Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?

• A. Avoid close contact with others until treatment is complete
• B. Take all prescribed medications as directed
• C. Schedule a follow-up appointment with the healthcare provider
• D. Wear a mask when in public places

Correct answer: B

Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.

3. The nurse is assessing a client who has been diagnosed with chronic obstructive pulmonary disease (COPD). Which clinical finding is characteristic of this condition?

• A. Pursed-lip breathing
• B. Hyperresonance on percussion
• C. Bradycardia
• D. High-pitched inspiratory crackles

Correct answer: A

Rationale: Pursed-lip breathing is a characteristic finding in clients with COPD. It helps keep the airways open during exhalation, acting as a compensatory mechanism to prevent airway collapse, which is common in COPD. Hyperresonance on percussion is typically found in conditions like emphysema, which is a component of COPD but not characteristic of the overall disease. Bradycardia is not typical in COPD; instead, clients often exhibit tachycardia due to chronic hypoxemia. High-pitched inspiratory crackles are more commonly associated with conditions like pneumonia, not COPD.

4. The nurse is caring for a client with a chest tube after thoracic surgery. What is the most important assessment related to the chest tube?

• A. Ensure continuous bubbling in the water seal chamber
• B. Measure the amount of drainage every shift
• C. Keep the drainage system at the level of the chest
• D. Assess for subcutaneous emphysema around the insertion site

Correct answer: D

Rationale: The most important assessment related to a chest tube after thoracic surgery is to assess for subcutaneous emphysema around the insertion site. Subcutaneous emphysema can indicate air leakage from the pleural space, which can lead to serious complications such as a pneumothorax. Ensuring continuous bubbling in the water seal chamber is not the most critical assessment as it is a normal finding in a chest drainage system. While measuring the amount of drainage is important to monitor the client's condition, it is not as crucial as assessing for subcutaneous emphysema. Keeping the drainage system at the level of the chest helps maintain proper function but is not the most critical assessment in this scenario.

5. Which nursing activity is within the scope of practice for the practical nurse?

• A. Complete an admission assessment in the normal newborn nursery
• B. Discontinue a central venous catheter that has become dislodged
• C. Observe a client rotate the subcutaneous site for an insulin pump
• D. Monitor a continuous narcotic epidural for a postoperative client

Correct answer: C

Rationale: The correct answer is C: 'Observe a client rotate the subcutaneous site for an insulin pump.' This activity is within the scope of practice for a practical nurse as it involves observing and ensuring proper technique for using an insulin pump, which aligns with their training and responsibilities. Choices A, B, and D are beyond the typical scope of practice for a practical nurse. Completing an admission assessment for a newborn nursery is usually performed by a registered nurse. Discontinuing a dislodged central venous catheter and monitoring a narcotic epidural require advanced skills and knowledge, usually carried out by registered nurses or advanced practice nurses.
