Nursing Elites

1. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

2. The nurse is preparing a client for surgery who was admitted to the emergency center following a motor vehicle collision. The client has an open fracture of the femur and is bleeding moderately from the bone protrusion site.

• A. Ensure the client is NPO and document the last meal.
• B. Administer pain medication as prescribed.
• C. Apply a sterile dressing to the wound site.
• D. Notify the healthcare provider of the client’s medication history.

Correct answer: D

Rationale: In this scenario, the priority action is to notify the healthcare provider of the client's medication history. This is important because understanding the client’s medication history, especially if they are taking anticoagulants or other medications that could affect bleeding and surgery, is crucial in ensuring safe management of the client's condition. Option A, ensuring the client is NPO and documenting the last meal, is important but not the priority in this situation. Administering pain medication (Option B) should only be done after ensuring the client's safety and stability. Applying a sterile dressing (Option C) is also important but not as critical as informing the healthcare provider of the medication history.

3. A client who is newly diagnosed with emphysema is being prepared for discharge. Which instruction is best for the nurse to provide the client to assist them with dyspnea self-management?

• A. Allow additional time to complete physical activities to reduce oxygen demand.
• B. Practice inhaling through the nose and exhaling slowly through pursed lips.
• C. Use a humidifier to increase home air quality humidity between 30-50%.
• D. Strengthen abdominal muscles by alternating leg raises during exhalation.

Correct answer: B

Rationale: The correct answer is B. Instructing the client to practice inhaling through the nose and exhaling slowly through pursed lips can help improve oxygenation and reduce dyspnea. This technique, known as pursed lip breathing, can help regulate breathing patterns and decrease the work of breathing in clients with emphysema. Choice A is incorrect because allowing additional time for physical activities does not directly address dyspnea management. Choice C is incorrect as using a humidifier, although beneficial for respiratory conditions, does not specifically assist with dyspnea self-management. Choice D is also incorrect as strengthening abdominal muscles through leg raises does not directly target dyspnea relief.

4. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.

5. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
