A nurse is preparing to administer liquid famotidine 20 mg PO every 6 hr for GERD. Available is famotidine 40 mg/5 ml. How many ml. should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
To determine how many milliliters (ml) should be administered per dose, we need to calculate the dose volume using the available concentration of famotidine.
Given:
Famotidine concentration: 40 mg/5 ml
Dose: 20 mg
We can set up a proportion to solve for the volume:
40 mg / 5 ml = 20 mg / x ml
Cross-multiplying the proportion, we get:
40 mg * x ml = 20 mg * 5 ml
Simplifying, we have:
40x = 100
Dividing both sides by 40, we find:
x = 100 / 40
x ≈ 2.5 ml
Therefore, the nurse should administer approximately 2.5 ml of famotidine per dose.

Correct Answer is B
Explanation
After administering lactulose to a client with cirrhosis, the nurse should monitor for the adverse effects of diarrhea. Lactulose is a laxative commonly used in the treatment of hepatic encephalopathy, which can occur in individuals with cirrhosis. One of the intended effects of lactulose is to promote bowel movements and reduce the absorption of ammonia in the gut, thus helping to manage hepatic encephalopathy.
While lactulose can cause adverse effects such as diarrhea, it is not typically associated with peripheral edema. Peripheral edema is often seen in cirrhosis due to fluid retention caused by liver dysfunction.
Dry mouth and headache are less commonly associated with lactulose use and are not typically the primary adverse effects to monitor for in this scenario.
Correct Answer is A
Explanation
Sucralfate is a medication used to treat peptic ulcers by forming a protective coating on the stomach lining. It should be taken on an empty stomach, as food can interfere with its absorption and effectiveness. One hour before breakfast and the evening meal is the correct timing for administering sucralfate, allowing for an empty stomach before meals.
At the time the client takes a proton pump inhibitor: Proton pump inhibitors are a different class of medications used to reduce stomach acid production. It is recommended to administer sucralfate separately, as it works differently and has different administration requirements.
Thirty minutes after breakfast and the evening meal: Administering sucralfate after meals is not ideal, as it may not provide the desired therapeutic effect on an empty stomach.
The time the client takes an antacid: Antacids are also different from sucralfate, and they can interfere with its absorption. It is generally recommended to administer sucralfate separately from antacids.
