Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has hypokalemia. Which of the following findings should the nurse expect?

• A. Serum potassium 5.4 mEq/L
• B. Flat T waves
• C. Elevated ST segments
• D. Bradycardia

Correct answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

2. A nurse is caring for a client who is at risk for pressure ulcers. Which of the following interventions should the nurse implement?

• A. Turn the client every 2 hours
• B. Use a donut-shaped cushion when sitting
• C. Elevate the head of the bed to 45 degrees
• D. Massage reddened areas to increase circulation

Correct answer: A

Rationale: The correct intervention for preventing pressure ulcers in a client at risk is to turn the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and preventing tissue damage. Using a donut-shaped cushion can actually increase pressure on the skin and worsen the risk of pressure ulcers. Elevating the head of the bed to 45 degrees is beneficial for preventing aspiration in some cases but does not directly address pressure ulcer prevention. Massaging reddened areas can further damage the skin and increase the risk of pressure ulcer development by causing friction and shearing forces.

3. A nurse is caring for a client who has a prescription for clozapine. Which of the following laboratory values should the nurse monitor?

• A. Monitor blood glucose levels
• B. Monitor WBC count
• C. Monitor platelet count
• D. Monitor hemoglobin levels

Correct answer: B

Rationale: The correct answer is to monitor the WBC count. Clozapine can cause agranulocytosis, a severe decrease in WBC count, which can increase the risk of infection. Monitoring the WBC count is essential to detect this potentially life-threatening condition early. Monitoring blood glucose levels (Choice A) is not directly related to clozapine use. Platelet count (Choice C) and hemoglobin levels (Choice D) are not typically affected by clozapine and are not the priority for monitoring in this case.

4. A nurse is assisting with the development of an informed document for participation in a research study. Which of the following information should the nurse include?

• A. A statement that participants can leave the study at will.
• B. An assignment of the participant to either the experimental or control group.
• C. A list of the clients participating in the study.
• D. A description of the framework the researchers will use to evaluate the data.

Correct answer: A

Rationale: The correct answer is A: 'A statement that participants can leave the study at will.' This information is crucial to include in the informed document to ensure that participants are aware of their right to withdraw from the study at any time without any negative consequences. Choice B is incorrect because participants should not be assigned to experimental or control groups without their knowledge and consent. Choice C is incorrect because disclosing a list of clients participating in the study violates confidentiality. Choice D is incorrect as the description of the data evaluation framework is important but not as critical as ensuring participants know they can leave the study at will.

5. What is the appropriate action for a patient experiencing a severe allergic reaction?

• A. Administer epinephrine
• B. Administer antihistamines
• C. Administer corticosteroids
• D. Administer oxygen

Correct answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.
