A nurse is preparing to administer prednisone 40 mg PO to an adolescent client. Available is prednisone oral solution 5 mg/5 mL. How many ml. should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Take albuterol first. Albuterol is a short-acting beta-agonist (SABA) that acts quickly to dilate the airways. It should be taken first to open the airways, making it easier for the long-acting beta-agonist (LABA), salmeterol, to penetrate deeper into the lungs and provide prolonged bronchodilation.
B. The order of administration does not matter. This is incorrect because the sequence does matter. Taking albuterol first helps to maximize the effectiveness of the subsequent medication by improving airway openness.
C. They should not be taken together: This is incorrect. Albuterol and salmeterol can be used together as part of asthma management. They work through different mechanisms, and using them together can provide both quick relief and long-term control.
D. Take salmeterol first: Taking salmeterol first is not recommended because it is a long-acting bronchodilator that works slowly. The immediate relief provided by albuterol helps to open the airways first, making the use of salmeterol more effective.

A. Cetirizine (Zyrtec): Cetirizine is an antihistamine used to treat mild allergic reactions, such as seasonal allergies or mild hives. It is not the treatment of choice for severe allergic reactions like anaphylaxis, which this patient may be experiencing given the symptoms and history of peanut allergy.
B. Diphenhydramine (Benadryl): Diphenhydramine is an antihistamine that can be used for mild to moderate allergic reactions, including urticaria and mild anaphylaxis. While it may be part of anaphylactic treatment, it is not the primary treatment for severe symptoms like difficulty breathing.
C. Guaifenesin: Guaifenesin is an expectorant used to relieve chest congestion and make coughs more productive. It is not appropriate for treating allergic reactions or respiratory distress related to anaphylaxis.
D. Epinephrine: Epinephrine is the first-line treatment for anaphylaxis, which is a severe and potentially life-threatening allergic reaction. It works by rapidly reducing airway swelling, improving breathing, and stabilizing blood pressure. Given the patient's symptoms and history of peanut allergy, epinephrine is the most appropriate medication.
