates symptoms of allergic rhinitis by blocking histamine receptors and is commonly used due to its efficacy and reduced sedation compared to older antihistamines.

B) Chlorpheniramine (Aller-Chlor): Chlorpheniramine is a first-generation antihistamine. It tends to cause more sedation and has a higher likelihood of causing side effects such as drowsiness, dry mouth, and dizziness. First-generation antihistamines are typically less selective and can affect the central nervous system more significantly than their second-generation counterparts.

C) Diphenhydramine (Benadryl): This medication is also a first-generation antihistamine. It is well-known for its sedative effects and is often used for allergic reactions, as well as for its sleep-inducing properties. Like other first-generation antihistamines, diphenhydramine can cause significant drowsiness and other anticholinergic effects.

D) Montelukast (Singulair): Montelukast is not an antihistamine but rather a leukotriene receptor antagonist. It is used for the management of allergic rhinitis and asthma but works through a different mechanism by blocking leukotriene receptors, thereby reducing inflammation and mucus production. It is not classified as an antihistamine, either first or second generation.
