A nurse is preparing to administer amoxicillin 250 mg PO. Available is amoxicillin oral suspension 125 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. Antacids: Antacids are generally used to neutralize stomach acid and can provide symptomatic relief for peptic ulcer disease (PUD). They are not typically contraindicated and can be part of the treatment regimen, although they do not address the underlying cause of PUD.
B. NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to irritate the gastric mucosa and can exacerbate or cause peptic ulcers by inhibiting the production of protective prostaglandins in the stomach lining. Patients with peptic ulcer disease should avoid NSAIDs to prevent further irritation and ulcer formation.
C. PPIs: Proton pump inhibitors (PPIs) are commonly prescribed to reduce gastric acid secretion and promote ulcer healing in peptic ulcer disease. They are a key component of the treatment regimen and not to be avoided unless there are specific contraindications.
D. H2-receptor blockers: H2-receptor blockers reduce stomach acid production and are used to treat and prevent peptic ulcers. They are an important part of the management strategy for PUD and are not typically contraindicated.

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.
