Nursing Elites

1. How should a healthcare professional respond to a patient with hypokalemia?

• A. Administer potassium supplements and monitor ECG
• B. Restrict fluid intake and provide a high-sodium diet
• C. Monitor sodium levels and provide insulin therapy
• D. Provide calcium supplements and monitor for hyperkalemia

Correct answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.

2. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

3. A nurse is reinforcing teaching about food selection with a client who has a moderate burn injury. Which of the following foods should the nurse recommend as being high in vitamin C?

• A. Tomatoes
• B. Carrots
• C. Avocados
• D. Apricots

Correct answer: A

Rationale: Tomatoes are high in vitamin C, which is crucial for wound healing, making them an excellent recommendation for a client with a burn injury. Carrots, avocados, and apricots are not as rich in vitamin C compared to tomatoes, and therefore, they are not the best choice for promoting healing in this scenario.

4. What are the major risk factors for stroke?

• A. Hypertension, high cholesterol, and smoking
• B. Obesity and lack of exercise
• C. Family history of cardiovascular disease
• D. Age and gender

Correct answer: A

Rationale: The correct answer is A: Hypertension, high cholesterol, and smoking are major risk factors for stroke. These factors contribute to the development of atherosclerosis, which can lead to a stroke. While obesity and lack of exercise are risk factors for cardiovascular diseases, they are not as directly linked to stroke as hypertension, high cholesterol, and smoking. Family history of cardiovascular disease may increase the overall risk of heart problems, but it is not as specific to stroke as the factors listed in option A. Age and gender can influence the risk of stroke, but they are not modifiable risk factors like hypertension, high cholesterol, and smoking, which can be reduced through lifestyle changes.

5. A client has a prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include in the teaching?

• A. Place the tablet under the tongue and wait 10 minutes
• B. Take up to five tablets during an angina episode
• C. Take up to three tablets during a single angina episode
• D. Swallow the tablet with water

Correct answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.
