The order reads "amoxicillin 20mg/kg/dose PO every 8 hours." The child weighs 33 pounds. Using the label below, how many mL will you administer per dose? (Enter a number only, answer to the nearest tenths place)
The Correct Answer is ["12"]
1. Convert the child's weight from pounds to kilograms:
There are approximately 2.2 pounds in 1 kilogram.
33 pounds / 2.2 pounds/kg = 15 kg (approximately)
2. Calculate the total milligrams of amoxicillin needed per dose:
The order is for 20 mg/kg/dose.
The child weighs 15 kg.
20 mg/kg * 15 kg = 300 mg
3. Determine the concentration of the amoxicillin suspension:
The label shows the concentration is 125 mg/5 mL.
4. Set up a proportion to find the volume (in mL) needed:
125 mg / 5 mL = 300 mg / x mL
5. Solve for x:
Cross-multiply: 125x = 300 * 5
125x = 1500
x = 1500 / 125
x = 12 mL
Answer: You will administer 12 mL per dose.

Correct Answer is A
Explanation
CYP 450 enzymes are responsible for the metabolism of many drugs. Smoking can induce certain CYP 450 enzymes, particularly CYP1A2, which leads to an increase in the metabolism of drugs that are substrates of this enzyme. When a person begins smoking, the induction of these enzymes can cause drugs to be metabolized more quickly, which typically results in lower drug levels in the body. However, the statement asks whether the level of medication will increase in this client, and since smoking induces enzyme activity, it would typically lead to decreased, not increased, drug levels. However, in the context of drug-drug interactions and other metabolic pathways, the metabolism rate could be altered in ways that might increase or affect the therapeutic response.
Correct Answer is C
Explanation
A) "I know it is really busy but I do not have time to help you either. I have my own clients.": While it may be tempting to express frustration due to being busy, this response lacks professionalism and does not address the situation appropriately. As healthcare professionals, it is important to communicate effectively and collaborate with colleagues to ensure safe patient care, even when busy. Instead, the nurse should express the need to follow protocols while offering help in a safe manner.
B) "Are you sure the doctor ordered that much morphine? It seems like a lot to give all at once.": Although questioning the dosage is part of safe nursing practice, this response is unnecessary in this situation. If there is a concern about the prescribed amount of morphine, it should be verified with the healthcare provider. However, this question does not directly address the issue of administering the medication safely. It also does not ensure that the nurse is following correct protocols for preparing and administering medication.
C) "I can give your client their pain medications, but I need to draw up and prepare it myself.": This response is the most appropriate because it ensures the nurse is adhering to safe medication administration practices. The nurse should always prepare and administer medications themselves to verify the correct dosage, route, and patient. Allowing another nurse to prepare medication and administering it without proper verification can lead to medication errors. This response also shows willingness to help while maintaining safety standards.
D) "Sure thing, give me that syringe and I will give it for you while you are on break.": This response is inappropriate because it involves accepting medication from another nurse without verifying that the correct drug, dose, and preparation have been followed. It is unsafe to administer medications prepared by others without reviewing the medication and ensuring that everything is accurate. Nurses must always prepare and administer their own medications to prevent potential medication errors.
