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. A client is scheduled for a colonoscopy. What instruction should the nurse provide to prepare the client for the procedure?

• A. Drink clear liquids for 24 hours before the procedure
• B. Take a laxative the morning of the procedure
• C. Eat a light meal before the procedure
• D. Avoid drinking fluids for 4 hours before the procedure

Correct answer: A

Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.

3. Which instruction is most important for the nurse to include when teaching a client with limited mobility strategies to prevent venous thrombosis?

• A. Perform cough and deep breathing exercises hourly.
• B. Turn from side to side in bed at least every 2 hours.
• C. Dorsiflex and plantarflex the feet 10 times each hour.
• D. Drink approximately 4 ounces of water every hour.

Correct answer: C

Rationale: The most crucial instruction for a client with limited mobility to prevent venous thrombosis is to perform dorsiflexion and plantarflexion of the feet 10 times each hour. These exercises help promote venous return, reducing the risk of thrombosis by preventing blood stasis in the lower extremities. While other measures like turning in bed and staying hydrated are beneficial, promoting venous return through foot exercises is the priority in preventing venous thrombosis in clients with limited mobility. Dorsiflexion and plantarflexion directly target the calf muscle pump, aiding in the circulation of blood back to the heart and preventing clot formation. The other options, such as cough and deep breathing exercises, turning in bed, and hydration, are important for overall health but do not directly address venous stasis and thrombosis prevention in the same way as foot exercises.

4. When is the first dose of Hepatitis B vaccine typically administered?

• A. In the hospital at birth
• B. At one year old
• C. At six months
• D. At 18 months

Correct answer: A

Rationale: The first dose of the Hepatitis B vaccine is usually administered at birth in the hospital to provide early protection against the virus. Giving the vaccine at birth helps prevent perinatal transmission of Hepatitis B from an infected mother to her newborn. This early administration is crucial in establishing immunity in infants, as delaying the vaccine increases the risk of infection. Options B, C, and D are incorrect because delaying the administration of the Hepatitis B vaccine can leave infants vulnerable to the virus during the critical early months of life when they are most susceptible.

5. The client has a chest tube. What is the most important action for the nurse to take?

• A. Ensure the chest tube remains unclamped at all times.
• B. Empty the chest tube every 2 hours.
• C. Keep the drainage system below the level of the chest.
• D. Assess for subcutaneous emphysema.

Correct answer: C

Rationale: Keeping the drainage system below the level of the chest (C) is crucial to ensure proper drainage and prevent backflow of air or fluid into the chest cavity. This position helps maintain the integrity of the closed drainage system. Ensuring the chest tube remains unclamped at all times (A) allows for continuous drainage. Emptying the chest tube (B) should be done as needed, not routinely every 2 hours. Assessing for subcutaneous emphysema (D) is important but not the most critical action in this scenario.
