Nursing Elites

1. A patient has a serum potassium level of 2.7 mEq/L. The patient’s provider has determined that the patient will need 200 mEq of potassium to replace serum losses. How will the nurse caring for this patient expect to administer the potassium?

• A. As a single-dose 200 mEq oral tablet
• B. As an intravenous bolus over 15 to 20 minutes
• C. In an intravenous solution at a rate of 10 mEq/hour
• D. In an intravenous solution at a rate of 45 mEq/hour

Correct answer: C

Rationale: For a patient with severe hypokalemia with a serum potassium level of 2.7 mEq/L requiring 200 mEq of potassium replacement, the appropriate route of administration would be intravenous. Potassium chloride should be administered slowly to prevent adverse effects; therefore, the correct option is to administer the potassium in an intravenous solution at a rate of 10 mEq/hour. Choices A and B are incorrect because potassium should not be given as a single-dose oral tablet or as an intravenous bolus over a short period of time due to the risk of adverse effects. Choice D is also incorrect as the rate of 45 mEq/hour exceeds the recommended maximum infusion rate for adults with a serum potassium level greater than 2.5 mEq/L, which is 10 mEq/hour.

2. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client's respiratory acidosis?

• A. Carbon dioxide is converted in the kidneys for elimination.
• B. Blood oxygen levels are stimulating the respiratory rate.
• C. Hyperventilation is eliminating carbon dioxide rapidly.
• D. High levels of carbon dioxide have accumulated in the blood.

Correct answer: D

Rationale: The correct answer is D. High levels of carbon dioxide in the blood are indicative of respiratory acidosis, often due to inadequate ventilation. In respiratory acidosis, there is retention of carbon dioxide (hypercapnia) leading to an increase in carbonic acid levels in the blood, resulting in an acidic pH. Option A is incorrect because carbon dioxide elimination primarily occurs through the lungs, not the kidneys. Option B is incorrect because blood oxygen levels primarily affect the respiratory rate to regulate oxygen levels, not carbon dioxide levels. Option C is incorrect because hyperventilation would lead to a decrease, not an increase, in carbon dioxide levels.

3. An obese client with emphysema who smoked at least a pack of cigarettes daily is admitted after experiencing a sudden increase in dyspnea and activity intolerance. Oxygen therapy is initiated, and it is determined that the client will be discharged with oxygen. Which information is most important for the nurse to emphasize in the discharge teaching plan?

• A. Methods for weight loss
• B. Guidelines for oxygen use
• C. Approaches to conserve energy
• D. Strategies for smoking cessation

Correct answer: B

Rationale: In this scenario, the priority for the nurse to emphasize in the discharge teaching plan is the 'Guidelines for oxygen use.' As the client with emphysema is being discharged with oxygen therapy, it is crucial for the nurse to ensure that the client understands how to use oxygen properly to prevent complications and promote effective management of the condition. While weight loss, conserving energy, and smoking cessation are important aspects of care for this client, in this specific case, ensuring the safe and appropriate use of supplemental oxygen takes precedence to optimize the client's respiratory function and overall well-being.

4. After delegating to an unlicensed assistive personnel (UAP) the task of completing a bladder scan examination for a client, the nurse evaluates the UAP’s performance. Which action by the UAP indicates the nurse must provide additional instructions when delegating this task?

• A. Selecting the female icon for all female clients and the male icon for all male clients
• B. Explaining to the client, 'This test measures the amount of urine in your bladder.'
• C. Applying ultrasound gel to the scanning head and cleaning it after use
• D. Taking at least two readings using the aiming icon to position the scanning head

Correct answer: A

Rationale: The correct answer is A because the UAP should select the female icon for women who have not had a hysterectomy to allow the scanner to subtract the volume of the uterus from readings. If a woman has had a hysterectomy, the UAP should choose the male icon. Choice B is incorrect as it is essential for the UAP to explain the procedure to the client to ensure understanding. Choice C is incorrect because applying ultrasound gel to the scanning head and cleaning it after use are appropriate actions. Choice D is incorrect as it is necessary for the UAP to take at least two readings using the aiming icon to position the scanning head accurately for an effective bladder scan examination.

5. The nurse is caring for a client with chronic renal failure who is on a low-potassium diet. Which of the following foods should the client avoid?

• A. Bananas
• B. Potatoes
• C. Rice
• D. Apples

Correct answer: A

Rationale: Bananas are high in potassium content, which can lead to hyperkalemia in clients with chronic renal failure who are on a low-potassium diet. Therefore, it is crucial for these clients to avoid bananas. Potatoes, rice, and apples are lower in potassium compared to bananas and are generally considered safe for consumption in clients with chronic renal failure on a low-potassium diet.
