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 Prednisone. Which of the following instructions should be included in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take this medication with food.
• D. Decrease your intake of sodium-rich foods.

Correct answer: A

Rationale: The correct answer is A: 'Increase your intake of potassium-rich foods.' Prednisone can lead to potassium depletion, making it important for clients to increase their intake of potassium-rich foods like bananas, oranges, and spinach to prevent potential complications. Choice B is incorrect because grapefruit juice can interact with certain medications, but it is not a specific concern with Prednisone. Choice C is incorrect as Prednisone can be taken with or without food. Choice D is also incorrect because there is no direct relationship between Prednisone and sodium-rich foods.

3. A client with chronic kidney disease has a new prescription for epoetin alfa. The nurse should instruct the client to increase dietary intake of which of the following substances?

• A. Iron
• B. Protein
• C. Potassium
• D. Sodium

Correct answer: A

Rationale: Patients with chronic kidney disease are often prescribed epoetin alfa to treat anemia. Epoetin alfa stimulates red blood cell production, increasing the body's demand for iron to support this process. Therefore, clients taking epoetin alfa should be advised to increase their dietary intake of iron-rich foods to meet the increased demand and prevent iron deficiency anemia. Choices B, C, and D are incorrect because while protein is essential for overall health, potassium and sodium intake may need to be restricted in clients with chronic kidney disease to manage electrolyte balance and blood pressure.

4. What instruction should the nurse give regarding the adverse effect of dry mouth associated with diphenhydramine for a client with poison ivy?

• A. Administer the medication with food.
• B. Chew on sugarless gum or suck on hard, sour candies.
• C. Place a humidifier at your bedside every evening.
• D. Discontinue the medication and notify your provider.

Correct answer: B

Rationale: The correct instruction for dry mouth associated with diphenhydramine is to chew on sugarless gum or suck on hard, sour candies. These actions stimulate saliva production, providing relief from dry mouth. Administering the medication with food (Choice A) may help reduce stomach upset but won't address dry mouth. Placing a humidifier at the bedside (Choice C) can help with dry air-related issues but won't specifically target dry mouth. Discontinuing the medication (Choice D) without consulting the provider is not recommended and may lead to inadequate treatment of poison ivy.

5. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take this medication with food.
• D. Decrease your intake of sodium-rich foods.

Correct answer: A

Rationale: The correct answer is A: "Increase your intake of potassium-rich foods." Prednisone is associated with potassium depletion, making it important for clients to increase their intake of potassium-rich foods to prevent potential imbalances. Foods such as bananas, oranges, and spinach are good sources of potassium. Choice B, "Avoid consuming grapefruit juice," is not directly related to Prednisone use. Choice C, "Take this medication with food," is a general instruction for many medications but not specific to Prednisone. Choice D, "Decrease your intake of sodium-rich foods," is not directly related to Prednisone's side effects.
