Nursing Elites

1. The nurse is caring for a newly admitted patient who has severe gastroenteritis. The patient’s electrolytes reveal a serum sodium level of 140 mEq/L and a serum potassium level of 3.5 mEq/L. The nurse receives an order for intravenous 5% dextrose and normal saline with 20 mEq/L potassium chloride to infuse at 125 mL per hour. Which action is necessary prior to administering this fluid?

• A. Evaluate the patient’s urine output.
• B. Contact the provider to order arterial blood gases.
• C. Request an order for an initial potassium bolus.
• D. Suggest a diet low in sodium and potassium.

Correct answer: A

Rationale: Prior to administering IV fluids containing potassium, it is crucial to evaluate the patient's urine output. If the urine output is less than 25 mL/hr or 600 mL/day, there is a risk of potassium accumulation. Patients with low urine output should not receive IV potassium to prevent potential complications. Contacting the provider for arterial blood gases is unnecessary in this scenario as it does not directly relate to the administration of IV fluids with potassium. Administering potassium as a bolus is not recommended due to potential adverse effects. While dietary considerations are important, suggesting a low-sodium and low-potassium diet is not the immediate action required before administering IV fluids with potassium chloride.

2. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?

• A. Cardiac output.
• B. Right atrial blood flow.
• C. Left end-diastolic pressure.
• D. Cardiac index.

Correct answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

3. During spring break, a young adult presents to the urgent care clinic and reports a stiff neck, a fever for the past 6 hours, and a headache. Which intervention is most important for the nurse to implement first?

• A. Initiate isolation precautions
• B. Administer an antipyretic
• C. Draw blood cultures
• D. Prepare for lumbar puncture

Correct answer: A

Rationale: The correct answer is to initiate isolation precautions. This is the priority action because the patient presents with symptoms that could be indicative of meningitis, an infectious disease that requires isolation to prevent its spread. Administering an antipyretic (Choice B) may help manage the fever but does not address the need for isolation. Drawing blood cultures (Choice C) and preparing for a lumbar puncture (Choice D) are important steps in diagnosing meningitis but should come after initiating isolation precautions to prevent potential transmission of the infection to others.

4. Which of the following is the most important nursing action when administering a blood transfusion?

• A. Monitoring the patient's blood pressure.
• B. Monitoring the patient's temperature.
• C. Monitoring the patient's heart rate.
• D. Monitoring the patient's oxygen saturation.

Correct answer: A

Rationale: The most important nursing action when administering a blood transfusion is monitoring the patient's blood pressure. This is crucial because monitoring blood pressure allows for the prompt identification of any signs of adverse transfusion reactions, such as transfusion reactions or fluid overload. Immediate intervention can be initiated if any complications arise. While monitoring temperature, heart rate, and oxygen saturation are also essential aspects of patient care, they are not as critical as blood pressure monitoring during a blood transfusion. Therefore, the correct answer is to monitor the patient's blood pressure.

5. A client has just undergone insertion of a chest tube that is attached to a closed chest drainage system. Which action should the nurse plan to take in the care of this client?

• A. Assessing the client’s chest for crepitus every 24 hours
• B. Taping the connections between the chest tube and the drainage system
• C. Adding 20 mL of sterile water to the suction control chamber every shift
• D. Recording the volume of secretions in the drainage collection chamber every 24 hours

Correct answer: B

Rationale: The correct action for the nurse to take in caring for a client with a chest tube connected to a closed chest drainage system is to tape the connections between the chest tube and the drainage system. This is done to prevent accidental disconnection, ensuring the system functions properly. Assessing the client’s chest for crepitus should be done more frequently than once every 24 hours to monitor for any air leaks. Adding sterile water to the suction control chamber is not necessary every shift; it should be done as needed to maintain the appropriate water level. Recording the volume of secretions in the drainage collection chamber should be done more frequently than every 24 hours, with hourly monitoring during the first 24 hours after insertion and every 8 hours thereafter to assess for changes or complications.
