Nursing Elites

1. 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.

2. A client has a new prescription for Allopurinol. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Increase your fluid intake.
• C. Avoid foods high in calcium.
• D. Take this medication with meals.

Correct answer: B

Rationale: Allopurinol can cause kidney stones due to the formation of uric acid crystals, so it is crucial for the client to increase their fluid intake. Adequate hydration helps to prevent the formation of kidney stones by diluting the urine and promoting the excretion of uric acid. Therefore, advising the client to increase their fluid intake is essential in preventing this adverse effect while taking Allopurinol.

3. A client is taking Furosemide for heart failure. Which of the following findings is a priority to report to the provider?

• A. Weight loss of 1 kg in 24 hours
• B. Blood pressure of 104/60 mm Hg
• C. Potassium level of 3.5 mEq/L
• D. Urine output of 200 mL in 8 hours

Correct answer: D

Rationale: A urine output of 200 mL in 8 hours indicates decreased kidney function and potential worsening heart failure. This finding should be reported promptly to the provider for further evaluation and management to prevent complications. Weight loss, while significant, may be expected with diuretic use. A blood pressure of 104/60 mm Hg is within normal range and can be managed. A potassium level of 3.5 mEq/L is slightly low but not an immediate concern.

4. A client is prescribed levothyroxine for hypothyroidism. Which of the following findings should indicate to the nurse that the medication is effective?

• A. Decreased heart rate
• B. Increased energy levels
• C. Weight loss
• D. Improved mental clarity

Correct answer: B

Rationale: Increased energy levels are a key indicator of the effectiveness of levothyroxine in treating hypothyroidism. Levothyroxine works to regulate thyroid hormone levels, which can lead to improved energy levels as the body's metabolism is restored. While the other options may also improve with treatment, increased energy levels directly reflect the correction of the thyroid hormone imbalance. Decreased heart rate can be an indicator of overmedication, weight loss can be attributed to increased metabolism but may not directly reflect the effectiveness of levothyroxine, and improved mental clarity is a more general cognitive improvement that may not directly relate to thyroid function.

5. A client with Atrial Fibrillation is prescribed Dabigatran to prevent Thrombosis. Which medication is prescribed concurrently to treat an adverse effect of Dabigatran?

• A. Vitamin K1
• B. Protamine
• C. Omeprazole
• D. Probenecid

Correct answer: C

Rationale: Omeprazole, a proton pump inhibitor, is prescribed for clients taking dabigatran who experience abdominal pain and other gastrointestinal adverse effects associated with dabigatran use. Proton pump inhibitors help manage these symptoms effectively. Choice A, Vitamin K1, is incorrect as it antagonizes the activity of Dabigatran, counteracting its anticoagulant effect. Choice B, Protamine, is used to reverse the anticoagulant effects of heparin, not dabigatran. Choice D, Probenecid, is not typically used to treat adverse effects of dabigatran.
