A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (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 ["500"]
To calculate the dose of erythromycin per administration, you can follow these steps:
- Determine the total daily dose: 2 g.
- Divide the total daily dose by the number of equally divided doses per day: 2 g / 4 doses =
0.5 g per dose.
- Convert grams to milligrams: 0.5 g * 1000 mg/g = 500 mg.
So, the nurse should administer 500 mg of erythromycin per dose.

Correct Answer is A
Explanation
A. This statement indicates correct understanding. Remaining upright after taking ferrous gluconate reduces the risk of esophageal irritation or discomfort, which can occur if the medication refluxes into the esophagus. This is an important teaching point for clients taking iron supplements.
B. This statement is incorrect. Antacids can interfere with the absorption of ferrous gluconate by altering stomach acidity, which is necessary for optimal iron absorption. Clients should avoid taking antacids within two hours of iron supplements.
C. This statement is incorrect. Milk and other calcium-containing products inhibit the absorption of iron. It is recommended to take ferrous gluconate with water or a source of vitamin C, such as orange juice, to enhance absorption.
D. This statement is incorrect. Black stools are a common and harmless side effect of taking iron supplements and do not typically require notifying the provider unless accompanied by other symptoms like abdominal pain or blood in the stool.
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"A"},"D":{"answers":"A"},"E":{"answers":"A"}}
Explanation
Taking the medication with orange juice (a) is advisable as vitamin C can enhance iron absorption
Notifying the provider about black stools is appropriate because it can indicate gastrointestinal bleeding, a potential side effect of ferrous sulfate.
Avoiding antacids while on ferrous sulfate is important because they can decrease the absorption of iron, so this statement demonstrates understanding.
Rinsing the mouth after taking ferrous sulfate can help prevent staining of the teeth, indicating understanding.
Taking the medication on an empty stomach enhances its absorption, so not understanding this instruction suggests a lack of comprehension.
