Question 1 of 5
Which of the following should the nurse include when providing dietary teaching for the patient receiving warfarin (Coumadin) therapy?
Correct Answer: A
Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin therapy. Green tea is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Maintaining a consistent intake of vitamin K is important for patients on warfarin in order to keep their INR (International Normalized Ratio) levels stable. It is not necessary to avoid all sources of vitamin K, but rather to keep intake consistent and moderate. Drinking large amounts of green tea, which is high in vitamin K, can potentially impact the patient's INR levels and increase the risk of bleeding or clotting issues.

Question 3 of 5
Mandy, a patient, calls the clinic today because he is taking atorvastatin (Lipitor) to treat his high cholesterol and is having pain in both of his legs. You instruct him to:
Correct Answer: A
Rationale: In this scenario, with the patient experiencing leg pain while taking atorvastatin (Lipitor), a medication commonly used to treat high cholesterol, it is essential to prioritize the patient's safety and well-being. Leg pain can be a sign of a rare but serious side effect known as rhabdomyolysis, which can lead to muscle breakdown and potentially affect kidney function. Therefore, it is crucial to immediately discontinue the medication (atorvastatin) and have the patient come in to the clinic to be seen today for further evaluation and management. This will allow healthcare providers to assess the severity of the leg pain, conduct necessary tests, and determine the appropriate course of action to ensure the patient's health and safety.
Question 4 of 5
When taking Digoxin, low levels of what can cause toxicity?
Correct Answer: A
Rationale: When taking Digoxin, low levels of potassium can cause toxicity because digoxin competes with potassium for binding sites on the sodium-potassium pump in cardiac cells. Low potassium levels can lead to increased binding of digoxin to the pump, resulting in increased intracellular calcium levels and an increased risk of digoxin toxicity, including arrhythmias. Therefore, monitoring and maintaining adequate potassium levels are crucial in patients taking digoxin to prevent toxicity.
Question 5 of 5
How would you evaluate the medical effectiveness of Metformin?
Correct Answer: A
Rationale: To evaluate the medical effectiveness of Metformin, it is essential to monitor serum glucose levels, as Metformin is commonly used to treat type 2 diabetes by decreasing glucose production in the liver and increasing insulin sensitivity in peripheral tissues. Monitoring serum electrolytes, ketones, blood pH, lactate, and pyruvate levels is also important because Metformin can potentially cause lactic acidosis, especially in patients with kidney or liver impairment. By assessing these parameters, healthcare providers can gauge the efficacy and safety of Metformin therapy. Checking for resolution of hypothyroidism and hormone normalization is not directly related to evaluating Metformin's effectiveness. Pain reduction and patient alertness are also not the primary indicators for assessing the medical effectiveness of Metformin in managing diabetes.
