Nursing Elites

1. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

2. A nurse receives a report about a client receiving IV fluids infusing at 125 mL/hr but notes they have only received 80 mL over the last 2 hours. What should the nurse do first?

• A. Check IV tubing for obstruction
• B. Increase the flow rate
• C. Change the IV site
• D. Notify the physician

Correct answer: A

Rationale: The correct first action for the nurse to take is to check the IV tubing for obstruction. This step is crucial in ensuring that the IV fluids are flowing properly and that there are no blockages preventing the correct infusion rate. Increasing the flow rate (Choice B) without confirming the tubing's status could lead to potential complications if there is indeed an obstruction. Changing the IV site (Choice C) is not the priority in this situation unless there are specific clinical indications. Notifying the physician (Choice D) can be done after checking the tubing for obstruction, as the physician may need to be informed depending on the findings.

3. The nurse is caring for a patient who is immobile and needs to be turned every 2 hours. The patient has poor lower extremity circulation, and the nurse is concerned about irritation of the patient's toes. Which device will the nurse use?

• A. Hand rolls
• B. A foot cradle
• C. A trapeze bar
• D. A trochanter roll

Correct answer: B

Rationale: A foot cradle is the correct choice for this situation. A foot cradle is used to reduce pressure on the tips of a patient's toes in individuals with poor lower extremity circulation. Hand rolls are not designed to address toe irritation specifically. A trapeze bar is used to assist patients with repositioning in bed, and a trochanter roll is used to support the hips and prevent external rotation of the legs, neither of which directly address toe irritation in this scenario.

4. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 0.5 mL
• B. 1 mL
• C. 1.5 mL
• D. 2 mL

Correct answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

5. A nurse is caring for a group of clients. How should the nurse prevent the spread of infection?

• A. Place a client with TB in a negative pressure room.
• B. Use standard precautions only.
• C. Place a client with TB in a private room.
• D. Use barrier precautions only.

Correct answer: A

Rationale: The correct answer is to place a client with TB in a negative pressure room. Tuberculosis (TB) is an airborne infectious disease, and placing the client in a negative pressure room helps prevent the spread of the infection by containing and filtering the air within the room. Standard precautions (Choice B) are important for preventing the spread of infection in general, but specific precautions are needed for airborne diseases like TB. Placing the client in a private room (Choice C) may not provide adequate ventilation and containment of airborne pathogens. Using barrier precautions (Choice D) alone is not sufficient for preventing the airborne transmission of TB.
