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.

Explanation
The purpose of the stool guaiac test, also known as the fecal occult blood test (FOBT), is to identify the presence of hidden or occult blood in the stool. This test is commonly performed to screen for gastrointestinal bleeding, which can indicate various conditions such as colorectal cancer, ulcers, polyps, or other sources of bleeding in the digestive tract.
The other options mentioned are not specifically detected by the stool guaiac test:
Parasites: The stool guaiac test does not directly detect parasites in the feces. Parasite testing requires a different type of analysis, such as microscopic examination or specialized laboratory tests.
Bacteria: The stool guaiac test does not specifically detect bacteria in the feces. If a bacterial infection is suspected, other diagnostic tests such as stool culture or polymerase chain reaction (PCR) may be ordered.
Fat: The stool guaiac test is not designed to detect fat in the feces. If there is a concern about fat malabsorption, other tests such as fecal fat analysis or Sudan stain may be used.
Correct Answer is A
Explanation
When reinforcing teaching with a client who has a new prescription for aluminum hydroxide to treat heartburn, the nurse should include constipation as an adverse effect of the medication. Aluminum hydroxide is an antacid commonly used to neutralize stomach acid and provide relief from heartburn and indigestion. However, one of its potential side effects is constipation. Aluminum hydroxide can slow down intestinal motility, leading to infrequent or difficult bowel movements.
Hypertension: Aluminum hydroxide is not known to cause hypertension (high blood pressure). However, clients with pre-existing hypertension should be cautious when using antacids containing sodium bicarbonate, as the sodium content may impact blood pressure levels.
Flatulence: Flatulence (excessive gas) is not a common adverse effect of aluminum hydroxide. It primarily works by neutralizing stomach acid and does not typically cause increased gas production.
Headache: Headache is not commonly reported as an adverse effect of aluminum hydroxide. It is more likely to be associated with other factors such as the underlying condition causing heartburn or individual factors.
