Nursing Elites

1. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?

• A. To promote oxygenation by removing secretions.
• B. To reduce the amount of air trapped in the lungs.
• C. To increase the amount of carbon dioxide exhaled.
• D. To slow the respiratory rate and improve air exchange.

Correct answer: C

Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.

2. After ensuring correct tube placement, what action should the nurse take next when administering medications through a nasogastric tube (NGT) connected to suction?

• A. Clamp the tube for 20 minutes.
• B. Flush the tube with water.
• C. Administer the medications as prescribed.
• D. Crush the tablets and dissolve in sterile water.

Correct answer: B

Rationale: After ensuring the correct placement of the NGT, the nurse should flush the tube with water to prevent any obstructions and ensure proper medication delivery. Flushing the tube is essential before, after, and in between each medication administration. Clamping the tube for 20 minutes should be done after all medications are administered to prevent clogging. Administering medications as prescribed and preparing medications by crushing tablets and dissolving them in sterile water should only be done after the tube has been appropriately flushed to maintain its patency and effectiveness.

3. The healthcare provider is providing wound care to a client with a stage 3 pressure ulcer that has a large amount of eschar. The wound care prescription states 'clean the wound and then apply collagenase.' Collagenase is a debriding agent. The prescription does not specify a cleaning method. Which technique should the healthcare provider use to cleanse the pressure ulcer?

• A. Lightly coat the wound with povidone-iodine solution
• B. Irrigate the wound with sterile normal saline
• C. Flush the wound with sterile hydrogen peroxide
• D. Remove the eschar with a wet-to-dry dressing

Correct answer: B

Rationale: The correct technique to cleanse a wound when the prescription does not specify a cleaning method is to irrigate the wound with sterile normal saline. Sterile normal saline is the preferred solution for wound cleaning as it is gentle and does not damage healthy tissues. It helps in removing debris and maintaining a moist environment conducive to healing. Povidone-iodine solution and hydrogen peroxide can be harsh on tissues and delay wound healing. Removing eschar with a wet-to-dry dressing is a mechanical debridement method and should not be done without proper assessment and healthcare provider's order.

4. When taking a client's blood pressure, the healthcare professional is unable to distinguish the point at which the first sound was heard. What is the best action for the healthcare professional to take?

• A. Deflate the cuff completely and immediately reattempt the reading.
• B. Reinflate the cuff completely and leave it inflated for 90 to 110 seconds before taking the second reading.
• C. Deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading.
• D. Document the exact level visualized on the sphygmomanometer where the first fluctuation was seen.

Correct answer: C

Rationale: The correct action when unable to distinguish the point of the first sound during blood pressure measurement is to deflate the cuff to zero and wait 30 to 60 seconds before reattempting the reading. This allows blood flow to return to the extremity, ensuring a more accurate reading the second time. It is important to ensure that the cuff is fully deflated and the appropriate wait time is given to obtain an accurate blood pressure measurement.

5. The client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which intervention should the nurse implement to ensure the client’s safety?

• A. Encourage the client to use oxygen continuously
• B. Monitor the client’s respiratory rate and effort
• C. Set the oxygen flow rate at 6 liters per minute
• D. Teach the client to avoid wearing wool blankets

Correct answer: B

Rationale: Monitoring the client’s respiratory rate and effort is essential to evaluate the effectiveness of oxygen therapy and prevent complications such as respiratory depression. This intervention helps the nurse promptly detect any deterioration in the client's respiratory status and take necessary actions to ensure the client's safety. Encouraging continuous oxygen use (Choice A) may lead to oxygen toxicity. Setting the oxygen flow rate at a specific level (Choice C) without individual assessment can be inappropriate and potentially harmful. Teaching the client to avoid wearing wool blankets (Choice D) is unrelated to the safe use of oxygen therapy.
