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 Levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Take this medication on an empty stomach.
• D. Take this medication with antacids.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption, affecting the medication's effectiveness.

3. A healthcare provider is caring for a client who has a new prescription for Clonidine. Which of the following adverse effects should the healthcare provider monitor?

• A. Drowsiness
• B. Dry mouth
• C. Weight gain
• D. Insomnia

Correct answer: B

Rationale: The correct answer is B: Dry mouth. Dry mouth is a common adverse effect of Clonidine. Clonidine can cause a reduction in salivary flow, leading to dry mouth. This symptom can be managed by increasing fluid intake or using sugar-free gum or candy to stimulate saliva production. Choices A, C, and D are incorrect. While drowsiness and insomnia are potential side effects of Clonidine, dry mouth is more commonly reported. Weight gain is not typically associated with Clonidine use.

4. A client has a prescription for Phenytoin. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Increase your intake of calcium-rich foods.
• C. Brush and floss your teeth regularly.
• D. Avoid eating foods high in potassium.

Correct answer: C

Rationale: The correct answer is C: 'Brush and floss your teeth regularly.' Phenytoin can cause gingival hyperplasia, a condition that leads to overgrowth of gum tissue. Good oral hygiene practices such as regular brushing and flossing can help prevent or minimize this side effect. In contrast, choices A, B, and D are not directly related to managing the side effects of Phenytoin. Taking the medication at bedtime (choice A) is not a specific instruction related to oral hygiene. Increasing calcium-rich foods intake (choice B) may be beneficial for bone health but is not directly related to preventing gingival hyperplasia. Avoiding foods high in potassium (choice D) is not a necessary instruction for a client taking Phenytoin.

5. A client has a prescription for Furosemide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase your intake of potassium-rich foods.
• C. Expect your urine to turn orange.
• D. Avoid prolonged sunlight exposure.

Correct answer: B

Rationale: The correct answer is B: 'Increase your intake of potassium-rich foods.' Furosemide is a loop diuretic that can lead to hypokalemia (low potassium levels) due to increased excretion of potassium in the urine. To counteract this effect and maintain electrolyte balance, the client should be advised to increase their intake of potassium-rich foods. This instruction helps prevent potential complications associated with low potassium levels. Choices A, C, and D are incorrect. Taking Furosemide in the morning does not affect its effectiveness; urine turning orange is not an expected side effect of Furosemide; and avoiding prolonged sunlight exposure is not directly related to Furosemide use.
