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. The client with diabetes is being taught about the importance of foot care. Which statement by the client indicates a need for further teaching?

• A. ''I will inspect my feet daily for any cuts or blisters.''
• B. ''I will soak my feet in warm water every day.''
• C. ''I will wear shoes that fit properly to avoid injury.''
• D. ''I will avoid walking barefoot to protect my feet.''

Correct answer: B

Rationale: Choice B is the correct answer because soaking feet daily can lead to skin breakdown, making it inappropriate for clients with diabetes. Inspecting feet daily for cuts or blisters (Choice A), wearing properly fitting shoes (Choice C), and avoiding walking barefoot (Choice D) are all appropriate measures to maintain foot health for clients with diabetes.

3. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

• A. Increases joint lubrication
• B. Reduces inflammation by suppressing the immune system
• C. Enhances bone density
• D. Stimulates cartilage regeneration

Correct answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.

4. What is the priority nursing action during the immediate postoperative period for a client who just underwent a coronary artery bypass graft?

• A. Monitor for signs of infection
• B. Ensure the client is pain-free
• C. Assess for bleeding and arrhythmias
• D. Maintain a patent airway

Correct answer: D

Rationale: Maintaining a patent airway is the priority nursing action during the immediate postoperative period for a client who just underwent a coronary artery bypass graft. This is crucial to ensure adequate oxygenation, especially in the early recovery phase. Monitoring for signs of infection, ensuring the client is pain-free, and assessing for bleeding and arrhythmias are important aspects of postoperative care but maintaining a clear airway takes precedence in this scenario to prevent hypoxia and respiratory compromise. In the immediate postoperative period, maintaining a patent airway is essential to prevent complications such as airway obstruction, hypoxia, and respiratory distress, which are critical in ensuring the client's safety and recovery.

5. The nurse is caring for a client who has just returned from surgery with an indwelling urinary catheter in place. What is the most important assessment for the nurse to make?

• A. Check for catheter patency
• B. Assess the color of the urine
• C. Measure the urine output
• D. Ensure the catheter tubing is secure

Correct answer: C

Rationale: The most important assessment for the nurse to make in this situation is to measure the urine output. This assessment is crucial in monitoring kidney function and fluid balance after surgery. While checking for catheter patency is important, it is not as critical as measuring urine output. Assessing the color of the urine can provide some information about kidney function, but measuring output gives a more accurate assessment. Ensuring the catheter tubing is secure is essential to prevent dislodgement but is not the most critical assessment to make at this time.
