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
Sucralfate is a medication commonly used in the treatment of peptic ulcer disease. It works by forming a protective barrier over the ulcer site, providing a physical barrier against gastric acid, and promoting the healing process. When teaching a client about sucralfate, it is important to provide instructions regarding its proper administration.
One of the key instructions is to take sucralfate 1 hour before meals. This timing allows the medication to form a protective coating in the stomach before food is ingested. Taking sucralfate on an empty stomach enhances its effectiveness in protecting the ulcer and promoting healing.
"Take the medication with an antacid" - Sucralfate should not be taken with an antacid. Antacids can interfere with the protective mechanism of sucralfate by neutralizing stomach acid, which is necessary for sucralfate to bind and form a protective coating. It is recommended to wait at least 30 minutes to 1 hour after taking sucralfate before taking an antacid.
"Take as needed for pain relief" - Sucralfate is not typically used for immediate pain relief in peptic ulcer disease. It is primarily used for its protective and healing properties. Pain relief is
usually addressed with other medications, such as antacids, acid-reducing medications, or pain medications as prescribed by a healthcare provider.
"Store the medication in the refrigerator" - Sucralfate does not require refrigeration. It should be stored at room temperature, away from excessive heat or moisture, as per the specific instructions provided by the manufacturer or healthcare provider.
Correct Answer is B
Explanation
Atenolol is a beta-blocker medication commonly used to treat conditions such as hypertension (high blood pressure) and certain heart rhythm disorders. One of the intended effects of atenolol is to lower the heart rate by blocking the action of adrenaline on beta receptors in the heart. However, this can sometimes result in bradycardia, which refers to a heart rate that is slower than the normal range.
Hypokalemia, or low potassium levels, is not directly caused by atenolol but can be an indirect effect. Beta-blockers like atenolol can potentially interfere with the normal release of insulin and contribute to increased urinary excretion of potassium. Therefore, it's important to monitor potassium levels in clients taking atenolol, as low potassium levels can have adverse effects on various body systems.
Anemia and neutropenia are not typically associated with the use of atenolol. Anemia refers to a decrease in the number of red blood cells or a decrease in the amount of hemoglobin, which carries oxygen to the body tissues. Neutropenia refers to a decrease in the number of neutrophils, which are a type of white blood cell involved in fighting infection.
