A client is on a blood thinner medication and requires weekly INR values. The nurse expects to see an INR of 2-2.5 times the normal range so she would anticipate what value:
below 1.0
1.0-2.0
above 3.0
2.0-3.0
The Correct Answer is D
A. Below 1.0: Too low, indicating inadequate anticoagulation, increasing the risk of clot formation.
B. 1.0-2.0: Subtherapeutic, meaning the medication is not effectively preventing clot formation.
C. Above 3.0: Too high, increasing the risk of bleeding complications
D. 2.0-3.0: The normal INR (International Normalized Ratio) for a client not on anticoagulants is 0.8-1.2. For clients on warfarin or other blood thinners, the target therapeutic range is typically 2.0-3.0, which reduces the risk of blood clots while minimizing the risk of bleeding. Some conditions, such as mechanical heart valves, may require a higher target range (2.5-3.5).

Correct Answer is B
Explanation
A. "Alcohol is metabolized in the kidneys." Alcohol is primarily metabolized in the liver, not the kidneys.
B. "Alcohol can increase the chances of nephrotoxicity." Chronic alcohol use can damage the kidneys and increase the risk of nephrotoxicity, especially when combined with nephrotoxic drugs (e.g., NSAIDs, aminoglycosides).
C. "Alcohol can decrease the chance of medication side effects." Alcohol can actually enhance medication side effects, such as sedation with CNS depressants or liver damage with acetaminophen.
D. "Medication can be metabolized faster when alcohol is consumed regularly." Chronic alcohol use induces liver enzymes, potentially altering metabolism, but it does not necessarily speed up drug metabolism for all medications.
Correct Answer is B
Explanation
A. Notify the nurse manager: Reporting is important, but assessing the patient comes first.
B. Observe the client and collect data: Patient safety is the priority. The nurse must assess the client for adverse effects first before notifying anyone.
C. Call the client’s provider: The provider needs to be informed, but only after assessing the client’s condition.
D. Complete an incident report: Documentation is essential but comes after assessing and ensuring client safety.
