A health care provider prescribes 50 mg of a drug. The drug is only available in a 20 mL vial that contains 20 mg/mL of the drug. How much solution must the nurse administer for each dose?
The Correct Answer is ["2.5"]
To calculate the amount of solution needed for each dose, we need to use the formula:
Amount of solution (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the given values, we get:
Amount of solution (mL) = 50 mg / 20 mg/mL
Simplifying, we get:
Amount of solution (mL) = 2.5 mL
Therefore, the nurse must administer 2.5 mL of the solution for each dose.

Correct Answer is ["3"]
Explanation
To calculate the dosage of furosemide (Lasix), a diuretic medication, you need to divide the ordered amount by the tablet strength.
In this case, the ordered amount is 120 mg and the tablet strength is 40 mg.
Therefore, you need to divide 120 by 40, which gives you 3.
This means you would administer 3 tablets of furosemide (Lasix) to the patient.
Correct Answer is A
Explanation
A. Misoprostol (Cytotec)
The patient complaining of gastric distress from NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) like aspirin or indomethacin may benefit from the administration of misoprostol (Cytotec). Misoprostol is a prostaglandin analog that helps protect the stomach lining and reduce the risk of NSAID-induced gastric ulcers.
B. Lansoprazole (Prevacid)
Lansoprazole is a proton pump inhibitor (PPI) that reduces stomach acid production. While PPIs can be used for certain acid-related conditions, they do not directly protect against NSAID-induced gastric distress.
C. Magaldrate (Riopan)
Magaldrate is an antacid that neutralizes stomach acid. It may provide relief from symptoms of indigestion but does not specifically address the gastric distress caused by NSAIDs.
D. Magnesium trisilicate (Gaviscon)
Magnesium trisilicate is an antacid that helps neutralize stomach acid. Like magaldrate, it may alleviate symptoms of indigestion but does not target the underlying issue of NSAID-induced gastric distress.
