Nursing Elites

1. A client with a diagnosis of coronary artery disease is receiving atorvastatin (Lipitor). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?

• A. Complete blood count (CBC)
• B. Serum potassium level
• C. Liver function tests (LFTs)
• D. Serum cholesterol level

Correct answer: C

Rationale: To evaluate the effectiveness of atorvastatin (Lipitor), the nurse should monitor liver function tests (LFTs) (C) because this medication can impact liver function. Complete blood count (CBC) (A), serum potassium level (B), and serum cholesterol level (D) are not directly indicative of the medication's effectiveness in managing coronary artery disease.

2. The client is being taught how to self-administer a subcutaneous injection. To ensure sterility of the procedure, which subject is most important for the instructor to include in the teaching plan?

• A. Hand washing before preparing the injection.
• B. Technique for drawing medication from a vial.
• C. Selection and rotation of injection sites.
• D. Proper disposal of injection equipment.

Correct answer: B

Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial. This ensures that the medication remains sterile during preparation and administration. While hand washing, injection site selection, and equipment disposal are important aspects of injection safety, the key focus should be on maintaining the sterility of the medication itself to prevent infections and ensure the effectiveness of the treatment.

3. A client with frequent urinary tract infections (UTIs) asks the nurse about drinking juice daily to prevent future UTIs. Which response is best for the nurse to provide?

• A. Orange juice has vitamin C, which deters bacterial growth.
• B. Apple juice is the most useful in acidifying the urine.
• C. Cranberry juice stops pathogens' adherence to the bladder.
• D. Grapefruit juice increases the absorption of most antibiotics.

Correct answer: C

Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs. Choices A, B, and D are incorrect because while vitamin C in orange juice may have some benefits, it is not specifically known for deterring bacterial growth in the urinary tract. Apple juice does not significantly impact urine acidity, and grapefruit juice does not enhance antibiotic absorption, making them less effective choices for preventing UTIs compared to cranberry juice.

4. When caring for a client with a chest tube, which intervention is most important?

• A. Keep the drainage system at chest level.
• B. Ensure that the chest tube is clamped at all times.
• C. Strip the chest tube every shift.
• D. Ensure that the chest tube is connected to a water-seal drainage system.

Correct answer: D

Rationale: The most crucial intervention when caring for a client with a chest tube is to ensure that the chest tube is connected to a water-seal drainage system (D). This system helps maintain proper lung expansion and prevents complications. Keeping the drainage system at chest level (A) is important to facilitate drainage, but not as critical as ensuring the connection to the drainage system. Clamping the chest tube (B) is unnecessary and can lead to serious issues. Stripping the chest tube (C) is an outdated practice and can cause harm rather than benefit.

5. A healthcare professional is working in an occupational health clinic when an employee walks in and states that he was struck by lightning while working in a truck. The client is alert but reports feeling faint. Which assessment will the healthcare professional perform first?

• A. Pulse characteristics
• B. Open airway
• C. Entrance and exit wounds
• D. Cervical spine injury

Correct answer: A

Rationale: When a person is struck by lightning, it can cause an electrical shock that may affect the heart rhythm. Therefore, assessing pulse characteristics is crucial as lightning can act as a natural defibrillator. Monitoring the pulse rate and regularity will help determine if there are any cardiac abnormalities that need immediate attention. Open airway, entrance and exit wounds, and cervical spine injury assessments are also important but assessing pulse characteristics takes precedence in this situation to address potential cardiac issues.
