Nursing Elites

1. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

2. A client with a diagnosis of chronic heart failure is prescribed digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure
• B. Assess heart rate
• C. Monitor respiratory rate
• D. Measure oxygen saturation

Correct answer: B

Rationale: The correct answer is to assess the heart rate before administering digoxin. Digoxin can lead to bradycardia, making it crucial to evaluate the heart rate to prevent potential complications. Checking blood pressure (Choice A) is important but not as critical as assessing the heart rate in this context. Monitoring respiratory rate (Choice C) and measuring oxygen saturation (Choice D) are not the most crucial assessments before administering digoxin, as the primary concern with this medication is its impact on heart rate.

3. A client presents to the emergency department with symptoms of a myocardial infarction. What should the nurse administer immediately under doctor's orders?

• A. Aspirin to prevent further blood clotting
• B. High-flow oxygen
• C. Intravenous fluids
• D. Nitroglycerin

Correct answer: A

Rationale: The correct answer is A: Aspirin to prevent further blood clotting. Administering aspirin is crucial in the immediate management of a myocardial infarction as it helps prevent further blood clot formation, which is a key component in the treatment and prevention of myocardial infarction. Oxygen therapy (Choice B) is often provided, but aspirin takes precedence due to its role in reducing clot formation. Intravenous fluids (Choice C) may be needed but are not the immediate priority in this situation. Nitroglycerin (Choice D) is commonly used for chest pain relief in myocardial infarction but is not the first medication to be administered in this scenario.

4. A healthcare provider is conducting a health education session about the prevention of type 2 diabetes. What lifestyle modification should be emphasized?

• A. Increasing physical activity
• B. Reducing dietary sugar intake
• C. Regular health screenings
• D. All of the above

Correct answer: D

Rationale: To effectively prevent type 2 diabetes, individuals should focus on a combination of lifestyle modifications. Increasing physical activity helps maintain a healthy weight and improves insulin sensitivity. Reducing dietary sugar intake can lower the risk of developing diabetes by managing blood sugar levels. Regular health screenings are crucial for early detection and timely intervention. Emphasizing all these modifications together provides a comprehensive approach to diabetes prevention. Choices A, B, and C are all important components of a healthy lifestyle that can contribute to reducing the risk of type 2 diabetes.

5. The nurse is caring for a client who has just returned from surgery with a urinary catheter in place. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs)?

• A. Irrigate the catheter daily
• B. Ensure the catheter bag is always below bladder level
• C. Change the catheter every 48 hours
• D. Administer prophylactic antibiotics

Correct answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.
