Nursing Elites

1. A child is injured on the school playground and appears to have a fractured leg. What action should the school nurse take first?

• A. Call for emergency transport to the hospital
• B. Immobilize the limb and joints above and below the injury
• C. Assess the child and the extent of the injury
• D. Apply cold compresses to the injured area

Correct answer: C

Rationale: The correct first action for the school nurse to take when a child is injured and appears to have a fractured leg is to assess the child and the extent of the injury. This initial assessment is crucial to determine the severity of the injury before proceeding with further interventions. Option A, calling for emergency transport, should only be done after assessing the extent of the injury. Option B, immobilizing the limb and joints, is important but should come after the initial assessment. Option D, applying cold compresses, is not recommended for suspected fractures as it can exacerbate swelling and pain.

2. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

3. 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.

4. A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?

• A. Thermometer
• B. Elastic stockings
• C. Blood pressure cuff
• D. Sequential compression devices

Correct answer: C

Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.

5. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

• A. Decrease in heart rate
• B. Fluid volume deficit causes tachycardia
• C. Decrease in blood pressure
• D. Increase in respiratory rate

Correct answer: A

Rationale: A decrease in heart rate can indicate that the fluid volume deficit is improving. In cases of fluid volume deficit, the body compensates by increasing the heart rate to maintain adequate perfusion. Therefore, a decrease in heart rate after fluid resuscitation suggests that the body's perfusion status is improving. Choices B, C, and D are incorrect because fluid volume deficit typically causes tachycardia, not a decrease in heart rate, and would not result in a decrease in blood pressure or an increase in respiratory rate as primary signs of improvement.
