A nurse is preparing to administer amoxicillin 350 mg orally.
The available amoxicillin is 250 mg per 5 mL. How many mL should the nurse administer?
The Correct Answer is ["7"]
The nurse is preparing to administer amoxicillin 350 mg orally. The available amoxicillin is 250 mg per 5 mL.
Step 1: To find out how many mL the nurse should administer, we need to set up a proportion to calculate the dosage. The proportion is set up as follows: 350 mg (desired dose) : X mL (unknown quantity) = 250 mg (available dose) : 5 mL (known quantity)
Step 2: Cross-multiply to solve for X: 350 mg * 5 mL = 250 mg * X mL Step 3: Simplify the equation: 1750 mgmL = 250X mgmL Step 4: Divide both sides by 250 mg to solve for X: X = 1750 mg*mL ÷ 250 mg = 7 mL. So, the nurse should administer 7 mL of amoxicillin.

Correct Answer is ["A","C","D","E"]
Explanation
Smoking, Diabetes, Atherosclerosis, and Weak pedal pulses.
Factors that contribute to poor circulation to the limb include:
- Smoking: It can cause constriction and damage to the blood vessels, leading to poor circulation.
- Diabetes: High blood sugar levels can damage blood vessels and nerves, leading to poor circulation.
- Atherosclerosis: This is a condition where plaque builds up in the arteries, narrowing them and reducing blood flow.
- Weak pedal pulses: This can be a sign of reduced blood flow to the lower extremities. A sodium-restricted diet (Choice B) is not typically associated with poor circulation.
Correct Answer is D
Explanation
Choice A rationale
Phenytoin is an antiepileptic medication used to control seizures. It’s important for the patient to understand that they should not switch brands of this medication without consulting their healthcare provider. Different brands of phenytoin can have different effects, and switching could potentially lead to changes in seizure control.
Choice B rationale
Regular dental appointments are important for patients taking phenytoin. This medication can cause gum overgrowth (gingival hyperplasia), so good oral hygiene and regular dental check- ups are essential.
Choice C rationale
It’s crucial for patients to notify their doctor before taking any other medications. Phenytoin can interact with many other drugs, altering their effectiveness or increasing side effects.
Therefore, the patient’s statement indicates an understanding of the need for caution when considering additional medications.
Choice D rationale
Phenytoin is a long-term medication for controlling seizures. It’s not something that patients can stop taking once they feel better. Abruptly stopping the medication can lead to withdrawal
seizures. Therefore, the patient’s statement, “I’ll be glad when I can stop taking this medicine,” indicates a need for further teaching about the importance of continuing the medication as prescribed.
