A client currently prescribed a medication highly metabolized by the CYP 450 recently began smoking due to a stressful life event. True or False: The level of medication will increase in this client.
True
False
The Correct Answer is A
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 B
Explanation
A) Failed communication: While communication errors can lead to medication mistakes, in this specific scenario, there is no mention of poor communication. The prescription is clear, and the issue is more likely related to the accuracy of the prescribed dose or the nurse’s understanding of it, making "failed communication" a less likely source of error in this case.
B) Dose miscalculation: This is the most likely source of potential error. The medication is ordered as 0.9 mg of ondansetron IV, which is an unusual dosage because the typical dose of ondansetron IV for nausea is usually 4 mg or 8 mg. A dose of 0.9 mg is very specific and could easily be miscalculated, especially if the nurse is not familiar with this specific dosage form or if there’s any confusion regarding the intended dose. This could lead to an error either in preparation or administration of the medication.
C) Lack of client education: While client education is important for many aspects of treatment, it’s not directly related to the potential medication error in this scenario. The nurse’s concern should focus on the accuracy of administering the prescribed dose correctly, not the client’s understanding of the medication.
D) Poor distribution practices: Poor distribution practices may affect the availability or storage of medications, but this is not the likely source of error in this case. The concern here is more about the correct dosage and potential for miscalculation, rather than issues related to drug distribution or storage.
Correct Answer is ["250"]
Explanation
Identify the total volume:
The client is ordered to receive 1000 mL of 0.9% saline.
Identify the infusion time:
The infusion time is 4 hours.
Set up the calculation:
We need to find out the IV pump rate in mL/hr. We can use the following formula:
(Total volume) / (Infusion time) = IV pump rate
4. Plug in the values and calculate:
(1000 mL) / (4 hours) = 250 mL/hr
