The nurse is providing teaching to a client who is being discharged with a prescription for warfarin. Which information should be included in the teaching for this medication?
Omit green, leafy vegetables from the diet.
Use over-the-counter pain relief medications.
Obtain laboratory tests as directed.
Use an electric razor for shaving.
Obtain a medical alert bracelet.
The Correct Answer is C
Choice A rationale
While it is true that warfarin’s effectiveness can be affected by vitamin K, found in green leafy vegetables, it is not necessary to completely omit these from the diet. Instead, maintaining a consistent intake of vitamin K can help keep INR levels stable.
Choice B rationale
Over-the-counter pain relief medications, especially those that are nonsteroidal anti- inflammatory drugs (NSAIDs), can increase the risk of bleeding when taken with warfarin. Therefore, this advice is not correct.
Choice C rationale
Regular laboratory tests, specifically the International Normalized Ratio (INR), are crucial when taking warfarin to monitor its effectiveness and adjust the dosage if necessary.
Choice D rationale
Using an electric razor can help prevent cuts and bleeding, which is important because warfarin is a blood thinner. However, this information is not as critical as obtaining regular laboratory tests.
Choice E rationale
Obtaining a medical alert bracelet can be beneficial for individuals taking warfarin, as it can alert healthcare professionals in an emergency situation about the individual’s use of a blood thinner. However, this information is not as critical as obtaining regular laboratory tests.

Correct Answer is C
Explanation
Choice A rationale
Limiting intake to non-caloric containing liquids until the glucose is within normal limits is not the best advice for a patient with Type 1 diabetes reporting a blood glucose level of 210 mg/dL and symptoms of a sore throat, cough, and fever. While it’s important to stay hydrated, especially when sick, it’s also crucial to maintain a balanced diet to provide the body with necessary nutrients for recovery.
Choice B rationale
Decreasing intake of carbohydrates until blood glucose level is less than 100 mg/dL is not recommended. Carbohydrates are a primary source of energy, and reducing their intake could lead to low blood sugar or hypoglycemia, which can be dangerous.
Choice C rationale
Monitoring blood glucose levels every 4 hours and notifying the doctor if it continues to rise is the best advice. When a patient with diabetes is sick, their blood glucose levels can rise due to the stress the body is under. Regular monitoring allows for timely adjustments in insulin dosage and helps prevent diabetic ketoacidosis, a serious complication.
Choice D rationale
Administering only the morning prescribed dose of insulin is not advisable. Insulin requirements can increase when a person with diabetes is sick. Therefore, sticking to the regular insulin regimen without adjustments could lead to high blood sugar or hyperglycemia.
Correct Answer is A
Explanation
Choice A rationale
Dark urine can be a sign of liver dysfunction, which can be a side effect of glipizide. Therefore, reviewing the results of liver function studies would be an appropriate initial action to determine if the medication is affecting the client’s liver function.
Choice B rationale
While increasing water intake can sometimes help with certain side effects of medications, it would not address the potential issue of liver dysfunction indicated by the dark urine.
Choice C rationale
Checking the client’s weight would not provide information related to the cause of the dark urine.
Choice D rationale
Testing a sample of urine for the presence of occult blood could be useful if there was a suspicion of bleeding, but it would not address the potential issue of liver dysfunction indicated by the dark urine.
