1. While teaching a client with a new prescription for Warfarin, which of the following statements by the client indicates a need for further teaching?

• A. I will avoid eating large amounts of green leafy vegetables.
• B. I will take my medication at the same time every day.
• C. I will increase my intake of foods high in potassium.
• D. I will report any signs of bleeding to my provider.

Correct answer: C

Rationale: The correct answer is C because Warfarin interacts with vitamin K, found in green leafy vegetables, not potassium. The client should avoid consuming large amounts of foods high in vitamin K to maintain the effectiveness of Warfarin therapy. Increasing potassium intake is not a concern related to Warfarin therapy, so this statement indicates a need for further teaching. Choices A, B, and D are all correct statements indicating good understanding of Warfarin therapy. Avoiding large amounts of green leafy vegetables helps prevent fluctuations in vitamin K levels, taking medication consistently maintains therapeutic levels, and reporting any signs of bleeding is essential for monitoring and managing potential side effects of Warfarin.

2. What is the primary use of lithium?

• A. Lower blood glucose
• B. Slow the heart rate
• C. Stabilize mood
• D. Heal ulcers

Correct answer: C

Rationale: The correct answer is C: Stabilize mood. Lithium is primarily used to stabilize mood, especially in conditions like bipolar disorder. It helps in reducing the frequency and severity of manic episodes, making it an essential medication for mood stabilization. Choices A, B, and D are incorrect as lithium is not used to lower blood glucose, slow the heart rate, or heal ulcers.

3. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

4. A healthcare professional is reviewing the medical history of a client who has a new prescription for Metformin to treat type 2 diabetes. Which of the following findings should the healthcare professional report to the provider?

• A. Hemoglobin A1C of 7.5%
• B. Creatinine level of 1.2 mg/dL
• C. BUN level of 18 mg/dL
• D. Liver function tests showing AST of 50 units/L

Correct answer: D

Rationale: The correct answer is D. Elevated AST levels in liver function tests should be reported to the provider when a client is prescribed Metformin due to the potential risk of hepatotoxicity associated with the medication. Elevated Hemoglobin A1C (choice A), Creatinine level within normal range (choice B), and BUN level within normal range (choice C) are not directly concerning when initiating Metformin therapy.

5. A healthcare provider is assessing a client who takes Lithium Carbonate for the treatment of Bipolar disorder. The provider should recognize which of the following findings as a possible indication of toxicity to this medication?

• A. Severe hypertension
• B. Coarse tremors
• C. Constipation
• D. Muscle spasm

Correct answer: B

Rationale: Coarse tremors are a common sign of Lithium toxicity. It is important for healthcare providers to monitor for this symptom as it indicates a potential overdose of the medication. Severe hypertension, constipation, and muscle spasms are not typically associated with Lithium toxicity. Severe hypertension is not a common sign of Lithium toxicity but rather a symptom of hypertensive crisis. Constipation is not a typical sign of Lithium toxicity but could be seen in other conditions. Muscle spasms are not specific to Lithium toxicity but can occur due to various reasons.
