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.)
The Correct Answer is ["250"]
Desired Dose=250mg
Available Concentration=125mg/5mL
Volume to Administer=Desired Dose/Available Concentration × Volume
= 250 mg ÷ 125 mg/5mL
= 250/125 × 5mL
= 2 ×5mL
= 10 mL
So, the nurse should administer 10 mL.

Correct Answer is B
Explanation
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.
Correct Answer is ["40"]
Explanation
Available solution: 5 mg/5 mL
Dosage required: 40 mg
To find out how many milliliters to administer, use the formula:
Volume(mL)= Doserequired(mg) ÷ Concentration(mg/mL)
Concentration=5mg÷5mL=1mg/mL
Volume(mL)=40mg÷1mg/mL=40mL
Therefore, the nurse should administer 40 mL.
